Why did William Marbury most likely support the Judiciary Act of 1789?

The Judiciary Act of 1789 created the federal court system and included a provision that Marbury’s lawyers believed let the Supreme Court issue a writ of mandamus in his case. That gave Marbury a way to ask the Court to order Secretary of State James Madison to deliver his commission. The act did not itself confirm Marbury’s appointment or declare Madison’s actions unconstitutional.
