Any law in force before commencement of the Hindu Marriage Act, 1955:

Section 4(b): "any other law in force immediately before the commencement of this Act shall cease to have effect in so far as it is inconsistent with any of the provisions contained in this Act". Express repeal is not needed, but such a law survives where it is consistent with the Act; the wider "any matter" test applies to Hindu texts and customs under section 4(a).
