Explanation: Parliamentary privileges are special rights, immunities and exemptions enjoyed by the two Houses of Parliament, their committees and their members.

• They are necessary in order to secure the independence and effectiveness of their actions.
• Without these privileges, the Houses can neither maintain their authority, dignity nor honor nor can protect their members from any obstruction in the discharge of their parliamentary responsibilities.
• The Constitution has also extended the parliamentary privileges to those persons who are entitled to speak and take part in the proceedings of a House of Parliament or any of its committees.
• These include the attorney general of India and Union ministers.
