An apprenticeship route into law

Jackson grew up in western New York, attended Albany Law School for a year and continued his training in a law office. He entered the New York bar in 1913 without graduating from law school.

His career began in local practice, not immediately in Washington. That background matters when reading the later public image of an eloquent national advocate: it preceded, rather than resulted from, federal appointment.

Successive offices, different responsibilities

The Federal Judicial Center records his private practice in Jamestown and Buffalo, Treasury work from 1934 and successive Justice Department positions. He served as solicitor general from 1938 to 1940, attorney general from 1940 to 1941 and then joined the Supreme Court.

Those offices did not give him the same task. An advocate represents the government’s position; an attorney general leads its legal department; a justice decides cases with other members of a court.

Liberty and wartime state power

Jackson wrote the Court’s 1943 opinion rejecting compelled public-school flag salutes in Barnette. He also dissented in Korematsu in 1944, objecting to judicial approval of the exclusion imposed on Japanese Americans.

A majority opinion and a dissent have different authority. Putting both under the heading “Jackson’s rulings” would obscure whether his argument represented the Court’s result or his opposition to it.

Prosecution at Nuremberg

President Harry Truman appointed Jackson to lead the U.S. prosecution of major Nazi war criminals. He undertook that work while a Supreme Court justice; the Federal Judicial Center dates his prosecutorial service to 1945–1946.

He then continued his judicial career until his death in 1954. The two roles invite comparison, but an international prosecution should not be read as another domestic Supreme Court opinion. The linked flag-salute study focuses on one judicial dispute and the disagreement over constitutional responsibility within it.
