In 1954, Congress revised requirements for senior status. Federal judges or justices could still assume senior status at seventy with ten years of service, but they could also assume senior status at 65 with fifteen years of service. In 1984, the requirements were further revised to what is often called the "Rule of 80": once a judge or justice reached age 65, any combination of years of age and years of service on the federal bench which totaled to eighty entitled the judge to assume senior status.
