If there is any offending part in a statute, then, only the offending part is declared void and not the entire statute. This is the core theme of

Doctrine of Severability It is also known as the doctrine of separability and protects the Fundamental Rights of the citizens. •According to this doctrine, if there is any offending part in a statute, then, only the offending part is declared void and not the entire statute. •When  invalid  part  can  be  severed  from  the  enactment,  the  whole  law/act  would  not  be held invalid, but only the provisions which are inconsistent with the Fundamental Rights. In case such severance is not possible, the whole act will be held invalid. •As per clause (1) of the Article 13 of the Constitution, if any of the laws enforced in India are inconsistent with the provisions of fundamental rights, they shall, to the extent of that inconsistency, be void. •The whole law/act would not be held invalid, but only the provisions which are not in consistency with the Fundamental rights
