In the late 1960s and 70s, defections (elected legislators changing parties after the election) in Parliament and State Legislatures became very frequent, so frequent in fact, that the epithet "Aaya Ram Gaya Ram" was coined to describe the same.  To curb this problem which created instability in our legislatures, Parliament amended the Constitution.  They inserted the Tenth Schedule to the Constitution "to curb the evil of political defections".  As a result, we currently have an anti-defection law with the following features: 1.  If an MP/MLA who belongs to a political party voluntarily resigns from his party or, disobeys the party "whip" (a direction given by the party to all MPs/ MLAs to vote in a certain manner), he is disqualified.   The party may however condone the MP/ MLA within 15 days. 2.  An independent MP/ MLA cannot join a political party after the election. 3.  An MP/ MLA who is nominated (to the Rajya Sabha or upper houses in state legislatures) can only join a party within 6 months of his election. 4.  Mergers of well-defined groups of individuals or political parties are exempted from disqualification if certain conditions are met. 5.  The decision to disqualify is taken by the Speaker/ Chairman of the House. The table below summarizes provisions of anti-defection law in some other countries.  (For more, click here).  As one may note, a number of developed countries do not have any law to regulate defection.

Recently the Chairman of Rajya Sabha issued a direction to extend the sitting hours and change the timing of Question Hour in the Upper House. Beginning with the Winter Session, which starts on November 24, Rajya Sabha will meet from 11 am to 6 pm, an hour more than its typical sitting hours. Question Hour will be scheduled from 12 pm to 1 pm, which was earlier held in the first hour of meeting. Members of Parliament (MPs), in addition to their legislative capacity, play an important role to keep the government accountable. One mechanism for them to hold the government responsible for its policies and actions is Question Hour in Parliament. During Question Hour, MPs raise questions to Ministers on various policy matters and decisions. Currently, all MPs can submit up to ten questions for every day that Parliament is in Session. Of these, 250 Questions are picked up by a random ballot to be answered each day that Parliament meets. While 230 Questions are answered in writing by Ministries, 20 Questions are scheduled to be answered orally by Ministers on the floor of the House. When a Question is answered orally by a Minister, MPs are also able to ask him/her two Supplementary Questions as a follow up to the response given. Therefore the proper functioning of Question Hour allows Parliament to be effective in its accountability function. Over the years Question Hour has become a major casualty to disruptions in Parliament. The last decade has seen a decline in the number of questions answered orally on the floor of the House. Rajya Sabha had tried to address this problem in 2011, when Question Hour was shifted to be held from 2 pm to 3 pm, but this was discontinued within a few days. Percentage of Questions Answered Orally The 2014 Budget Session saw both Houses of Parliament work for over hundred percent of their scheduled sitting time. However, while Question Hour functioned for 87% of its scheduled time in Lok Sabha, it functioned for only 40% of its scheduled time in Rajya Sabha. In 13 of the 27 sittings of the 2014 Budget Session, Question Hour in Rajya Sabha was adjourned within a few minutes due to disruptions. It was as a result of these increasing disruptions in the Upper House that the change in timing of the Question Hour and extension of its hours of sitting were proposed. While the Rules of Procedures of Rajya Sabha designate the first hour of sitting for Question Hour, they also allow the Chairman of the House to direct otherwise. It is using this Rule that the Chairman of Rajya Sabha, Mr. Hamid Ansari, issued directions for the Question Hour to be shifted to noon. It now remains to be seen whether this change in timing of Question Hour in the Upper House will be sufficient to allow for its smoother functioning. Sources: M.N. Kaul and S.L.
