“9. In order to determine the question whether offence punishable under Section 138 of the Act is made out against the appellant, it will be necessary to examine the scope and ambit of presumptions to be raised as envisaged by the provisions of Sections 118 and 139 of the Act. In a suit to enforce a simple contract, the plaintiff has to aver in his pleading that it was made for good consideration and must substantiate it by evidence. But to this rule, the negotiable instruments are an exception. In a significant departure from the general rule applicable to contracts, Section 118 of the Act provides certain presumptions to be raised. This Section lays down some special rules of evidence relating to presumptions. The reason for these presumptions is that, negotiable instrument passes from hand to hand on endorsement and it would make trading very difficult and negotiability of the instrument impossible, unless certain presumptions are made. The presumption, therefore, is a matter of principle to facilitate negotiability as well as trade. Section 118 of the Act provides presumptions to be raised until the contrary is proved (i) as to consideration, (ii) as to date of instrument, (iii) as to time of acceptance, (iv) as to time of transfer, (v) as to order of endorsements,(vi) as to appropriate stamp and (vii) as to holder being a holder in due course. Section 139 of the Act provides that it shall be presumed, unless the contrary is proved, that the holder of a cheque received the cheque of the nature referred to in Section 138 for the discharge, in whole or in part, of any debt or other liability.

Under the Indian Evidence Act all presumptions must come under one or the other class of the three classes mentioned in the Act, namely, (1) "may presume" (rebuttable), (2) "shall presume" (rebuttable) and (3) "conclusive
