Story joined the Court at a critical time, as it was just beginning to assert its Constitutional authority over state courts and state legislation. Chief Justice John Marshall led this effort, but Story had a very large share in the remarkable decisions and opinions issued from 1812 until 1832. From Story's early days on the Court he became one of Justice Marshall's strongest allies. Of the opinions issued at this time, Story wrote more than any justice but Marshall. Story's early jurisprudence mimicked that of the chief justice. The most significant of his early opinions were clearly those of Fairfax Devisee v. Hunter's Lessee and the subsequent Martin v. Hunter's Lessee. In Fairfax, the Court was forced to consider the constitutionality of the Confiscation Act, passed by the state of Virginia to take land from citizens who had sympathized with the British during the Revolution. This legislation ran contrary to terms of Jay's Treaty, negotiated in 1794, which provided that property was to return to the Tories. The Court, headed by Story, unanimously agree that the law was forced to give way before the terms of Jay's Treaty. This remained consistent with the larger body of the Marshall Court's work in which Story and Marshall sought to establish a strong federal Union.
