Rule No 222 in Chapter 20 of the Lok Sabha Rule Book and correspondingly Rule 187 in Chapter 16 of the Rajya Sabha rulebook governs privilege. It says that a member may, with the consent of the Speaker or the Chairperson,
raise a question involving a breach of privilege either of a member or of the House or of a committee thereof. The rules however mandate that any notice should be relating to an incident of recent occurrence and should need the intervention of the House.

The functions of the estimates committee are:
1. To report what economies, improvements in organisation, efficiency and administrative reform consistent with the policy underlying the estimates, can be affected.
2. To suggest alternative policies in order to bring about efficiency and economy in administration
3. To examine whether the money is well laid out within the limits of the policy implied in the estimates
4. To suggest the form in which the estimates are to be presented to Parliament.
However, the effectiveness of the role of the committee is limited by the following:

(b) It cannot question the policy laid down by the Parliament.
(c) Its recommendations are advisory and not binding on the ministries.
(d) It examines every year only certain selected ministries and departments. Thus, by rotation, it would cover allof them over a number of years.

(f) Its work is in the nature of a post-mortem.
