Writ of Mandamas
Article 3 - jurisdiction of law or equity
Bring a case showing Treason, Sedition of Subversion to SCOTUS showing illegal and unconstitutional use of Legislative branch to compel the House to nullify the illegal and unconstitutional articles passed by legislative resolution.
While the House has sole power to bring Impeachment (an indictment) and the Senate is the venue for trial and jurors, the Judicial Branch still has the judicial oversight.
As such, if due process was violated by the “prosecutor” or if the prima facie case is flawed or if there was prosecutorial misconduct, as in any criminal case, the SCOTUS would be the Constitutional body to provide the only remedy to undo an illegal impeachment thru a writ of mandamus.
The duty sought to be enforced must have two qualities: It must be a duty of public nature and the duty must be imperative and should not be discretionary.
SCOTUS could tell the House they have not met their Constitutional requirements and make them redo; or they could nullify the indictment if compelling evidence of criminal conduct was present in the legislative process of the House Impeachment.
This idea of “political” only is bullshit. The body is political but it does not in any way preclude the Constitutional requirements and precedent case law of due process or prosecutorial legal standards or judicial review and process of any other criminal proceeding.
This is unprecedented but very much supported in the Constitution and SC case history in terms of legal interpretation
