when do us marshals get involved in a case
United States Marshals Service The Marshals Service is the primary agency for fugitive operations, the protection of officers of the Federal Judiciary, the management of criminal assets, the operation of the United States Federal Witness Protection Program and the Justice Prisoner and Alien Transportation System, and execution of federal arrest warrants. Throughout its history, the Marshals have also provided unique security and enforcement services including protecting African-American students enrolling in the South during the civil rights movement, escort security for United States Air Force LGM-30 Minuteman missile convoys, law enforcement for the United States Antarctic Program, and protection of the Strategic National Stockpile.[5]
Procedures of the Supreme Court of the United States The votes of four Justices at Conference (see Rule of four) will suffice to grant certiorari and place the case on the court's calendar. If the Supreme Court grants certiorari (or the certified question or other extraordinary writ), then a briefing schedule is arranged for the parties to submit their briefs in favor of or against a particular form of relief. During this time, an individual or group having an interest in a case but not a party to the case may submit a motion to appear before the court as amicus curiae ("friend of the court"). Except for certain specific categories (such as lawyers for state and local governments) or where all parties to the case consent, it is in the Court's discretion whether such motions are granted.
