alt Hacker NewsIt seems to me that "no and don't ask again" should be a possible outcome of a vote on proposed legislation.
Without going into full detail on the procedure I'm imagining, such an outcome would bar consideration of equivalent legislation for several years and require a supermajority at several stages of the legislative process to override.
The EU parliament is not a real parliament since it can't choose which laws it has to vote for, and in negociations ("trilogue") it doesn't hold the pen.
Basically, it can oppose new legislations but can't retract old laws.
