Rail Safety National Law Application Act 2024

The Act rests on three core conceptual mechanisms: imported national Law, conditional local application of later national amendments, and bespoke local testing rules.

Imported national Law. Section 5 imports the Rail Safety National Law as it stood on 20 June 2023, including the Rail Safety National Law (South Australia) (Fees) Amendment Act 2023, and any later amending Acts that acquire effect for WA under the Act’s procedures (s 5(1)). The imported Law is treated as an Act of WA (s 5(2)(c)), which has the practical consequence that the national regulatory framework, offences, accreditation and regulator powers in the Schedule become enforceable in WA subject to the modifications in this Act.

Conditional local application of later amendments. The Act does not adopt later South Australian amendments automatically. Instead it sets out a parliamentary oversight mechanism. An amending Act must be laid before both Houses within 18 sitting days (s 7). It will have effect for WA only if no notice to disallow is given within the specified notice period, or any such disallowance is withdrawn or fails within the disallowance period (s 8). The Governor must proclaim when an amending Act has effect for WA and set commencement dates for its provisions (s 9). This creates a system in which WA adopts the national Law as a moving body of law subject to parliamentary scrutiny and proclamation.

National Regulations as subsidiary legislation. Section 12 provides that regulations made under the national Law (the Rail Safety National Regulations) apply as subsidiary legislation in WA and are to be referred to as the Rail Safety National Regulations (WA). The Act contains rules about the timing of publication (s 15), tabling before Parliament (s 16(1)) and automatic cessation where the regulations are not published or are disallowed (s 16(2)). Section 17 carves out s 41 and 42 of the Interpretation Act 1984 from applying to the Rail Safety National Regulations (WA).

Local alcohol and drug testing regime. Part 3 sets out comprehensive local rules governing testing powers. It defines technical terms for devices and personnel (s 21), sets the statutory conversion between breath and blood alcohol measurements (s 22), allows both random and non‑random testing in specified circumstances (ss 24 and 31), imposes a 12 hour outer window for compulsory testing in many cases (ss 25, 32, 39), creates health and incapacity exemptions (ss 26, 33), regulates who may operate analysis devices and perform breath or oral fluid analysis (ss 27, 34), and controls blood sampling where workers are injured or deceased (ss 40-41). The Act also addresses evidentiary presumptions and the admissibility of test results in court proceedings (ss 42-45).

Exclusions and administrative framing. The Act excludes several WA statutes from applying to the Rail Safety National Law (WA) except as applied by that Law (s 20(2)), and specifies that the Office of the National Rail Safety Regulator and its employees are not public sector agencies or officers for the purposes of the Public Sector Management Act (s 18(2)). The Act also defines which WA courts count as the relevant "court" for particular parts of the national Law (s 18(1)).

Together these concepts create a legal architecture in which a nationally drafted rail safety code operates within WA subject to parliamentary oversight of subsequent national amendments and with local procedural and evidentiary rules for testing.

Rail transport operators and rail infrastructure managers. The imported national Law governs accreditation, registration and safety duties for rail transport operators and rail infrastructure managers because the national Law is applied in WA as if it were an Act (s 5(2)(c)). Transitional provisions treat pending accreditation or registration applications commenced under the former Law as if made under the new Law and require the Regulator to continue consideration (s 52). That means operators and infrastructure managers must comply with the substantive national Law as applied in WA, and adjust to the procedural changes in the new Act.

Rail safety workers. Part 3 directly affects rail safety workers by regulating when and how they may be required to submit to alcohol and drug testing. The Act permits random and non‑random preliminary breath tests, breath analyses, drug screening tests or oral fluid analyses, and blood tests in specified circumstances (ss 24, 31, 36-38). It defines when workers are not obliged to comply, for example if more than 12 hours have elapsed since the worker last performed rail safety work, or after a shift ended and the worker had left and was unaware of a notifiable occurrence (ss 25(1)-(2), 32(1)-(2), 39(1)-(2)). Workers are also protected where complying would be detrimental to health or where they cannot provide sufficient samples due to injury, disability or other reasons (ss 26, 33).

Authorised persons and the Regulator. Authorised persons exercise powers to require testing (ss 23, 30, 35) and must observe constraints on when requirements may be made (ss 24, 31, 36-39). The Regulator authorises persons to operate breath analysis instruments and oral fluid analysis devices (ss 27(1)(b), 34(1)(b)), certifies authorised persons, and plays an evidentiary role via certificates (s 45). The Act also determines that the Office of the National Rail Safety Regulator and its employees are not public service agencies or officers under WA public sector legislation (s 18(2)). That affects employment status and administrative oversight.

Police. The Commissioner of Police may certify police officers as competent to operate breath analysis instruments or oral fluid analysis devices (ss 27(2), 34(2)). The Commissioner may delegate that certification to members at or above Inspector (s 46). Police officers certified by the Commissioner may conduct breath or oral fluid analyses under the Act (ss 27(1)(a), 34(1)(a)).

Hospitals, medical practitioners, sample takers and analysts. The Act authorises sample takers, including medical practitioners and registered nurses, to take blood samples in hospital settings and in certain post‑mortem contexts (ss 21, 40-41). Analysts and the chief executive of the Chemistry Centre (WA) are specified as evidentiary declarants for certificates about analysis competency and results (s 45(1)(b), (f)).

Courts, tribunal and parliamentary actors. The Act defines which WA judicial bodies constitute "the court" for different parts of the national Law. For example, Part 5 Division 6 references the State Administrative Tribunal constituted by at least one judicial member, Part 7 references the State Administrative Tribunal however constituted, and Part 10 Division 6 references the Magistrates Court (s 18(1)(a)-(c)). Parliamentarians and committees are involved in tabling and disallowance procedures for amending Acts and Regulations (ss 7-9, 15-16, 11).

Public sector auditors and FOI/oversight bodies. Several WA statutes are excluded from applying to the Rail Safety National Law (WA) and its instruments except as applied under that Law. The list includes the Auditor General Act 2006, Financial Management Act 2006, Freedom of Information Act 1992, Parliamentary Commissioner Act 1971, Public Sector Management Act 1994 and State Records Act 2000 (s 20(2)). The Act does, however, state that those Acts apply to a public sector body and its employees performing a function under the Rail Safety National Law (WA) as defined in the Public Sector Management Act where applicable (s 20(3)). The Office of the National Rail Safety Regulator and its employees are not public sector bodies or public service officers for the purposes of the Public Sector Management Act (s 18(2)).

Employers, unions and legal advisers. Employers need operational policies reflecting the 12 hour windows, health exceptions and procedures for conducting tests. Unions and representatives will engage with application of testing powers. Legal advisers and coroners are affected by evidentiary presumptions in s 43, restrictions on admissibility in s 44, certification rules in s 45 and coronial blood sampling directions in s 41.

Passengers and the general public. The Act alters the legal framework governing rail safety, which indirectly affects passengers and the public by changing regulatory oversight, testing and investigatory powers following notifiable occurrences.

Parliament and the WA public. The Act requires tabling of amending Acts and Regulations and creates a disallowance mechanism (ss 7-9, 15-16). That means Parliament retains a structured avenue to scrutinise or disallow South Australian amending Acts and national Regulations as they are applied in WA.

Application and precedence duties. The central duty created is that persons and entities within WA must comply with the Rail Safety National Law as applied by this Act (s 5(2)). Where the Rail Safety National Law conflicts with the Government Railways Act 1904 the national Law prevails (s 57(2) inserts new s 2A into the Government Railways Act 1904). That places a statutory duty on public and private rail operators to follow the national safety framework as it applies in WA.

Testing powers and limits. Authorised persons may require rail safety workers to submit to preliminary breath tests, breath analyses, drug screening tests, oral fluid analyses, urine tests or blood tests under the relevant national Law sections as subject to Part 3 of this Act (ss 23, 30, 35). The Act clarifies when such requirements may be imposed. Random testing is permitted without reasonable suspicion for both alcohol and drug screening (ss 24(1)(a), 31(1)(a)). Non‑random tests can be required following notifiable occurrences or where there are reasonable grounds to suspect alcohol or drugs (ss 24(1)(b), 31(1)(b)). The Act also authorises requiring further breath analyses (s 28) and blood tests in specified circumstances (ss 36-38).

Rights to refuse or limitations on compulsion. The Act creates specific rights or exemptions for rail safety workers not to comply. A worker on railway premises is not obliged to comply with a testing requirement if more than 12 hours have passed since they last carried out rail safety work and they are not involved in a notifiable occurrence (ss 25(1), 32(1), 39(1)). Where the worker is involved in a notifiable occurrence, a 12 hour limit also applies from the time of the occurrence (ss 25(2)(a), 32(2)(a), 39(2)(a)). A worker who has finished a shift and left the place where the shift ended and was unaware of the notifiable occurrence when they finished the shift is also not obliged to comply (ss 25(2)(b), 32(2)(b), 39(2)(b)). Authorised persons must not require testing if they reasonably suspect that compliance would be detrimental to health or if the worker cannot provide a sufficient sample due to injury, disability or other reason (ss 26, 33).

Operational duties on authorised persons and device operation. An authorised person must use a breath analysis instrument for breath analyses and must be either a police officer certified by the Commissioner of Police or authorised by the Regulator to operate the device (s 27(1)-(3)). Similarly, oral fluid analyses must be conducted by a certified police officer or a Regulator‑authorised operator (s 34(1)-(3)). The Commissioner may certify police officers and may delegate that power in writing to members at or above Inspector (ss 27(2), 34(2), 46(1)-(2)). The Regulator may authorise persons to operate devices (ss 27(1)(b), 34(1)(b)).

Evidence and presumptions. Courts are given statutory presumptions about blood alcohol content and drug presence when tests are conducted under Part 3. In the absence of contrary evidence, a breath analysis result or a blood analysis result taken under this Part is presumed to indicate blood alcohol content at the relevant time (s 43(2)). For drugs, detection in analysis of oral fluid, urine or blood taken under this Part is presumed to indicate the drug was present at the relevant time (s 43(4)). The Act sets limited routes to rebut a breath analysis presumption, namely a blood analysis taken under the Part indicating a different level and evidence that the breath instrument gave an exaggerated reading (s 43(3)). Evidence of breath or blood alcohol content derived from improperly conducted breath tests or non‑instrument devices, or tests by non‑authorised persons, is inadmissible (s 44).

Certificate and disclosure duties. The Act allows specified officials to issue certificates that are evidence of matters stated (s 45(1)). However, certificates by the Regulator, authorised persons or hospital staff cannot be used against a defendant without procedural safeguards: they must be served 7 days before proceedings or the defendant can require the signatory to attend the trial (s 45(2)).

Parliamentary oversight duties. WA Parliament receives amending Acts and Rail Safety National Regulations under specified tabling notice periods (ss 7, 15-16). Failure to publish or table national Regulations within the stated time leads to cessation of effect as subsidiary legislation (s 16(2)). Amending Acts are subject to a notice and disallowance process including defined notice and disallowance periods (s 8).

Exclusions from WA statutes and consequential duties. The Interpretation Act 1984 does not apply to the Rail Safety National Law (WA) (s 20(1)). Several WA Acts do not apply to the Rail Safety National Law (WA) except as applied under the Law (s 20(2)). These exclusions alter duties relating to auditing, financial management, FOI, Ombudsman oversight and public sector management for instruments made under the national Law.

Transitional rights. The Act preserves rights of review and appeal that existed immediately before commencement and provides that pending reviews and appeals continue under the corresponding provisions of the new Law (ss 53-55). Existing applications for accreditation or registration are taken to have been made under the corresponding provisions of the new Law and the Regulator must continue to consider them (s 52).

Enforcement framework. The Act imports the Rail Safety National Law into WA as if it were an Act, thereby making the enforcement regime, including offences and penalties contained in the national Law Schedule, enforceable in WA (s 5(2)(c)). The Act itself does not restate specific penalty amounts or list the full catalogue of offences. Instead it makes the national Law the operative statutory framework and thereby brings into force the regulator’s enforcement powers, powers of authorised persons to require testing, and court and tribunal processes defined in the national Law, as modified by the local provisions in this Act (s 5).

Authorised persons’ enforcement powers. Authorised persons may require rail safety workers to submit to testing under national Law sections as subject to the conditions in Part 3 of this Act (ss 23, 30, 35). Those powers are subject to statutory limits on when tests may be required (ss 24, 31, 36-39), health and incapacity exemptions (ss 26, 33), and the 12 hour timing constraints (ss 25, 32, 39). Failure to comply with a lawful requirement under the national Law may give rise to regulatory action or offences as set out in the national Law. The Act also specifies that if a worker refuses a preliminary breath test or fails to provide a sufficient sample, a blood test may be required in some circumstances (s 36(1)).

Police role and certification. Police officers may conduct breath and oral fluid analyses if certified by the Commissioner of Police (ss 27(1)(a), 34(1)(a)). The Commissioner may delegate certification to officers at or above the rank of Inspector (s 46(1)-(3)). Certification and delegation affect who may lawfully operate devices and thereby bear on admissibility of evidence. Evidence arising from tests must be conducted by authorised persons and using authorised devices, otherwise the test results are inadmissible in proceedings (s 44).

Evidentiary presumptions and criminal process. For prosecutions or other court proceedings relating to rail safety workers, the Act creates evidentiary presumptions that can affect enforcement outcomes. Breath analysis results and blood tests taken under this Part are presumed to reflect the worker’s blood alcohol content at the relevant time, absent contrary evidence (s 43(2)). Similarly, detection of a prescribed drug in samples taken under this Part is presumed to indicate presence at the relevant time (s 43(4)). These presumptions shift evidential burdens and may streamline prosecutions but they can be rebutted under limited conditions, principally by blood analysis results or evidence of instrument exaggeration (s 43(3)). Certificates from specified officials are admissible evidence of testing and device status unless procedural notice and attendance conditions are invoked by a defendant (s 45).

Parliamentary control over regulations. The Act subjects Rail Safety National Regulations to a publication and tabling regime in WA and provides they cease to have effect as subsidiary legislation if not published or if disallowed by Parliament (ss 15-16). That creates an additional political check on regulatory content that can have enforcement consequences if regulations lapse.

No double jeopardy provision. The Act contains an explicit double jeopardy protection which prevents a person from being punished for a Rail Safety National Law (WA) offence if the act or omission also constituted an offence in another participating jurisdiction and the person has already been punished under that other jurisdiction’s law (s 19). That limits the scope of enforcement where multiple jurisdictions might assert penalties.

Administrative oversight and exclusions. The Act excludes several WA oversight and administrative statutes from applying to the Rail Safety National Law (WA) and instruments made under it except insofar as the national Law applies them (s 20(2)). That can affect traditional oversight pathways such as FOI, Parliamentary Commissioner inquiries and Auditor General reviews, potentially constraining certain investigative or audit enforcement avenues at the WA level.

Transitional obligations and ongoing appeals. Transitional provisions preserve rights of review and appeal and require existing reviews and appeals to be continued under corresponding new Law sections (ss 53-55). That ensures enforcement actions already in train remain subject to judicial or tribunal scrutiny.

Precedence and explicit amendments. The Act inserts a new precedence provision into the Government Railways Act 1904 making the Rail Safety National Law (WA) prevail to the extent of any inconsistency (s 57(2)). It also amends various WA Acts to replace references to the repealed 2015 Act with references to the Rail Safety National Law (WA) (s 58). Those consequential amendments align statutory cross‑references and priorities across WA legislation.

Exclusion of WA legislation. Several WA statutes do not apply to the Rail Safety National Law (WA) or instruments made under it, except where applied under the national Law itself. The excluded Acts are the Auditor General Act 2006, Financial Management Act 2006, Freedom of Information Act 1992, Parliamentary Commissioner Act 1971, Public Sector Management Act 1994 and State Records Act 2000 (s 20(2)). However, the Act clarifies that an Act mentioned in s 20(2) applies to a public sector body and its employees performing a function under the Rail Safety National Law (WA) where they are public sector bodies under the Public Sector Management Act (s 20(3)). Additionally, the Act defines that the Office of the National Rail Safety Regulator and its employees are not agencies or public service officers for the purposes of the Public Sector Management Act (s 18(2)), which affects how those WA statutes apply in practice.

Interpretation Act carve‑outs. The Act disapplies the Interpretation Act 1984 to the Rail Safety National Law (WA) (s 20(1)). It further disapplies specific sections of the Interpretation Act in relation to Rail Safety National Regulations (WA) (s 17). Transitional provisions treat prior law repeals and substitutions in a manner consistent with the Interpretation Act but carve out some of its provisions from applying to repeals of subsidiary legislation (s 50).

Courts and tribunals. The Act specifies which WA judicial bodies count as “the court” for different parts of the national Law. This assigns jurisdictional roles to the State Administrative Tribunal and the Magistrates Court for particular parts of the national Law (s 18(1)). That affects appeal and review pathways under the national Law in WA.

Evidence and criminal law interface. Part 3 evidence rules interact with criminal procedure and coronial processes. Section 43 creates statutory evidentiary presumptions for testing conducted under this Part. Section 41 creates authorisation pathways for blood sampling where an injured worker is treated at hospital or where the worker is deceased, including interaction with the Coroners Act 1996 where medical practitioners must report deaths (s 41(2)). Certificates under s 45 bridge administrative records, analyst competency and device operation with court evidence rules, subject to service and attendance safeguards in s 45(2).

Interstate legislative adoption mechanism. The Act imports the South Australian Schedule as at a snapshot date and creates a WA process for later South Australian amending Acts and Regulations to take effect in WA. Amending Acts are laid before WA Parliament and can be disallowed under the WA parliamentary process (ss 7-9). National Regulations made in South Australia after 20 June 2023 must be published on the WA legislation website within 18 days and tabled within six sitting days or they cease to have effect for WA (s 15(2), s 16(1)-(3)). This creates a controlled channel by which interstate legislative activity becomes effective in WA.

Transitional regulations and time limits. The Act permits WA transitional regulations to address gaps between the repealed 2015 Act and the new application model, but limits transitional regulations to two years from commencement day (s 56(4)). Transitional regulations may modify application or provide savings but must not be made after that two year period and cannot have retrospective prejudicial effect against private persons (s 56(4)-(6)).

Administrative and operational interplay. The Act requires certification, authorisation and delegation for device operation and sampling (ss 27, 34, 46). These create operational interdependencies between the Regulator, the Commissioner of Police, hospital staff and analysts under existing WA health and coronial laws. The Act also requires publication and tabling of amending Acts and regulations; failure to comply with those procedural requirements can invalidate the instruments’ effect in WA (ss 7, 15-16).

Repeals and replacement. The Act repeals the Rail Safety National Law (WA) Act 2015 and the Rail Safety National Law (WA) (Alcohol and Drug Testing) Regulations 2015 and Rail Safety National Law (WA) Regulations 2015 (s 48(1)-(2)). It thereby replaces the previous WA application model for the national Law with a new model that imports the South Australian Schedule as at 20 June 2023 and implements a different mechanism for adopting later changes.

Commencement dates. The Act’s Part 1 commenced on Royal Assent, 26 March 2024, while the rest of the Act commenced by proclamation. The compilation table records the Act, other than Part 1, commencing 1 October 2024 (s 2; compilation table). This staged commencement is consistent with the need to effect administrative changes and transitional arrangements.

Snapshot and ongoing adoption. The Act takes a snapshot of the national Law as at 20 June 2023 and explicitly includes the Rail Safety National Law (South Australia) (Fees) Amendment Act 2023 (s 5(1)). For amending Acts enacted in South Australia after 20 June 2023 the Act establishes parliamentary tabling and disallowance mechanisms (ss 7-9). If an amending Act received Royal Assent after 20 June 2023 but before WA’s commencement day, ss 7-9 apply as if the amending Act received Royal Assent on the commencement day (s 10). When an amending Act has effect for WA the Governor must proclaim that fact and fix commencement days for provisions that had come into effect in South Australia prior to the proclamation (s 9).

Regulations adoption and publication. Rail Safety National Regulations made under s 264 of the South Australian Schedule after 20 June 2023 must be published on the WA legislation website no later than 18 days after making (s 15(2)). If made before WA’s commencement day but after 20 June 2023, the same publication timing applies as if made on commencement day (s 15(3)). Regulations must be laid before each House within six sitting days after publication and will cease to have effect if not published, not tabled, or disallowed (s 16).

Transitional provisions and time limits. Transitional regulations may be made to deal with matters not sufficiently covered by the Division 2 transitional provisions (s 56(2)). Transitional regulations are limited to two years after commencement day (s 56(4)). The Act provides that many elements of the former Law flow forward; existing applications for accreditation or registration are taken to have been made under the corresponding provision of the new Law and the Regulator must continue to consider them (s 52). Rights of review and appeal in train immediately before commencement are preserved and to be heard under corresponding new Law provisions (ss 53-55).

Consequential amendments. Part 5 makes consequential amendments to other legislation to align references and to give the Rail Safety National Law (WA) statutory primacy where there is inconsistency with the Government Railways Act 1904 (s 57). Section 58 updates references to the “Rail Safety National Law (WA) Act 2015” across a set of WA Acts.

Evidence and procedural amendment provisions. The Act amends evidentiary and procedural arrangements around alcohol and drug testing, including definitions, device certification, authorised person requirements, and evidentiary certificates (Part 3, ss 21-45). It also excludes WA Acts like FOI and the Auditor General Act from applying to the Law unless applied by the Law itself (s 20).

No judicial history included. The Act contains no reported judicial interpretations or case law because it is newly enacted and the text makes no mention of litigation to date.

No cases are named or described within the text of the Act. The Act contains provisions that preserve and transition ongoing reviews and appeals under the former Law to corresponding provisions of the new Law, indicating legislative anticipation of administrative and judicial proceedings being carried over.

Preservation of existing proceedings. Sections 52-55 are the operative transitional rules for litigation and administrative proceedings. Existing applications for accreditation or registration that were not decided are taken to have been made under the new Law and the Regulator must continue to consider them (s 52). Existing rights of review and appeal that had not expired on commencement day may be exercised under the new Law sections 216 and 217 as if the decisions were made under corresponding provisions of the new Law (ss 53-54). Undecided reviews or appeals before the commencement day must continue to be heard and decided under the corresponding sections of the new Law (s 55). These provisions therefore migrate ongoing litigation and administrative disputes into the new statutory framework without creating procedural nullities.

Evidentiary framework affecting likely litigation. Part 3’s evidence rules will be relevant in future prosecutions, tribunal hearings and coronial inquests. Section 43 creates statutory presumptions regarding blood alcohol content and drug presence in samples taken under this Part. Section 44 bars evidence from improperly conducted or device‑inappropriate tests. Section 45 allows for certificates from those with operational or analytical roles to be admitted as evidence, subject to service and attendance safeguards. Those provisions are likely to shape litigation strategy, disclosure obligations, and admissibility contests in prosecutions and administrative proceedings.

Coronial and post‑mortem directions. Section 41 interfaces with coronial processes by enabling medical practitioners who report deaths under the Coroners Act 1996 to take or request blood sampling for rail safety purposes, and enabling the coroner to direct and authorise a pathologist to take a sample. That creates statutory authority that may be engaged in coronial inquests and related litigation.

No existing reported decisions. The Act does not include a schedule of judicial decisions or indicate any binding precedents specifically interpreting its provisions. Any litigation history will need to be built from future cases applying the Act and the imported national Law as it operates in WA.

Parliamentary instrument challenges. The Act creates parliamentary tabling and disallowance mechanisms for amending Acts and Regulations (ss 7, 15-16). Challenges to the validity or application of adopted amending Acts or national Regulations in WA could arise if procedural tabling or publication requirements were not met. Section 16(2) explicitly causes Regulations to cease to have effect if publication or tabling requirements are not satisfied, which establishes a statutory basis for litigation or judicial review where instruments were not properly published or tabled.

Time window for tests. The Act repeatedly uses a 12 hour threshold as the outer time limit for many compulsory tests. A worker on railway premises after carrying out rail safety work is not obliged to comply with a requirement under the national Law to submit to a preliminary breath test, breath analysis, drug test or blood test if more than 12 hours have passed since the worker finished work and the worker was not involved in a notifiable occurrence (ss 25(1), 32(1), 39(1)). Where the worker was involved in a notifiable occurrence the 12 hour limit applies from the time of the occurrence (ss 25(2)(a), 32(2)(a), 39(2)(a)). The 12 hour window is a strict statutory constraint and can be decisive for whether testing can lawfully be required.

Scope of random testing. The Act permits random testing for both alcohol and drug screening without any reasonable suspicion (ss 24(1)(a), 31(1)(a)). Employers and operators must therefore have policies and procedures that lawfully implement random testing as permitted by the national Law and this Act.

Health and incapacity limits. Authorised persons must not require testing if they suspect, on reasonable grounds, that complying would be detrimental to the worker’s health or that the worker is incapable of providing a sufficient sample because of injury, disability or other reason (ss 26, 33). These are subjective, reasonable‑grounds constraints. Documenting the basis for such suspicions and any medical advice may be important to support compliance with or challenge to a testing requirement.

Device operator and certification rules. Breath analyses and oral fluid analyses must be carried out either by a police officer certified by the Commissioner of Police or by a person authorised by the Regulator to operate the specific device (ss 27(1)-(2), 34(1)-(2)). Using an uncertified operator or non‑authorised device renders the test result inadmissible under s 44. Employers and regulators must ensure authorisations and certifications are current and recorded.

Evidentiary presumptions and limited rebuttal pathways. The Act creates presumptions in s 43 that a breath analysis or blood test taken under this Part indicates the blood alcohol content at the relevant time and that a drug detected in an analysis of oral fluid, urine or blood taken under this Part was present at the relevant time. Rebuttal of breath analysis presumptions is narrowly framed in s 43(3) and largely requires a blood analysis taken under the Part that indicates a contrary result and evidence the breath instrument gave an exaggerated indication. Parties relying solely on peripheral medical or consumption evidence to rebut an instrument reading face a restricted evidentiary route.

Certificate procedural safeguards. Certificates from authorised persons, the Regulator, the Commissioner of Police or hospital staff are admissible as evidence (s 45(1)). However, certificates by the Regulator, authorised persons or hospital staff cannot be used against a defendant unless a copy is served at least seven days before proceedings commence, or the defendant gives two days’ notice to require attendance, or the court orders attendance (s 45(2)). Failure to observe these procedural steps can affect trial preparation and admissibility.

Publication and tabling traps. National Regulations must be published on the WA legislation website within 18 days of being made after 20 June 2023 and laid before each House within six sitting days of publication to take effect as subsidiary legislation (ss 15-16). If these administrative steps are not completed, the Regulations cease to have effect in WA (s 16(2)). That procedural rule can unintentionally nullify regulatory instruments if publication and tabling are overlooked.

Exclusion of WA oversight Acts. Key WA statutes do not apply to the Rail Safety National Law (WA) unless the national Law applies them (s 20(2)). These include FOI, Auditor General and Parliamentary Commissioner frameworks. That may limit the range of oversight and disclosure regimes available for instruments made under the national Law unless the national Law itself imports those mechanisms.

Office classification consequences. The Act specifies that the Office of the National Rail Safety Regulator and its employees are not agencies or public service officers under the Public Sector Management Act (s 18(2)). That classification affects entitlements, disciplinary frameworks and public sector governance rules that would otherwise apply to WA public bodies.

Delegation limits. The Commissioner of Police may delegate certification powers to members at or above Inspector but cannot further delegate those powers (s 46(1), (3)). Delegation must be in writing (s 46(2)). If certification has not been validly delegated, a purportedly certified operator may lack lawful authority to conduct an analysis.

Transitional regulation shelf life. Transitional regulations may be made to address gaps but must be made within two years after commencement day (s 56(4)). Where transitional regulation is necessary, failing to secure it within that two year window could leave regulatory gaps.

Double jeopardy condition. The Act prevents double punishment where the same conduct has already been punished in another participating jurisdiction (s 19). Prosecutors must confirm prior punishments in other jurisdictions to avoid nullified prosecutions.

Interaction with coronial duties. Section 41 enables medical practitioners to take blood samples in hospital contexts and to notify coroners where required. Coroners then have power to authorise pathologists. Practitioners must follow Coroners Act reporting duties to activate these powers.

Governance and policy alignment. Rail transport operators and rail infrastructure managers should update safety management systems and policies to reflect that the national Rail Safety Law, as applied in WA, now governs rail safety obligations (s 5(2)). Policies should explicitly address the testing regimes permitted by Part 3, including procedures for random testing, non‑random testing after notifiable occurrences, and the 12 hour time limits for compulsory testing (ss 24, 31, 25, 32, 39). Operators should ensure their safety management systems document when authorised persons may require tests and how to record the lawful grounds for non‑compliance exemptions (ss 26, 33).

Authorisations, certifications and training. Ensure that persons who will operate breath analysis instruments or oral fluid analysis devices are either police officers certified by the Commissioner of Police or authorised by the Regulator as required by ss 27(1) and 34(1). Maintain written records of certification and Regulator authorisations. The Commissioner of Police may delegate certification in writing to members at or above Inspector (s 46). Train authorised persons in device operation, sampling procedures and the statutory limits on requiring tests so device operation and sample collection comply with the Act and the local regulations to be made under s 47.

Device procurement and maintenance. Use breath analysis instruments and oral fluid analysis devices that satisfy the definitions in s 21(1) and that are authorised under local regulations. Ensure maintenance, calibration and operation records are kept to support certificates that a device was in proper order, as permitted by s 45(1)(d)(ii). Device selection should align with local regulations to be prescribed under s 47 and with national requirements adopted by WA.

Medical and sample taker arrangements. Establish formal arrangements with hospitals, medical practitioners, registered nurses and sample takers to ensure blood samples can be taken where authorised under ss 40-41. Ensure written protocols for dealing with injured or deceased rail safety workers and for obtaining informed consent where feasible, consistent with s 40(2)-(4) and s 41. Sample takers should be familiar with the circumstances in which they are authorised and when they may decline to take a sample as not reasonably practicable.

Evidence management and certificates. Implement chain of custody, sample storage and destruction procedures consistent with local regulations to be made under s 47(2)(b). Where relying on test results for enforcement or disciplinary action, ensure statutory certificate service requirements are met. A certificate by an authorised person or Regulator cannot be used against a defendant without serving a copy at least seven days before proceedings, unless the court orders otherwise (s 45(2)). Prepare to facilitate witness attendance where defendants require the author of a certificate to attend trial.

Operational documentation of reasonable grounds. Where a testing requirement is based on "reasonable grounds" to suspect alcohol or drug impairment (ss 24(1)(b), 31(1)(b), 36(1)(b)), authorised persons should contemporaneously record the facts supporting those grounds to withstand legal scrutiny later. That includes observable conduct, condition or appearance and any steps taken to verify capacity to provide samples.

Respect health and incapacity exemptions. Before enforcing a testing requirement, authorised persons must reasonably consider and document whether compliance would be detrimental to health or whether the worker is incapable of providing a sufficient sample (ss 26, 33). Obtain medical input where necessary and record advice to justify or withdraw a requirement.

Manage timing and shift‑end scenarios. The 12 hour limits are a strict statutory boundary. Ensure shift rosters, incident notification processes and post‑shift communications are aligned so that authorised persons understand when a worker is not obliged to submit to testing because the statutory time period has expired or because the worker had left unaware of a notifiable occurrence (ss 25(2)(b), 32(2)(b), 39(2)(b)).

Monitor parliamentary and publication processes. For any national Regulations or South Australian amending Acts that may affect WA, monitor WA tabling and disallowance processes. Amending Acts must be laid before both Houses within 18 sitting days (s 7) and may be disallowed pursuant to the notice and disallowance periods (s 8). National Regulations must be published on the WA legislation website within 18 days and tabled within six sitting days to take effect (ss 15-16). Failure to track these administrative steps could result in regulatory uncertainty.

Legal and industrial engagement. Consult with unions, employee representatives and legal advisers to ensure that random testing programs and post‑incident testing procedures comply with the Act and with industrial instruments. Consider privacy and workplace rights in light of the evidentiary presumptions in s 43.

Recordkeeping and data retention. Ensure records of tests, analyses, device operation, certificates and chain of custody are retained in line with any local regulations made under s 47 and with the limits on applicability of WA State Records Act noted in s 20(2). Where the State Records Act does not automatically apply to instruments made under the national Law, consider adopting equivalent internal standards for retention and disclosure.

Transitional handling of existing matters. For accreditation, registration, review and appeal matters already underway at commencement, follow the transitional rules in ss 52-55. Treat those matters as carried forward into the new Law and continue to observe existing timelines and procedural rights as implemented under the corresponding new Law sections.

Plan for coronial interaction. Where notifiable occurrences involve injury or death, medical practitioners and hospitals should be ready to act under ss 40-41 and to comply with Coroners Act reporting duties to enable lawful blood sampling and subsequent chain of custody.

Seek specialist legal advice for disputes. Where there is doubt about the lawfulness of a testing requirement, the admissibility of a result, or the applicability of an amending Act or Regulation, obtain legal advice promptly. The Act creates specific procedural traps around device certification, publication and tabling, certificates and evidentiary presumptions that will determine admissibility and enforceability in enforcement or disciplinary proceedings.
