<P> One of the primary factors in Warren's leadership was his political background, having served two and a half terms as Governor of California (1943--1953) and experience as the Republican candidate for vice president in 1948 (as running mate of Thomas E. Dewey). Warren brought a strong belief in the remedial power of law . According to historian Bernard Schwartz, Warren's view of the law was pragmatic, seeing it as an instrument for obtaining equity and fairness . Schwartz argues that Warren's approach was most effective "when the political institutions had defaulted on their responsibility to try to address problems such as segregation and reapportionment and cases where the constitutional rights of defendants were abused ." </P> <P> A related component of Warren's leadership was his focus on broad ethical principles, rather than narrower interpretative structures . Describing the latter as "conventional reasoning patterns," Professor Mark Tushnet suggests Warren often disregarded these in groundbreaking cases such as Brown v. Board of Education, Reynolds v. Sims and Miranda v. Arizona, where such traditional sources of precedent were stacked against him . Tushnet suggests Warren's principles "were philosophical, political, and intuitive, not legal in the conventional technical sense ." </P> <P> Warren's leadership was characterized by remarkable consensus on the court, particularly in some of the most controversial cases . These included Brown v. Board of Education, Gideon v. Wainwright, and Cooper v. Aaron, which were unanimously decided, as well as Abington School District v. Schempp and Engel v. Vitale, each striking down religious recitations in schools with only one dissent . In an unusual action, the decision in Cooper was personally signed by all nine justices, with the three new members of the Court adding that they supported and would have joined the Court's decision in Brown v. Board . </P> <P> Fallon says that, "Some thrilled to the approach of the Warren Court . Many law professors were perplexed, often sympathetic to the Court's results but skeptical of the soundness of its constitutional reasoning . And some of course were horrified ." </P>
