Introduction
This essay examines the legal challenges brought by Member State A (MS A) against Directive 2024/2831, known as the Platform Work Directive (PWD), which was adopted on 24 October 2024 by the European Parliament and Council to improve working conditions in platform work. As trainee lawyers shadowing an Advocate General at the Court of Justice of the European Union (CJEU), we have been tasked with drafting a recommendation on two key legal issues raised by MS A: (1) whether Article 153(2)(b) of the Treaty on the Functioning of the European Union (TFEU) can serve as a valid legal base for the PWD, given claims of unreasonable administrative burdens and negative impacts on small and medium-sized enterprises (SMEs), and (2) whether the PWD violates the principle of subsidiarity under Article 5 of the Treaty on European Union (TEU) due to differences in national labour markets. This analysis will present arguments both supporting and opposing MS A’s positions on each issue, culminating in a joint opinion on the most defensible stance for each point. The essay draws on relevant EU law principles, treaties, and case law to provide a balanced and critical evaluation, ensuring a sound understanding of the legal framework while acknowledging the complexity of harmonising labour conditions across diverse Member States.
Issue 1: Legal Basis Under Article 153(2)(b) TFEU
Arguments in Favour of MS A: Art. 153(2)(b) as an Invalid Legal Base
MS A contends that Article 153(2)(b) TFEU cannot serve as the legal base for the PWD because the Directive imposes unreasonable administrative burdens and disproportionately harms SMEs, thus violating the explicit limits of this provision. Article 153(2)(b) allows the EU to adopt directives setting minimum requirements for working conditions, provided they do not impose excessive administrative, financial, or legal constraints, particularly on SMEs, as stipulated in the second subparagraph. MS A argues that the PWD’s reporting and information obligations create significant compliance costs for platform-based businesses, many of which are SMEs. For instance, requirements to monitor and report on workers’ conditions may necessitate new systems and personnel, which could be financially unsustainable for smaller firms with limited resources. This perspective finds potential support in the CJEU’s reasoning in cases such as Commission v United Kingdom (Case 383/92), where the Court ruled that EU measures under social policy must respect the proportionality of burdens imposed on economic operators (Durston, 1992).
Furthermore, MS A asserts that the negative impact on SMEs undermines the broader objectives of Article 151 TFEU, which seeks to promote employment and improve living and working conditions while ensuring proper social protection. By stifling SME growth and innovation in the digital economy, the PWD may hinder job creation, arguably contradicting the goal of employment promotion. Therefore, MS A’s position is that the Directive exceeds the permissible scope of Article 153(2)(b) by disregarding its protective caveats for smaller businesses, rendering this provision an invalid legal base.
Arguments Against MS A: Art. 153(2)(b) as a Valid Legal Base
Conversely, the European Commission and proponents of the PWD maintain that Article 153(2)(b) TFEU is an appropriate legal base. This provision explicitly empowers the EU to adopt directives on working conditions, a category that logically encompasses platform work given its growing prevalence and associated challenges, such as precarious employment status and lack of social protections. The PWD’s aim to establish minimum standards—such as ensuring fair classification of platform workers and transparency in algorithmic management—aligns directly with the objectives of improving working conditions under Article 151 TFEU. Indeed, the EU has previously acted under Article 153 to address emerging labour issues, as seen in directives on part-time work and temporary agency work, demonstrating the provision’s applicability to diverse work arrangements (Barnard, 2012).
Regarding the alleged burdens on SMEs, the Directive’s text likely includes derogations or phased implementation periods to mitigate disproportionate impacts, reflecting the requirement under Article 153(2)(b) to consider SME constraints. Moreover, the CJEU has consistently held that social policy measures must balance economic considerations with social protection goals, as evident in United Kingdom v Council (Case C-84/94), where the Court upheld the Working Time Directive despite economic objections (Craig and de Búrca, 2020). Thus, while burdens may exist, they do not necessarily render the legal base invalid if they are proportionate to the social objectives served. The PWD arguably advances the core aims of Article 151 by protecting vulnerable workers, thereby justifying its basis under Article 153(2)(b).
Joint Opinion on Legal Basis
After weighing both sides, our group concludes that Article 153(2)(b) TFEU constitutes a valid legal base for the PWD. The Directive falls within the scope of working conditions as defined by the Treaty, and its objectives align with the social policy goals of Article 151. While MS A’s concerns about administrative burdens on SMEs are valid and merit consideration, the CJEU’s jurisprudence suggests that such burdens must be demonstrably disproportionate to invalidate a legal base. Without specific evidence that the PWD’s requirements are excessive beyond reasonable mitigation (e.g., through exemptions), the balance tips in favour of the Commission. However, we recommend that the Court scrutinise the proportionality of the Directive’s measures to ensure compliance with the SME safeguard in Article 153(2)(b).
Issue 2: Subsidiarity Concerns Under Article 5 TEU
Arguments in Favour of MS A: Violation of Subsidiarity
MS A also challenges the PWD on the grounds that it violates the principle of subsidiarity under Article 5(3) TEU, which mandates that the EU act only if objectives cannot be sufficiently achieved by Member States and can be better achieved at the Union level. MS A argues that the diverse labour market conditions across Member States—ranging from wage structures to platform penetration—mean that a uniform EU directive cannot effectively address these nuances. National consultations in MS A reportedly indicated that the PWD would disrupt local labour markets and hinder SME operations, suggesting that Member States are better positioned to tailor solutions to their unique contexts. This aligns with the subsidiarity principle’s emphasis on decentralised decision-making where national action is feasible (Schütze, 2015).
Additionally, MS A contends that existing national laws on platform work, though varied, are sufficient to address local issues, and EU intervention risks overriding these tailored approaches. The CJEU has previously annulled EU measures for breaching subsidiarity, as seen in Germany v Parliament and Council (Case C-233/94), underscoring the importance of justifying Union-level action over national competence (Craig and de Búrca, 2020). Thus, MS A’s position is that the PWD fails the subsidiarity test by imposing a one-size-fits-all solution where national measures could suffice.
Arguments Against MS A: Compliance with Subsidiarity
On the other hand, the Commission likely argues that the PWD complies with subsidiarity because platform work presents a cross-border challenge that cannot be adequately addressed by individual Member States. Platform companies like Uber operate across multiple jurisdictions, creating disparities in worker protections that can lead to a ‘race to the bottom’ in standards if left to national regulation alone. EU-level action ensures a harmonised baseline, preventing regulatory arbitrage and protecting workers in a transnational digital economy. The Commission’s impact assessments prior to the PWD’s adoption presumably demonstrated this necessity, fulfilling the burden of justification under Article 5(3) TEU (Barnard, 2012).
Moreover, the CJEU has often upheld EU measures where transboundary issues are evident, as in Parliament v Council (Case C-377/98), affirming that social policy harmonisation can be justified when national action risks inconsistency (Schütze, 2015). The PWD’s objective of establishing minimum standards, rather than fully uniform rules, also leaves room for Member States to adapt implementation to local conditions, arguably mitigating subsidiarity concerns. Therefore, the Commission’s position is that Union action is both necessary and better suited to achieve the Directive’s goals.
Joint Opinion on Subsidiarity
Our group finds that the PWD likely complies with the principle of subsidiarity under Article 5(3) TEU. The transnational nature of platform work and the risk of divergent national standards undermining worker protections provide a compelling case for EU-level intervention. While MS A’s concerns about national labour market differences are understandable, the Directive’s focus on minimum standards offers flexibility for local adaptation, reducing the risk of overreach. We recommend that the Court examine the Commission’s evidence for why EU action is preferable, but based on current understanding, the PWD appears to meet the subsidiarity threshold.
Conclusion
In conclusion, this recommendation has critically assessed MS A’s challenges to the Platform Work Directive on the grounds of legal basis and subsidiarity. On the issue of legal basis, we find that Article 153(2)(b) TFEU is a valid foundation for the PWD, as its objectives align with social policy goals under Article 151, and potential burdens on SMEs must be proven disproportionate to invalidate this base. Regarding subsidiarity, we conclude that the transnational challenges of platform work justify EU action, outweighing concerns over national differences, provided the Commission’s rationale is substantiated. These findings underscore the delicate balance between harmonisation and national autonomy in EU social policy, with implications for future directives in emerging sectors. The CJEU must ensure proportionality and justification are rigorously evidenced, maintaining trust in EU competence while safeguarding Member State interests.
