France’s Constitutional Council on Wednesday rejected a second attempt by political opponents of French President Emmanuel Macron to hold a referendum against the pension reform promoted by the French government by raising the age limit from 62 to 64.

The council said in a statement that the proposed referendum did not meet the legal criteria as set out in the constitution, thus rejecting the holding of a referendum.

The council’s role was to decide whether the opposition’s request met the legal requirements for a referendum.

Since Emmanuel Macron bypassed parliament to push through the pension reform, opposition MPs have turned to the Constitutional Council twice in an attempt to derail it, but without success.

A first attempt had already been scrapped, partly because the pensions bill had not yet been passed and the proposed referendum would not have led to a change in the law.

Unions and the opposition have already planned a nationwide strike for June 6, two days before lawmakers debate an opposition proposal to repeal the pension law.
