If the ruling makes no legal sense and is just to disagree with him on political grounds, then I could see it as a reason for possible impeachment.
Judges, in my opinion, should be making sound legal judgements based on current law and precedent. If that's not the reasoning they used to come to their judgment, then they aren't doing their job, and that should be grounds for impeachment or whatever review process judges go through.
Do you agree with my general opinion?
