Everything to do with the magistracy per se is as political correct as far as that terminology can be found anywhere in my limited experience. Nothing exposes this outlook on the world more than the use or non use of the word “chairman”. This is not the time nor place to delve into the etymology of the word but for those who are curious this site might be of interest.
My own curiosity in the wordform was awakened a few weeks ago with an invitation to attend later this week a training session for “chairtakers”. This was my first awareness of this form of address for those approved to sit in the middle chair. Perhaps I lead too quiet a life and should get out more.
