Mr. Chairman, there's a difference between a quorum to hear evidence from witnesses, which is what this is speaking to only, and a quorum to conduct business. This is the same as it was last time, and it's in other committees as well.
I understand Mr. Rathgeber's point, and it's a valid one, but I suspect that's why there's a difference here. The reduced quorum is only for the purposes of receiving evidence. I think that's why it's a relaxed standard.
