The Decision On February 24, 1803, the Court rendered a unanimous (4– 0) decision, that Marbury had the right to his commission but the court did not have the power to force Madison to deliver the commission. Chief Justice Marshall wrote the opinion of the court. Marshall presented the case as raising three distinct questions: Did Marbury have a right to the commission? Do the laws of the country give Marbury a legal remedy? Is asking the Supreme Court for a writ of mandamus the correct legal remedy?[2
