judicial oath of office on October 4, 1965. His appointment ensured the continuation of the Warren Court's liberal majority. The seat Fortas occupied on the Court had come to be informally known as the "Jewish seat," as his three immediate predecessors—Goldberg, plus Felix Frankfurter and Benjamin Cardozo before him—were also Jewish. Fortas continued to serve as an adviser to Johnson after becoming an associate justice. He attended White House staff meetings, advising the president on judicial nominations and discussed private Supreme Court deliberations with him. In 1966, he substantially edited an initial version of Johnson's State of the Union Address. In 1968, Fortas wrote a book called Concerning Dissent and Civil Disobedience. Fortas's law clerks included former Under Secretary of Defense for Policy Walter B. Slocombe and Martha A. Field, a scholar of constitutional law, family law, and bioethics.

Fortas clashed with his fellow Associate Justice Hugo Black during much of his time on the Court.

In 1968, a Warren clerk called their feud "one of the most basic animosities of the Court". Fortas's best relationship was with William O. Douglas, his former law professor at Yale. Fortas was also close to Associate Justice William J. Brennan and Chief Justice Earl Warren. Brennan's offices were in the chambers next to those of Fortas. Fortas's wife recalled that Fortas "loved Warren". Fortas called John Marshall Harlan II "one of my dearest friends, although we usually are on opposite sides of the issues here." In 1967, Fortas and Douglas dissented in the 5–4 decision Fortson v. Morris, which cleared the path for the Georgia State Legislature to choose the Governor of Georgia in the deadlocked Georgia gubernatorial election of 1966 between the Democrat Lester Maddox and the Republican Howard Callaway. Fortas said that the State Constitution of 1824, allowing the legislature to choose the governor if no one wins a majority in the general election, was at odds with the equal
