South Australia act
This short South Australian law sets the legal moment when a person is treated as dead for the State's laws. Mechanically, it says a person has died when either:
(See section 2.)
The definition applies "for the purposes of the law of this State" (s 2). That means any legal process that depends on knowing whether a person is dead — for example, registration of death, administration of estates, enforcement or termination of contracts, and any statutory rights or duties that hinge on death — will use this definition as the legal trigger.
The Act itself does not set out who must make the medical determination, what tests must be used, how long to wait, or what documentation is required. It provides the legal threshold (irreversible cessation of brain function or circulation) but leaves the procedural details unstated (compare the text of s 2). That creates a practical requirement for other actors — health practitioners, hospitals, coroners, registrars and courts — to apply the definition when certifying or resolving questions of death, using whatever medical, administrative or judicial procedures are available or adopted elsewhere.

The statutory purpose, stated in the Act's short title and opening language, is to "provide a definition of death for the purposes of the law of South Australia" (short title and s 2). Treated as a claim: the Act provides a clear legal trigger (brain cessation or circulatory cessation) to be used across State law.
Costs and incentives: the Act imposes no explicit fees or administrative levies, but it creates operational consequences. Because the statute declares the conditions that legally constitute death (s 2) but does not prescribe diagnostic procedures, the practical costs fall to medical and administrative systems that must establish and document those conditions in practice. Those actors bear the compliance and evidentiary burden of translating the statutory words into routine practice.
Trade‑offs and opportunity costs: by adopting a brief, high‑level definition (s 2) the Act reduces statutory ambiguity about the legal standard but transfers the work of specifying procedures to other instruments (clinical protocols, registration rules, or case law). The trade is legislative simplicity in return for reliance on external professional or administrative rules to manage implementation.
Implementation risk and discretion: because the Act does not define "irreversible" or the tests for "cessation of all function of the brain" or for circulatory cessation (s 2), there is room for medical judgment, institutional protocols, and ultimately judicial interpretation to decide difficult cases. That creates potential for variation in practice and for disputes that may require court resolution.
Effects on private choice and private actors: the Act constrains when private legal rights and obligations tied to death can be exercised by setting the legal trigger (s 2). It does not itself alter private contracts or estates, but it determines the event (death) that activates those arrangements and thus affects when people and organisations can act under law.
