Considerable stress has been laid by Mr. Anthony upon the fact that, besides the four eye witnesses who have been examined in tllis tase, the occurrence, according to the first information report, had also been witnessed by Baddal, Shankar and Hubba. These persons were, however, not examined as \Vitnesses at the trial. It is also pointed out that in addition to these persons, the occurrence was also witnessed by Sham Lal and Hubba (this Hubba is different frmR Hubba whose name was mentioned in the first information report), who also arrived at the scene of occurrence· Sham Lal and Hubba too were not examinec\ as witnesses. . The non-examination of these witnesses, in our opinion, would not introduce an infirmity fatal to the prosecutioa case. It is no doubt true that the prosecution is bound to produce witnesses who are essential to the unfolding of the nar· rative on which the prosecution is' based. Apart from that, it cannot be laid down as a rule that if a large number of persons are present at the time of the occurrence, the prosecution is bound to call and examine each and every one of those persons. The answer to the question as to what is the effect of the non-examination of a particular witness would de· nd upon the facts and circumstances of each case. In case enough number of witnesses have been examined with (egard to the actual occurrence and their evidence is reliable and sufficient to base the conviction of ihe accused thereon, the prosecution may well decide to refrain from examining the either witnesses. Likewise, if any of the witnesses is won over by the accused party and as such is not likely to state the truth, the prosecution would have a valid groun,d for not examining him in court. The prosecution would not, however be justified in not examining a witness on the ground that his evidence even though not untrue would go in favour of the accused. It is as much the duty of prosecutor as of the court to ensure that full and material facts are brought on the record so that there may be no m;<carriage of justice. The discharge of such a duty cannot be affected bv the consideration that some of the facts if brouht on the record would be favourable to the accused. In case the court finds that the prosecution has not examined witnesses
