Huh, it turns out you're right! Here's the relevant section for anyone interested:
So, did Milei just violate the Constitution with his DNU 366/2025? And are you saying that people should continue applying for citizenship at federal courts, despite what the DNU says? It also seems like the DNU may be null if I'm reading article 99, section 3 correctly?
So, naturalization and citizenship laws are the responsibility of the Congress (the legislature) according to article 75, section 12, and according to article 99, section 3, the President can't "emit provisions of a legislative character". The question I have now though, is who will declare the DNU null - the Supreme Court?
