In the past, when the finance committee was dealing with the budget implementation bill, it would, during the course of its study, write to other committees to invite them to study the subject matter of specific clauses related to their mandate and submit to the finance committee proposed amendments, to be deemed moved during the clause-by-clause study of the bill at the finance committee.
Since the clause-by-clause study is planned for the 28th, that would leave only next week for other standing committees to take a look at those clauses. The schedule might be tight, but if the committee wants to propose a motion to invite other committees to take a look at specific clauses and to submit proposals for amendments or give their opinion on them, that's at the discretion of this committee.
