The rule was unusual in that it seemed to require the lawyer who had filed the complaint to take the witness stand and undergo cross-examination by his accuser. Such an occurrence was, like a Rule 11 hearing itself, exceedingly rare. A lawyer’s job is to argue his client’s cause, not to act as a witness whose very testimony could, perhaps, result in his client’s case being stricken.
