Of course, we'd need to hear from the librarian, but I'm not sure of the exact date you mentioned that the motion was passed. It speaks to the 39th Parliament, and if it were late in the session, that might perhaps be a reason.
I would respectfully suggest, if the intent is to let the sun shine in, that we might fall into a similar situation by just referencing the motion for the current session of Parliament. If a friendly amendment were considered, it would be that we not reference just one particular session, but that going forward this be the policy for all sessions of Parliament. That would then limit us strictly to what we have left going forward.
