This is, what, the fifth time in ten years they try to pass shit like this?
What really should be done is to disallow proposals, which are kinda the same. Once a mass surveillance proposal like this is defeated, it shouldn't be allowed to be constantly rebranded and reintroduced. We need a firewall in our legislative process that automatically rejects any future attempts at scanning private communications.
This very much exists in a lot of parliamentary rules authorities, but it's usually limited to once per "session." They just need to make rules that span sessions that raise the bar for introducing substantially similar legislation.
It can easily be argued that passing something that failed to pass before, multiple times, should require supermajorities. Or at least to create a type of vote where you can move that something "should not" be passed without a supermajority in the future.
It is difficult in most systems to make negative motions. At the least it would have to be tailored as an explicit prohibition on passing anything substantially similar to the motion in future sessions (without suspending the rules with a supermajority.)
I don't know as much about the French Parlement's procedure as I would like to, though.
