Article 20 stands as one of the fundamental safeguards within the Indian Constitution, providing essential protection to individuals against arbitrary criminal laws and prosecution. Embedded in Part III—often referred to as the heart and soul of the Constitution—this article reflects India’s commitment to justice, human rights, and the rule of law. Designed immediately after independence, Article 20 specifically addresses concerns over unjust criminal prosecution, having profound implications for how justice is administered in contemporary India.
The main objective of Article 20 is to protect individuals, particularly those accused or convicted of crimes, from excesses of state power. It comprises three significant clauses:
Article 20(1) stipulates that no one can be convicted for any act that was not a crime at the time it was committed. Furthermore, it bars the imposition of greater punishment than what was applicable when the offense was committed.
Article 20(2) states that no person shall be prosecuted and punished for the same offense more than once. This is analogous to the principle of “double jeopardy” recognized worldwide.
Article 20(3) provides that no person accused of any offense shall be compelled to be a witness against themselves. This is often summarized as the “right to silence.”
“Article 20 of our Constitution seeks to ensure that individual liberty does not become a mere phrase in the face of state power—especially for those accused of criminal conduct.”
— Justice V.R. Krishna Iyer, Supreme Court of India
Beyond the letter of the law, Article 20 represents a commitment to democratic values. The drafters of the Indian Constitution were acutely aware of global contexts—especially the excesses witnessed during colonial rule and in other authoritarian regimes, where retroactive laws and coerced confessions were not uncommon.
The principles enshrined in Article 20 have parallels with international conventions such as the Universal Declaration of Human Rights (UDHR) and the International Covenant on Civil and Political Rights (ICCPR):
Understanding Article 20’s nuances requires examining how its provisions play out in India’s legal and social landscape.
In Kedar Nath v. State of West Bengal, the Supreme Court clarified that Article 20(1) prohibits only conviction and sentence under ex-post facto criminal law. However, a retrospective legislation that reduces punishment can apply, as it benefits the accused.
The Nandini Satpathy v. P.L. Dani judgment fundamentally shaped India’s approach to self-incrimination. The court found that even compelled signatures or forced answers during investigation count as violations unless given voluntarily.
While Article 20 is robust, its application isn’t without challenges.
Legal scholars occasionally argue that Article 20 should evolve to address contemporary challenges—such as digital crimes, preventive detention laws, or the use of new forms of evidence. Furthermore, ensuring legal aid for the underprivileged remains a core issue.
Securing justice requires not only legal provisions but also widespread public understanding. For many in India, especially those who are Hindi-speaking or lack legal literacy, awareness of Article 20 in Hindi makes the provisions accessible.
Article 20 remains a cornerstone of India’s criminal jurisprudence and civil liberties protection. By preventing retrospective punishment, safeguarding against double jeopardy, and protecting the accused from self-incrimination, it balances the needs of justice with fundamental fairness. However, the true power of Article 20 lies not simply in its text, but in its recognition, implementation, and accessibility to every Indian, regardless of language or background. Ongoing efforts to translate and disseminate these legal rights in widely understood languages like Hindi are crucial steps toward deeper democratic participation and trust in the rule of law.
Article 20 protects individuals from retroactive criminal laws, prevents double punishment for the same offense, and grants the right against self-incrimination.
It applies to criminal offenses and prosecutions, but not to civil or administrative matters. Its protections also remain active during emergencies under the Indian Constitution.
No, Article 20(3) safeguards the accused from being compelled to provide self-incriminating evidence or testimony.
While the principles are globally recognized, India’s Article 20 is unique in its explicit inclusion in the Constitution and in its application, irrespective of a declared emergency.
Translating Article 20 into Hindi and other regional languages ensures broader awareness and empowers citizens, especially those who do not read English, to understand and exercise their legal rights.
Yes, if a new law reduces the punishment for an offense, it may apply retroactively to benefit the accused, as clarified by Indian courts. However, harsher punishments cannot be enforced retroactively.
