Internal Security Architecture: Centre-State Coordination

Introduction

India's internal security apparatus is characterised by a federal structure where 'Police' and 'Public Order' are State subjects under the Seventh Schedule (List II, Entry 1 & 2), while the Centre retains substantial powers through Union List entries (List I, Entry 1 - Defence; Entry 2-A - Deployment of armed forces; Entry 8 - Preventive detention for security purposes) and Concurrent List entries. This creates a complex coordination challenge.
