It is widely accepted that sovereign States are entitled to control the admission and expulsion of non-nationals into their territory, subject to various treaties and other customary international laws. In a globalised world, however, countries cannot simply close their borders: people are mobile. What governments must therefore do is devise judicial and/or administrative processes for determining access and deciding what to do with those whom they wish to deport or remove.1 These processes must be fair and justifiable to those seeking access as well as those already resident.
