 Since the alibi involves evidence of innocence rather than guilt, the privilege against self-incrimination is not implicated.In Canada, the defence must disclose an alibi defence with sufficient time for the authorities to investigate the alibi, and with sufficient particularization to allow for a meaningful investigation.Failure to comply with the two requirements will result in the court making an adverse inference against the alibi defence (but will not result in the exclusion of the alibi defence).
