Phase IFoundation

Background

Overview

UPSC examines the Indian legal system, fundamental rights, judicial processes, and the balance between national security and individual liberties. Understanding principles of fair trial and evidence admissibility is crucial for evaluating the effectiveness and fairness of the criminal justice system.

The principle of fair trial is a cornerstone of democratic justice systems, ensuring that every individual accused of a crime receives a just and impartial hearing. A critical component of a fair trial is the strict adherence to rules governing the admissibility of evidence, particularly confessions, to prevent convictions based on coerced statements or evidence obtained in violation of fundamental rights.
