(1)Fundamental provisions are provisions of this Act (and provisions which are fundamental provisions by virtue of section 22(1)(a)) that are incorporated as terms of occupation contracts or particular kinds or descriptions of occupation contract (subject to sections 20(1) and (2) and 21).
(2)Each provision of this Act that is a fundamental provision identifies itself as such, and specifies the occupation contracts into which it is incorporated as a fundamental term.
(3)Nothing in this Act is to be read as enabling a landlord or contract-holder to do anything which would have the effect that a fundamental provision which is applicable to the occupation contract is not, or is not to be treated as, a fundamental provision which is applicable to the contract (but this does not prevent an agreement to modify or not to incorporate a fundamental provision, or a variation of a fundamental term, which is in accordance with this Act).
