In 1782, Marshall won a seat in the Virginia House of Delegates, in which he served until 1789 and again from 1795 to 1796. The Virginia General Assembly elected him to serve on the Council of State later in the same year. In 1785, Marshall took up the additional office of Recorder of the Richmond City Hustings Court.  In 1788, Marshall was selected as a delegate to the Virginia convention responsible for ratifying or rejecting the United States Constitution, which had been proposed by the Philadelphia Convention a year earlier. Together with James Madison and Edmund Randolph, Marshall led the fight for ratification. He was especially active in defense of Article III, which provides for the Federal judiciary. His most prominent opponent at the ratification convention was Anti-Federalist leader Patrick Henry. Ultimately, the convention approved the Constitution by a vote of 89-79. Marshall identified with the new Federalist Party (which supported a strong national government and commercial interests), and opposed Jefferson's Republican Party (which advocated states' rights and idealized the yeoman farmer and the French Revolution).  Meanwhile, Marshall's private law practice continued to flourish. He successfully represented the heirs of Lord Fairfax in Hite v. Fairfax (1786), an important Virginia Supreme Court case involving a large tract of land in the Northern Neck of Virginia. In 1796, he appeared before the United States Supreme Court in another important case, Ware v. Hylton, a case involving the validity of a Virginia law providing for the confiscation of debts owed to British subjects. Marshall argued that the law was a legitimate exercise of the state's power; however, the Supreme Court ruled against him, holding that the Treaty of Paris in combination with the Supremacy Clause of the Constitution required the collection of such debts.  Henry Flanders in his biography of Marshall remarked that Marshall's argument in Ware v. Hylton "elicited great admiration at the time of its delivery, and enlarged the circle of his reputation." Flanders also wrote that the reader "cannot fail to be impressed with the vigor, rigorous analysis, and close reasoning that mark every sentence of it."  In 1795, Marshall declined Washington's offer of Attorney General of the United States and, in 1796, declined to serve as minister to France.
