Similar occurrences evidence can show an act was intentional when repeated, tending to negate accident and indicate knowledge. When the question is whether an act was accidental or intentional, the fact that the act formed part of a series of similar occurrences in each of which the same person was concerned is relevant, because repeated similar events involving the accused tend to show that a given instance was not accidental; illustrations include repeated insured house fires with insurance payments, consistently false accounting entries favouring the recipient, and multiple deliveries of counterfeit currency.
