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.

Sakshi of PRS Legislative Research discusses the government's ordinance-making power in the context of the National Food Security Ordinance in an Indian Express opinion editorial. On Wednesday, the Union cabinet approved the food security ordinance. The government has already introduced a National Food Security Bill in Parliament in December 2011. Parliamentary consideration on the bill has been initiated with the standing committee submitting its recommendations and the government proposing amendments to the law. After being listed on several occasions for discussion, members of Parliament began debating the bill in the last few days of the 2013 budget session. In spite of all this, the government has chosen to promulgate an ordinance. In all likelihood, Parliament will reconvene in a few weeks for the monsoon session. In this context, it would be useful to understand the ordinance-making power of government and its usage in the recent past. Under the Constitution, the power to make laws rests with the legislature. The executive has been given the power to make laws when Parliament is not in session and "immediate action" is necessary. In such scenarios, the president can issue an ordinance on the advice of the executive, to have the same effect as an act of Parliament. In the 1980s, the Supreme Court was confronted with a case where a state government repeatedly re-promulgated ordinances that had lapsed in previous assembly sessions. This led the SC to examine the ordinance-making power of government. The SC reasserted the constitutional principle that the primary law-making power rests with the legislature and not the executive. The executive is only given the legislative power to issue an ordinance to meet an "emergent situation". Such a situation arose in 2011 when, given that students were awaiting their degrees on the completion of their course, the government issued an ordinance to grant IIIT-Kancheepuram the status of an institute of national importance so that students could be awarded their degrees. Data over the last 60 years indicates that the highest number of ordinances, 34, were passed in 1993. Over the 15th Lok Sabha (2009-2013), there have been 16 ordinances, indicating a decline in the number of ordinances being issued every year. Once an ordinance is framed, it is to be laid before Parliament within six weeks of its first sitting. Parliament is empowered to either choose to pass the ordinance as law or let it lapse. Once the ordinance is laid in Parliament, the government introduces a bill addressing the same issue. This is typically accompanied by a memorandum tabled by the government, explaining the emergent circumstances that required the issue of an ordinance. Thereafter, the bill follows the regular law-making process. If Parliament does not approve the ordinance, it ceases to exist. The drafters of the Constitution created this check on the law-making power of the executive to reinforce the notion that law-making will remain the prerogative of the legislature. Earlier this year, in the aftermath of the Delhi gangrape, public pressure led the government to appoint a three-member committee under the late Justice J.S. Verma to suggest changes to laws relating to crimes against women. An amendment bill had already been pending in Parliament. In spite of this, the government brought in the Criminal Law Ordinance, giving effect to some of the committee's recommendations. Once Parliament reconvened, the government introduced a fresh bill replacing the ordinance, seeking to create more stringent provisions on matters related to sexual offences. It passed muster in both Houses. While the Criminal Law Ordinance is an illustration of an ordinance successfully passing through Parliament, there are examples of ordinances that have lapsed because they were not approved by Parliament. In 2004, a week after the winter session ended, the government issued an ordinance to give the Pension Fund Regulatory and Development Authority statutory powers as a regulator. Due to political opposition, the ordinance lapsed and, subsequently, the bill lapsed at the end of the 14th Lok Sabha. The government re-introduced it as a bill in 2011, which is currently pending in Parliament. Although the government has used its power to issue a food security ordinance, the law guaranteeing this right will have to stand scrutiny in Parliament. What remains to be seen is how Parliament debates the right to food in the upcoming monsoon session. That should give us some food for thought.
