Summary: written with AI from the case record.

What it's about

O’Connor calls the alleged practice pervasive; that is his claim, not a finding by the Supreme Court.

Question presented

Should this Court invoke its extraordinary power of supervisory control to halt a pervasive and indefensible practice by both Article I Tax Court judges and Article III federal judges in tax cases of routinely branding constitutional challenges as frivolous?

What happens next

The Court must decide whether to hear the petition. No oral argument or decision date is set; oral argument can be scheduled only if the Court agrees to hear the case.
