If people they don't like the laws they've committed themselves to, they can choose not to follow them anymore. However, the advantages they receive in return, in this case the freedoms and economic benefits of being in the EU, will also disappear if they decide to play by their own rules. With the massive benefits Poland has gotten from the EU, I don't think it's in their interest to leave, especially since it doesn't have the negotiating power the UK had (and Brexit has been a series of catastrophes nonetheless).
Nobody is forcing these people to follow foreign laws, it's just that they want the benefits without doing anything in return. The EU is not just a trade bloc, it's an institution to create a shared European ideal. They may not like the deal, but they're free to refuse it and negotiate a better one.
This is either not true or impossible to tell because Polish constitution was really poorly written with very many issues being delegated to lower acts. The Constitutional Tribunal gets to freely decide what is or isn't against the constitution and current Tribunal judges are favourable to the gov.
It's as if the US constitution was stitched from multiple Commerce Clauses. The SCOTUS could rewrite it on the fly (they already do to some extent).
They're written by the politicians who were voted into power and who have certain vested interests in voting them. They were not voted by a population, sorry.
Yeah, then you will all become yanks with government in Washington you can't vote for (why are we suddenly talking about the UN?)
Hopefully the UN gets enough funding to occupy the roles of state and municipal police soon. Then we can free the common man from the tyranny of local government.
