More specifically, solicitors are lawyers who deal directly with the client, while barristers argue cases in court.
Do they still wear those silly wigs?
Many judges in Australia do, though it's fast becoming an optional thing. It's rather annoying, because unless you know the judge, you have to bring along a wig just in case.
Oh, and some solicitors do act as pseudo-barristers through solicitor advocate programs, which both the prosecution and the main defence practice have introduced recently.
