We develop a statistical framework to evaluate evidence of alleged cheating with illegal signalling in sports from a forensic perspective. We explain why instead of a frequenstic procedure, a Bayesian approach is called for. We apply this framework to cases of alleged cheating in professional bridge and professional baseball. The diversity of these applications illustrates the generality of the method.
