As reported in today's Australian Financial Review, the NSW Court of Appeal has told the Administrative Decisions Tribunal's Legal Services Division that it got it wrong when it found a Sydney solicitor guilty of gross overcharging. The case is  LN v Legal Services Commissioner  [2007] NSWCA 130  Though the solicitor signed the bill, he did not really read it, and the Legal Services Commissioner obviously didn't think hard enough about the charge, since the solicitor got off on the basis that he did not have personal culpability for gross overcharging. It is not well understood that there is no concept of vicarious liability for professional misconduct or unsatisfactory professional conduct. He might have been disciplined for failure to supervise, I suppose, but that was not what he was charged with. The relevant decisions below are here and here.
