Micronations challenge existing conceptions of statehood and international legal personality. They do so by engaging in the rituals of statehood rather than contesting them. In practice, this means that although usually unqualified or unskilled in law, proponents act through their understanding of the law rather than acting outside the law. In this chapter we explore in more detail how micronations assert and perform sovereignty. We examine the legal instruments that micronationalists identify when seeking to find a lawful basis to justify secession and proclaim their independence, and outline their strained legal arguments.
