Supreme Court Act 1933

The Act directly regulates and binds a wide cohort of actors within and interacting with the ACT justice system. At the apex are the judicial officers: the Chief Justice, resident judges (appointed by the Executive under s 4 with statutory eligibility criteria excluding those over 70 (s 4(2)(b)), additional judges from Commonwealth or State superior courts (s 4A), and acting judges limited to two-year terms (s 4B(2)). These office-holders are subject to seniority rules (s 5), oath or affirmation requirements (s 19 and schedule 1), restrictions on other offices or remunerative employment without Executive approval (s 16), and specific remuneration linkages to Federal Court entitlements with Territory modifications (Part 2B, especially s 37U and s 37UA). Former judges may complete part-heard proceedings without further remuneration (s 60A).

Court officers are also centrally affected. The Attorney-General appoints the registrar (s 46(1)), who administers oaths, exercises rule-based jurisdiction, and maintains transcripts (ss 47, 74A). The director-general appoints the sheriff (s 46(2)), responsible for process execution, custody, and returns (s 50), with powers to appoint deputies and public servant assistants who inherit the sheriff's immunities (ss 51–53). Deputy registrars share registrar functions (s 47(2)–(3)). Special rules apply where the sheriff or deputy is a party (s 52).

Legal practitioners are regulated in admission and practising certificate proceedings, which must generally be heard by a Full Court (s 11), and in their role advising clients on judge-alone elections (s 68B(1)(b)). The Act binds parties to proceedings—plaintiffs, defendants, accused persons, appellants, and interested parties in reference appeals (s 37S(4))—through its procedural, evidentiary, and jurisdictional rules. This includes vexatious litigants subject to declarations, stays, and leave requirements (s 67A), offenders subject to drug and alcohol treatment orders and case conferences (Part 2AA), and acquitted persons facing potential retrial applications (Parts 8AA and 8AB).

The Executive, Attorney-General, Solicitor-General, and Director of Public Prosecutions exercise appointment, application, and prosecution powers (ss 4, 4A, 4B, 37S, 68M–68O, 68Q–68V). The Territory itself is affected through appropriations for judicial remuneration and indemnities (s 37X, s 37UA), publication restrictions enforceable as contempt (s 68Z(6)), and costs indemnification orders (s 68ZB).

Indirectly, the legislation affects the broader ACT community by governing the administration of justice, including habeas corpus and prerogative relief (s 34B), change of venue (s 63), and final determination of all matters in issue to avoid multiplicity (s 32). It intersects with victims, witnesses (s 58A), and sureties (s 70A). Because the dictionary and notes apply Territory-wide unless displaced (s 2, s 2A, Legislation Act 2001 ss 155–156), any person or body engaging the Supreme Court—whether in civil, criminal, appellate, or therapeutic jurisdiction—falls within its reach.

Judges owe duties of office including taking the prescribed oath or affirmation before exercising functions (s 19), observing seniority and recusal rules (s 5, s 37H(3)), and ensuring orderly business under the Chief Justice's arrangements (s 7). They must, so far as practicable, finally determine all matters in issue and avoid multiplicity of proceedings (s 32(1)), granting legal or equitable relief absolutely or conditionally as needed (s 32(2)). In judge-alone criminal trials, judges must record principles of law and findings of fact (s 68C(2)) and take account of any jury warnings or directions required by Territory law (s 68C(3)). Court of Appeal judges deliver reserved judgments even if not all are present (s 37M) and may receive further evidence by oral examination, affidavit, or audiovisual link (s 37N(3)).

The registrar must administer oaths (s 47(1)), exercise delegated jurisdiction (s 8(2)–(3), s 10), maintain custody of records, and certify transcripts (s 74A). The sheriff is under a statutory duty to serve or execute process, make due return, take charge of persons committed to custody, and discharge them as directed or required by law (s 50). Deputies and assistants inherit these duties and corresponding immunities (ss 51, 53).

Accused persons in criminal proceedings have the right to elect judge-alone trial for non-excluded offences, subject to written election, independent legal advice certificate, filing before knowing the trial judge, and unanimity where multiple accused are involved (s 68B(1)). They may withdraw an election before arraignment but not reinstate it (s 68B(2)–(3)). In acquittal retrial applications, acquitted persons are entitled to appear and be represented (ss 68M(4), 68N(5), 68O(3)), to bail under the Bail Act 1992 s 9A (s 68X), and to costs indemnification where the interests of justice so require (s 68ZB). Publication identifying them is restricted until proceedings conclude or no further step is possible (s 68Z), with breach punishable as contempt.

Plaintiffs and defendants enjoy concurrent law and equity rights mirroring pre-Judicature Act positions (ss 26–29, 33), with entitlement to equitable damages (s 34) and stays in lieu of injunctive relief (s 30). Vexatious litigants may apply without leave to vary or revoke declarations (s 67A(11)). Parties to appeals receive broad remedial rights: the Court of Appeal may make any order it considers appropriate, even beyond the notice of appeal and in favour of non-appellants (s 37O(5)–(6)), and may order new trials on conditions, admissions, or use of prior testimony (s 37P).

The Director of Public Prosecutions holds statutory rights to apply for retrial orders (ss 68M–68O), present indictments within strict time limits (ss 68U–68V), and conduct reference appeals (s 37S), but is prohibited from referring certain matters to the jury on retrial (s 68W). The Attorney-General may prosecute by information (s 68(1)), decline to proceed (s 68(6)), or apply for reference appeals (s 37S(2)).

Treatment order judges may convene case conferences and give directions necessary to achieve order objectives (s 37SD), while the court as a whole is not bound by evidence rules in that jurisdiction (s 37SC). All participants benefit from the court's obligation to avoid multiplicity and achieve finality (s 32).

The Act itself contains relatively few direct offence-creating provisions, instead relying on contempt, regulatory, and cross-referenced penalties. Failure to attend as required by recognisance or subpoena attracts a warrant for arrest (s 70A(1)) and, if without just cause, a fine not exceeding $5,000, imprisonment up to six months, or both (s 70A(2)). Contravention of vexatious litigant restrictions is taken to permanently stay the proceedings, with documents returnable (s 67A(9)–(10)), while the declaration itself is enforceable as a notifiable instrument (s 67A(8)).

Breach of publication restrictions under s 68Z is punishable as contempt of the Supreme Court (s 68Z(6)). Contempt proceedings are therefore the primary enforcement vehicle for many procedural breaches.

Enforcement of court orders occurs through the sheriff's statutory duties (s 50), with the Court of Appeal able to enforce its own orders or remit for single-judge enforcement (s 37O(1)(f)). Judgments may be executed as if they were the single judge's own (s 37O(4)). The registrar's custody of records and certification of transcripts (s 74A) supports enforcement in subsequent proceedings, where certified transcripts are admissible to the same extent as oral evidence if the witness is unavailable for prescribed reasons (s 74A(7)).

Penalties for offences dealt with as backup or related matters mirror Magistrates Court sentencing powers (s 68E(3)). In retrial scenarios, the maximum penalty cannot exceed that applicable at the time of the original alleged conduct (s 68ZA). Costs indemnification orders under s 68ZB are enforceable against Territory funds once assessed as reasonably incurred.

Judicial officers are subject to removal or suspension mechanisms referenced via modified application of Commonwealth judges' legislation (s 37U(4)(f)), while acting judges serve on Executive-determined conditions (s 37V). Vexatious litigant declarations may be varied or revoked by the court (s 67A(7)), with conditions including security for costs (s 67A(5)).

The penalty unit values at republication are $160 for individuals and $810 for corporations (per Legislation Act 2001 s 133), though most sanctions in the Act are expressed in fixed dollar or imprisonment terms or as contempt.

The Act is not freestanding; it operates within a dense web of Territory and Commonwealth legislation. The Legislation Act 2001 supplies dictionary definitions, notifiable instrument status, editorial change powers, and rules on notes (ss 2, 2A). It also governs penalty units, commencement, and republication (endnotes reference Legislation Act 2001 pts 11.3, ss 115, 117, 133, 155–156, 169).

Criminal jurisdiction interacts closely with the Crimes Act 1900 (schedule 2 lists excluded offences by provision, e.g. murder under s 12, sexual assaults under ss 51–55), the Criminal Code (administration of justice offences in Part 8AA), and the Crimes (Sentencing) Act 2005 (drug and alcohol treatment orders under s 12A, outstanding offences under s 57, non-conviction orders under s 17). Backup and related offence provisions cross-reference Magistrates Court Act 1930 committal and summary jurisdiction powers (s 68D(1), s 68CA).

Appellate and acquittal provisions (Parts 8AA, 8AB) abrogate common-law double jeopardy rules to the extent necessary (s 68H(3)), interacting with the Bail Act 1992 (s 68X) and Evidence (Miscellaneous Provisions) Act 1991 (audiovisual and audio links in ss 37N, 55A). Legal profession matters reference the Legal Profession Act 2006 (s 11).

Judicial remuneration imports, with modifications, the Judges’ Pensions Act 1968 (Cth) and Judges (Long Leave Payments) Act 1979 (Cth) as if Territory laws (s 37U(4)), including changes to marital relationship definitions and references to ACAT instead of the Commonwealth Administrative Appeals Tribunal. Superannuation surcharge indemnity references the Superannuation Contributions Tax (Assessment and Collection) Act 1997 (Cth) (s 37UA(4)).

Court Procedures Act 2004 supplies the rules that delegate jurisdiction to the registrar (s 8(2)) and govern forms and practice. The Judicial Commissions Act 1994 is referenced for removal purposes (s 37U(4)(f)).

The Act preserves pre-Judicature Act 1873 (UK) equitable positions (ss 26–30, dictionary definition of “pre-Judicature Act proceedings”) while applying them in the Territory context. It interacts with the Electoral Act 1992 by prohibiting appeals from the Court of Disputed Elections (s 37E(3)).

Transitional provisions (Part 13) address the shift from “Master” to “associate judge” terminology and its abolition, preserving certain appeal and completion powers. Judicial exchange (Part 8A) operates by reference to schedule 3 corresponding courts and participating jurisdictions, excluding federal courts (s 69B(2)).

In all cases, the dictionary definitions apply unless context or express provision displaces them (s 2, Legislation Act 2001 s 155), ensuring seamless integration.

The republication effective 26 November 2025 incorporates amendments by A2025-29 (Statute Law Amendment Act 2025), which made technical statute law revision changes under the Legislation Act 2001 Part 11.3 editorial powers. These are formal, non-substantive adjustments to bring the text into line with current drafting practice (see endnote 1 and the “About this republication” section).

More substantively, the Courts Legislation Amendment Act 2023 (A2023-37) abolished the associate judge (formerly Master) office, necessitating transitional provisions now in Part 13 (ss 119–123, expiring 30 September 2027). These preserve equal-division rules, interlocutory appeal requirements, and completion powers for pre-abolition matters. The change streamlined judicial hierarchy and aligned the ACT with other jurisdictions, removing an intermediate tier that had become anomalous after the 2015 introduction of the Court of Appeal.

The Supreme Court Amendment Act 2023 (A2023-48) introduced Part 8AB, creating a statutory right for convicted persons to seek leave to appeal on fresh and compelling evidence (s 68ZG), with corresponding definitional and procedural rules (ss 68ZC–68ZH). This mirrored and complemented the prosecution-initiated retrial regime in Part 8AA, responding to recommendations from royal commissions and law reform bodies to correct miscarriages of justice where new reliable, substantial, and highly probative evidence emerges post-conviction. It applies to convictions before or after commencement (s 68ZC(2)).

The Sentencing (Drug and Alcohol Treatment Orders) Legislation Amendment Act 2019 (A2019-31) inserted Part 2AA, conferring explicit jurisdiction over treatment orders, non-binding evidence rules, and case-conferencing powers. This supported the therapeutic justice model introduced in the Crimes (Sentencing) Act 2005, aiming to reduce recidivism among substance-dependent offenders by integrating judicial supervision with clinical teams.

The Justice and Community Safety Legislation Amendment Act 2023 (No 3) (A2023-57) refined vexatious litigant provisions (s 67A), clarifying single-course-of-action rules and notifiable instrument status.

These amendments reflect ongoing modernisation: enhancing finality and correctness of verdicts (Parts 8AA/8AB), therapeutic sentencing options (Part 2AA), judicial efficiency (abolition of associate judge), and protection against process abuse (s 67A). They respond to practical court experience, law reform reports, and alignment with national standards on double jeopardy exceptions and judicial mobility.

Although the Act does not itself generate a large body of reported challenges to its own validity—being largely procedural and constitutive—its provisions have been tested in several notable ways. The Court of Appeal's composition and decision-making rules (ss 37H–37L) have been considered in cases where a judge becomes unavailable mid-appeal, with the statutory continuation and rehearing mechanisms upheld as practical accommodations that do not offend natural justice provided parties consent or rehearing occurs.

The judge-alone election regime (s 68B) has attracted argument concerning the timing and certification requirements. Courts have strictly enforced the pre-knowledge-of-judge and legal advice certificate preconditions, rejecting late or uncertified elections to preserve the statutory safeguards against perceived judge-shopping. Challenges asserting incompatibility with jury trial rights under common law or human rights legislation have generally failed, the Act being clear that jury trial remains the default except for excluded offences listed in schedule 2.

Acquittals provisions (Part 8AA) have been controversial since introduction in 2016. Defence submissions that “fresh and compelling” evidence thresholds (s 68K) or “interests of justice” tests (s 68P) are insufficiently protective of finality have been rejected, the Court emphasising the high bar of reliability, substantiality, and high probative value, plus explicit consideration of fair trial prospects and prosecutorial diligence. Publication restrictions (s 68Z) have generated interlocutory contempt applications, with courts balancing open justice against the statutory prohibition until proceedings conclude.

The vexatious litigant power (s 67A) has been invoked in protracted civil litigation, with challenges focusing on the breadth of “frequently instituted vexatious proceedings” and the permanent stay effect. Courts have construed the section consistently with its protective purpose, confirming that declarations may be varied or revoked and that unrepresented applicants retain the right to seek such variation without leave (s 67A(11)).

Remuneration and pension provisions (Part 2B, especially the modified application of Commonwealth judges’ legislation in s 37U) have been examined in superannuation surcharge and domestic partner recognition cases. The Territory’s indemnity obligation (s 37UA) has been upheld as a valid appropriation of public money.

Procedural provisions such as s 60A (former judges completing part-heard matters) and s 37O (appeal powers) have been challenged on separation-of-powers or due-process grounds but sustained on the basis that they are incidental to the judicial power conferred by s 20 and do not impair institutional integrity.

Controversies have also arisen around the interaction with human rights legislation, particularly publication bans and retrial rights, but the Act’s explicit abrogation of double jeopardy “however expressed” (s 68H(3)) has been held to prevail subject to the detailed safeguards provided.

No challenge has successfully impugned the core constitution of the court under s 3 or the breadth of jurisdiction in s 20, which courts have read as conferring plenary power consistent with a superior court of record.

Most practitioners appreciate the headline jurisdiction and appeal rules, but several subtle traps recur. First, the judge-alone election under s 68B is unforgiving: the legal practitioner certificate must confirm advice and free election, and filing must precede any knowledge of the trial judge’s identity. A single inadvertent disclosure or late filing invalidates the election, with no reinstatement possible once withdrawn (s 68B(3)). Schedule 2’s excluded offences are broader than many realise, capturing not only murder and sexual assaults but also specific industrial manslaughter and radiation-safety offences causing death.

Second, Part 8AA retrial applications appear prosecution-friendly yet contain hidden limitations: only one retrial application per acquittal (s 68R(1)), strict 28-day post-charge or warrant time limits (extendable but requiring justification under s 68Q), and mandatory charging or warrant before application (s 68Q(1)). The “interests of justice” test (s 68P) expressly includes police/prosecutorial diligence, creating a tactical opportunity for defence to adduce evidence of delay that can defeat even compelling fresh evidence.

Third, s 37O(3) contains the “no substantial miscarriage of justice” proviso that allows the Court of Appeal to dismiss an otherwise meritorious conviction appeal. This is narrower than the common-form proviso in other jurisdictions; many advocates overlook that it operates only after the court has already formed the view that the appeal point might be decided in the appellant’s favour. The interplay with s 37O(2)(a)(iii) (any ground involving miscarriage) requires careful forensic judgment.

Fourth, treatment order jurisdiction (Part 2AA) is deceptively informal. Although the court is not bound by evidence rules (s 37SC), case conferences under s 37SD can occur without the offender or lawyer present unless the court directs otherwise. Admissions or concessions made in such conferences can later influence cancellation or amendment decisions, yet the absence of formal evidentiary safeguards surprises those expecting traditional adversarial protections.

Fifth, the vexatious litigant regime (s 67A) applies to “proceedings” defined extraordinarily broadly to include any matter in any court or tribunal. A declaration limited to a particular type of matter still stays all pending proceedings of that type (s 67A(3)(b)), and contravention automatically stays fresh proceedings permanently (s 67A(9)). The power to impose security-for-costs conditions (s 67A(5)(a)) can be used strategically to sterilise further litigation even if leave is granted.

Sixth, remuneration linkage in s 37U incorporates Commonwealth judges’ pension legislation with same-sex and domestic-partner extensions, but the “appropriate current judicial salary” for abolished offices is determined by ministerial notifiable instrument (s 37U(5)(c)), creating potential for administrative challenge if the determination is not made or is unreasonable.

Seventh, s 60A allows former judges to finish part-heard matters but expressly disentitles them to further remuneration or entitlements. This interacts with acting judge appointments (s 4B) and can catch parties unaware when a judge retires mid-hearing, potentially requiring consent to continue before two judges under s 37L.

Finally, the publication prohibition in s 68Z survives until the earliest of “no further step possible” or trial conclusion, yet is subject to court variation. Media organisations frequently miscalculate the duration, exposing themselves to contempt despite the statutory defence of court authorisation.

These nuances reward close reading of the statute and dictionary rather than reliance on general superior-court assumptions.

Compliance begins with institutional actors. The Executive must determine and notifiy selection criteria and processes for resident judges (s 4AA(2)), consult the Chief Justice before approving additional offices (s 16(3)), and ensure appropriations for entitlements (s 37X). Appointments of registrar and sheriff must follow Legislation Act 2001 Part 19.3, with public servant status for deputies and assistants (s 46).

Judges must take the schedule 1 oath or affirmation before acting (s 19), observe recusal on their own prior orders (s 37H(3)), and deliver timely reserved judgments (s 37M, s 61). In judge-alone trials they must produce reasoned judgments containing legal principles and factual findings (s 68C(2)). Treatment order judges should document directions given at case conferences (s 37SD).

The registrar must maintain accurate records, certify transcripts (s 74A), and exercise delegated jurisdiction only within rule limits (s 10). The sheriff must execute all directed process, maintain custody, and appoint only public servants as assistants (ss 50, 53).

Legal practitioners advising on judge-alone elections must provide independent advice and sign the statutory certificate (s 68B(1)(b)); failure can invalidate the election and expose the practitioner to professional conduct complaints. When acting for acquitted persons in retrial applications, practitioners should scrutinise whether the 28-day limit has been met, whether evidence meets the tripartite “fresh, compelling, and interests of justice” test, and whether costs indemnification should be sought (s 68ZB).

Parties and their lawyers must file judge-alone elections before knowing the trial judge (s 68B(1)(c)(i)) and ensure all co-accused elect and are not charged with schedule 2 offences. In appeals, grounds must be carefully framed because the Court of Appeal may make orders beyond those sought and in favour of non-appellants (s 37O(5)). Vexatious litigants must obtain leave before instituting fresh proceedings and may wish to pre-emptively seek variation of any conditions (s 67A(4), (11)).

Prosecutors must not mention the Court of Appeal’s preliminary findings on fresh evidence or tainted acquittal when addressing the retrial jury (s 68W), and must present fresh indictments within two months of retrial order or seek leave demonstrating expedition and no injustice (ss 68U–68V). Publication of identifying material is prohibited until statutory sunset (s 68Z(4)); applications for authorisation should be made promptly.

Court users seeking prerogative relief should plead under s 34B rather than historical writ forms. Those subject to drug treatment orders must understand that non-compliance can lead to cancellation after case-conference input, even if evidence would be inadmissible in ordinary proceedings.

To avoid inadvertent breach, all users should consult the dictionary (which imports Legislation Act 2001 definitions) and cross-referenced statutes. Regular training on Parts 8AA and 8AB is advisable given their procedural complexity and severe consequences of non-compliance with time limits or publication bans. Finally, because the Act is frequently amended by statute-law revision and justice-sector packages, practitioners must check the latest republication and endnotes for uncommenced provisions or modifications (symbols U and M).

Systematic file checklists referencing key sections (appointment validity, election timing, evidence freshness, publication clearances) materially reduce risk and ensure the court’s statutory objectives of finality, efficiency, and justice are met.
