DPP v Mary Kelly

Factual and Procedural Background

The Applicant forcibly entered an area of Shannon Airport on 29 January 2003 and caused significant damage to a United States Naval aircraft that was refuelling en route to Sicily in connection with military operations. The Applicant admitted to damaging the aircraft with the stated purpose of preventing it from going to Iraq to protect innocent Iraqi people.

The Applicant was charged with two offences: trespass and causing criminal damage without lawful excuse under s.2(1) of the Criminal Damage Act 1991. At the first trial, the Applicant was convicted of trespass and received a suspended sentence; the jury failed to reach a verdict on the criminal damage charge, resulting in a retrial. At the second trial, the Applicant was convicted of criminal damage and sentenced to two years imprisonment, suspended for four years. The Applicant represented herself at the second trial and later applied for leave to appeal the conviction.

Legal Issues Presented

1. Whether the Applicant was entitled to rely on the statutory defence of "lawful excuse" under the Criminal Damage Act 1991 as amended by the Non-Fatal Offences against the Person Act 1997.
2. Whether the learned trial judge misdirected the jury regarding the defence of lawful excuse, particularly concerning the requirement of immediacy in the threat to be averted.
3. Whether the trial was conducted in breach of constitutional rights due to the Applicant representing herself without counsel and the adequacy of the trial process.

Arguments of the Parties

Applicant's Arguments

• The Applicant asserted that she had an honest belief that damaging the aircraft was reasonable to prevent harm to innocent Iraqi people and thus had a lawful excuse under s.6(2) of the Criminal Damage Act 1991 as amended.
• She contended that the learned trial judge wrongly excluded expert evidence intended to demonstrate the reasonableness of her actions and misdirected the jury by imposing a requirement of an immediate threat in time and space, which is not present in the amended statute.
• The Applicant argued that the defence of lawful excuse does not require the threat to be immediate or spatially connected, and that the judge's direction effectively denied her defence and directed the jury to convict.
• She emphasized that the prosecution bears the burden of disproving the defence of lawful excuse beyond reasonable doubt.

Prosecutor's Arguments

• The prosecution maintained that despite the amendment removing the express requirement of "immediate need of protection," an implied requirement for immediacy in time and space remains.
• They argued that the defence of lawful excuse cannot apply to actions taken to protect persons or property thousands of miles away and at some future time.
• The prosecution contended that the Applicant's evidence and expert testimony regarding international law and the impact of her actions were irrelevant to the statutory defence.

Court's Reasoning and Analysis

The Court analysed the statutory provisions of the Criminal Damage Act 1991 and its 1997 amendment, focusing on the defence of lawful excuse. The original s.6(2)(c) required an "immediate need of protection," an objective condition, as a prerequisite for the defence. The 1997 amendment substituted this with a subjective test, assessing the reasonableness of the act in the circumstances as the defendant believed them to be, removing the express requirement of immediacy.

The Court found that the learned trial judge appeared to have misunderstood or been unaware of this amendment during much of the trial, repeatedly emphasizing a requirement for an immediate threat in time and space, contrary to the amended statute's text. The prosecution maintained that an implied immediacy requirement persisted, but the Court noted this was a problematic construction, potentially rendering the amendment meaningless and conflicting with principles of statutory interpretation.

The trial judge's directions to the jury, asserting the absence of a "connection in time and space" between the damage caused and the threat intended to be averted, effectively precluded the defence of lawful excuse. The Court observed that the judge did not clarify whether this was a question of law or fact, nor did he properly instruct the jury on the burden of proof or the subjective nature of the defence.

The Court also highlighted the constitutional importance of clarity in criminal law and the right of the defendant to a fair trial, noting that the Applicant, as a lay litigant, was not adequately informed or assisted regarding the complex legal issues arising from the statutory amendment and its interpretation.

Holding and Implications

The Court granted the Applicant's appeal, quashed the conviction, and treated the application for leave to appeal as the hearing of the appeal.

Holding: The conviction was not safe or satisfactory due to misdirection on the defence of lawful excuse and the trial judge’s failure to properly apply the amended statutory provisions.

Implications: The decision directly affects the parties by overturning the Applicant's conviction. The Court did not establish new precedent beyond the resolution of this appeal but noted the statutory provisions involved are ambiguous and confusing. The Court suggested that the relevant legislation might benefit from reconsideration and clearer drafting to ensure that laypersons and courts can readily understand the law, particularly in cases involving complex defences such as lawful excuse.
