of all circumstances, the non-presence of one or more independent persons at the relevant time would vitiate the trial or conviction. The obligation which Section 10(7) casts on the Food Inspector is to 'call' one or more persons to be present when he takes action. The facts in the instant case show that the Food Inspector did call the neighbouring shopkeepers to witness the taking of the sample but none was willing to co-operate. He could not certainly compel their presence. In such circumstances, the prosecution was relieved of its obligation to cite independent witnesses. In Babu Lal Hargovindas v. State of Gujarat, AIR 1971 SC 1277 it was held by this Court after noticing that Section 10(7) was amended in 1964, that non-compliance with it would not vitiate the trial and since the Food Inspector was not in the position of an accomplice his evidence alone, if believed, can sustain the conviction. The Court observed that this ought not to be understood as minimizing the need to comply with the salutary provision in Section 10(7) which was enacted as a safeguard against possible allegations of excesses or unfair practices by the Food Inspector.
