Factual background
5On the afternoon of Thursday 24 February 2011, the complainant travelled home from her special school near Springwood to Wentworth Falls. Station CCTV footage tendered at the trial shows her boarding through the rear doors of the last carriage of the train at 3.28pm, and walking along the platform at Wentworth Falls at 4.08pm after leaving the train. The guard's compartment was at the very end of the train. The footage shows her shaking hands with the guard immediately before she boarded the train. The cameras at Wentworth Falls did not capture her image as she left the train, but she is shown waving, either to the guard or someone else in the train or on the platform, as the train drew out from the platform.
6An internal door, with a tinted glass window, separated the guard's compartment from the rest of the carriage. It was contrary to RailCorp policy for passengers to travel in the guard's compartment. However, there was no dispute that the complainant had travelled with the guard in his compartment for the conclusion of her journey. How she came to be in the compartment was disputed.
7The complainant walked home from the station, and was driven by her father to a doctor's surgery, where she had an appointment. In the waiting room, and in the surgery carpark after the appointment, she told him that she had been touched by the guard "down there". The complainant also said that the railway man had told her she wasn't to tell anyone what had happened, that she wasn't to say anything. When she returned home that evening, she made a more detailed complaint to her mother, consistent with the particulars of the charges as they were led at trial. The mother called the police, and the complainant told a (female) sergeant that the guard had invited her into his compartment and touched her. A police officer attended on the family's house that evening and secured the complainant's clothes, which were placed into individual bags, and taken to Katoomba Police Station. Police made RailCorp aware of the incident that evening, and the duty security controller called the appellant at 9:30pm that evening. That call was recorded, and the transcript placed into evidence.
8The complainant was herself interviewed for slightly more than 3 hours on the following afternoon, Friday 25 February 2011, by a police officer in the Joint Investigation Response Team. That interview was video-recorded and played at trial (its transcript is in the appeal papers). There was a second video-recorded interview, made on 29 March 2011, which was much shorter, and also played at the trial.
9In her first interview the complainant said that she was standing in the carriage, because all the seats were taken, when the guard came to her, held her hand and pulled her into his compartment, saying "Come, come here. Hold my hand", "I really love you", "Come for a date" and "Stay on the train with me until to get to Katoomba". While he was saying this, she said he was feeling her private parts.
10The count of aggravated sexual assault was that the appellant penetrated the complainant's vagina with his finger. The complainant described this in her first interview, stating that he had pulled down the zipper on her pants, and that his fingers were inside her clothes, and not touching her skin, but "the private part":
"Q. His fingers touched your private part?
A. Yeah, yeah. Oops.
Q. And what do you call the private part?
A. Ah, the gina.
Q. OK. And what ... did the fingers do on your gina?
A. Ah, it was, it was starting to sting and burn.
Q. OK. How come it was stinging and burning?
A. Ah, because, because I, I because he had his fingers in there and it was starting to, inside the gina was starting to burn ---
Q. OK.
A. --- when, he had his fingers in.
Q. So he had his fingers inside your vagina ---
A. Yeah.
Q. --- and you're telling me it started to sting and burn.
A. Yeah.
Q. Do you know how far his fingers were in your vagina when it started to sting and burn?
A. Ah, ah, I don't know.
Q. That's OK.
A. I don't know.
Q. OK. What else could you feel? You could feel stinging and burning.
A. Yeah.
Q. What else could you feel?
A. It, It was starting to be sore and uncomfortable when, when he was having his fingers inside."
11The counts of aggravated indecent assault were that the appellant had touched the complainant's right breast and her left breast, and that he had put his hand inside his own pants and held his erect penis close to her groin. The complainant described the appellant touching both of her breasts in her first interview. Each assault was, according to her description, different. First, she said that the appellant held his hand under the complainant's shirt and over the outside of the bra on her right breast:
"Q. You said you had a bra on.
A. Yeah.
Q. Was his hand on the outside of the bra or on the inside of the bra touching your breast or something else?
A. Ah, outside the bra.
Q. OK.
A. Yeah.
Q. All right.
A. Yeah.
Q. And on the other side on your left breast ---
A. Yeah.
Q. --- he had his hand on the outside of your T-shirt is what you said, is it?
A. Yeah."
12The complainant described the event of him holding his penis in a further interview she gave on 29 March 2011:
"Q. ... What could you see?
A. I, I didn't saw it. I, I felt it. Yeah. I only, I felt it. Yeah.
Q. Tell me more about how you felt it.
A. He, he was, I, I felt it because he, 'cause he was moving around in, I, I felt it when he was moving with his half of his arm went in his pants.
Q. Yeah.
A. And I felt his hands, I felt his hand moving to, to, to, you know, like a, like a cardboard."
13It was not suggested by the appellant that, if the complainant's evidence was accepted, it was insufficient to establish the conduct constituting each of the counts on the indictment. Accordingly, it is not necessary for present purposes to reproduce or otherwise summarise the detail of the balance of the complainant's account; it suffices to say that it proceeds in the same linguistic style as may be seen from the passages reproduced above, using very simple but direct language.
14Turning to the near-contemporaneous accounts given by the appellant, as noted above, he was called by the duty security controller, Mr Chris Kalogeropoulos, at around 9.30pm that evening. After confirming that he had been the guard on the relevant train, this conversation occurred:
"CK: Did you have any incidents on that at all up at Springwood or Wentworth Falls, an assault or anything?
JP: Incident? No.
CK: No? No incidents? Alright.
JP: There were two angry customers knocked the doors why the train is running slow and I think some naughty boys also.
CK: Right, okay.
JP: And then (inaudible) I just - there are two big girls and I just assisted one disabled girl from - from, I think, I don't know from where she got on but she knocked, she needed to get off at Wentworth Falls and she, I think she is upset with those boys.
CK: Okay, alright.
JP: And I just assist her.
CK: Okay.
JP: There was no place to seat her and I think she has a walking and speaking problem.
CK: Okay, alright then, no problem.
JP: I just asked her to sit in my chair, then I was standing all the time because it was two stops she wanted to get off."
15As is apparent from that transcript, the appellant spoke English as a second language, less than perfectly, and with an Indian accent. He gave evidence that passengers often had difficulty understanding him because of his accent.
16On the afternoon of 25 February 2011, in the execution of a search warrant, a detective senior constable and around four other officers attended upon the appellant's house and seized some of the appellant's clothing. The execution of the warrant was video-recorded, and during the process, the appellant was asked and answered questions about what had occurred the previous day (having been told that he did not need to say anything but that anything which he did say would be recorded and might be used in evidence). The appellant was cross-examined as to the disparities between his testimony to the Court in 2013 and what he told police the day after the incident. During that search, there were these questions and answers:
"Q. ... [S]o you are not allowed to have passengers inside the guard compartment, is that right?
A. Yes.
Q. Okay, so what happened - you said she was having trouble?
A. Yes, and she said, 'I would like to sit there, so could you please help me?' and I said, 'Yes.' Normally - sometimes it is permissible for aged people, or people with troubles - if they are being harassed or abused on the train, so we help them up to their destination. I asked the lady, 'Where you want to?' 'Wentworth Falls'. She was sitting there during all that time. I was stick to the door. Only the one person now that I'm thinking because my boss ring me at night when I'm finished my job. He said, 'Any complaint or assault or anything?' And I said, 'No complaint'."
17There were two other documents which dated, or purported to date, from the day. One was a "Guards Report of Late Running Trains". The evidence was that it was standard procedure for the form to be completed when a train ran late (as the train on 24 February 2011 was). The appellant completed it, lodged it with his employer and kept a carbon copy. On it he had written "Train is late as slow running train after Springwood. Assist to disabled passenger". The appellant also kept a diary at home with work-related information in it, including overtime he had worked. The page for 24 February includes the words "late train to Katoomba 12 mins and assist disabled girl to WWF".
18To summarise the near-contemporaneous evidence dating from within 24 hours of the complainant's train trip, there were, first, complaints to her father and mother. Secondly, there was an extensive interview by the complainant with a police officer, which was recorded. Thirdly, there was a conversation between the appellant and his RailCorp supervisor, which was recorded. Fourthly, there was a conversation with the police and the appellant during the execution of the search warrant, which was video-recorded. Fifthly, there were two documents in the appellant's hand - the late train slip, and his personal diary. Finally, there was CCTV footage from some of the stations on the line, including footage clearly showing the complainant entering the carriage (through the double-doors next to the guard's compartment). They shook hands as the complainant entered the train. The CCTV footage does not show the complainant leaving the carriage, but it does show her waving, most likely to the guard, as the train pulled out of Wentworth Falls.
