Ravi alias Ravichandran Vs State represented by Inspector of Police (2007) 15 SCC 372

Hon'ble Supreme Court of India observed as -
“A judgment of conviction can be arrived at even if no test identification parade has been held. But when a first information report has been lodged against unknown persons, a test identification parade in terms of Section 9 of the Evidence Act, is held for the purpose of testing the veracity of the witness in regard to his capability of identifying persons who were unknown to him....
It was incumbent upon the prosecution to arrange a test identification parade. Such test identification parade was required to be held as early as possible so as to exclude the possibility of the accused being identified either at the police station or at some other place by the witnesses concerned or with reference to the photographs published in the newspaper. A conviction should not be based on a vague identification.”

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……….”

Pramod Mandal Vs State of Bihar (2004) 13 SCC 150

Hon’ble Supreme Court of India observed as under "It is neither possible nor prudent to lay down any invariable rule as to the period within which a test identification parade must be held, or the number of witnesses who must correctly identify the accused, to sustain his conviction. These matters must be left to the courts of fact to decide in the facts and circumstances of each case. If a rule is laid down prescribing a period within which the test identification parade must be held, it would only benefit the professional criminals in whose cases the arrests are delayed as the police have no clear clue about their identity, they being persons unknown to the victims. They, therefore, have only to avoid their arrest for the prescribed period to avoid conviction. Similarly, there may be offences which by their very nature may be witnessed by a single witness, such as rape. The offender may be unknown to the victim and the case depends solely on the identification by the victim, who is otherwise found to be truthful and reliable. What justification can be pleaded to contend that such cases must necessarily result in acquittal because of there being only one identifying witness? Prudence therefore demands that these matters must be left to the wisdom of the courts of fact which must consider all aspects of the matter in the light of the evidence on record before pronouncing upon the acceptability or rejection of such identification.

Md Kalam @ Abdul Kalam Vs State Of Rajasthan on 14 March 2008

Hon’ble Supreme Court of India observed as under "it was contended that there was possibility of the appellant having been shown to the complainant and his wife. It was stated that the Test Identification Parade  was done after a period of over 7 days...

 As was observed by this Court in Matru v. State of U.P. (1971 (2) SCC 75) identification tests do not constitute substantive evidence. They are primarily meant for the purpose of helping the investigating agency with an assurance that their progress with the investigation into the offence is proceeding on the right lines. The identification can only be used as corroborative of the statement in court. The necessity for holding an identification parade can arise only when the accused are not previously known to the witnesses. The whole idea of a test identification parade is that witnesses who claim to have seen the culprits at the time of occurrence are to identify them from the midst of other persons without any aid or any other source. The test is done to check upon their veracity. In other words, the main object of holding an identification parade, during the investigation stage, is to test the memory of the witnesses based upon first impression and also to enable the prosecution to decide whether all or any of them could be cited as eyewitnesses of the crime. The identification proceedings are in the nature of tests and significantly, therefore, there is no provision for it in the Code and the Evidence Act. It is desirable that a test identification parade should be conducted as soon as after the arrest of the accused. This becomes necessary to eliminate the possibility of the accused being shown to the witnesses prior to the test identification parade. This is a very common plea of the accused and, therefore, the prosecution has to be cautious to ensure that there is no scope for making such allegation. If, however, circumstances are beyond control and there is some delay, it cannot be said to be fatal to the prosecution.

As a general rule, the substantive evidence of a witness is the statement made in Court. The evidence of mere identification of the 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, therefore, is to test and strengthen the trustworthiness of that evidence. It is accordingly considered a safe rule of prudence to generally look for corroboration of the sworn testimony of witnesses in Court as to 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. The identification parades belong to the stage of investigation, and there is no provision in the Code which obliges the investigating agency to hold or confers a right upon the accused to claim, a test identification parade. They do not constitute substantive evidence and these parades are essentially governed by Section 162 of the Code. Failure to hold a test identification parade would not make inadmissible the evidence of identification in Court. The weight to be attached to such identification should be a matter for the Courts of fact. In appropriate cases it may accept the evidence of identification even without insisting on corroboration.

It is no doubt true that much evidentiary value cannot be attached to the identification of the accused in Court where identifying witness is a total stranger who had just a fleeting glimpse of the person identified or who had no particular reason to remember the person concerned, if the identification is made for the first time in Court....

conviction is accordingly maintained.

Munshi Singh Gautam vs. State of M.P. (2005) 9 SCC 631

Hon'ble court observed,“ As was observed by this Court in Matru vs. State of U.P. 1971 2 SCC 75 identification tests do not constitute substantive evidence. They are primarily meant for the purpose of helping the investigating agency with an assurance that their progress with the investigation into the offence is proceeding on the right lines. The identification can only be used as corroborative of the statement in Court. (See Santokh Singh vs. Izhar Hussain 1973 2 SCC 406.) The necessity for holding an identification parade can arise only when the accused are not previously known to the witnesses…
