I don’t like the concept of “retired judges”. Weren’t some of them voted OUT of office (defeated)?
28 U.S. Code § 371 - Retirement on salary; retirement in senior status
(a) Any justice or judge of the United States appointed to hold office during good behavior may retire from the office after attaining the age and meeting the service requirements, whether continuous or otherwise, of subsection (c) and shall, during the remainder of his lifetime, receive an annuity equal to the salary he was receiving at the time he retired.
It sounds like "Judge" is a pretty "cushy job"
