Guardianship and Administration Act 1990

The Act primarily affects adults (18+) with "mental disability" impairing capacity to manage personal health/safety, make reasonable personal judgments, or handle financial affairs (ss.43, 64). "Represented persons" are those subject to guardianship or administration orders (s.3(1)). It extends to those approaching 18 where future need is established (s.43(2a)-(2c)).

Guardians, administrators, enduring guardians, donees of enduring powers of attorney, makers of advance health directives, and "persons responsible" (spouses, relatives, carers under s.110ZD(3)) are directly regulated. The Public Advocate, SAT members, health professionals, researchers, and HRECs bear statutory duties. Nearest relatives (defined hierarchically in s.3(1)) receive notice and standing (ss.41, 60, 89, 110ZNC).

Interstate arrangements (ss.44A, 83A-83D) affect persons moving between jurisdictions with reciprocal orders. Medical research provisions impact "research candidates" (s.3(1)), lead researchers, and independent medical practitioners (s.110ZO). Abortion-related rules (added 2023) specifically engage women/girls over 18 unable to judge abortion decisions (s.110ZLA), health professionals (s.110ZLB), and the Public Advocate.

Family members, supportive relationships, and cultural communities are indirectly affected through s.4(7) and best interests tests (ss.51, 70). The Act does not apply to voluntary assisted dying (s.3B) or purely data-only research without personal information disclosure (s.3AA(3)).

Duties: Guardians must act in best interests (s.51), consulting wishes, maintaining relationships, and using least restrictive means; they cannot sterilise without SAT consent (s.58) or make abortion decisions (s.45(3A)). Administrators owe fiduciary-like duties (s.70), must keep accounts (s.80), and cannot make charitable gifts without SAT approval (s.72(3)). Donees of enduring powers must exercise diligence, keep records, and report bankruptcy (s.107). Researchers must obtain HREC approval, independent assessments, and report to the Health Minister (s.110ZZC). Health professionals relying on treatment decisions are protected if acting in good faith (s.110ZK, s.110ZLD).

The Public Advocate must investigate complaints (s.97(c)), advance best interests at hearings (s.97(b)), and act on death of sole guardian/administrator (s.99). SAT must apply s.4 principles in every proceeding (s.4(1)), presume capacity (s.4(3)), and prefer less restrictive orders (s.4(4)-(6)).

Rights: Represented persons retain rights except where overridden (s.77 incapacity to contract), with rights to notice (ss.41, 89, 110ZNC), appearance/representation (Sch.1 cl.13), and review (ss.84-90). They may express wishes (s.4(7)), and orders must preserve cultural/linguistic/religious environments (s.51(2)(h)). Capacity to vote can be preserved by declaration (s.111). Advance directives and enduring documents preserve autonomy. Confidentiality of personal information is protected (s.113), with limited publication restrictions (Sch.1 cl.12). Immunity applies to those performing functions without dishonesty or bad faith (s.114). Appeals and internal reviews provide procedural fairness (Part 3; s.17A).

Persons responsible and enduring guardians have priority rights to decide but must follow best interests (ss.110ZD(8), 51, 70). Researchers and health professionals gain statutory defences when complying (ss.110ZX, 110ZY, 110ZK, 110ZLD).

Penalties are targeted. Unauthorised sterilisation of represented persons or those with pending guardianship applications attracts $4,000 and 2 years imprisonment (s.57(1)-(2)). Performing abortion on an incapacitated adult without advance directive or SAT consent (where required) incurs the same penalty (s.110ZLB). Medical research sterilisation, ECT, or abortion carries 2 years/$10,000 (s.110ZT(3)-(4)).

Obstructing a guardian with warrant incurs $1,000 (s.49(4)). Breaches of confidentiality attract $5,000 (s.113). Donees failing to keep records face $2,000 (s.107(1)(b)). Publication of identifying accounts or lists of proceedings is a crime punishable by $10,000 (body corporate) or 1 year/$5,000 (individuals), with summary penalties of $5,000/$2,500 (Sch.1 cl.12).

Enforcement occurs via SAT directions (ss.47, 74), variation/revocation of orders (s.90), setting aside transactions (s.82), recovery of property (s.77(2)), Public Trustee account examinations with liability certificates enforceable as debts (s.80(6)), security enforcement (s.81), and Supreme Court appeals with cost recovery (s.37). Criminal proceedings require Attorney General consent for publication offences (Sch.1 cl.12(7)). SAT may award costs where a party acted in best interests (s.16(4)).

The Act is expressly subject to Supreme Court inherent jurisdiction (s.3A) and does not authorise voluntary assisted dying (s.3B). It cross-references the State Administrative Tribunal Act 2004 extensively for procedure (ss.16(5), 17(2), Sch.1), evidence (s.29), and costs. Mental health overlaps appear in definitions (s.3(1)), Public Advocate functions (s.98 referring to Criminal Law (Mental Impairment) Act 2023), and transitional provisions (Sch.5 Div.2).

Treatment decisions interact with the Mental Health Act 2014 (electroconvulsive therapy definition, exclusion from urgent treatment in s.110ZH), Public Health Act 2016 (abortion definition in s.3(1A)), and Voluntary Assisted Dying Act 2019. Enduring powers reference the Property Law Act 1969 and Transfer of Land Act 1893 (s.103). Wills and testamentary capacity link to the Wills Act 1970 s.40 (s.111A) and Sch.2.

Interjurisdictional recognition (ss.44A, 83D, 104A, 110O, 110ZA) creates comity with reciprocating States. Research provisions align with the National Statement on Ethical Conduct in Human Research (s.110ZO). Confidentiality supplements Freedom of Information Act 1992 (s.3(1)). Legal profession rules constrain advocacy roles (ss.51(3), 70(3)). The Act overrides common law only to the extent stated, preserving common law treatment decisions (s.110ZB).

The most significant recent change is the Guardianship and Administration Amendment (Medical Research) Act 2020, inserting Part 9E. This responded to ethical gaps in involving incapacitated persons in research, particularly during emergencies like pandemics. It introduced research decision-makers (s.110ZP), urgent research pathways (s.110ZS), mandatory independent medical assessments (ss.110ZU-110ZW), HREC approval, and parliamentary reporting (ss.110ZZC-110ZZD). The 2023 amendments to s.3AA refined "medical research" exclusions.

The Abortion Legislation Reform Act 2023 added detailed abortion consent rules (ss.25A-25C, 110ZLA-110ZLD, 110ZNA-110ZND), requiring Full Tribunal for incapacitated adults, creating offences, and specifying appeal stays. This aligned guardianship law with decriminalised abortion while protecting vulnerable persons.

The Criminal Law (Mental Impairment) Act 2023 updated s.98 and cross-references. Earlier, the Acts Amendment (Consent to Medical Treatment) Act 2008 introduced Parts 9B-9D for advance directives and persons responsible, driven by recommendations from the Law Reform Commission of Western Australia to clarify substitute decision-making and reduce reliance on common law.

These changes reflect evolving recognition of autonomy in health, research ethics post-National Statement updates, and alignment with national schemes. Transitional provisions in Sch.5 ensure continuity for pre-existing orders.

The source text does not detail specific court challenges; however, the appeal structure (Part 3 Div.3) contemplates errors of law/fact or jurisdictional excess (ss.21, 25B). SAT determinations are reviewed on material before the Tribunal plus further evidence (s.29), with Court powers to substitute, remit, or grant prerogative relief (s.30). Status quo generally continues pending appeal (s.28), except abortion decisions which are stayed (s.25C) and sterilisation consents which are suspended during appeals (s.57(3)).

Controversies implicit in the text centre on best interests vs autonomy (s.4 tension with s.110S(3) change-of-mind test), scope of "urgent treatment" after suicide attempts (s.110ZIA), and research risk thresholds (s.110ZW). The requirement for Full Tribunal in sterilisation (s.56A) and abortion (s.110ZNA) reflects legislative caution around irreversible procedures. Public Advocate reports under s.101A allow raising systemic concerns with the Minister. No specific case citations appear in the Act; controversies are addressed through mandatory periodic reviews (s.84), the 3-year review of Part 9E (s.110ZZE), and leave requirements for reviews (s.87).

Most practitioners miss that an advance health directive does not automatically revoke on making an enduring power of guardianship (s.110T); treatment decisions in the directive retain priority under s.110ZJ unless the directive itself states otherwise. The "change of mind" test in s.110S(3)-(5) is subjective-objective: circumstances must be unanticipated and a reasonable person in the maker's position would have changed their mind, requiring consultation with guardians or relatives (s.110S(5)). Many assume any family member can decide treatment; the strict hierarchy in s.110ZD(2)-(4) and "close personal relationship" test (s.110ZD(5)) frequently disqualifies distant relatives.

For research, the independent medical practitioner must not be connected to the research beyond professional interest (s.110ZO definition), creating practical recruitment difficulties in small specialties. Urgent research (s.110ZS) still requires three separate independent assessments before commencing, and the lead researcher must keep seeking a research decision-maker (s.110ZS(3)). Abortion applications require notice to the "nearest relative" (s.110ZNC(2)), which can include estranged siblings before grandparents, often surprising families.

Plenary guardians cannot make wills (s.45(4)), but can apply under Wills Act 1970 s.40 (s.111A). Administrators cannot deal with the represented person's property as their own (s.69(4)), yet transactions bind the estate (s.79). The Public Advocate becomes guardian/administrator automatically on death of a sole appointee (s.99), but only until SAT review. Costs orders against estates are discretionary and require best-interests findings (s.16(4)). Finally, s.4(3) presumption of capacity is rebuttable only to SAT's satisfaction; health professionals relying on purported decisions are protected only if their belief in incapacity was reasonable and good faith is shown (s.110ZK(3)).

Compliance begins with capacity assessment using s.4(3) presumption. For practitioners, obtain written advance directives or confirm enduring documents are executed per ss.104, 110E, 110Q (two witnesses, one qualified; acceptance forms). When capacity is doubtful, apply to SAT under s.40 (guardianship/administration), s.106 (declare incapacity for power of attorney), s.110V (advance directive validity), s.110ZF (person responsible declaration), s.110ZM (treatment decision priority), or s.110ZZ (research review). Notices must be 14 days (ss.41, 89) or 7 days (ss.60, 110ZNC), personally served with explanations in accessible language (s.115(2)).

Guardians/administrators must document best-interests reasoning (ss.51, 70), consult where possible, and seek SAT directions for uncertainty (ss.47, 74). Research compliance requires HREC approval, three independent assessments (best interests, capacity recovery, risks), written/oral reporting to decision-makers (ss.110ZU-110ZW), and discontinuation if capacity returns (s.110ZR(7), s.110ZS(5)). Researchers report to Health Minister within approved form (s.110ZZC).

Health professionals rely on s.110ZK/s.110ZLD good-faith defences by sighting documents and recording assumptions. Maintain records for SAT inspection (s.112). For interstate clients, check Gazette notices for reciprocal arrangements (ss.44A(2), 83A). Annual SAT reviews (s.84) and account lodgements (s.80) are mandatory unless exempted. Public Advocate involvement should be invited early for unrepresented persons (s.97). Seek legal advice on Sch.2 functions before major transactions. Regular file audits against s.4 principles prevent least-restrictive breaches. In urgent scenarios, document impracticability of obtaining consent (s.110ZI) contemporaneously.
