The French government would use an unique constitutional procedure to get its unpopular pension reform measure through the National Assembly without a vote, according to a government source quoted by Reuters on Thursday.

A request for comment from the government received no immediate response.

The move, using the so-called article 49.3 of the constitution, will ensure the bill raising the retirement age by two years to 64 is adopted, but it shows President Emmanuel Macron and his government failed to garner enough of a majority in parliament.

Resorting to the measure is likely to further enrage unions, protestors and left-wing opposition parties that say that pension overhaul is unfair and unnecessary.

“This government is not worthy of our Fifth Republic, of French democracy. Until the very end, parliament has been ridiculed, humiliated,” Fabien Roussel, head of the French Communist Party said.

Socialist Party head Olivier Faure told Reuters earlier on Thursday that such a move could unleash “an uncontrollable anger” after weeks of rolling strikes and protests.

Opposition parties are likely to request a vote of no confidence in the government, however that is unlikely to pass as most conservative lawmakers would likely back the government.

Macron and his government say that the raising the retirement age is necessary to get the pension system out of the red by the end of the decade.

His failure to get the pension overhaul passed by a majority in parliament is not only a serious blow to his reformist credentials, but it risks destroying much of his political capital for the rest of his second mandate, which runs until 2027.
