We can't accept petitions about appointments, which includes calling for a vote of no confidence.

We used to accept petitions that called for a vote of no confidence. However, the Petitions Committee can’t schedule votes of no confidence. This was often frustrating and disappointing for petitioners.

Petitions calling for action on policy are more likely to be an effective way of achieving the change you want.
