@servelan Read up on the history of people and governments ignoring Supreme Court rulings.
Part of the checks and balances in the US system is that the Supreme Court, like all courts, get to issue their rulings, but they have no enforcement power.
The other branches, like everyone else, are free to ignore whatever papers come out of the Supreme Court, which is part of assuring that those lifetime appointments aren't so powerful that they become problematic.
The Supreme Court, like all courts, interpret law.
But they cannot force anyone else to listen to their interpretations.
Which is a good thing when it comes to cases that one might consider wrongly decided.
