Thank you, Mr. Chair.
There's no standing order that governs dissenting or supplementary opinions. The practice has been that after the committee has adopted a substantive report, there's a motion, or the party that wants to append this supplementary dissenting opinion seeks support of the committee, either by way of a motion or just by seeking the consent of the committee to append that report. Then it's up to the committee to allow that or not. The the committee has often decided length and deadlines in terms of when that party has to submit its dissenting or supplementary opinion.
In the case of the oil sands, for instance, that's what happened.
