The democratic way would have been to submit the bill to increase the retirement age to vote. It wasn’t voted. It was imposed.
The bill to repeal the reform wasn’t passed not because representatives voted against it. That’s not how it works. It didn’t pass because it didn’t gain enough votes. Because you would HAVE to vote AGAINST the assembly, which is not the same as voting against a law.
Then again, it wasn’t done to keep the pension system as a whole. It was done to alleviate corporate social funding. The pension system wasn’t lacking.
Sorry for the lack of sources, I’m on mobile. If you want them I can search for them.
