Business Continuity Plan Testing: Legal Framework, Regulatory Requirements and Case Laws

1. Introduction

Business Continuity Plan (BCP) testing is a systematic process through which financial institutions assess their ability to maintain or restore critical operations during disruptions. These disruptions may include cyberattacks, power failures, natural disasters, telecommunications outages, system breakdowns and third-party service failures.

In banking, business continuity testing protects depositors, payment systems, financial stability and customer information. It also helps institutions demonstrate compliance with operational resilience, risk management and supervisory requirements.

Within Spain and the European Union, BCP testing is closely associated with the Digital Operational Resilience Act (DORA), banking governance requirements and cybersecurity regulation.

2. European Union Legal Framework

Digital Operational Resilience Act (DORA)

Regulation (EU) 2022/2554, applicable since 17 January 2025, establishes operational resilience requirements for financial entities.

Article 11 addresses ICT response and recovery, including business continuity policies and disaster recovery arrangements.

Article 11(6) requires periodic testing of relevant ICT business continuity and response and recovery plans, including testing at least annually and following substantive changes to ICT systems supporting critical or important functions.

Article 24 establishes broader digital operational resilience testing requirements.

Capital Requirements Directive

Directive 2013/36/EU, as amended, establishes governance and risk management obligations for credit institutions.

European Banking Authority Guidelines

EBA guidelines on ICT and security risk management provide additional supervisory context, subject to their interaction with DORA and the applicable regulatory framework.

3. Spanish Regulatory Framework

Spanish banks operate under national banking legislation and directly applicable European regulations.

Relevant instruments include:

Law 10/2014 on the organisation, supervision and solvency of credit institutions.

Royal Decree 84/2015 implementing aspects of Spanish banking supervision.

DORA and applicable regulatory technical standards.

European Central Bank supervisory requirements for significant credit institutions.

The Bank of Spain and, where applicable, the ECB oversee operational risk management and compliance.

Institutions must ensure that continuity arrangements address important banking services, ICT dependencies and outsourced operations.

4. Essential Components of BCP Testing

Risk Assessment: Identify operational threats and vulnerabilities affecting critical services.

Business Impact Analysis: Determine essential functions, acceptable disruption periods and recovery priorities.

Recovery Testing: Verify backup systems, alternative processing arrangements and data restoration capabilities.

Cyberattack Simulation: Assess responses to ransomware, compromised credentials and unavailable infrastructure.

Third-Party Testing: Evaluate dependencies on cloud providers, payment processors and telecommunications operators.

Documentation: Record test objectives, results, identified deficiencies, corrective actions and management approvals.

Testing methods include tabletop exercises, technical recovery simulations and controlled failover testing.

5. Relevant Case Laws

Case Law 1: Tietosuojavaltuutettu v Jehovan todistajat, Case C-25/17, CJEU, 10 July 2018

Facts: A religious community's members collected personal information during organised activities, raising questions about responsibility for processing.

Legal Issue: Whether an organisation could qualify as a joint controller without directly accessing all collected information.

Judgment: The CJEU recognised that joint controllership could arise from participation in determining processing purposes and means.

Legal Principle/Ratio: Responsibility for personal data processing depends on actual involvement in determining its purposes and means.

Significance: The decision provides an analogous principle for allocating data protection responsibilities during outsourced continuity operations. It is not specifically a BCP testing judgment.

Case Law 2: Wirtschaftsakademie Schleswig-Holstein, Case C-210/16, CJEU, 5 June 2018

Facts: A company administered a Facebook fan page involving the processing of visitor information.

Legal Issue: Whether the administrator shared responsibility for personal data processing.

Judgment: The CJEU recognised joint controllership in the circumstances.

Legal Principle/Ratio: Multiple organisations may share data protection responsibilities according to their respective involvement.

Significance: Financial institutions should clarify data processing responsibilities when third-party providers participate in continuity testing.

Case Law 3: Lloyd v Google LLC [2021] UKSC 50

Facts: Proceedings concerned alleged unlawful collection and use of personal information.

Legal Issue: Whether compensation could be awarded uniformly without proving individual material damage or distress under the applicable legislation.

Judgment: The UK Supreme Court rejected the representative damages claim as formulated.

Legal Principle/Ratio: Compensation depends on the applicable statutory requirements and proof of compensable harm.

Significance: Although outside Spain and concerning earlier UK data protection legislation, the case illustrates why evidence of harm matters in data-related claims following operational failures.

6. Liability and Compliance Risks

Failure to maintain and test effective continuity arrangements may expose financial institutions to supervisory measures, contractual disputes and potential civil liability.

However, a failed test does not automatically establish legal liability. The applicable regulatory duty, breach, causation and resulting harm must be assessed.

Banks should maintain test records, remediation registers, escalation procedures and board-level oversight.

7. Conclusion

Business Continuity Plan testing is an essential component of banking operational resilience in Spain and the European Union.

The central legal principle is that financial institutions must establish, test, document and continuously improve proportionate continuity arrangements capable of supporting critical operations during disruption.

Effective testing strengthens regulatory compliance, customer protection and institutional resilience.
