Wat is a fair trial????

Posted by Tejasvini Sri 7 years ago

CBSE > Class 08 > Social Science

1 answers

Yogita Ingle 7 years ago

Article 21 of the Constitution, that guarantees the Right to Life, states that a person’s life or liberty can be taken away only by following a reasonable and just legal procedure. A fair trial ensures that Article 21 of the Constitution is upheld. The Constitution and the law both state that all of the persons should carry out their roles in a proper manner. What this means is that they all need to work to ensure that every citizen, irrespective of their class, caste, gender, religious and ideological backgrounds gets a fair trial when accused. The rule of law which says that everyone is equal before the law would not make much sense if every citizen were not guaranteed a fair trial by the Constitution.
