Allow me to explain my position to the parliamentary secretary. I attended the meetings of the subcommittee on agenda and procedure last year and the subcommittee never held a vote. We always operated by consensus. If a vote is necessary, the matter is referred back to the main committee which ultimately has decision-making authority.
I for one enjoyed having the parliamentary secretary in attendance, because he served as a go-between between the government and the committee and let us know, for example, what we could expect from an upcoming bill. A good example of the benefits of his presence was that generally speaking, the committee would ask the parliamentary secretary about the minister's availability to testify.
I don't recall the subcommittee having to hold a vote. It always operated by consensus. That's why we liked to have the parliamentary secretary around, because he was not entitled to vote. If, for whatever reason, a vote was required, then the other four members voted.
