Explanation:

 Fundamental right which is guaranteed under Article 20(2) of Constitution of India incorporates the principles of  “autrefois convict” or Double jeopardy which means that person must not be punished twice for the offence. Doctrine against Double Jeopardy embodies in English common law’s maxim ‘nemo debet bis vexari, si constat curice quod sit pro una iti eadem causa” (no man shall be punished twice, if it appears to the court that it is for one and the same cause). It also follows the “audi alterum partem rule” which means that no person can be punished for the same offence more than ones. And if a person is punished twice for the same offence it is termed Double jeopardy.
