Yes 🙂
So, we have the Treaties. I guess it is this: https://eur-lex.europa.eu/collection/eu-law/treaties/treaties-force.html .
So, what the Treaties say about the EUCO declarations and about the conclusions? Or more generally, how the Treaties set the legislative processes and decision making and the roles of the bodies?
Should I study the Treaties or is there a concise and accessible description at the level for, say, students of a secondary school?
