Which of the following statements about Article 20(1) of the Constitution of India is/are correct? 1. It contains a provision against ex post facto legislation. 2. A legislation shall not be competent to make a criminal law retrospective. Select the answer using the code given below.

  1. A.1 only
  2. B.2 only
  3. C.Both 1 and 2
  4. D.Neither 1 nor 2

Correct answer

C. Both 1 and 2

Explanation

The correct answer is C, Both 1 and 2. Article 20(1) bars ex post facto criminal laws, so a legislature cannot make a criminal law apply retrospectively.

Article 20 gives protection in respect of conviction for offences. Clause (1) says no person shall be convicted of an offence except for violating a law in force when the act was done, nor be given a penalty greater than the one in force at that time. This is the protection against ex post facto laws. The bar applies only to criminal laws: civil liability or a tax can still be imposed with retrospective effect. It also covers only conviction and sentence, not trial procedure. Clause (2) bars double jeopardy and clause (3) bars self-incrimination; Article 20 cannot be suspended even during an Emergency.

A is wrong: statement 2 is also correct, since it states the effect of the same clause.

B is wrong: statement 1 is the core of Article 20(1).

D is wrong: both statements are correct.

Exam tip: Article 20 = (1) no ex post facto criminal law, (2) no double jeopardy, (3) no self-incrimination.
