I think Mr. Harris' comment is very relevant. That said, we can choose to meet even if the budget speech is scheduled a few hours earlier. Presumably it will start at 4:00 p.m. and be over by 6:30 p.m.
Will the committee members want to meet anyway? I think that needs to be asked. It's still possible to do so.
I don't have any particular view on the matter, but we have to accept that it could be a problem.
