Fifty-one years ago today, on May 9, 1974 (April 18, 1974 lunar calendar), Earl Warren, Chief Justice of the United States and Governor of California, passed away. Photo: Earl Warren Warren was born in Los Angeles, California in 1891 and died on July 9, 1974. His father was a Norwegian immigrant and his mother was a Swedish immigrant. He was a famous American politician and jurist. He served as the governor of California and the Chief Justice of the United States from 1953 to 1969. Justice Warren adhered to judicial activism, improved the constitutional status of the Supreme Court of the United States, and advanced the deep reform of the American constitutional system. For example, through the 1962 Bakerv. Carr case, the 1963 Grayv. Sanders case, and the 1964 Wesberryv. Sanders and Reynolds v. Sims case, he overturned the principle of "political thorns", clarified the content and judgment criteria of "political issues", established the jurisdiction of the judiciary over seat allocation cases and the election rule of "one person, one vote", and avoided social unrest caused by the unfair distribution of power. Justice Warren creatively interpreted the provisions of the Constitution and ushered in the Warren era of judicial reform in the US Supreme Court through a series of landmark rulings. For example, through Brown v. Boardof Edu-cation in 1954, he overturned the precedent of racial segregation but equality, abolished the segregation system in public schools, and finally ended the system of racial discrimination; through Mirandav. Arizona in 1966, he established the famous "Miranda Rule", which embodied the value of procedural justice, promoted the reform of the police system in the United States, and effectively guaranteed citizens' rights to silence and access to lawyers. The Warren Court set off one constitutional revolution after another, promoting various social movements in the United States in the 1950s and 1960s. On June 30, 1968, the new Chief Justice of the Supreme Court was inaugurated, and the Warren Court ended. America at this time is a beautiful landscape: laws that discriminate against blacks have fallen; blacks' civil rights have been progressively protected; school prayers are unconstitutional; districts have been redrawn according to the principle of "one person, one vote", and the distribution of congressional seats is no longer unfair; the domestic security program designed to limit communists has ended; obscenity is determined to be outside the framework of the First Amendment and unregulated; debate on public issues is unrestricted, vibrant and open; the Miranda Warning is born; the poor are granted the right to counsel; the Bill of Rights applies to the states... all this belongs to the "Almighty God who speaks from Washington" - the Warren Court.
