In State v. Green, 86 N.J. 281, 290, 430 A.2d 914 (1981) the Supreme Court of New Jersey held that under circumstances where identification is the key issue, a trial judge's failure to give a specific instruction to assist the jury's evaluation of eyewitness identification constituted reversible error. State v. Green, supra, 86 N.J. at 293, 430 A.2d 914. An appropriate charge in such a case would state that the State's burden of proof on the issue of identification is beyond a reasonable doubt and set forth the respective factual contentions relating to witness descriptions and identifications. Ibid. The Model Jury Charge on identification was considered suitable as a guide. Ibid.
