The 1965 Oklahoma Supreme Court scandal was a political scandal in the U.S. state of Oklahoma involving judicial misconduct on the Oklahoma Supreme Court. Justice N. S. Corn was convicted in 1964 on federal tax evasion charges. After his conviction, he implicated himself, Samuel Earl Welch, and Napoleon Bonaparte Johnson in accepting bribes to decide cases.
Corn had resigned after his conviction and Justice Welch resigned after impeachment precedings began in the Oklahoma House of Representatives. Justice Johnson refused to resign and became the first Oklahoma Supreme Court Justice impeached and removed from office.
