There should be no periods of less than 60 and 30 days. That's what I believe.
And the time limit for submitting a brief should be 60 days. When you receive 212 briefs, you can't go through them all in a day. Each of the briefs has to be read by each commission member, and the members have to comment on them together. This isn't a decision that is made individually. Three people sit on the commission and three people decide. If there's ever a conflict, there is always the option of appealing to a judge. I believe that people have to agree.
That's why a commission is established. At the Federal Electoral Boundaries Commission for Quebec, the three members agreed on every action that was taken. So when we decided to take a particular riding and do something with it, the three members were in agreement. They had considered the matter. Each one had done his research separately. Each one had a document on the history of the riding to determine exactly what he thought, in addition to the briefs.
Furthermore, the members had an excellent secretary, who moreover was subsequently hired by Elections Canada.
