LEGAL PRINCIPLE: CRIMINAL PROCEDURE – Defence of Alibi – Duty to Raise Alibi at Earliest Opportunity
PRINCIPLE STATEMENT
A plea of alibi should be raised at the earliest opportunity; where it is not raised until the appellant gives testimony in the witness box, the police have no opportunity to investigate the alibi.
RATIO DECIDENDI (SOURCE)
"Now, a plea of alibi which should have been raised at the earliest opportunity was not raised until the appellant went into the witness box to give his testimony. In the circumstance the Police had no opportunity to investigate the alibi, if the defense is to be so regarded."
EXPLANATION / SCOPE
Alibi claims (“I was elsewhere when the crime occurred”) should be disclosed at the earliest opportunity—ideally during police investigation or at arraignment. Early disclosure allows police to investigate, verify claims, and interview alibi witnesses. Late disclosure (first raised during defense testimony) denies prosecution opportunity to investigate, appearing tactical rather than genuine. Courts view late alibis skeptically as potentially fabricated defenses. While late alibi doesn’t automatically fail, courts consider the timing when assessing credibility. The principle balances the accused’s right to defense against fair trial requirements and prosecution’s ability to investigate claims. Early disclosure promotes truth-finding and prevents surprise defenses that cannot be properly tested.
