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.”
Parliament sessions are usually held thrice a year: once in February for the Budget Session, once around July or August for the Monsoon Session, and once in November for the Winter Session. This year, the government is yet to announce the dates for the Winter Session. While there has been uncertainty around whether Parliament will meet, ministers in the government have indicated that the Session will be held soon.[1]
The practice of allowing the government to convene Parliament differs from those followed in other countries. Some of these countries have a limited role for the government in summoning the legislature, because in a parliamentary democracy the executive is accountable to Parliament. Allowing the government to call the Parliament to meet could be in conflict with this principle. While we wait for the government to announce the dates for the Winter Session, this post looks at the relationship between Parliament and the government, recommendations made over the years on improving some parliamentary customs, and discusses certain practices followed by other countries.
What is the role of Parliament in a democracy?
The Constitution provides for the legislature to make laws, the government to implement laws, and the courts to interpret and enforce these laws. While the judiciary is independent from the other two branches, the government is formed with the support of a majority of members in the legislature. Therefore, the government is collectively responsible to Parliament for its actions. This implies that Parliament (i.e. Lok Sabha and Rajya Sabha) can hold the government accountable for its decisions, and scrutinise its functioning. This may be done using various methods including, during debates on Bills or issues on the floor of Parliament, by posing questions to ministers during Question Hour, and in parliamentary committees.
Who convenes Parliament?
Parliament must be convened by the President at least once in every six months. Since the President acts on the advice of the central government, the duration of the session is decided by the government.
Given the legislature’s role in keeping the executive accountable for its actions, one argument is that the government should not have the power to convene Parliament. Instead, Parliament should convene itself, if a certain number of MPs agree, so that it can effectively exercise its oversight functions and address issues without delay. Some countries such as the United Kingdom and Australia release an annual calendar with the sitting dates at the beginning of the year.
How regularly has Parliament been meeting over the years?
Over the years, there has been a decline in the sitting days of Parliament. While Lok Sabha met for an average of 130 days in a year during the 1950s, these sittings came down to 70 days in the 2000s. Lesser number of sittings indicates that Parliament was able to transact less business compared to previous years. To address this, the National Commission to Review the Working of the Constitution has recommended that Lok Sabha should have at least 120 sittings in a year, while Rajya Sabha should have 100 sittings.[2] 
The Constituent Assembly, while drafting the Constitution had debated the power that should be given to Parliament with regard to convening itself. Mr. K. T. Shah, a member of the Assembly, had suggested that in case the President or the Prime Minister are unable or unwilling to call for a Parliament session, the power to convene the Houses should be given to the presiding officers of those Houses (i.e., the Chairman of Rajya Sabha and the Speaker of Lok Sabha). In addition, he had also suggested that Parliament should itself regulate its procedure, sittings and timings.[3]
How does Parliament hold the government accountable?
One of the forums of holding the government accountable for its actions is the Question Hour. During Question Hour, MPs may pose questions to ministers related to the implementation of laws and policies by the government.
In the 16th Lok Sabha, question hour has functioned in Lok Sabha for 77% of the scheduled time, while in Rajya Sabha it has functioned for 47%. A lower rate of functioning reflects time lost due to disruptions which reduces the number of questions that may be answered orally. While Parliament may sit for extra hours to transact other business, time lost during Question Hour is not made up. Consequently, this time lost indicates a lost opportunity to hold the government accountable for its actions.
Further, there is no mechanism currently for answering questions which require inter-ministerial expertise or relate to broader government policy. Since the Prime Minister does not answer questions other than the ones pertaining to his ministries, such questions may either not get adequately addressed or remain unanswered. In countries such as the UK, the Prime Minister’s Question Time is conducted on a weekly basis. During the 30 minutes the Prime Minister answers questions posed by various MPs. These questions relate to broader government policies, engagements, and issues affecting the country.[4]
How is public opinion reflected in Parliament?
MPs may raise issues of public importance in Parliament, and examine the government’s response to problems being faced by citizens through: (i) a debate, which entails a reply by the concerned minister, or (ii) a motion which entails a vote. The time allocated for discussing some of these debates or Bills is determined by the Business Advisory Committee of the House, consisting of members from both the ruling and opposition parties.
Using these methods, MPs may discuss important matters, policies, and topical issues. The concerned minister while replying to the debate may make assurances to the House regarding steps that will be taken to address the situation. As of August 2017, 50% of the assurances made in the 16th Lok Sabha have been implemented.[5] 
Alternatively, MPs may move a motion for: (i) discussing important issues (such as inflation, drought, and corruption), (ii) adjournment of business in a House in order to express displeasure over a government policy, or (iii) expressing no confidence in the government leading to its resignation. The 16thLok Sabha has only discussed one adjournment motion so far.
To improve government accountability in Parliament, the opposition in some countries such as the UK, Canada, and Australia forms a shadow cabinet.[6],[7] Under such a system, opposition MPs track a certain portfolio, scrutinise its performance and suggest alternate programs. This allows for detailed tracking and scrutiny of ministries, and assists MPs in making constructive suggestions. Some of these countries also provide for days when the opposition parties decide the agenda for Parliament.
