Charles' friend is very likely right but for the wrong reason. While at one time, the FIDE laws recognized pepetual check as a draw condition in its own right, that is no longer true. Perpetual check is not now defined in the laws. The reason for this is that all perpetual check situations lead to triple repetition (or in theory, overstepping the fifty move rule--in practice all perpetual checks become triple repetitions). Since the laws permit the player on move the free choice of legal moves, it is permissible to intentionally make moves leading to triple repetition and the resulting draw. See the official laws for the technicalities of the triple repetition rule.
