The system is clearly broken. Everyone can sue in any district and get judgements that change laws for the whole country. There is no clear delineation in terms of who can do what. To the extent that there are clear mandates (DACA and immigration being obvious examples) they are ignored by judges without consequence (When was the law judge to be impeached by the Congress?). Yup, the system is definitely broken
There have been 18 impeachments of fedjudges, 11 convictions and 4 resignations. In 228 years and tens of thousands of judges appointed this pitiful number shows that no job is more secure than a federal judge.
