Who is more powerful, DA or Judge?

A District Attorney (DA) often wields more practical power in shaping criminal case outcomes than a judge, as DAs decide whether to file charges, what charges to file, and influence plea bargains and sentences, while judges primarily ensure legal fairness and have final say on sentencing, though their discretion can be limited by mandatory minimums, shifting power to prosecutors. Judges oversee proceedings and rule on legal matters, but the vast majority of cases end in plea deals where the prosecutor's initial charging decisions and plea offers are paramount.

No, the President cannot directly change the number of Supreme Court Justices; only Congress has that power by passing a law, but the President must sign that law for it to take effect, meaning both branches must agree, as seen with the Judiciary Act of 1869 fixing the number at nine. While presidents appoint justices, they can only fill existing vacancies or new ones Congress creates, as the Constitution doesn't set the court's size, allowing Congress to adjust it as a legislative check.
