Summary Under the proposed Cloud and AI Development Act (CADA), proportionate enforcement is a statutory requirement that prevents a "one-size-fits-all" regulatory approach. As explicitly mandated in Article 26(3), measures taken by national competent authorities must be "effective, dissuasive and proportionate." This assessment must specifically regard the "nature, gravity, recurrence and duration of the infringement" and, crucially, the "economic, technical and operational capacity of the service provider concerned." This ensures that enforcement actions are calibrated to the specific risk posed and the provider's ability to comply, protecting smaller entities from existential threats while ensuring robust deterrence for major non-compliance.

Detail

The Cloud and AI Development Act (CADA) establishes a complex sovereignty framework for cloud computing services, relying on a decentralized enforcement model led by national competent authorities. To ensure this model functions fairly and effectively across the diverse European market, the proposal embeds the principle of proportionality directly into the core enforcement powers. This principle acts as a legal safeguard, ensuring that regulatory interventions are neither disproportionately burdensome for minor infractions nor insufficiently rigorous for systemic threats to Union assurance levels.

The Legal Mandate: Article 26(3)

The definitive definition of proportionate enforcement is located in Article 26(3) of the CADA proposal. This provision governs the exercise of both investigative and enforcement powers by the national competent authority of establishment. The text of the proposal is precise:

"Measures taken by national competent authorities of establishment in exercising their powers listed in paragraphs 1 and 2 shall be effective, dissuasive and proportionate, having regard, in particular, to the nature, gravity, recurrence and duration of the infringement or suspected infringement to which those measures relate, and, where relevant, the economic, technical and operational capacity of the service provider concerned."

This clause imposes a mandatory multi-factor analysis on authorities before any measure is finalized. It prohibits the automatic application of standard penalties or corrective orders. Instead, authorities must weigh the specific circumstances of the case against four distinct categories of factors:

  1. Nature of the infringement: This refers to the qualitative type of rule violated. For example, a procedural failure to submit a transparency notification under Article 23 is fundamentally different in nature from the intentional provision of misleading information during the recognition process for a Union assurance level under Article 17. The former is an administrative oversight; the latter strikes at the heart of the sovereignty framework's integrity.
  2. Gravity of the infringement: This assesses the severity of the consequences. A breach that compromises the Union assurance level of a service used by critical public infrastructure (e.g., law enforcement or defense) carries significantly more weight than a minor administrative delay in a non-critical context. The gravity determines the potential harm to public order and the Union's strategic autonomy.
  3. Recurrence and duration: This factor distinguishes between isolated errors and systemic failures. A first-time, short-lived breach may warrant a corrective order, whereas a pattern of non-compliance or a long-standing failure to meet assurance criteria suggests a governance breakdown, warranting stronger, more intrusive measures.
  4. Economic, technical, and operational capacity: This is the most dynamic element of the proportionality test. The proposal explicitly requires authorities to consider the provider's specific capabilities. A remedial measure or fine that might be negligible for a global hyperscaler could be existentially destructive for a small mid-cap enterprise (SMC). The authority must ensure that the measure is impactful enough to be "dissuasive" without being disproportionate to the provider's ability to survive and operate, unless the infringement is of such severity that no lesser measure would suffice.

The Interplay with Penalties (Article 24)

While Article 26 focuses on the powers and immediate measures of the authorities (such as ordering the cessation of infringements, imposing periodic penalty payments, or conducting inspections), it operates in tandem with Article 24, which sets out the general rules on penalties and compensation.

Article 24(1) requires Member States to lay down rules on penalties applicable to infringements that are "effective, proportionate and dissuasive." Furthermore, Article 24(2) elaborates on the specific criteria for imposing financial penalties, which mirror and expand upon the factors in Article 26(3). These additional criteria include:

  • The financial benefits gained or losses avoided by the infringing party due to the infringement.
  • Any previous infringements by the infringing party.
  • The infringing party's annual turnover in the Union.

This creates a cohesive enforcement ecosystem. Article 26 guides the immediate regulatory response (investigations, interim orders, cessation mandates), ensuring that the method of enforcement is tailored to the provider's capacity. Article 24 guides the ultimate financial sanction, ensuring the amount of the fine reflects the economic gain and the provider's turnover. Both articles require a proportionality assessment grounded in the provider's capacity and the severity of the breach, creating a consistent legal standard across the enforcement lifecycle.

The Central Role of the Competent Authority of Establishment

CADA adopts a "single point of contact" model to ensure consistent application of the proportionality principle. Article 25(4) grants exclusive competence to the Member State where the cloud computing service provider has its main establishment (defined as the head office or registered office where principal financial functions and operational control are exercised).

This centralization is critical for proportionate enforcement. The authority in the provider's home state is best positioned to evaluate the provider's overall economic, technical, and operational capacity. By concentrating this assessment in one jurisdiction, CADA ensures that enforcement actions are consistent across the Union and that the provider is not subjected to fragmented, potentially conflicting, or cumulatively disproportionate measures from multiple Member States simultaneously.

However, this exclusive competence does not insulate providers from cross-border scrutiny. Article 28 establishes a mechanism for cross-border cooperation. If a "competent authority of destination" (where the service is used) suspects non-compliance, it can request the authority of establishment to assess the matter. The authority of establishment must then act within two months. Crucially, any measures taken in response to such a request must still adhere strictly to the proportionality principles of Article 26(3), ensuring that the cross-border nature of the service does not dilute the requirement for a tailored, capacity-aware response.

What this means for you

For in-house counsel, compliance officers, and cloud service providers, understanding the mechanics of proportionate enforcement is a vital component of risk management and regulatory strategy.

1. Proactive Documentation of Capacity When facing an investigation or a suspected infringement, providers should be prepared to substantiate their "economic, technical and operational capacity." If a proposed measure appears disproportionate, you can construct a defense based on these specific factors. For instance, if a small provider is ordered to implement a complex, costly technical remediation that exceeds their current operational capabilities, you can argue that the measure is disproportionate. Instead, you can propose a scaled alternative that achieves compliance within your resource constraints, demonstrating a commitment to the "effective" outcome without the "disproportionate" burden.

2. Mitigation as a Proportionality Lever The factors of "recurrence" and "duration" are within your control. Proportionality favors entities that act swiftly to correct errors. If an infringement is identified, immediate corrective action can significantly reduce the "duration" of the breach and demonstrate that it is not a "recurrence" of a systemic issue. Documenting steps taken to mitigate harm, cooperate with authorities, and remedy the situation can directly influence the final enforcement decision, potentially leading to lighter penalties or less intrusive measures.

3. The "Effective and Dissuasive" Threshold It is a misconception that proportionality equates to leniency. The measures must simultaneously be "effective" and "dissuasive." For large providers with significant economic and technical capacity, a proportionate measure may still be severe. The goal is to ensure the penalty is felt enough to prevent recurrence, not merely to punish. Compliance programs must be robust enough to prevent repeat infractions, as recurrence is a key factor that authorities will use to escalate enforcement measures under Article 26(3).

4. Strategic Engagement with the Authority of Establishment Since the authority of establishment holds exclusive competence, building a cooperative and transparent relationship with this specific regulator is essential. They are the sole entity responsible for assessing your capacity and the nature of your infringements. Proactive communication can help frame the narrative around any issues, ensuring that the proportionality assessment is informed by your full context, including your technical roadmap and financial reality.

Common misconceptions

Misconception 1: Proportionality means automatic leniency for smaller companies. While economic capacity is a mandatory factor, proportionality does not grant immunity or automatic leniency. A small company that intentionally misrepresents its Union assurance level to win a public contract may still face severe, dissuasive measures, including heavy fines or the revocation of recognition. The measure must be proportionate to the infringement and the capacity, but it must still be "effective" and "dissuasive." If the infringement is severe, the measure must be severe, regardless of the provider's size.

Misconception 2: Each Member State can apply its own proportionality standards. No. CADA harmonizes the enforcement framework to prevent regulatory arbitrage. The authority of establishment has exclusive competence (Article 25(4)), and the criteria for proportionality are defined uniformly at the Union level in Article 26(3). This ensures that a provider is not subjected to conflicting or cumulative disproportionate measures across the EU and that the same infringement is treated consistently regardless of where the service is consumed.

Misconception 3: Proportionality only applies to financial fines. Proportionality applies to all measures taken by the authority. This includes investigative powers (such as the scope and intrusiveness of inspections under Article 26(1)) and enforcement orders (such as the cessation of infringements or periodic penalty payments under Article 26(2)). An intrusive, costly, or operationally disruptive inspection may be deemed disproportionate for a minor administrative error, just as a light fine may be disproportionate for a severe security breach that threatens public order.
