You mentioned in the opening comments that typically the Federation Chamber is used for less contentious debates on government legislation. You also mentioned that from time to time more contentious debates could be conducted in the Federation Chamber, but that it is done with agreement from the opposition.
Is that a formal process whereby the official opposition agrees to a more contentious debate? What process or procedure is in place in terms of scheduling both the less contentious and also, more importantly, the more contentious debates? How is that agreement reached?
