Introduction

The case of CS & Anor, R v ([2021] EWCA Crim 134) before the England and Wales Court of Appeal (Criminal Division) is a pivotal judgment that clarifies the temporal scope of Section 45 of the Modern Slavery Act 2015. The applicants, CS and Mr. Le, both victims of trafficking, sought to rely on the statutory defense provided under Section 45 for offenses committed prior to the Act's commencement on 31 July 2015. This commentary delves into the Court's comprehensive analysis, elucidating the legal principles established and their implications for future cases involving victims of trafficking.

Summary of the Judgment

The Court of Appeal unanimously refused the applications for permission to appeal by both applicants, CS and Mr. Le. Central to the decision was the determination that Section 45 of the Modern Slavery Act 2015 does not possess retrospective effect. Consequently, it does not extend to offenses committed before its enactment on 31 July 2015. The court further addressed procedural matters concerning the jurisdiction of appeals from Magistrates' Courts and the appropriateness of granting anonymity to the applicants.

Analysis

Precedents Cited

The judgment extensively referenced prior Court of Appeal decisions to contextualize and support its reasoning:

• R v LM [2010] - Discussed protection from prosecution for trafficking victims.
• R v N, Le [2012] - Explored earlier applications of defenses for trafficking victims.
• Other significant cases include R v L [2013], R v VSJ [2017], R v EK [2018], R v O and N [2019], R v O [2019], and R v DS [2020].

These precedents collectively underscored the evolution of legal protections for trafficking victims and were instrumental in shaping the Court's interpretation of Section 45's applicability.

Legal Reasoning

The crux of the Court’s reasoning hinged on the principle of statutory presumption against retrospective effect. The court meticulously examined whether Parliament intended Section 45 to apply to pre-enactment offenses. Despite arguments to the contrary, including the lack of explicit temporal limitations and the inclusion of retrospective definitions in Section 56, the Court concluded that there was no clear indication of intended retrospectivity for Section 45. Key points include:

• The presumption against retrospective legislation serves fairness and legal certainty.
• Regulatory provisions explicitly stating non-retrospection pertain only to specified amendments, not to Section 45.
• Comparative analysis with other statutory defenses (e.g., partial defenses in murder) reinforced the presumption.
• Precedent cases consistently upheld non-retrospective application unless explicit language indicates otherwise.

Moreover, the Court assessed the defendants' claims regarding abuse of process and the adequacy of mitigation in sentencing, ultimately finding that the convictions and sentences were not unsafe or manifestly excessive.

Impact

This judgment solidifies the understanding that Section 45 of the Modern Slavery Act 2015 is applicable solely to offenses committed post-commencement. It underscores the importance of temporal boundaries in statutory defenses and reinforces the judiciary's adherence to principles of non-retrospectivity. Consequently, defendants seeking to leverage Section 45 must ensure that their offenses fall within the Act's effective period. This decision also delineates the appropriate avenues for appeals and underscores the limited scope for retroactive legal defenses, thereby guiding future litigants and legal practitioners in similar contexts.

By firmly establishing that the defense is not available for offenses committed prior to the Act's enactment, the ruling provides clarity and consistency in the legal landscape surrounding trafficking and its repercussions. This judgment emphasizes the judiciary's role in upholding legislative intent, ensuring that statutory defenses are applied within their intended temporal boundaries, and maintaining the integrity of legal processes.

For legal practitioners and victims of trafficking, this judgment delineates the extent and limitations of available defenses, guiding future litigation and advocacy efforts.
