The preceding chapters demonstrate that domestic law has been used by international courts and tribunals in a variety of different ways to interpret international legal rules or instruments. Each instance of comparative reasoning is inextricably linked to the legal and historical context in which it occurs and in which the court or tribunal operates. The novelty of the specific legal regime, the presumed knowledge of other states parties or the presence of nebulous treaty standards are all factors that have led to the use of domestic law as a means of interpretation. As such, drawing general conclusions from a study such as this is difficult.
