Final answer:
James Madison proposed the Council of Revision during the Constitutional Convention. The Council would have determined the constitutionality of laws after they were passed.
Step-by-step explanation:
During the Constitutional Convention, James Madison proposed the idea of a Council of Revision.
According to Madison's proposal, the Council of Revision would have initially made a consequential decision about whether a law was constitutional.
The determination would have occurred after the law was passed, as Madison believed that the Council's role would be to review laws and veto them if they were found to be unconstitutional.
