The construction issue
6 As noted, reg 72(1) of the Youth Justice Regulations provides that a detainee must not be isolated in a cell except under s 153(5) of the Act. Section 153(5) of the Youth Justice Act provides that if the superintendent of a detention centre is of the opinion that a detainee should be isolated from other detainees to protect the safety of another person or for the good order or security of the detention centre, the superintendent may isolate the detainee for a period not exceeding 24 hours or, with the approval of the Director of Correctional Services appointed under the Prisons (Correctional Services) Act 1950 (NT), not exceeding 72 hours.
7 Section 154(1) of the Youth Justice Act permits the superintendent of a detention centre to apply by telephone to a magistrate for approval to transfer a detainee if the superintendent is of the opinion that an emergency situation exists and a detainee should be temporarily transferred to a prison to protect the safety of another person. By s 154(2) this power is available only if the detainee is 15 years of age or older. Section 154(3) provides that if the magistrate approves the transfer, the superintendent may arrange for the detainee to be transferred from the detention centre to a prison. By s 154(7) the period of transfer of the detainee must not exceed 24 hours, but s 154(8) provides that the superintendent may apply to a magistrate for an extension of the period of transfer.
8 The appellant was a detainee at Don Dale. He, along with other detainees, was involved in a serious disturbance at Don Dale on 26 December 2011. The superintendent of the detention centre applied for, and a magistrate approved, an order for transfer of the appellant to a prison under s 154(1) and (3) of the Youth Justice Act, and subsequent extensions under s 154(8) for an extension of the period of transfer were granted. As a result, the appellant was transferred to the Darwin Correctional Centre between 28 December 2011 and 2 January 2012.
9 The primary judge decided that the conditions of the appellant's detention at the Darwin Correctional Centre involved the appellant being isolated: [416]. As noted, however, the primary judge did not accept that s 153(5) of the Youth Justice Act or reg 72(1) of the Youth Justice Regulations applied to the appellant while he was transferred under s 154(1). Accordingly, the primary judge concluded that the isolation of the appellant was authorised under s 6(2) of the Prisons (Correctional Services) Act which, at the relevant time, provided that the Director had control of all prisons and the custody of all prisoners: [406]-[408].
10 In argument during the appeal the appellant accepted that in order to succeed on this issue we had to conclude that s 153(5) of the Youth Justice Act and reg 72(1) of the Youth Justice Regulations applied to the appellant while he was transferred to Darwin Correctional Centre. It was not sufficient for the appellant to persuade us that while he was transferred to Darwin Correctional Centre the appellant was not a "prisoner" within the meaning of s 6(2) of the Prisons (Correctional Services) Act. This concession was properly made, as the only case the appellant had made below was that his isolation while in the Darwin Correctional Centre contravened s 153(5) of the Youth Justice Act and reg 72(1) of the Youth Justice Regulations and was thereby unlawful. The appellant did not contend below that his isolation, while in the Darwin Correctional Centre, was otherwise unlawful under the Prisons (Correctional Services) Act. This said, the appellant's contention that the appellant was not a "prisoner" under the Prisons (Correctional Services) Act was an integral part of the appellant's argument as to the proper construction of s 153(5) of the Youth Justice Act and reg 72(1) of the Youth Justice Regulations both before the primary judge and on appeal.
11 The problem for the appellant is that the arguments on his behalf fail to confront the text, context and objects of the Youth Justice Act and the Youth Justice Regulations.
12 Starting with the text, the obvious issue is this. Section 153(5) of the Youth Justice Act (the power of the superintendent to isolate a detainee) is a specific extension of the function given to the superintendent in s 153(1) of that Act. The function in s 153(1) is for the superintendent to "maintain discipline at the detention centre" (emphasis added). Section 152(3), however, provides that the "powers and functions of the superintendent of a detention centre in relation to a detainee are not altered or diminished by the fact that the detainee may be outside the precincts of, or absent from, the detention centre". How does s 152(3) relate to s 153(5)? The short answer is that s 152(3) does not transform functions of the superintendent in relation to a detainee which on their proper construction are only exercisable at the detention centre into functions exercisable in relation to a detainee who is not at the detention centre.
13 The immediate textual and contextual indicators that s 153(5) and, thus, reg 72 involve a function exercisable in relation to a detainee only at the detention centre for which the superintendent is superintendent are that:
(1) the power in s 153(5) is conditioned on the opinion of the superintendent who is, by operation of s 151 of the Youth Justice Act, the "superintendent for a detention centre" (emphasis added);
(2) the substance of the required opinion is that "a detainee should be isolated from other detainees" (emphasis added);
(3) to be isolated there must be a physical place of isolation to which the detainee may be taken;
(4) the only place of isolation in respect of which the superintendent has functions under the Youth Justice Act is the detention centre for which the superintendent is the superintendent;
(5) it follows that the function in s 153(5) of causing a detainee to be isolated necessarily involves a place of isolation at the detention centre;
(6) this is supported by the fact that the isolation contemplated by s 154(5) is isolation from other detainees and not from, for example, other patients at a hospital or prison to which the detainee has been transferred;
(7) other detainees will be at the detention centre unless themselves subject to an order or permission to be absent from the detention centre;
(8) the proper construction of s 153(5) cannot depend on the mere happenstance that a detainee may be in a hospital or a prison where there are other detainees meaning that it might be theoretically possible for such a detainee to be isolated from these other detainees. Rather, it is necessary to recognise that s 153(5) assumes that the power in s 153(5) will be exercisable by a superintendent only in respect of a place within the detention centre for which the superintendent is superintendent;
(9) accordingly, reg 72(1) of the Youth Justice Regulations, which must be read consistently with s 153(5), concerns the function of the superintendent under s 153(5) to cause a detainee to be isolated from other detainees at a place forming part of the detention centre; and
(10) as a result, the constraint in reg 72(1) (a detainee must not be isolated in a cell except under s 153(5) of the Act) applies to the isolation of a detainee in a cell at the detention centre.
14 A more detailed consideration of the statutory scheme of the Youth Justice Act and the Youth Justice Regulations, confirms these conclusions.
15 The Youth Justice Act establishes a special regime for dealing with youths who have committed or are alleged to have committed offences: ss 3 and 4 of the Youth Justice Act.
16 A "youth" is a person under 18 years of age: s 6(1) of the Youth Justice Act.
17 Parts 1 and 2 of the Youth Justice Act contain special procedures for the investigation, apprehension, remand, arrest, interview, search, prosecution, charge, bail, and identification of any youth. Part 3 concerns the diversion of youth who are believed on reasonable grounds to have committed offences. Part 4 concerns the Youth Justice Court. Part 5 concerns Court proceedings involving a youth. Under s 65(1)(d) the Court may remand a youth in custody. By s 65(2) if a youth is remanded in custody, he or she can be detained in a detention centre or, if the youth has turned 15 years of age, in either a prison or detention centre as ordered by the Court. The Supreme Court has the same powers under s 82(1). Section 5(1) defines "detention centre" to mean a youth detention centre approved under s 148 of the Youth Justice Act and "prison" to have the meaning in the Prisons (Correctional Services) Act.
18 Part 6 of the Youth Justice Act involves the disposition of proceedings involving a youth. Under s 81(6) the Court must impose a sentence of detention or imprisonment on a youth only as a last resort, and a sentence of imprisonment only if there is no appropriate alternative. Section 83(1) involves sentencing options, which include detention or imprisonment under s 83(1)(i)-(l). By s 83(3) the Court must not order the imprisonment of a youth who is less than 15 years of age.
19 Part 8 of the Youth Justice Act concerns youth detention centres. By s 148 the "Minister may approve an establishment to be a youth detention centre for this Act". By s 149(1) a "youth must not be admitted to a detention centre except in accordance with this Act".
20 Under s 151(1) of the Youth Justice Act the Director must appoint an employee to be the superintendent for a detention centre. By s 151(2) the superintendent of a detention centre is responsible, as far as practicable, for the physical, psychological and emotional welfare of detainees in the detention centre. Section 152(1) provides that the superintendent of a detention centre has the powers that are necessary or convenient for the performance of his or her functions. By s 152(3):
The powers and functions of the superintendent of a detention centre in relation to a detainee are not altered or diminished by the fact that the detainee may be outside the precincts of, or absent from, the detention centre.
21 Section 153(1) of the Youth Justice Act provides that the superintendent of a detention centre must maintain discipline at the detention centre. Section 151(3) provides that:
The superintendent of a detention centre:
(a) must promote programs to assist and organise activities of detainees to enhance their wellbeing; and
(b) must encourage the social development and improvement of the welfare of detainees; and
(c) must maintain order and ensure the safe custody and protection of all persons who are within the precincts of the detention centre, whether as detainees or otherwise; and
(d) is responsible for the maintenance and efficient conduct of the detention centre; and
(e) must supervise the health of detainees, including the provision of medical treatment and, where necessary, authorise the removal of a detainee to a hospital for medical treatment.
22 Sections 153(5) and 154 of the Youth Justice Act have been identified above.
23 Section 155 provides that the superintendent of a detention centre may approve handcuffs or a similar device to restrain normal movement to be used when escorting a detainee outside the detention centre.
24 Section 157(1) of the Youth Justice Act provides that the superintendent of a detention centre may delegate in writing any of his or her powers and functions under the Youth Justice Act to a member of the staff of the detention centre or a person authorised by the Director for s 165(b). Section 165(b) provides that the superintendent of a detention centre may, subject to the order of the Court under which the detainee is detained, permit a detainee to be absent from a detention centre for any period for a purpose approved by the superintendent if in the custody and under the supervision of, amongst other people, a person authorised by the Director. Section 157(2) provides that a police officer or a prison officer within the meaning of the Prisons (Correctional Services) Act, if called upon by the superintendent of a detention centre to assist in an emergency situation or in preventing an emergency situation from arising, is taken to have been delegated the powers of the superintendent necessary to perform the superintendent's functions under s 151(3)(c).
25 By s 158(1) of the Youth Justice Act the superintendent of a detention centre must keep a register containing certain particulars in relation to every detainee in the detention centre to the extent the particulars are reasonably ascertainable by the superintendent. Section 158(2) provides that if a detainee is absent from the detention centre for a period without being discharged from custody, the register must also contain certain information in relation to the detainee including, among other things, "the name and address of the person in whose care and custody the detainee was placed for the period of the absence and that person's relationship (if any) to the detainee".
26 Section 164 of the Youth Justice Act provides that, unless the Director directs to the contrary under s 164(4):
(1) A detainee who turns 18 years of age while serving a sentence of detention, or on remand in custody, in a detention centre must, within 28 days after turning that age, be transferred to a prison to serve the remainder of the sentence or period of remand.
(2) If a detainee is transferred to a prison under subsection (1), the order of the Court sentencing the youth to a period of detention in a detention centre is taken to be an order sentencing him or her to a term of imprisonment for the period remaining to be served under the order.
27 Under s 166 of the Youth Justice Act the superintendent of a detention centre may release a detainee from the detention centre earlier than the detainee is entitled to be released in certain circumstances but more than 48 hours earlier than he or she would be entitled to be released but for s 166.
28 Section 167(1) of the Youth Justice Act provides that the superintendent of a detention centre or a member of the staff of the centre may exercise the powers of a police officer to arrest and take into custody a detainee who has escaped from a detention centre.
29 Section 178 of the Youth Justice Act provides that the superintendent of a detention centre must move a detainee from the detention centre to a hospital, in the event of illness of the detainee, on the order of the Director, a medical practitioner, or the Court. Section 179 is in these terms:
(1) This section applies if a detainee is moved to a hospital under section 151(3)(e) or 178.
(2) The superintendent of the detention centre from which the detainee was moved must make the necessary arrangements with the person in charge of the hospital to ensure the security and good order of the detainee while the detainee is in hospital.
(3) While in the hospital, the detainee remains in lawful detention for this Act.
(4) If the detainee is discharged from the hospital and his or her sentence of detention has not expired, the detainee must be returned to the detention centre to serve the remainder of the sentence.
30 Part 5 of the Youth Justice Regulations concerns "Detention centres and detainees". Regulation 29 contains definitions including:
member of staff, in relation to a detention centre, means a member of the staff of the detention centre; and
Superintendent, in relation to a detention centre, means the superintendent appointed under section 151(1) of the Act for the detention centre.
31 Under regs 30 and 31 of the Youth Justice Regulations the Director or Superintendent may make a determination in relation to any aspect of the management and operation of the detention centre, and determinations relating to conduct of detainees may be referred to as rules of the detention centre. Regulations 32 to 73 concern the management of the detention centre and detainees as admitted to the detention centre (but for reg 52 which relates to visits to a detainee while the detainee is in hospital). Regulation 72(1), identified above, is in Pt 5 of the Youth Justice Regulations. Regulation 72 as a whole is in these terms:
(1) A detainee must not be isolated in a cell except under section 153(5) of the Act.
(2) If a detainee is isolated:
(a) the detainee must be continuously monitored by closed-circuit television or physical observation by a member of staff; and
(b) written observations by a member of staff, including the date, time and name of the member of staff, must be recorded at intervals not exceeding 15 minutes.
(3) The Superintendent must keep a journal recording:
(a) the date and time a detainee is isolated; and
(b) the name of the detainee; and
(c) the reason why the detainee was isolated; and
(d) the time the on-call person in charge was notified and that person's name; and
(e) the observations of a member of staff at intervals not exceeding 15 minutes and the name of the member of staff making the observation; and
(f) the date and time of exercise periods and ablutions; and
(g) details of any approval by the Director for isolation exceeding 24 hours; and
(h) the date and time the detainee is released from the isolation cell.
32 Regulation 73(1) of the Youth Justice Regulations provides that the Superintendent or a member of staff may search a detainee:
(a) when the detainee is admitted to the detention centre; and
(b) on the detainee temporarily leaving, and returning to, the detention centre; and
(c) on the detainee being transferred from the detention centre to a prison or another detention centre; and
(d) on other occasions, and in the manner, directed by the Superintendent as he or she considers necessary.
33 The following propositions are evident from the text of the Youth Justice Act and the Youth Justice Regulations.
34 A youth remanded in custody can be detained in a detention centre or a prison: ss 65(2) and 82(1). The two places are different: ss 5(1) and 148.
35 The fundamental responsibility of a superintendent of a detention centre relates to detainees in the detention centre: s 151(2). However, as the Youth Justice Act provides for the absence of a detainee from a detention centre in certain circumstances, s 152(3) also provides that the functions of the superintendent of a detention centre in relation to a detainee are not altered or diminished by the fact that the detainee may be outside the precincts of, or absent from, the detention centre.
36 The limited circumstances in which a detainee may be lawfully absent from a detention centre are: (a) removal of a detainee from a detention centre to a hospital for medical treatment under ss 151(3)(e) and 178(1), (b) absence of a detainee from a detention centre for any period for a purpose approved by the superintendent if in the custody and under the supervision of identified persons under s 165(b), and (c) temporary removal of a detainee from a detention centre to a prison under s 154.
37 As noted, if a detainee is removed from a detention centre to a hospital as provided for in ss 151(3)(e) and 178(1), then under s 179 the superintendent of the detention centre from which the detainee was moved must make the necessary arrangements with the person in charge of the hospital to ensure the security and good order of the detainee while the detainee is in hospital and while in the hospital, the detainee remains in lawful detention under the Youth Justice Act.
38 There is no equivalent provision in respect of absence from the detention centre under s 165(b) because that section involves absence of a detainee from the detention centre as approved by the superintendent if the detainee is in the custody and under the supervision of identified persons. Section 165(b) therefore assumes that the detainee remains in lawful custody and subject to supervision while absent from the detention centre under s 165(b).
39 The same assumptions are apparent in s 154 - that the detainee is in lawful custody if transferred to a prison and will be subject to the Director's supervision while in the prison. This assumption informs the operation of s 154(3), which provides that if the magistrate approves the transfer, the superintendent may arrange for the detainee to be transferred from the detention centre to a prison. But for s 154(3) such a transfer would be unlawful.
40 The text of the Youth Justice Act supports the soundness of these assumptions given that:
(1) the Director (who is the Director of Correctional Services appointed under the Prisons (Correctional Services) Act) appoints the superintendent for the detention centre: s 151(1);
(2) the superintendent is required to report to and obtain the approval of the Director under various provisions of the Youth Justice Act and the Director otherwise has supervisory functions in respect of a detention centre, as to which see ss 153(5), 158(3), 160(4), 164(4), 165(b)(iv), 176(2), 177(2), and 180(1);
(3) while s 152(3) provides that the powers and functions of the superintendent of a detention centre in relation to a detainee are not altered or diminished by the fact that the detainee may be outside the precincts of, or absent from, the detention centre, the Youth Justice Act recognises the reality that the exercise of those powers and functions is subject to practical constraints;
(4) accordingly, as a superintendent has no powers in respect of (for example) a hospital, s 179(2) requires the superintendent to make the necessary arrangements with the person in charge of the hospital to ensure the security and good order of the detainee while the detainee is in hospital; and
(5) equally, the Youth Justice Act assumes both that the superintendent has no powers in respect of a prison and that the Director does have such powers, with the result that there is no requirement for a provision equivalent to s 179(2) for a detainee while they have been transferred to a prison under s 154. However, there is a requirement for an order of a court to authorise the transfer from the detention centre to a prison to ensure that the holding of the detainee in the prison by the Director it itself lawful.
41 Given these matters, the text of the Youth Justice Act supports the conclusion that s 153(5) applies only to an exercise of power by the superintendent to isolate a detainee from other detainees at the detention centre. Consistently with this, reg 72(1) of the Youth Justice Regulations also regulates an exercise of power by the superintendent to isolate a detainee from other detainees at the detention centre.
42 The context and objects of the Youth Justice Act reinforce this conclusion. The Youth Justice Act assumes the existence of the Prisons (Correctional Services) Act and the functions of the Director and a prison officer under that Act in respect of a prison. Nothing in the Youth Justice Act gives a superintendent or member of staff of a detention centre any functions in respect of a place which is a prison. Sections 152(3) and 153(5) are to be construed in that context.
43 As noted, by s 6(2) of the Prisons (Correctional Services) Act the Director has the control of all prisons and police prisons, and the custody of all prisoners, in the Territory. A prison is a place, premises or institution declared to be a prison under s 10(1). By s 10(2) prisons are to be used for the reception and safe keeping of prisoners or other persons who are otherwise detained in lawful custody. It follows that whether or not a detainee under the Youth Justice Act becomes a prisoner under the Prisons (Correctional Services) Act on transfer to a prison under s 154(1), the Director is responsible for the reception and safe keeping of the detainee under s 10(2).
44 The fact that the detainee remains a detainee during the period of transfer may be accepted. What must also be accepted, however, is that on a magistrate's approval of a transfer to a prison s 154(3) operates so that the superintendent may arrange for the detainee to be transferred from the detention centre to a prison. By this means, a detainee becomes a person detained in lawful custody in a prison under the Prisons (Correctional Services) Act and subject to the control of the Director under s 6(2).
45 In any event, and contrary to the submissions for the appellant, we consider that a detainee also becomes a "prisoner" within the meaning of the Prisons (Correctional Services) Act on transfer to a prison under s 154(3) of the Youth Justice Act. This is because the definition of "prisoner" under s 5 of the Prisons (Correctional Services) Act means either a person committed or remanded by a court and in lawful custody or a person under a sentence of imprisonment. A youth sentenced to detention under s 83(1)(i), (k) or (l) of the Youth Justice Act is not "under a sentence of imprisonment" but, while detained in a detention centre, has been committed and is in lawful custody under the Youth Justice Act. On approval by a magistrate of transfer under s 154(3), the detainee also has been "committed and is in lawful custody" under the Prisons (Correctional Services) Act.
46 The word "committed" in the definition of "prisoner" in s 5 of the Prisons (Correctional Services) Act is not defined. While it may be accepted that the phrases "committed by a court … and in lawful custody" and "remanded by a court and in lawful custody" in that definition mean committed to and in lawful custody in a prison (as opposed to in a youth detention centre), it is clear from the alternative operation of the definition (or under a sentence of imprisonment) that "committed by a court…and in lawful custody" is not confined to a commitment by a court to a sentence of imprisonment. In context, to be "committed by a court…and in lawful custody" as referred to in the definition of "prisoner" in s 5 of the Prisons (Correctional Services) Act means only to be the subject of an order of the court authorising or requiring the detention in lawful custody of the person in a prison. In the present case, a magistrate ordered that the appellant be "confined separately at the Darwin Correction Centre" under s 154(3) of the Youth Justice Act.
47 This construction of the definition of "prisoner" in s 5 of the Prisons (Correctional Services) Act also accords with the operation of s 65(2) of the Youth Justice Act, which provides that a youth remanded in custody under s 65(1) may be detained in a detention centre or, if the youth has turned 15 years of age, in a prison. Such a youth, on entering lawful custody under the Prisons (Correctional Services) Act (a definition extended by s 11 of that Act), becomes a "prisoner" within the meaning of s 5 of that Act as a person "remanded by a court and in lawful custody".
48 As discussed, it may be accepted that the detainee remains a detainee while a prisoner, but that is not the point. Legally and practically, for the duration of the transfer to a prison, the detainee is a prisoner and the responsibility of the Director.
49 This is not to say that s 152(3) of the Youth Justice Act (the powers and functions of the superintendent of a detention centre in relation to a detainee are not altered or diminished by the fact that the detainee may be outside the precincts of, or absent from, the detention centre) necessarily ceases operation altogether on transfer of a detainee to a prison under s 154(1). But functions which, properly construed, are exercisable only while the detainee is at the detention centre, such as s 153(5), are not transformed by s 152(3) into functions exercisable other than at the detention centre.
50 The appellant's arguments to the contrary are not sound. In particular:
(1) s 24(1) of the Youth Justice Act concerns only the position of a youth charged with an offence who is not bailed. The relevant provisions for an order of the Court are ss 65(1)(d) and (2) (remand in custody) and ss 83(1)(i)-(l) (orders for detention which involve the youth being committed to detention);
(2) the relevant point in Binsaris v Northern Territory [2020] HCA 22; (2020) 94 ALJR 664 for present purposes is that a detainee in a detention centre is not a "prisoner": see [53], [87], [93], [95]. This follows as such a detainee is not a person subject to a sentence of imprisonment and is not held in lawful custody under the Prisons (Correctional Services) Act. However, the High Court was not called upon in Binsaris to consider the position of a detainee who has been transferred to a prison under s 154(1) of the Youth Justice Act and who, by operation of s 154(3), has been committed to a prison and is in lawful custody in the prison for the period of the transfer;
(3) the fact that the appellant never ceased to be a detainee is immaterial. The appellant ceased to be a detainee in a detention centre and the functions of the superintendent under s 153(5), accordingly, were not available for so long as the appellant was in prison. As a result, reg 72(1) of the Youth Justice Regulations also had no application;
(4) the function in s 153(5) of the Youth Justice Act is vested only in the superintendent of a detention centre. It follows that reg 72 of the Youth Justice Regulations concerns that function of the superintendent. For the reasons discussed, s 152(3) does not transform that function, exercisable only at the detention centre on the proper construction of s 153(5), into a function exercisable outside of the detention centre. It follows that reg 72 also does not apply outside of the detention centre;
(5) the notion that this construction would permit the superintendent to isolate a detainee outside of a detention centre in contravention of reg 72 is misconceived. As Binsaris exposes, specific statutory power is required to do to a detainee what would otherwise be tortious conduct (see, in particular, Binsaris at [25] citing Coco v The Queen [1994] HCA 15; (1994) 179 CLR 427 at 436). In other words, the construction we prefer does not permit evasion of the limits on the superintendent's power; and
(6) as noted, the appellant did not run any case to the effect that the isolation of the appellant at the Darwin Correctional Centre was not authorised by the Prisons (Correctional Services) Act and cannot (and did not seek to) do so on appeal.
51 For these reasons the first ground of appeal must be rejected.
