Subsidiarity Principle

The Subsidiarity Principle is a core governance principle of the European Union, defined in Article 5(3) of the Treaty on European Union. It states that in areas of non-exclusive competence, the Union shall act only if the objectives of the proposed action cannot be sufficiently achieved by the Member States, but can be better achieved at the Union level. In cyber resilience, this means data processing and security decisions should be made at the most effective and necessary level.

Taiwanese companies, especially in the semiconductor and high-tech supply chains, often handle sensitive data from EU clients and must comply with the GDPR. The principle influences data localization requirements and cross-border data transfers. Failing to establish controls at the appropriate level could be seen as improper processing, leading to fines of up to 4% of global annual turnover, jeopardizing international contracts and reputation.

The spirit of this principle aligns with several international standards. In the EU's GDPR, it is reflected in the principles of "data minimisation" and "purpose limitation." In ISO/IEC 27001:2022 (Information Security Management), clauses A.5.1 (Policies for information security) and A.5.3 (Segregation of duties), and in ISO/IEC 27701 (Privacy Information Management), clause 6.4.2.2 (Assigning access rights), all require defining responsibilities at appropriate levels to ensure effective decision-making and control.
