Someone correct me if I’m wrong, but those pesky fed judges are not employees. I believe they are appointees. Now those that staff the fed courts are likely employees, and not having those rascals around might impede the leftist judges operations. But good lefty employees will volunteer their time just to obstruct Trump, then wind up being paid overtime when it’s all over.
IMO, not a good idea.
Electricity for Federal courts is not essential. The founders wrote The Constitution by candlelight, with quill pens, in non air conditioned buildings.
