They are putting their faith in a system of civil servants that want to serve the country and do their job, in comparison to those selected to break the system.
So then actually, yes the ruling was correct, and yes people are right to put this power back into the hands of congress, and out of the hands of civil servants.
Whatever terrible thing that someone would be complaining about in the future, it is mitigated by this correct ruling that helps stop that supposedly bad thing.
If you want to accept that position that I just laid out, then fine. You agree with me, but you would also be agreeing with the supreme court decision.
Therefore, when civil servants are put into place from the other side, they can't complain.
