As part of the legislative process, the subcommittee's role is to determine whether the bill is a votable item or not. A bill is designated a non-votable item if it does not meet one of the criteria, including being within federal jurisdiction and complying with the Canadian Charter of Rights and Freedoms. It must also determine whether it has already been voted on by the House of Commons or whether a similar matter is before the House. Those are the four criteria that should guide the committee in its review. The subcommittee is not supposed to be submitting or suggesting amendments to the bill. The only thing the subcommittee can do is decide whether or not a bill should be deemed a votable item.
