This document discusses the principles of natural justice and abuse of administrative discretion in administrative law. It begins by introducing natural justice as a principle that gives people the right to raise their voice against injustice and prove their case in court. It then defines natural justice and explores its origins in Roman and Greek civilizations. The two main principles of natural justice discussed are nemo iudex in parte sua (no one should be the judge in their own case) and audi alteram partem (listen to the other side). The document examines these principles in depth through case law examples and rules for their application. It then defines administrative discretion and explores its potential for abuse if powers are incorrectly exercised without following statutory requirements or if irrelevant considerations are taken
