Illegality is generally a personal defense not available against holders in due course. Article 1409 of the Civil Code enumerates the contracts which are void, inexistent, and incapable of ratification. Among these is a contact with an illegal cause. Since such a contract is not merely voidable but is no contract at all, its illegality should normally be a real defense available even as against holders in due course. On the other hand, Section 55 of the NIL treats illegal consideration as a mere personal defense. Thus we have here a situation where although the contract lacks the essential element of a lawful cause or consideration, the law treats the defect as a defense available only as against holders not in due course. The Civil Code and the NIL are not inconsistent with each other because they deal with different situations. While the former specifies what contracts are void and inexistent, the latter in effect provides that though a negotiable instrument may have been issued or negotiated for an illegal consideration, only the parties involved in the illegality and subsequent parties who are not holders in due course can be adversely affected by such defect. Thus, although a gambling note may be unenforceable between the original parties by reason of illegal consideration, it is valid and enforceable in the hands of a holder in due course, who can recover its full amount against the maker.13 This is so not only because of Section 55 but also because Act 1757 provides that a promise to pay money lost at gambling is void, except as to a purchaser for value before maturity, in good faith and without notice. u
The defense of usury is merely personal and not real under Section 7 of the Usury Law which in part provides:
" ... And provided further, that 11othing herein contained shall be construed to prevent the purchase by an innocent purchaser of a negotiable mercantile paper usurious or otherwise, for valuable consideration before maturity when there has been no intention on the part of said purchaser to evade the provisions of this Act and said purchase was not part of the original usurious transaction. In any case, however, the maker of said note shall have the right to recover from said original holder the whole interest paid by him thereon and, in case of litigation, also the costs and such attorney's fees as may be allowed by the court." (Act 2655 as amended.)
A statute may however declare a contract void for all purposes, in which case the defense of illegality becomes real. 15
