Mr. Chair, the issue of precedent primarily arises in terms of House business in relation to rulings by the Speaker. It is always an argument that something happened a certain way once upon a time and that should be taken as a precedent, but that's a matter of debate.
To my knowledge, there is no binding rule about precedent based on a particular practice or action taken by a committee or a House at one point that binds a subsequent House, or the same committee at a subsequent time, in looking at a similar situation. They might or might not choose to follow the previous actions.
