72. No collective agreement shall take effect until the filing at the office of the labour commissioner general of five exemplars or copies, true to the original, of such collective agreement and of a true copy of its schedules. The same rule applies to any amendment subsequently made to such collective agreement.
Such filing has retroactive effect to the date provided in the collective agreement for its coming into force or, failing such date, to the date of the signing of the collective agreement.
Failing such filing within sixty days of the signing of the collective agreement or of any amendment thereto, the right to certification shall thereupon be acquired by any other association, with respect to the group of employees for whom such collective agreement or such amendments have been made, provided that such other association applies therefor after the expiry of such sixty days but before such filing has been effected, and provided that certification is subsequently granted to it.
The party so filing must indicate the number of employees governed by the collective agreement and comply with the other regulatory provisions established to that effect under section 138.
