Article 20(1) of the Indian Constitution prohibits Ex Post Facto laws. The expression Ex Post Facto Law means a law, which imposes penalties or convictions on the acts already done and increases the penalty for such acts. In other words, Ex Post Facto Law, imposes penalties retrospectively. For example, The Dowry Prohibition Act, 1961 came into force from 20.5.1961. A person guilty of accepting dowry is punishable under the Act after 20.5.1961 and not before 20.5.1961. 
Ex post facto laws are of three kinds as follows:(a) A law which declared some act or omission as an offence for the first time after the completion of that act or omission. (b) A law which enhances the punishment or penalty for an offence subsequent to the commission of that offence. (c) A law which prescribes a new and different procedure for the prosecution of an offence subsequent to the commission of that offence.
Clause (1) of Art. 20 provides protection only in respect of the above first two categories of expost facto laws i.e. laws which declare acts as offences subsequent to the commission to those acts and laws which enhance the penalty subsequently.
Article 20(1) provides: No person shall be convicted of any offence except for violation of a law in force at the time of the commission of the act charged as an offence, nor be subjected to a penalty greater than that which might have been inflicted under the law in force at the time of the commission of the offence. The first part of clause (1) provides that no person shall be convicted of any offence except for violation of law in force at the time of the commission of the act charged as an offence. The second part of clause (1) protects a person form a penalty greater than that which he might have been subjected to at the time of the commission of the offence.
Q. Considering the fact situations given in the above question, the Parliament passes a legislation in September 2020, whereby an amendment is made to the Juvenile Act and now a person below the age of 20 would be a Juvenile and special procedure would be followed for his trial. Choose the most appropriate option amongst the following
  • a)
    Mr. A would not be considered as juvenile as it is prohibited under the scheme of Article 20 (1)
  • b)
    Mr. A would not be considered as juvenile because the amendment came after he committed the offence
  • c)
    Mr. A would be considered a Juvenile and tried under the new procedure
  • d)
    None of the above
Correct answer is option 'C'. Can you explain this answer?
Most Upvoted Answer
Article 20(1) of the Indian Constitution prohibits Ex Post Facto laws....
Explanation:

Background:
Ex post facto laws are prohibited under Article 20(1) of the Indian Constitution.

Amendment to the Juvenile Act:
- In September 2020, an amendment was made to the Juvenile Act, stating that a person below the age of 20 would now be considered a juvenile and a special procedure would be followed for their trial.

Analysis:
- Since the amendment came after the commission of the offense by Mr. A, it falls under the category of an ex post facto law.
- However, Article 20(1) only prohibits ex post facto laws that declare acts as offenses or enhance penalties after the act has been committed.
- The amendment to the Juvenile Act does not fall under either of these categories.
- The amendment simply changes the definition of a juvenile and the procedure for their trial, which does not impose a penalty retrospectively.

Conclusion:
- Mr. A would be considered a juvenile and tried under the new procedure as the amendment does not violate the provisions of Article 20(1) of the Indian Constitution.
