NON-FORCIBLE MEASURES AND THE LAW OF SELF-DEFENCE

The right of self-defence is usually presented as an exception to the principle of non-use of force. Conventional wisdom therefore holds that the right of self-defence can only be relied on to justify those measures constituting a threat or use of force. This article rejects that claim. It argues that self-defence is a general right under international law and, as such, can be invoked to justify all measures necessary to repel an armed attack regardless of whether they are forcible or non-forcible in nature. To support this argument, this article examines the genesis of the right of self-defence under customary international law, the text of Article 51 of the United Nations Charter, the structure of the United Nations Charter and State practice on Article 51.
