This chapter looks at derogations from the European Convention on Human Rights for military operations. It discusses some of the benefits that derogation would have for both the European Court of Human Rights and contracting States to the Convention. It argues that derogations can create flexibility within the legal paradigm governing military operations without exceeding several defined limits. It would compel the European Court of Human Rights to engage with international humanitarian law and provide a sound legal basis for many State activities during military operations. The chapter also considers how the language of Article 15 could function to limit recourse to derogations for certain military operations, particularly extra-territorial military operations. The chapter looks at how Article 15 should be interpreted and applied by the Court to derogations for military operations.
