I recall reading a science fiction story in Analog (I think in the 1980s) about judges being profiled as a way to win court cases. Items such as arguments used based on their history, delivery of arguments and review of previous cases and their judgements. The one particular case highlighted that the one judge preferred short, direct arguments, and this was used to help win the case. If I recall, the lawyers etc had earpieces (or maybe briefcases) with a wireless link to a van outside the court which had a data connection back to the office where the computer gave real time updates. I am not sure what the story was called .....

The Paradise Game by Brian Stableford - A Hooded Swan novel - book 4.

And it also only needs 3 legs ....
