Relevant factual matters
2 When sentencing the trial judge summarised the relevant facts in the following terms:
"The circumstances giving rise to these convictions were about 10.00 pm on Monday 5 January 2004 Mr Wayne Williams was working in his backyard. He gave evidence that Spurling and Everuss walked into his driveway and demanded money. The victim knew both men. He was grabbed by Everuss and hit. Spurling was standing near a trailer in the driveway. Everuss and he fought around the house to a fence and he ran back down the driveway to escape. Spurling pushed him backwards. He said: 'I only have ten dollars' and proffered his wallet. It was taken and both men left.
He went to the hospital that evening and went to the police to complain the following day. On that day he was handed a wallet by a plumber who had seen it on the front lawn. It was the defence of Spurling that Williams was biased against him as a result of a fight which they had had and there had been, prior to this, some agreement as to Spurling [although it is agreed that his Honour meant Everuss] agisting dogs for Williams.
Spurling was to deny the robbery but to admit his presence. He maintained he had gone to Williams house to inform him that he, Spurling, [should read: with Everuss who was going to inform the victim, that he, Everuss], had nothing to do with the break entering and stealing that occurred at the victim's house. It was the case for Everuss that whilst present at the house on that evening and time, he had gone to the house solely to talk to Williams about the break entering and stealing for which he felt he was being unjustly blamed, a conversation made impossible because Williams attacked him. Both men deny demanding money, taking money, or disposing of the wallet."
3 Spurling had given a record of interview which was tendered at the trial. Objection was taken that the record should not be admitted because Spurling was a "vulnerable person" and there had been a failure to comply with Pt 10A of the Crimes Act 1900 (NSW) and with the regulations made pursuant to that Act contained in the Crimes (Detention After Arrest) Regulation 1998.
4 Spurling gave evidence on the voir dire in which he indicated that he had suffered attention deficit hyperactivity disorder (ADHD) since he was eight years old. He was 23 at the time of the interview. He indicated that he had received prescribed medication for the disorder until he was 18 years old and had thereafter self medicated by the use of amphetamines. The interview was conducted by Snr Const Hall, who was not called at the trial, The following exchange occurred:
"Q. All right. How old are you, Travis?
A. 24. 23 turning 24.
Q. No offence Travis. Do you have, do you have learning difficulties or anything like that?
A. Yes, sir.
Q. Your father's out the front?
A. I think he still is.
Q. Would you, would you like your father present in this interview or you feel comfortable by yourself?
A. No, if I can, please.
Q. Interview suspended at 10.45 am Senior Constable leaves the room. Travis, I'll just let you know that this is, this is still operating, this video and audio.

INTERVIEW SUSPENDED
INTERVIEW RESUMED
SENIOR CONSTABLE HALL
Q. Senior Constable Hall enters the room at 10.52 am, daylight savings time. Travis, I've just asked your dad to come up here and sit in the interview, like I explained.
A. Yes, sir.
Q. O.K Mr Spurling, I just want to explain to you on video that you're here for a support role only, O.K. I'll be asking Travis some questions, but you're an observer only. Do you understand that?"
5 The appellant gave evidence that he knew the officer from prior interviews which explained how the officer knew he had learning difficulties. His father was brought into the room as an informal support person although the appellant was not given the opportunity to speak with him at that time. Spurling was cross-examined to the effect that he understood his rights regarding a support person from previous interviews. He also accepted that his rights were explained to him by reference to the document entitled "Caution and Summary Part 10A of the Crimes Act" which both he and his father signed.
6 The custody manager, Sgt Holland gave evidence. One of Sgt Holland's responsibilities as custody manager was to ascertain whether Spurling was a vulnerable person, and he asked Spurling a number of questions in relation to this issue before he was interviewed by Const Hall. Sgt Holland indicated that he did not form the opinion the appellant was a vulnerable person notwithstanding the information Spurling gave him about his ADHD. Sgt Holland was not aware that Const Hall stopped the interview and invited Spurling's father into the room. Sgt Holland said he had explained to Spurling's father his rights and responsibilities as a support person (although not in the terms of the support person for a vulnerable person) and had told him that he was only there as an observer and he could not say anything during the interview and was not to provide legal advice.
7 During the argument on the voir dire his Honour indicated that he was of the view that a person suffering ADHD was not a vulnerable person within the meaning of regulation 5(1) of the Crimes (Detention After Arrest) Regulation 1998 being "(b) persons who have impaired intellectual functioning." At that point counsel for Spurling asked for an adjournment so that he could obtain expert evidence on the question. His Honour declined the application.
