Cui bono, asked the advocate: who benefits? Despite Lord Woolf's well-known aversion to the use of dead languages in the courtroom - although the Lord Chief Justice did not flinch when Sir Sydney Kentridge, QC, threw a couple of Latin tags at him in the hunting case yesterday - counsel's repeated cries of cui bono raised no objection from the judges or jury. But this should come as no surprise: the lawyer was Cicero and the trial took place in 81 BC. Latin was, of course, their common tongue.
