• Statement 1 is not correct: This limitation is imposed only on criminal laws and not on civil laws or tax laws. In other words, civil liability or a tax can be imposed retrospectively. 

• Statement 2 is not correct: Protection against self-incrimination does not extend to (i) compulsory production of material objects, (ii) compulsion to give thumb impression, specimen signature, blood specimens, and (iii) compulsory exhibition of the body. 

• Statement 3 is not correct: Protection against double jeopardy is available only in proceedings before a court of law or a judicial tribunal. In other words, it is not available in proceedings before departmental or administrative authorities as they are not of judicial nature.
