CASA EX78/14 - Repeal of CASA EX53/12 — display of navigation and anti-collision lights

CASA EX78/14 has three main textual concepts running through it: authority, temporal operation, and repeal. Each concept is explicit in the instrument’s short body and forms the legal mechanism by which the instrument achieves its effect.

Authority: The instrument is made "under regulation 11.160 of the Civil Aviation Safety Regulations 1998 and subsection 33 (3) of the Acts Interpretation Act 1901" (preamble). The instrument therefore invokes delegated powers conferred by the Civil Aviation Safety Regulations and an interpretive provision of the Acts Interpretation Act as the legal basis for making the repeal. The person making the instrument is identified as "terence lindsay farquharson, acting Director of Aviation Safety, on behalf of CASA" and the instrument is signed and dated (12 September 2014).

Temporal operation: Clause 1 specifies both commencement and expiry. Clause 1(a) provides a commencement date: "commences on 1 October 2014." Clause 1(b) provides an expiry date: "expires on 2 October 2014, as if it had been repealed by another instrument." That phrasing introduces a particular temporal structure: the instrument is active for a short, defined window and expressly states its expiry will be treated in law in a particular way, namely "as if it had been repealed by another instrument." The text therefore treats the instrument’s own cessation as comparable to repeal by a later instrument, rather than simply lapsing by effluxion of time. The instrument itself does not elaborate on the legal consequences of that form of expiry.

Repeal: Clause 2 contains the operative substantive act: "Instrument CASA EX53/12 is repealed." The meta-information identifies the subject matter of the repealed instrument as the "display of navigation and anti-collision lights." The repeal is stated in absolute terms; there are no accompanying savings, transitional arrangements, or qualifications in EX78/14 itself about continuing obligations, compliance periods, or treatment of past conduct under the repealed instrument.

Taken together, these concepts indicate that EX78/14 is a delegated legislative instrument whose sole purpose is to repeal a named earlier instrument for the period that EX78/14 operates. The short temporal window and the "as if it had been repealed by another instrument" language are unusual textual features that give rise to legal questions about the permanence and timing of effects; the instrument itself does not resolve those questions and contains no further interpretive guidance.

The instrument’s immediate textual effect is to repeal CASA EX53/12. The instrument itself does not set out classes of persons, regulated activities, or rights and obligations that directly change in its own text. Therefore, to identify precisely who is affected in practical terms, it is necessary to look to the repealed instrument (CASA EX53/12), which the present instrument names but does not reproduce. However, the instrument’s text and metadata allow a circumscribed, source-grounded statement about affected parties and decision-makers.

Who decides: The instrument was made by the Acting Director of Aviation Safety "on behalf of CASA" and is signed by Terry Farquharson (preamble and signature). Under the instrument’s stated authority (reg 11.160 of the Civil Aviation Safety Regulations 1998 and subsection 33(3) of the Acts Interpretation Act 1901), the Director/ CASA is the decision-maker for this instrument.

Who is directly affected in legal technique: the named instrument, CASA EX53/12, is the legal instrument being removed. Any persons, organisations or activities that were subject to obligations, permissions, conditions or guidance in CASA EX53/12 are the parties whose legal position was altered by EX78/14. The meta-description links EX53/12 to "display of navigation and anti-collision lights", which indicates that operators, pilots, aircraft owners, maintenance organisations, or other aviation participants who were subject to EX53/12’s provisions (if any) are the relevant groups. EX78/14 itself does not enumerate those classes.

Who bears compliance duties now: EX78/14 contains no new duties or compliance obligations; it only effects repeal. Therefore, the operational compliance burden falls on those who must determine whether the repeal of EX53/12 changes their existing obligations under the wider regulatory framework administered by CASA. That group will typically include operators and pilots whose operational procedures mention navigation or anti-collision light display, compliance officers who maintain manuals and checklists, aviation legal advisers, and CASA enforcement staff who need to interpret which instruments are in force.

Temporal effect on affected parties: because EX78/14 commences on 1 October 2014 and expires on 2 October 2014, the practical window when the repeal has been effected by EX78/14 is textually limited. The instrument does not itself say whether the repeal effected by clause 2 is intended to be permanent or temporary beyond the instrument’s own operation. Therefore, affected parties should note that the timing and permanence of any change to their legal obligations cannot be determined solely from EX78/14’s text; they must consult the repealed instrument, any other instruments or regulations, and the statutory interpretive provisions cited as authority.

Who pays: the instrument does not create fees, fines or recovery mechanisms. Any costs or administrative burdens caused by the repeal (for example, changes to procedures, retraining, or legal advice) would be borne by the entities or persons who need to adjust their procedures to reflect the absence or modification of the content of EX53/12. EX78/14 itself does not allocate costs.

EX78/14 is minimal in normative content. It does not create operative duties or rights in the way that a substantive regulation, standard or exemption might. The instrument’s legal effect is procedural,repeal,and the key "duties and rights" arising from it are therefore indirect and revolve around understanding and responding to that repeal.

Duties of the maker and identification: The instrument identifies the person exercising delegated legislative power: "terence lindsay farquharson, acting Director of Aviation Safety, on behalf of CASA" (preamble). That identifies the administrative actor who has made the instrument under the stated statutory authorities (reg 11.160 CASR; s 33(3) Acts Interpretation Act). The signature and date (signed T. Farquharson; 12 September 2014) record the making of the instrument. Those are the only positive duties described.

Duty-effect via repeal: Clause 2 states simply, "Instrument CASA EX53/12 is repealed." That clause imposes a change upon anyone who previously had duties or rights under EX53/12. In concrete terms, any duty that was created by EX53/12 would cease to have effect to the extent the repeal is operative; any right or permission provided by EX53/12 would likewise be affected. EX78/14 contains no saving clauses protecting acts done under EX53/12 or preserving rights; whether such acts or rights survive repeal must be determined by reference to the broader statutory scheme or to the content of EX53/12 itself. The instrument does not specify whether the repeal extinguishes, suspends or modifies liabilities, or whether there are transitional arrangements.

Rights and procedural protections: EX78/14 contains no express rights, appeal mechanisms or procedural protections for affected persons. The instrument does not provide for compensation, transitional relief or time-limited compliance measures. Any procedural rights (for example, to challenge enforcement action or to seek administrative review) would derive from the general statutory framework, not this instrument.

Temporal qualification of duties and rights: Clause 1(b) states the instrument "expires on 2 October 2014, as if it had been repealed by another instrument." Because the instrument both effects repeal and then indicates its own expiry, a question arises about the continued status of duties and rights formerly created by EX53/12 once EX78/14 has expired. EX78/14 itself does not create express mechanisms to continue or restore duties and rights. Therefore, practitioners must look beyond EX78/14 to determine whether duties under EX53/12 were permanently removed, temporarily suspended, or reinstated by subsequent instruments.

No penalties or compliance mechanisms included: The instrument contains no enforcement or penalty provisions. It does not create reporting duties, inspection powers, certification requirements or compliance timelines. Any enforcement consequences flowing from the repeal of EX53/12 will depend on other instruments and statutory provisions in force in the regulatory environment administered by CASA.

The instrument contains no provisions establishing offences, penalties, enforcement powers, or compliance procedures. Its operative text is limited to repeal and to specifying commencement and expiry dates; there is no penalty or enforcement language in either the preamble or the two clauses.

What the instrument does not do: EX78/14 does not create new enforcement powers for CASA, does not impose monetary penalties, does not prescribe compliance procedures, and does not specify a mechanism by which any earlier breaches under CASA EX53/12 would be dealt with. It does not provide criminal or civil sanctioning mechanisms nor does it identify administrative enforcement steps to be taken in response to non-compliance. As a consequence, the instrument itself is not an enforcement tool.

Indirect enforcement implications: Repeal of an instrument can change the enforcement landscape by removing a statutory or administrative basis that enforcement actions rely on. Clause 2's repeal of CASA EX53/12 therefore may remove a legal basis previously used to enforce requirements related to the "display of navigation and anti-collision lights" (as the meta-description indicates). EX78/14 contains no transitional or savings clause preserving existing enforcement standing; therefore, whether CASA (or another regulator) can continue to enforce conduct that previously contravened EX53/12 depends on the existence of other instruments, regulations, or statutory provisions that maintain equivalent or overlapping obligations. EX78/14 does not address or secure that continuity.

No express retrospective effect: The instrument does not state that repeal has retrospective effect or that it affects liability for conduct that occurred before the commencement of EX78/14. Absent such language, and given that the instrument itself does not create new offences, any questions about retrospective liability would need to be resolved by reference to the broader statutory and regulatory framework and to the text of EX53/12.

Enforcement after expiry of EX78/14: The instrument itself expires on 2 October 2014 "as if it had been repealed by another instrument." EX78/14 does not say whether the repeal effected by clause 2 remains in force after EX78/14 expires. From an enforcement perspective, this absence of clarity means that practitioners and enforcement officers cannot deduce enforcement reach from EX78/14 alone; they must check the register of instruments and any succeeding instruments to determine which obligations are enforceable at a given time.

EX78/14 is explicitly made under two statutory references and interacts directly with a previously made CASA instrument. The instrument therefore sits within a network of delegated legislation and interpretive statute. The text identifies those interactions but does not elaborate them.

Statutory making power: The instrument’s preamble cites regulation 11.160 of the Civil Aviation Safety Regulations 1998 and subsection 33(3) of the Acts Interpretation Act 1901 as the bases for making the instrument. That identifies the delegated legislative power and an interpretive provision relied upon for procedural or interpretive effect. The instrument itself does not reproduce those provisions nor does it explain how they operate; the text therefore presupposes that the instrument will be read and applied against the background of those statutory provisions.

Interaction with the repealed instrument: Clause 2 states "Instrument CASA EX53/12 is repealed." The repealed instrument (EX53/12) is the immediate nexus for interaction. Any statutory obligations, permissions, exemptions, or directions contained in EX53/12 cease to operate to the extent the repeal takes effect. Because EX78/14 does not include savings or transitional provisions, the legal status of acts taken under EX53/12, or of continuing obligations, is not resolved within EX78/14 and must be determined by examining EX53/12, the Civil Aviation Safety Regulations, and any other instruments that touch the field.

Temporal interaction through expiry language: Clause 1(b) adds a peculiar phrase: EX78/14 "expires on 2 October 2014, as if it had been repealed by another instrument." That wording invites attention to how expiry and repeal interact under the Acts Interpretation Act and the regulatory scheme. If an instrument that effects repeal itself expires "as if it had been repealed," questions arise about whether the repeal it declared persists after the repealing instrument ceases. The instrument does not itself answer that question; resolution requires reference to the interpretive rules in the Acts Interpretation Act and to any relevant transitional or saving rules in the Civil Aviation Safety Regulations or in the repealed instrument.

No express savings or transitional provisions: EX78/14 contains no clauses preserving acts done under EX53/12, no preservation of licenses or approvals, and no statement about the effect on offences or liabilities that arose under EX53/12. Therefore, interactions with other laws governing liability, contracts, administrative decisions, and enforcement are left to be resolved by operation of general statutory rules, other instruments, or judicial interpretation. The instrument itself does not provide cross-references or carve-outs.

Administrative record-keeping and registry interaction: Because the instrument amends (by repeal) the delegated-instrument register, it interacts with administrative processes such as gazettal, legislative registers, and CASA’s internal instrument records. EX78/14 does not specify publication steps beyond its own text, so anyone relying on it should verify physical or online instrument registers to ensure that the repeal has been recorded and to determine the precise legal position across dates.

The instrument contains internal dating and a short life cycle but, on its face, shows no sequence of amendments or revisions. The text itself records a single making and an intention for very limited temporal operation. The instrument’s explicit historical data points are the only things available in its text.

Making date and signatory: The instrument was made on 12 September 2014 and is signed by Terry Farquharson, Acting Director of Aviation Safety. That is the primary chronological marker in the instrument and identifies the authority responsible for its creation.

Commencement and expiry: Clause 1 establishes the effective operational dates: commencement 1 October 2014 (cl 1(a)) and expiry on 2 October 2014 (cl 1(b)). The expiry is qualified by the phrase "as if it had been repealed by another instrument." Those dates constitute the entirety of the instrument’s intended temporal operation as recorded in the instrument.

No recorded amendments in the instrument text: The instrument does not contain any schedules of amendments, nor does it indicate that it amends other instruments except for the explicit repeal in clause 2. There are no subsequent amendment dates or variant versions in the text supplied.

No amendment power invoked to alter the instrument itself: The instrument does not provide for amending or varying itself; it simply sets an expiry date. There is no repository of further changes in the instrument text.

Implication for legislative history research: From the text alone, the legislative history of EX78/14 consists of the single acting decision recorded on 12 September 2014 and its short operational period between 1 and 2 October 2014. Any fuller amendment history beyond that , for example, whether EX78/14 was superseded by another instrument, whether EX53/12 was later remade, or whether other instruments affected the same subject , cannot be discerned from EX78/14 itself and requires consulting instrument registers, gazettes or CASA administrative records. The instrument’s metadata and title identify the subject of the repealed instrument ("display of navigation and anti-collision lights") but do not record whether other instruments altered that subject before or after EX78/14.

EX78/14 contains no internal references to litigation, and the instrument text does not record any court or tribunal proceedings related to its making, validity, or effects. The instrument’s own text does not mention judicial review, appeal rights, or any litigation arising from its adoption.

Absence of litigation notes: Because EX78/14 is a two-clause instrument with a one-day effective window, the text does not include or purport to summarise any disputes, challenges or decisions. It does not cite case law and does not indicate whether any legal challenges were contemplated at the time of making.

What can be concluded from the text: The instrument itself does not evidence any litigation history. Any litigation connected to the repeal of CASA EX53/12, to the subject matter of navigation and anti-collision lights, or to the validity of delegation under reg 11.160 or subsection 33(3) of the Acts Interpretation Act is not recorded in EX78/14 and therefore cannot be reported from this instrument alone. To establish whether any litigation has arisen in relation to EX78/14 or the instruments it affects, one must consult court records, tribunal databases, or summaries provided by CASA and other official repositories.

Practical note for litigators and advisers: Because EX78/14 effects repeal but provides no transitional language, potential litigation questions could include whether the repeal produced unintended gaps in regulation, whether enforcement actions relying on EX53/12 were properly discontinued or preserved by other law, and whether the short lifespan of EX78/14 produced any legitimate expectation or administrative law issues. None of those matters, however, are addressed in EX78/14 itself; they would have to be established from external facts and legal records beyond this instrument.

The instrument’s brevity and precise wording create a number of concrete legal and practical traps for practitioners who rely on it without checking the full statutory and administrative context. The following points are grounded in the instrument’s text and flag where further investigation is necessary.

Short, explicit life-span: EX78/14 "commences on 1 October 2014" and "expires on 2 October 2014" (cl 1). That one-day operational span is unusual. Practitioners who assume the repeal is permanent without checking whether subsequent instruments replaced or re-enacted the relevant provisions risk relying on an incorrect regulatory position. The instrument does not say whether the repeal persisted after its expiry.

Expiry phrased "as if it had been repealed by another instrument": Clause 1(b) adds that the expiry is "as if it had been repealed by another instrument." That phrase raises uncertainty as to whether the legal effect of the repeal persists, is conditional, or is time-limited in a manner different from ordinary expiry. This language requires attention to the interpretive provisions that the preamble invokes (not reproduced in the instrument), because the instrument itself gives no explanation.

No savings, transitional or retrospective language: Clause 2 simply states "Instrument CASA EX53/12 is repealed." The instrument contains no clause preserving acts done in reliance on EX53/12, no explicit protection for licences, approvals or applications made under EX53/12, and no guidance about liability for past conduct. Failure to verify whether such saving provisions exist elsewhere may produce compliance or enforcement problems.

Lack of substantive content in the repealing instrument: EX78/14 does not set out the content of EX53/12. The meta-description indicates the subject matter of EX53/12 ("display of navigation and anti-collision lights"), but EX78/14 does not include any substantive regulation or guidance concerning that subject. Practitioners cannot infer from EX78/14 what the practical consequences are without consulting EX53/12 and any related instruments.

No penalties or enforcement language: Because EX78/14 contains no enforcement or penalty clauses, it neither prescribes nor removes enforcement mechanisms explicitly. The practical enforcement consequences of the repeal therefore hinge on the presence or absence of other instruments or statutory provisions. Assuming that enforcement is unchanged without checking those instruments is a pitfall.

Reliance on instrument registers: The instrument does not describe publication steps or administrative recording beyond its text. To confirm the legal effect of the repeal at any given date, users must consult the official Commonwealth or CASA instrument registers and the Government Gazette, rather than rely solely on the text of EX78/14.

Who bears the compliance cost: EX78/14 does not explicitly allocate costs. Any costs resulting from the repeal (for example, updating manuals, retraining, or legal advice) are borne by regulated entities unless another instrument or agency provides relief. Assuming any taxpayer-funded remediation or transitional support will be provided is not supported by EX78/14’s text.

Actionability of the repeal: Because EX78/14 expires the day after it commences, there is a potential administrative "gap" between the repeal and any replacement regulation. Practitioners should be wary of assuming continuous regulation; the instrument itself does not indicate whether continuity was intended or achieved by other means.

EX78/14 itself imposes no affirmative compliance steps beyond observing its commencement and expiry and recognising that it repeals CASA EX53/12. Compliance in practice therefore consists of confirming the practical legal position arising from the repeal and taking proportionate administrative steps. The actions below are grounded in the instrument’s text and are practical next steps for operators, compliance teams, legal advisers and CASA staff.

1. Verify the instrument and dates in official registers.

   • Confirm the text, the commencement date "1 October 2014" and the expiry date "2 October 2014" in the official instrument register and Government Gazette (the instrument records those dates in clause 1).
   • Ensure the signed version and any administrative notes on gazettal are obtained, because the instrument’s short lifecycle makes accurate record-keeping essential.

2. Retrieve and review CASA EX53/12 (the repealed instrument).

   • Clause 2 repeals "Instrument CASA EX53/12." To assess what duties, permissions or conditions have been removed, review the full text of EX53/12 and extract the specific obligations that applied to your operations. EX78/14 contains no substantive content about the subject matter, so EX53/12 is essential to understanding the legal change.

3. Assess temporal effect and continuity.

   • Note EX78/14’s unusual expiry wording: it "expires on 2 October 2014, as if it had been repealed by another instrument" (cl 1(b)). Check whether a successor instrument was made, whether EX53/12 was subsequently re-issued, or whether other regulations preserve necessary obligations. Do not assume permanence of the repeal on the basis of EX78/14 alone.

4. Update compliance manuals and operational procedures where required.

   • If EX53/12 created specific obligations for display of navigation and anti-collision lights that have been removed and are not replaced elsewhere, update manuals, checklists and SOPs to reflect the current statutory position. Conversely, if other instruments continue to impose equivalent requirements, document that continuity.

5. Document reliance and past compliance actions.

   • Keep records of actions taken under EX53/12 to demonstrate compliance history. Because EX78/14 contains no savings clauses, preserving records of compliance or approvals obtained under EX53/12 may be important in responding to queries or enforcement actions.

6. Seek legal advice where ambiguity exists.

   • If the commercial or safety implications of the repeal are material, obtain legal advice to determine whether obligations remain under other instruments, regulations or general safety obligations administered by CASA. EX78/14’s brevity and the expiry phrase create interpretive questions that may warrant legal analysis.

7. Liaise with CASA or the Responsible Authority.

   • For operational uncertainty,particularly on safety-critical matters like navigation and anti-collision lights,seek clarification from CASA. The instrument was made by the Acting Director of Aviation Safety on behalf of CASA; direct engagement can confirm whether the repeal was intended to be temporary, to clear an inconsistency, or to be replaced by another instrument.

8. Monitor for subsequent instruments and policy statements.

   • Because EX78/14 itself expires quickly, monitor for replacement instruments, amendments to the Civil Aviation Safety Regulations, or CASA advisory material that confirm the ongoing regulatory position for navigation and anti-collision lights.

9. Preserve chain-of-authority documentation.

   • Keep a record of the making authority cited in the preamble (reg 11.160 CASR; s 33(3) Acts Interpretation Act), the signature and date, and the instrument number (CASA EX78/14) so that reviewers can trace the legislative chain. This is particularly important for auditing and legal defensibility.

10. Treat safety obligations independent of instrument status.

• The instrument addresses an administrative legal instrument; safety obligations under broader aviation law or operational risk management may persist regardless of the status of EX53/12. Ensure that safety practices remain sound and that any regulatory change does not inadvertently reduce adherence to established safety standards unless a considered, documented replacement is in place.

Following these steps will not, and cannot, be completed on the basis of EX78/14 alone because the repealed instrument’s content and any successor instruments determine the substantive compliance position. EX78/14’s text provides the trigger for these steps , the repeal and the dates , but practitioners must consult the sources that contain the actual operational requirements.
