7. For these reasons, it is most undesirable that police officers who have arrested a person on a charge of having committed a crime should arrange for potential witnesses to identify that person except at a properly conducted indentification parade. Similarly, speaking generally, an identification parade should, wherever possible, be held when it is desired that a witness should identify a person who is firmly suspected to be the offender. However, there is little support to be found in the authorities for the view that a conviction must necessarily be quashed if it is based on evidence that the accused was identified other than at an identification parade at a time when he had been charged or was definitely suspected, even though there was no valid reason why an identification parade could not have been arranged. The judgment of this Court in Davies and Cody v. The King [1937] HCA 27; (1937) 57 CLR 170 suggests that the proper approach is to consider whether the conviction can safely be sustained on the whole of the evidence. In England, although the courts constantly insist on the importance of holding an identification parade, the Court of Criminal Appeal in Reg. v. Seiga (1961) 45 Cr App R 220 dismissed an appeal against conviction in a case where photographs were used to identify the accused although he had been arrested and no reason was given why there should not have been an identification parade. In that case the witness who identified the accused in court had previously been shown, by a police officer, a group of photographs, including one of the accused. The Court of Criminal Appeal disapproved of the conduct of the police officer, but nevertheless sustained the conviction. In Australia, the question arose in Reg. v. Bouquet (1962) SR (NSW) 563 where the accused was identified by a witness who was shown a number of photographs after the accused had been arrested. An appeal against conviction was allowed on other grounds, but Sugerman J. (1962) SR (NSW), at p 568 said that the use of photographs instead of an identification parade goes to the weight and sufficiency of the evidence rather than its admissibility and may be specially significant when there is no other evidence identifying the accused. Wallace J. (1962) SR (NSW), at p 574 , at p. 574, said that the procedure of holding an identification parade should be followed except in special circumstances. The other Australian cases were not so directly concerned with this question. In Reg. v. Goode (1970) SASR 69 the accused was identified from photographs before his arrest, and no parade was subsequently held; the Court quashed the conviction because the warning given to the jury was insufficient. In R. v. Fannon and Walsh (1922) 22 SR (NSW) 427 and Reg v. Doyle [1967] VicRp 82; (1967) VR 698 , and also in the New Zealand case Reg. v. Russell (1977) 2 NZLR 20 , identification parades were held, but only after the identifying witness had identified the accused from a number of photographs produced by the police. In Reg. v. Doyle and Reg. v. Russell the photographs were shown to the witnesses during the investigation of the crime and before the arrest of the suspect; the report in R. v. Fannon and Walsh does not make it clear at what stage the photographs were shown. In all these cases the evidence of identification by means of the photographs was held admissible and the convictions were upheld. In Reg. v. Russell (1977) 2 NZLR, at p 27 , Richmond P. said:
