The United Nations Convention on the Rights of the Child 1989 is one of the most highly ratified human rights treaties in the world, with 192 states currently signed up to it. Article Twelve is fundamental to the Convention and states that all children capable of forming views have the right to express those views, and recognises that all children have the right to be heard in any judicial and administrative proceedings affecting them.

This book explores the historical and theoretical background to Article Twelve, and examines the various models of participation which have been created to facilitate a better understanding of this provision. Aisling Parkes analyzes the extent to which Article Twelve has been implemented under international law, and in domestic law, as well as setting-out recommendations for the most effective ways of implementing Article Twelve in all areas of children's lives.
