Simon & Ors. v. State of Karnataka -2004 (2) SCC 694

“14…………mere identification of an accused person at the trial for the first time is from its very nature inherently of a weak character. The purpose of a prior test identification is to test and strengthen the trustworthiness of that evidence. Courts generally look for corroboration of the sole testimony of the witnesses in court so as to fix the identity of the accused who are strangers to them in the form of earlier identification proceedings. This rule of prudence, however, is subject to exceptions, when, for example, the court is impressed by a particular witness on whose testimony it can safely rely, without such or other corroboration. It has also to be borne in mind that the aspect of identification parade belongs to the stage of investigation, and there is no provision in the Code of Criminal Procedure which obliges the investigating agency to hold, or confers a right upon the accused to claim a test identification parade. Mere failure to hold a test identification parade would not make inadmissible the evidence of identification in court. What weight is to be attached to such identification is a matter for the courts of fact to examine. In appropriate cases, it may accept the evidence of identification even without insisting on corroboration……….”
