On April 25, 1885, the UC Hastings board of directors convened to appoint Perrie Kewen as the new registrar, because the previous registrar had died. At the request of Serranus Clinton Hastings, Attorney General Edward C. Marshall challenged Kewen's appointment by initiating a proceeding for a writ of "quo warranto" in San Francisco County Superior Court. On March 30, 1886, in what became known as "Kewen's Case", the Supreme Court of California upheld Kewen’s appointment by declaring the 1883 and 1885 acts to be unconstitutional on the basis of a provision of the 1879 state constitution guaranteeing the legislative independence of the University of California. In other words, the 1879 ratification of the state's second constitution (which remains in effect today) effectively stripped the California State Legislature of the power to amend preexisting statutes governing the University of California, including the 1878 act. This was the last time that Serranus Clinton Hastings would try to shape the future of the law school that he had founded; UC Hastings has maintained its hard-fought independence from the Regents ever since. The irony of "Kewen's Case" is that a constitutional provision intended to protect the University of California was applied in such a way as to prevent the University from taking control of its first law school.In contrast, the "Affiliated Colleges"—the medical, dental, nursing, and pharmacy schools in San Francisco—were affiliated with UC through written agreements, and not statutes invested with constitutional importance by court decisions. In the early 20th century, the Affiliated Colleges agreed to voluntarily submit to the Regents' governance during the term of UC President Benjamin Ide Wheeler, as the Board of Regents had come to recognize the problems inherent in the existence of independent entities that shared the UC brand but over which UC had no real control. While UC Hastings remained independent, the Affiliated Colleges began to increasingly coordinate with each other and the rest of the UC bureaucracy under the supervision of the UC President and the Regents, and evolved into the health sciences campus known today as the University of California, San Francisco.In 1900, UC Hastings became one of 27 charter members of the Association of American Law Schools (AALS).
