30.1. No provision of a supplemental plan may have the effect of preventing the payment of the retirement pension to an employee before he attains the age of 65 years or of reducing the pension owing to the fact that the employee receives the retirement pension payable under the Act respecting the Québec Pension Plan (chapter R-9) or an equivalent plan or that he qualifies therefor.
Notwithstanding the foregoing, if an employee under the age of 65 years applies therefor, his pension may be reduced owing to the fact that he receives the retirement pension payable under the Act respecting the Québec Pension Plan or an equivalent plan or that he qualifies therefor provided that the reduction does not lessen the value of the pension payable under the supplemental plan.
