This paper provides first the condition under which the majority of an odd number of jurists is more likely to choose the better of two alternatives than a single jurist selected at random from the jurists, given that each jurist has a probability larger than one half of choosing correctly, and second that the same inequality holds for a subset of an odd number of jurists chosen at random from the original group.
