Expressions in subordinate legislation have the same meanings in the Interpretation Act 1978, unless the contrary intention appears (Section 11).
(1) In a law of the Commonwealth or a Territory Ordinance, unless the contrary intention appears:
All the rules above are subject to any contrary intention being expressed by the testator.
However, Article 22P states that the President may grant pardons "on the advice of the Cabinet", which indicates a contrary intention.
It is a rule of statutory interpretation that unless a contrary intention appears, the word "person" includes any body of persons corporate or unincorporated.
Unless the contrary intention appears, property bought with money belonging to the firm is deemed to have been bought on account of the firm.
A will speaks from the death of the testator, unless a contrary intention appear.
However, in many instances such implied terms can be displaced by the contrary intention appearing in the contract between the parties.
Moreover, there are no indications that Congress had a contrary intention.
For the reasons I have stated above, a contrary intention does appear from the subject and the purpose of the provisions.
