8. In the light of these conflicting versions and suspicious features on this crucial aspect, the plea of the accused that the notes were put in the drawer without his knowledge, does not appear to be improbable. In any event, PW 1 ‘s evidence for the abovesaid reasons, does not appear to be wholly reliable. It is in this context the courts have cautioned that as a rule of prudence, some corroboration is necessary. In all such type of cases of bribery, two aspects are important. Firstly, there must be a demand and secondly there must be acceptance in the sense that the accused has obtained the illegal gratification. Mere demand by itself is not sufficient to establish the offence. Therefore, the other aspect, namely, acceptance is very important and when the accused has come forward with a plea that the currency notes were put in the drawer without his knowledge, then there must be clinching evidence to show that it was with the tacit approval of the accused that the money had been put in the drawer as an illegal gratification. Unfortunately, on this aspect in the present case we have no other evidence except that of PW1. Since PW1’s evidence suffers from infirmities, we sought to find some corroboration but in vain. There is no other witness or any other circumstance which supports the evidence of PW1 that this tainted money as a bribe was put in the drawer, as directed by the accused. Unless we are satisfied on this aspect, it is difficult to hold that the accused tacitly accepted the illegal gratification or obtained the same within the meaning of Section 5(1)(d) of the Act, particularly when the version of the accused appears to be probable.
