"Problematic" is too vague a term here. Do you mean "impeachable offense", or "something a group of people think is a problem"? If literally all or even > 50%

"Problematic" is too vague a term here. Do you mean "impeachable offense", or "something a group of people think is a problem"? If literally all or even > 50% of a district court judge's rulings were reversed on appeal, would they face sanction? I've never heard of this happening so I don't really know. But I have never heard of there being a process for it. I am curious what process folks think there should be?
