One of the peculiarities of the US is that the supreme court can reject laws as unconstitutional. I have always thought that that is a bad idea. It gives citizen less influence on politics, it makes it more difficult for politicians to rule the country as their laws can unexpected be revoked by some court and it invites politicians to rule "over their grave" by appointing judges who share their political opinions.
This lawyers are advancing in the EU too. For a long time already national governments have seen their laws subject to the European Court of Human Rights. And now the EU itself is becoming subject to it too. I don't think this is a good development.
