Attorney General and Solicitor General’s Roles in Indian Parliament

The Attorney General of India is often mistaken to have the same parliamentary privileges as the Solicitor General of India. However, this is not the case. The Attorney General has the unique right to participate in the proceedings of the Parliament of India, as stated in Article 88 of the Indian Constitution. This includes the right to speak in both Houses of Parliament and any committee meetings, though without a right to vote. On the other hand, the Solicitor General, who assists the Attorney General, does not possess these rights.

Resignation of the Attorney General of India

Another common misconception is regarding the resignation of the Attorney General. According to Article 76 of the Indian Constitution, the Attorney General holds office at the pleasure of the President and is not constitutionally required to resign when the appointing government resigns or is replaced. While it is conventional for the Attorney General to resign in such circumstances, it is not mandated by the Constitution.
