What it does
The Criminal Law (Detention and Interrogation) Act 1995 (Tas) establishes a statutory framework governing the detention of persons in custody for the purposes of questioning and investigation, while codifying safeguards against arbitrary or oppressive police conduct. At its core, s 4(1) mandates that every person taken into custody (other than under a Supreme Court warrant) must be brought before a magistrate or justice "as soon as practicable" unless released unconditionally, admitted to bail, or dealt with under s 34 of the Justices Act 1959. Section 4(2) then creates a carefully circumscribed exception permitting detention for a "reasonable time" to question the person or conduct investigations in which they participate, plus time to arrange and effect transport to a judicial officer.
The concept of "reasonable time" is not left at large. Section 4(4) prescribes a non-exhaustive list of 13 matters that must be considered, ranging from the number and complexity of offences (s 4(4)(a)), through logistical steps such as collating material (s 4(4)(b)), transporting the suspect (s 4(4)(c)), consulting legal practitioners or support persons (s 4(4)(f)–(g)), providing medical attention (s 4(4)(h)), facilitating witness intermediaries under the Evidence (Children and Special Witnesses) Act 2001 (s 4(4)(ha)), and conducting identification parades or forensic examinations (s 4(4)(k)–(l)). This list reflects a deliberate legislative attempt to balance investigative necessity against the presumption in favour of prompt judicial oversight.
The Act also regulates the treatment of intoxicated persons. Inserted by the Justice and Related Legislation (Miscellaneous Amendments) Act 2018, s 4(2)(ab) permits continued detention where a police officer believes on reasonable grounds that the person is intoxicated and either poses a risk of injury or damage or is incapable of self-protection. Release decisions are governed by s 4(5), which sets out four pathways: sobriety, safe handover to a responsible person, handover to a hospital or charitable facility, or a risk assessment demonstrating the person no longer meets the danger criteria. A hard outer limit of 8 hours is imposed by s 4(6), extendable by a commissioned officer for a further 4 hours under s 4(7) if the conditions for release are unlikely to be met by the initial deadline. These provisions represent a significant operational expansion from the 1995 original text.
