I would see it as a place for emergency and take-note debates, PMBs, petitions and privilege debates, which could go as long as they wanted to, with the primary chamber only being government legislation, opposition days and all of the votes. That's the structure I'd see, but having a joint secondary committee.... If PMBs go there, then that whole huge delay of PMBs at the Senate may be fixable as well.
You were the Senate Clerk for a long time.
