Code in the DaVinci Code decision
From The BBC:
The judge who presided over the failed Da Vinci Code plagiarism case at London's High Court hid his own secret code in his written judgement. Seemingly random italicised letters were included in the 71-page judgement given by Mr Justice Peter Smith, which apparently spell out a message. Mr Justice Smith said he would confirm the code if someone broke it. "I can't discuss the judgement, but I don't see why a judgement should not be a matter of fun," he said.
