We were just talking about judicial interpretation of words stated in legislation today in Law
Apparently you would first enquire about the whole purpose/intention of legislating the
Freedom of Information Act 1989(NSW). This is given authority by (s) 33 of the
Interpretation Act 1987 (NSW). The section was constructed to promote the purpose or object underlying an Act, whether expressly stated or not when interpreting meanings of words.
You would also go out of your way to find materials that supported a definition of the specific word pursuant to (s) 34 of the same Act above. This gives provisions for consideration of any other authorised material to assist in the ascertainment of the provision. Authorised materials include parliamentary reports, dictionaries
p), and meanings of the same word from other legislation. (not an definite list)
This would be only a broad idea of how you would start interpreting ambiguouis/broad terms within legislation .
As for the words "relating to dealing"- that would be an exhaustive list....LoLz
NOTE: I only just left the law seminar and my understanding is not perfect
EDIT: what other ways are there of accessing such information?
