Page 870 of Bosc and Gagnon states:
Supplementary estimates are deemed referred to the appropriate standing committees immediately after their tabling in the House. The supplementary estimates must be reported back, or are deemed to have been reported back, not later than three sitting days before the final sitting, or the last allotted day, of the supply period in which they were tabled.
Could you share why they were already deemed reported back and approved before the end of today?
