It's very interesting to think about, depending on your sociological understanding of law. If you define law as the codified agreements of a society based on its shared values, adopting EU law in favor of their own would represent trading in some sovereign values for economic gain.
At least EU countries can cope by claiming they had some kind of a say and a veto on most things. EU prospects don't have this rationalization.
- Friend of mine is Albanian
- Albania wants to join the European Union
- They are required to ensure that their laws don't have "internal conflicts" e.g. one law says something is legal, a different law says it's illegal
- Reviewing by hand would take a lot of work
- Friend uses an LLM to analyze the Albanian laws and find any of these conflicts
Apparently it worked out pretty well
