Simultaneous Elections

Syllabus: GS2/Government Policies and Interventions


  • Former President Ram Nath Kovind, recently said that holding simultaneous elections would benefit the public and whichever party in power at the Centre.


  • He said the revenue saved can be used for development work.
  • The high-level committee, headed by Former President Ram Nath Kovind, was set up by the Law Ministry on September 2, 2023.
    • It will examine and make recommendations for holding simultaneous elections to the Lok Sabha, State Assemblies and local bodies. 

Simultaneous Elections in India (One Nation One Election)

  • Simultaneous Elections refer to the idea of holding Lok Sabha and State legislative assembly elections together, with the aim of reducing the frequency of elections and their associated costs.
  • Simultaneous elections in India to the Lok Sabha and State Legislative Assemblies were held in the years 1951-52, 1957, 1962 and 1967. 
    • Thereafter, the schedule could not be maintained and the elections to the Lok Sabha and the State legislative assembly have still not been realigned.
  • The Election Commission in its annual report (1983) had recommended that a system should be evolved so that elections could be held simultaneously.
  • The Law Commission (170th Report- 1999) stated that we must go back to the past where the elections to Lok Sabha and all the Vidhan Sabha were held simultaneously. 
  • The 79th Report of the Parliamentary Standing Committee (2015) also favored the idea of the simultaneous elections which was reiterated by a NITI Aayog paper in 2017.

Arguments In Favour of One Nation One Election

  • It will reduce the huge expenditure incurred for conducting separate elections every year.
  • The problem of frequent elections leads to imposition of MCC over prolonged periods of time which affects the normal governance. Simultaneous elections can overcome such issues.
  • Simultaneous elections will free the crucial manpower which is often deployed for prolonged periods on election duties
  • The focus on governance will increase, instead of being constantly in election mode.

Arguments Against One Nation One Election:

  • Logistical Challenges: All states and the central government face massive logistical challenges including coordinating the schedules, resources etc.
  • Disadvantage for regional parties: It may help the dominant national party or the incumbent at the Centre at the cost of regional parties and regions issues can be overshadowed by the national issues. 
  • Financial Implications: Conducting elections is expensive and requires significant resources like manpower.
  • Issue of dissolution: Prematurely dissolution on account of a vote of no-confidence becomes difficult to deal with in case simultaneous elections are there.

Way Ahead

  • Considering the fact that frequent elections led to a huge burden on human resources and affected the development process, a sustained debate is required on the subject.
  • All political parties need to arrive at a consensus on the issue of simultaneous elections before taking any step towards it.

Governor’s Power to Withhold Bills

Syllabus: GS2/Structure, organisation and functioning of the Executive


  • The Supreme Court recently held that the Constitution does not provide the Governor of Tamil Nadu any “discretion” to withhold the 10 Bills “repassed” by the State Legislative Assembly.


  • The Bills had been sent for approval to the Governor’s office in the period between January 2020 to April 2023. The State had complained to the court that the Governor was holding them back indefinitely.
  • The Governor had withheld assent and “returned” the Bills to the House only recently on November 13. 
  • The Tamil Nadu Assembly had convened a special session on November 18 to re-pass the Bills and send them back to the Governor for approval.

About the ruling

  • Once they have been re-passed, the Bills are put in the same footing as Money Bills. Then the Governor cannot reject it, said Chief Justice of India D.Y. Chandrachud.
  • The court also acknowledged the State’s submission that the Governor, having withheld assent and sent back the Bills once, cannot refer the reiterated Bills to the President.

Process of granting assent

  • Assent of the Governor is necessary for a Bill passed by the legislature to become law. The Constitution is, however, categorical about Money Bills, which are automatically considered to have a Governor’s assent. 
  • When a Bill passed by both Houses of the Legislature is presented to the Governor for his assent, he is empowered under Article 200 of the Constitution to exercise any of four alternatives:
    • To give assent
    • Withhold assent 
    • Return the Bill to the Legislative Assembly for reconsideration: If the Governor withhold assent, he should return the Bill ‘as soon as possible,’ requesting the Assembly to reconsider the proposed law. 
In Durga Pada Ghosh v. State of West Bengal (1972), the Supreme Court interpreted the phrase ‘as soon as possible,’ to mean “as early as practicable without avoidable delay”. 
  • However, the Assembly is not obligated to accept these recommendations and can pass the Bill again in its original form.
    • This time, the Governor is constitutionally bound to either give assent to it or reserve it for the President’s consideration. 
    • This provision affirms the primacy of the legislature comprising elected representatives of the people over the constitutional head of the State.  
  • Reserve it for the consideration of the President: A Bill can be reserved for the President’s consideration if the Governor is of the opinion that it would endanger the position of the concerned High Court by whittling away its powers.
  • However, there is no timeline prescribed for Governors to make a decision with regard to a Bill. This loophole is often misused to delay legislation — a manoeuvre called a ‘pocket veto’. 
  • Similarly, no timeline has been outlined for the President to decide on the outcome of a Bill.
    • There is, however, a time period of six months prescribed for the State Assembly to reconsider a Bill if the President decides to refer it back to the House.
Related Supreme Court Rulings
– Shamsher Singh v. State of Punjab (1974): Although the Constitution vests the executive power of the State in the Governor, he can act only on the ‘advice’ of the Council of Ministers, with the Chief Minister as the head of the Council.
– Purushothaman Nambudiri v State of Kerala (1962)Since there is no time limit prescribed under Articles 200 for the Governor to give his assent, the Constitution framers did not intend for a Bill pending assent to be at risk of lapsing on dissolution of the House.
– Nabam Rebia and Bamang Felix v. Dy. Speaker (2016): Governor exercises discretion only with regard to whether a Bill ought to be reserved for consideration of the President or not. 
a. It also held that only those matters where the Constitution expressly permits the Governor to act autonomously cannot be challenged before a court of law.

   What needs to be done?

  • The 1988 Sarkaria Commission report on Centre-State relations recommended that delay by Governors in assenting to Bills could be avoided by ensuring that there is prior consultation with the Governor at the stage of the drafting of the Bill itself, and by prescribing time limits for its disposal. 
  • The National Commission to Review the Working of the Constitution2000 reiterated this view by highlighting that there should be a time limit, preferably six months, to give assent or to reserve a Bill for consideration of the President by the Governor and three months within which the President should decide if the Bill is reserved for his consideration.
  • Time and again, the Court has cautioned Governors from indefinitely withholding assent to Bills as it subverts the federal structure and obfuscates governance.

Emissions Gap Report 2023

Syllabus: GS3/Environmental Impact Assessment

In News

  • The United Nations Environment Program (UNEP) has released the 14th edition of Emissions Gap Report 2023.
    • World leaders will soon meet in Dubai for the annual U.N. climate summit COP28 with the aim of keeping the Paris Agreement warming target of 1.5°C alive.

About the Report

  • It is UNEP’s spotlight report launched annually in advance of the annual Climate negotiations. 
  • It tracks the gap between where global emissions are heading with current country commitments and where they ought to be to limit warming to 1.5°C. 
  • Each edition explores ways to bridge the emissions gap.
  • The report assessed countries’ Nationally Determined Contributions (NDCs), which they are required to update every five years, to determine how much the world might warm if these plans were fully implemented.
About The United Nations Environment Program (UNEP)
– It is the leading environmental authority in the United Nations system established in 1972.
– The UN Environment Assembly is the policy-making organ of UNEP.
– Headquarter: Nairobi, Kenya.
– Major Reports: Global Environment Outlook, The Rise of Environmental Crime Report, Actions on Air Quality, Frontiers Report, Adaptation Gap Report.

Major Highlights

  • Increase in Emissions: Global GreenHouse Gases (GHG) emissions increased by 1.2 percent from 2021 to 2022. 
  • Breach of 1.5 Degrees: As many as 86 days this year so far have already breached the 1.5 degree Celsius temperature threshold.
  • Global Emissions Trajectory: Countries’ current emissions pledges to limit climate change would still put the world on track to warm by nearly 3 degrees Celsius this century.
    • The anticipated level of warming is slightly higher than the 2022 projections, which then pointed toward a rise of between 2.4°C and 2.6°C by 2100.
    • Even in the most optimistic emissions scenario, the chance of now limiting warming to 1.5°C is just 14%.
  • Policy Recommendations: The world is heading for a temperature rise far above the Paris Agreement goals unless countries deliver more than they have promised. 
    • Planet-warming greenhouse gas emissions must fall by 42% by 2030 to hold warming at 1.5°C.
  • Conclusion: These findings underline that immediate and unprecedented mitigation action in this decade is essential.
    • Over-complying with current NDC targets for 2030 will enable countries to put forward more ambitious mitigation targets for 2035 in their next NDCs.

India’s Nationally Determined Contribution (NDCs) Goals

  • The 2015 NDC comprised eight goals; three of these have quantitative targets upto 2030 namely:
    • cumulative electric power installed capacity from non-fossil sources to reach 40%; 
    • reduce the emissions intensity of GDP by 33 to 35 percent compared to 2005 levels and;
    • creation of an additional carbon sink of 2.5 to 3 billion tonnes of CO2 equivalent through additional forest and tree cover.
  • As per the updated NDC, India now stands committed to reduce Emissions Intensity of its GDP by 45 percent by 2030, from 2005 level and achieve about 50 percent cumulative electric power installed capacity from non-fossil fuel-based energy resources by 2030.

Gamma-Ray Burst

Syllabus:GS3/Science and Technology


  • A gamma-ray burst (GRB) from a star’s supernova explosion in a galaxy almost two billion light-years away has created disturbance in Earth’s ionosphere.

A Gamma-ray Burst (GRB)

  • It occurs when the core of a massive star runs out of nuclear fuel, collapses under its own weight, and forms a black hole.
  • GRBs that last less than two seconds are caused by the merger of two neutron stars or the merger of a neutron star and a black hole. 
  • Longer GRBs, which can last hours, are triggered when a massive star collapses and births a black hole. 

What is the Ionosphere?

  • The ionosphere is situated about 30-600 miles (50-950 km) above Earth’s surface, stretching to the very edge of space. It contains electrically charged gasses called plasma.
  • The layer helps form the boundary between the vacuum of space and the lower atmosphere inhabited by people and Earth’s other denizens.

Effect of GRB on Ionosphere

  • The gamma rays cause a strong variation in the ionosphere’s electric field. It is similar to the effect which occurs during a solar flare event. 
  • The layer is highly sensitive to changing magnetic and electrical conditions in space, usually connected to solar activity. It also expands and contracts in response to solar radiation.
  • The gamma-ray bursts do not cause deleterious effects for life on Earth. However, it has been hypothesized that a strong one originating within the Milky Way and pointed right at us could pose a danger, including mass extinctions.
