In this part, it says: “For greater certainty, nothing in this Act, by specific mention or omission [...]”. I understand that. Basically, no clause can interfere with the powers of Parliament. When it says “by specific [...] omission”, that is very broad. That means even with respect to something that is not included in the legislation.
Do you have any examples of an omission that could have an impact on a decision by Parliament? Under other agreements, has this question arisen in the past because of omissions in the bill?
