I’m not sure if there is a factual answer to this but I don’t know where to post the question. Actually, there are two questions so without further ado, I will post them.
1.0 Has a retiring Supreme Court Justice ever recommended his/ her replacement?
2.0 If so, has the recommended replacement ever been appointed?
The article includes other instances of current and former justices making recommendations about appointments, but not necessarily for their own replacement.
