Introduction

The case of Lanning & Anor v. R ([2021] EWCA Crim 450) presents critical insights into the admissibility of bad character evidence under Section 101 of the Criminal Justice Act 2003 and the interpretation of the Overwhelming Supervening Act (OSA) in joint enterprise scenarios. The appellants, Alex Lanning (AL) and Jonathan Camille (JC), faced convictions for murder and manslaughter respectively, with their appeals focusing on procedural and evidential grounds.

Summary of the Judgment

On March 30, 2021, the England and Wales Court of Appeal (Criminal Division) delivered its judgment in Lanning & Anor v. R. AL was convicted of the murder of Tashan Daniel (TD) through a fatal stabbing, while JC was convicted of TD's manslaughter. AL and JC appealed their convictions, challenging the admissibility of AL's prior bad character evidence and disputing the application of OSA in JC's case.

The Court of Appeal upheld both convictions. Regarding AL, the court affirmed the admission of his previous convictions for unlawful wounding and drug offenses as relevant under Section 101(1)(d) and (g) of the Criminal Justice Act 2003. For JC, the appeal concerning the OSA was dismissed, with the court determining that the use of a knife by AL did not constitute an overwhelming supervening act that would negate JC's criminal responsibility.

Analysis

Precedents Cited

The judgment extensively references key statutes and precedents to substantiate its reasoning:

• Criminal Justice Act 2003, Section 101: Governs the admissibility of bad character evidence, outlining specific conditions under which such evidence can be introduced.
• R v Jogee [2016] UKSC 8: Redefined the principles of joint enterprise, emphasizing the intent behind secondary participants in an offense.
• R v Hay [2017] EWCA Crim 1851: Clarified matters in issue as they pertain to the defendant's intentions and associations.
• R v Tas [2018] EWCA Crim 2603 and R v Harper [2019] EWCA Crim 343: Further elaborated on the concept of Overwhelming Supervening Act in homicide cases.

Notably, the court distinguished cases like R v Bullen and R v Fyle, which dealt with propensity evidence, as being unrelated to the present appeal focused on Section 101(1)(d).

Legal Reasoning

The court's analysis centered on two main legal issues: the admissibility of AL's prior bad character evidence and the applicability of OSA in JC's case.

• Admissibility of Bad Character Evidence: The prosecution sought to introduce AL's prior convictions to challenge his credibility and suggest a propensity for violence. AL contended this evidence was inadmissible and prejudicial. However, the court held that the evidence was pertinent to an important matter in issue—whether AL deliberately stabbed TD with intent. The judge’s instructions to the jury to regard this evidence with caution further mitigated any potential unfair prejudice.
• Overwhelming Supervening Act (OSA) in Joint Enterprise: JC appealed on the grounds that AL's use of a knife constituted an OSA, which should absolve JC of criminal responsibility. The court, referencing post-Jogee jurisprudence, concluded that the use of the knife did not meet the stringent criteria for an OSA. The violent escalation was deemed a foreseeable risk inherent in the joint enterprise, thereby maintaining JC's culpability.

Impact

This judgment reinforces the permissibility of admitting relevant bad character evidence under Section 101 when it directly pertains to significant issues in the case. It underscores the judiciary's confidence in juries to weigh such evidence appropriately when accompanied by clear judicial directions. Additionally, the dismissal of the OSA argument in joint enterprise cases following the Jogee decision delineates the boundaries of secondary liability, ensuring that escalations like the use of a weapon remain within the scope of the original enterprise.

Complex Concepts Simplified

Bad Character Evidence (Section 101, CJA 2003)

Bad character evidence refers to past misconduct or criminal behavior of a defendant that the prosecution introduces to suggest a propensity to commit the current offense. Under Section 101, such evidence is admissible if it is pertinent to a crucial issue in the case, such as intent or credibility, and if its probative value outweighs any prejudicial impact.

Overwhelming Supervening Act (OSA)

An OSA is an unforeseeable event that occurs after the defendant's initial wrongful act, which is so significant that it breaks the chain of causation, absolving the defendant of criminal responsibility for the resultant harm. In joint enterprise, if a secondary participant's actions are superseded by such an act, they may be exonerated. However, the threshold for OSA is exceedingly high, requiring that no reasonable person could have anticipated the event.

Joint Enterprise

Joint enterprise involves two or more individuals who agree to undertake a criminal venture. Participants can be held liable for the actions of others if those actions are within the scope of the agreement and if they share the intent behind the venture.

Conclusion

The Court of Appeal's decision in Lanning & Anor v. R serves as a significant reaffirmation of the admissibility of bad character evidence when directly relevant to pivotal case issues. It also clarifies the limited applicability of OSA within the framework of joint enterprise, especially post-Jogee. This judgment emphasizes the judiciary's role in ensuring that evidence presented in trials is both pertinent and balanced, safeguarding the fairness of proceedings while upholding the integrity of the criminal justice system.
