He also designed the university's seal, which is still used by the school. In 1874, in a district court case, Deady ruled in favor of Marcus Neff in a lawsuit against Sylvester Pennoyer concerning unpaid legal fees to John H. Mitchell and a sheriff's auction of Neff's land to Pennoyer. The case became the landmark U.S. Supreme Court decision of Pennoyer v. Neff that helped define the law of personal jurisdiction. In 1885, Deady admitted Mary Leonard to the federal bar, the first woman admitted to practice in Oregon, though the Oregon Supreme Court at first denied her admittance to the state bar on technical grounds. Later that year the Oregon legislature resolved the technical issue in the statute and the state high court admitted Leonard into the state bar. Among Deady's work is the General Laws of Oregon, which he compiled and annotated in 1866. This work consisted of a Code of Civil Procedure, a Penal Code, and a Code of Criminal Procedure. In this role he not only codified existing laws, but also made new laws. Deady often drafted the legislation that led to state statutes, thus playing a crucial role in the lawmaking process in the state of Oregon between 1859 and 1872. In 1874, Deady and fellow code commissioner and later U.S. Representative Lafayette Lane updated Deady's earlier compilation of the state's laws. His criminal laws remained largely in effect in Oregon until the legislature revised much of those laws in 1971. Deady also was the author of the state's business incorporation act. The act was the first in the country to place all business corporations on the same level by requiring a minimum of three people to incorporate as a business. Regarding Deady's contributions to Oregon, former Oregon Supreme Court justice and United States Attorney General George Henry Williams said: "No hand has been so strongly and deeply impressed upon the legislative and judicial history of Oregon as that of Judge Deady." Later years, death, and legacy As a prominent figure in Portland he continually worked to raise funds for the library he supported. He also relied on financial help from his associates in order to supplement his small salary as a federal judge. This allowed him to keep his personal appearance inline with what was expected of prominent citizens. In contravention to his earlier stances during the Oregon Constitutional Convention, Deady later denounced violence
