2 SPERLING J: On 16 October 1998, the appellant was convicted of the following offences in a trial before Grogan DCJ and a jury: first, that on 24 June 1996 at Holsworthy he stole motor vehicle registration no. TXM 901; secondly, that on 29 June 1996 at Birrong, being armed, he assaulted Lynne Williams with intent to rob her; thirdly, that on 29 June 1996 at Birrong, being armed, he robbed John Waterson; and, fourthly, that on 29 June 1996, being armed, he robbed Marie Nicolaou.
3 So far as concerns the events of 29 June 1996, the Crown case was as follows. The accused entered the Tuckerbag Supermarket at Birrong. He held a sawn-off shotgun against Ms Williams, an employee, demanding money from a cash register. She noticed a green coloured tattoo on the back of one of the appellant's hands. The cash register failed to open.
4 Another employee, Mr Waterson, was then accosted by the appellant. Money was again demanded and was given to the appellant from one of the cash registers.
5 Another employee, Ms Nicolaou handed over further money on demand. She also noticed a green coloured tattoo on the back of one of the offender's hands. The appellant had tattoos on his hands similar to those described by the witnesses.
6 On 30 June 1996, Mr Waterson made a picture identification of the appellant from eleven photographs shown to him by the police.
7 Many months later, Ms Williams, Ms Nicolaou and another employee who was in the store at the time, Ms Pignat, each, separately, failed to make a positive identification from a video of still photographs, although Ms Nicolaou selected two of the pictures as being similar to the robber, one of which was a picture of the appellant taken on 7 August 1996 after his arrest.
8 The appellant has appealed against the convictions relating to the offences alleged to have occurred on 29 June 1996. The grounds of appeal are as follows.
