We wrote an FAQ on Parliamentary Privilege for IBN Live. See http://ibnlive.in.com/news/what-puri-bedi-are-guilty-of-parl-privilege-faqs/179977-37.html The full text is reproduced below. Several MPs have given breach of privilege notices against actor Om Puri and ex-policewoman Kiran Bedi for using "derogatory and defamatory" language against Members of Parliament. In light of this, we explain the concept of breach of privilege and contempt of Parliament. What is parliamentary privilege? Parliamentary privilege refers to rights and immunities enjoyed by Parliament as an institution and MPs in their individual capacity, without which they cannot discharge their functions as entrusted upon them by the Constitution. Are these parliamentary privileges defined under law? According to the Constitution, the powers, privileges and immunities of Parliament and MP's are to be defined by Parliament. No law has so far been enacted in this respect. In the absence of any such law, it continues to be governed by British Parliamentary conventions. What is breach of privilege? A breach of privilege is a violation of any of the privileges of MPs/Parliament. Among other things, any action 'casting reflections' on MPs, parliament or its committees; could be considered breach of privilege. This may include publishing of news items, editorials or statements made in newspaper/magazine/TV interviews or in public speeches. Have there been earlier cases of breach of privilege? There have been several such cases. In 1967, two people were held to be in contempt of Rajya Sabha, for having thrown leaflets from the visitors' gallery. In 1983, one person was held in breach for shouting slogans and throwing chappals from the visitors' gallery. What is the punishment in case of breach of privilege or contempt of the House? The house can ensure attendance of the offending person. The person can be given a warning and let go or be sent to prison as the case may be. In the case of throwing leaflets and chappal, the offending individuals were sentenced to simple imprisonment. In the 2007 case of breach of privilege against Ambassador Ronen Sen, the Lok Sabha Committee on privileges held that the phrase "headless chicken" was not used by Shri Sen in respect of MPs or politicians. No action was taken against him. In 2008, an editor of an Urdu weekly referred to the deputy chairman of Rajya Sabha as a "coward" attributing motives to a decision taken by him. The privileges committee held the editor guilty of breach of privilege. The committee instead of recommending punishment stated that, “it would be better if the House saves its own dignity by not giving undue importance to such irresponsible articles published with the sole intention of gaining cheap publicity.”
The recent 2G-controversy and the related debate over the role of the PAC as opposed to the JPC also raises a broader Issue regarding the general scrutiny of government finances by Parliament. Oversight of the government’s finances involves the scrutiny of the government’s financial proposals and policies. The Indian Constitution vests this power with the Parliament by providing that (a) taxes cannot be imposed or collected without the authority of law, and (b) expenditure cannot be incurred without the authorisation of the legislature. The Indian Parliament exercises financial oversight over the government budget in two stages: (1) at the time of presentation of the annual budget, and (2) reviewing the government’s budget implementation efforts through the year. The Parliament scrutinises the annual budget (a) on the floor of the House, and (b) by the departmentally related standing committees. Scrutiny on the floor of the House The main scrutiny of the budget in the Lok Sabha takes place through: (a) General discussion and voting: The general discussion on the Budget is held on a day subsequent to the presentation of the Budget by the Finance Minister. Discussion at this stage is confined to the general examination of the Budget and policies of taxation expressed during the budget speech. (b) Discussion on Demand for Grants: The general discussion is followed by a discussion on the Demand for Grants of different ministries. A certain number of days or hours are allocated for the discussion of all the demands. However, not all the demands are discussed within the allotted number of days. The remaining undiscussed demands are disposed of by the Speaker after the agreement of the House. This process is known as the ‘Guillotine’. Figure 1 shows the number of Demands discussed and guillotined over the last five years. It shows that nearly 90% of the Demands are not discussed every year. 
Some Important Budget Documents Annual Financial Statement – Statement of the estimated receipts and expenditure of the government. Demand for Grants –Expenditure required to be voted by the Lok Sabha. A separate Demand is required to be presented for each department of the government. Supplementary Demand for Grants – Presented when (a) authorized amounts are insufficient, or (b) need for additional expenditure has arisen. Finance Bill – Details the imposition of taxes, the rates of taxation, and its regulation. Detailed Demand for Grants – Prepared on the basis of the Demand for Grants. These show further break-up of objects by expenditure, and also actual expenditure in the previous year. For more details see detailed note on Financial Oversight by Parliament here.
