The USSC seems pretty lazy in these days of ever increasing litigation against the Federal Government bureaucracy and Trump EOs.
The need to double their output or get the lesser courts to halve their’s.
As it is, the USSC only takes 1% - 2% of the cases appealed to it each year (this particular case was one of the others), and they are still bogged down. I’m not sure if 9 Justices is enough, even with all of their staff, to handle the cases that come from 325 million people and the businesses associated with them.
I wouldn’t mind it if Trump would be given the authority to name, say, 10 more Justices so that there’d be 19. :>) Short of that, we’re kind of stuck with the present system.
