The Judicial Branch of the United States was seemingly born independent, and judges have insisted their position is one bound by the constitution rather than explicit political ideology. The Supreme Court perhaps epitomizes this view most; though appointees are chosen by presidents, few actually identify as Republicans or Democrats. There has emerged the claim, particularly in recent years, that judicial independence is artifice, that legal beliefs are but a cover for one’s genuine agenda. A Supreme Court Chief Justice who faced early versions of such critiques was Chief Justice Earl Warren. Appointed by President Eisenhower in 1953, Warren’s sixteen-year tenure saw the Supreme Court enter a level of relevance perhaps unseen prior, with landmark cases like Brown v. Board of Education, Reynolds v. Sims, Miranda v. Arizona and Loving v. Virginia. Warren emerged as an unexpectedly progressive voice on the court, and his views earned him both praise and criticism. To what extent was he impartial, however? An analysis of his ideology and judicial philosophy remains relevant to the court today. 

The most common critique of Warren as Chief Justice was his supposed lack of guiding ideology. The journalist Antony Lewis once claimed Warren “made no attempt, in opinions or otherwise, to propose a consistent theory of how a judge interpreting the Constitution should approach his task,” despite agreeing with many of Warren’s positions. More critical was Justice John Marshall Harlan, who argued the Warren court “[forgot] the sense of judicial restraint” crucial to the operations of the Supreme Court. Though certainly influential, Harlan’s critiques of Warren were common at the time, and many opponents of the Chief Justice worried that the consequences of his judicial approach would be, as scholar George Edward White says, “to make the public fearful of tyrannical judges, expose the subjective dimensions of judicial decisionmaking, provoke resistance to Court decisions, and lower the Court’s public reputation.” A common criticism of Warren, therefore, is not that he held an incorrect philosophy; rather, some claimed he lacked a belief system at all. How true might these arguments have been in actuality? 

Later analyses of Chief Justice Warren’s judicial philosophy reveal a more consistent application of the law than many critics would assume. A 1955 essay of Warren’s reveals two major themes of his judicial outlook: the existence of the Bill of Rights as a means of protecting citizens from governmental overreach and the use of the Constitution as a living document in need of “constant and imaginative application” in response to new situations. In general, as White claims, “Warren’s [views] were consistent with an ethical perspective from which he viewed social issues, which he thought to be embodied in the Constitution, and which he believed to be basic to civilized life.” While not grounded in strict Constitutional theory as some of his other colleagues’ beliefs, Warren still possessed a consistent worldview on ethical values and citizen autonomy that guided many of his decisions. As judicial scholar Eugene Gressman wrote upon Warren’s passing, “[Warren] was not imposing … personal predilections and prejudices on a given case … he was selecting and choosing between competing constitutional or legal factors those that he deemed the most just or equitable.” In this sense, though his outlook was perhaps novel for his time, Warren’s judicial philosophy was as consistent and impartial as those of his peers. 

Perhaps the greatest proof in favor of Warren’s impartiality came from the Warren Commission formed in his name. Created to investigate the assassination of President Kennedy, the Commission was named after Warren after President Lyndon Johnson chose him to lead it, describing the Chief Justice as the “personification of fairness and justice in this country.” While it may be tempting to assume Johnson elected Warren to lead the Commission due to their generally similar ideology, the Commission arrived at a time that scholar Melissa Loewenstern says “the public was unsatisfied by the lack of tangible facts… the world began to believe almost anything,” meaning Warren’s leadership was necessary to restore public trust, as well. Warren even refused the appointment at first, referring to judicial independence, but was later convinced otherwise by Johnson thanks to an appeal to national duty. In his writings, Warren notes, “it is not in the spirit of constitutional separation of powers to have a member of the Supreme Court serve on a presidential commission,” demonstrating his actions stemmed from necessity rather than a rupture with his views of impartiality. 

What relevance might Chief Justice Warren’s philosophy have to the current United States outside of intriguing scholarship? What his career reveals is the ability to interpret the law through the lens of ethics and equity, of viewing the Constitution as a living document that – while embodying undeniable principles – must be interpreted and reinterpreted in new contexts. His novel views may have earned him ire from certain critics, but Chief Justice Warren was and remains one of the most trusted and respected jurists in American history. This faith of the citizenry stemmed largely from his consistent and impartial belief in their freedom and autonomy.
