Well, I think a practice could develop, but technically that's not what it says.
The sentence reads, “That only the Clerk of the Committee be authorized to distribute documents, including motions, to the members of the Committee”. What it says at its narrowest is that only the clerk may distribute documents. It does not go on to say what gets distributed or under what circumstances.
I would actually insert a second clause right after that, obligating that all documents referred to the committee be distributed to all members, as a companion piece. I understand Colin's point. It sort of seems like it's understood, but when you read that first sentence, it's only an authorization clause, not really a directional clause.
The second one, of course, refers to the requirement that it be bilingual, that it be in both official languages.
