The House of Lords in the Sussex Peerage Case12 in which Tindal LCJ said:
The only rule for the construction of Acts of Parliament is, that they should be construed according to the intent of the Parliament which passed the Act. If the words of the Statute are in themselves precise and unambiguous, then no more can be necessary than to expound those words in their natural and ordinary sense.
Similarly, in Tasmania v Commonwealth O’Connor J said
I do not think it can be too strongly stated that our duty in interpreting a Statute is to declare and administer the law according to the intention expressed in the Statute itself. In this respect the Constitution differs in no way from any Statute of the Commonwealth or of a State.
