That's pretty much how it works; there's generally no way, in a modern parliamentary democracy to say "no, and also you can never discuss it again". You could put it in the constitution, but honestly there's a decent argument that parts of chat control would violate the EU's can't-believe-it's-not-a-constitution (the Lisbon Treaty is essentially a constitution, but is not referred to as such because it annoys nationalists) in any case and ultimately be struck down by the ECJ, like the Data Retention Directive was.
