A vote is held, but not in the Chamber. Once the petition has been tabled, the Chamber does not decide whether a committee will examine it or not, even though that would be possible procedurally speaking. Practically, however, the committee meets and votes on whether it will examine the petition. According to our rules, a majority of the members from each parliamentary group must agree. So it is not just a majority decision. Let's say we had a majority government. It would not have the power to impose its decision; instead, it would need the consent of opposition members on the committee.
