It struck me as quite sad and pathetic that Rutherford was so desperate to be a 'real' judge, that he gave himself the title and set up a structure in which he could act out his fantasty to lots of uneducated people by writing impressive books in which he got to pretend he was a real judge.
He could talk about legalistic stuff and expound his knowledge of legal procedure, and millions of window cleaners and shop assistants whould go 'Ohhhh Ahhhh JUDGE Rutherford blah blah blah'. What an ego trip.
