The Logic of Equality: A Formal Analysis of Non-discrimination Law

This work proposes a formal-logical method for examining the indeterminacy of legal discourse, using the example of the non-discrimination norm. It shows that the indeterminacy of a legal concept does not mean that it is completely chaotic - the indeterminacy of the non-discrimination norm arises out of, and presupposes, a determinate formal structure, which remains fixed and constant both within and across jurisdictions, regardless of institutional or doctrinal differences. To illustrate the argument, cases are presented from a variety of jurisdictions including the United States Supreme Court, the European Court of Human Rights, the European Court of Justice, and the German Constitutional Court.
