Question and Answer

SRIRAM'S IAS

 Q. 133. Rubella, pneumonia now in vaccine cover
Ans. What is Rubella?
Rubella is an acute, contagious viral infection. While the illness is generally mild in children, it has serious consequences in pregnant women causing foetal death or congenital defects known as congenital rubella syndrome (CRS). The rubella virus is transmitted by airborne droplets when infected people sneeze or cough. Humans are the only known host.
 
What is pneumonia?
Pneumonia is a form of acute respiratory infection that affects the lungs. The lungs are made up of small sacs called alveoli, which fill with air when a healthy person breathes. When an individual has pneumonia, the alveoli are filled with pus and fluid, which makes breathing painful and limits oxygen intake. Pneumonia is the single largest infectious cause of death in children worldwide. 
 
Why these are in news?
Pushing forward in its drive against vaccine-preventable diseases, the government is set to introduce two new vaccines -against pneumonia and rubella -under its universal immunisation programme in early 2017.
 
The move assumes significance as it is expected to reduce deaths by almost 20-25% among children under five years of age. India's current under-five mortality rate is around 45 deaths per 1,000 live births.
 
While India has the highest number of pneumonia and diarrhoea deaths among children with nearly 3 lakh children dying in 2016, Rubella is considered a major reason behind the birth of children with deformities. Official estimates show pneumonia alone accounts for 8-10% of the under-five mortality.
Currently, the government's immunisation programme provides cover against around 10 vaccine preventable diseases. The fast ramping up of the programme along with its coverage has been acknowledged globally.
 
Diseases Protected by Vaccination under Immunization program: Diphtheria, Pertussis, Tetanus, Polio, Tuberculosis, Measles, Hepatitis B, Japanese Encephalitis (commonly known as brain fever), Meningitis and Pneumonia caused by Haemophilus Influenza type b.
 Q. 132. Darknet
Ans.
What Is the Darknet?
It is sometimes confused with the deep web, a term that refers to all parts of the Internet which cannot be indexed by search engines and so can't be found through Google, Bing, Yahoo, and so forth. Experts believe that the deep web is hundreds of times larger than the surface web (i.e., the Internet you get to via browsers and search engines).
In fact, most of the deep web contains nothing sinister whatsoever. It includes large databases, libraries, and members-only websites that are not available to the general public. The dark web (or dark net) is a small part of the deep web. Its contents are not accessible through search engines, but it's something more: it is the anonymous Internet. Within the dark net, both web surfers and website publishers are entirely anonymous. Whilst large government agencies are theoretically able to track some people within this anonymous space, it is very difficult, requires a huge amount of resources, and isn't always successful.
Anonymous Communication
Darknet anonymity is usually achieved using an onion network. Normally, when accessing the pedestrian Internet, your computer directly accesses the server hosting the website you are visiting. In an onion network, this direct link is broken, and the data is instead bounced around a number of intermediaries before reaching its destination. The communication registers on the network, but the transport medium is prevented from knowing who is doing the communication.
Who Uses the Darknet?
Military, government, and law enforcement organisations are still amongst the main users of the hidden Internet. This is because ordinary internet browsing can reveal your location, and even if the content of your communications is well-encrypted, people can still easily see who is talking to whom and potentially where they are located. For soldiers and agents in the field, politicians conducting secret negotiations, and in many other circumstances, this presents an unacceptable security risk.
The darknet is also popular amongst journalists and political bloggers, especially those living in countries where censorship and political imprisonment are commonplace. Online anonymity allows these people, as well as whistleblowers and information-leakers, to communicate with sources and publish information freely without fear of retribution. The same anonymity can also be used by news readers to access information on the surface web which is normally blocked by national firewalls, such as the 'great firewall of China' which restricts which websites Chinese Internet users are able to visit.
Accessing the Darknet
The most popular way to do it is using a service called Tor (or TOR), which stands for The Onion Router. Although technically-savvy users can find a multitude of different ways to configure and use Tor, it can also be as simple as installing a new browser. The Tor browser can be used to surf the surface web anonymously, giving the user added protection against everything from hackers to government spying to corporate data collection. It also lets you visit websites published anonymously on the Tor network, which are inaccessible to people not using Tor. This is one of the largest and most popular sections of the darknet.
 Q. 131. Cyclone Global Navigation Satellite System (CYGNSS)
Ans. What is CYGNSS?
The Cyclone Global Navigation Satellite System (CYGNSS) is a space-based system developed by the University of Michigan and Southwest Research Institute with the aim of improving hurricane forecasting by better understanding the interactions between the sea and the air near the core of a storm.
 The Science of CYGNSS
The same GPS technology that helps people get where they're going in a car will soon be used in space to impact hurricane forecasting. The technology is a key capability in a NASA mission called the Cyclone Global Navigation Satellite System (CYGNSS).
The CYGNSS mission will use eight micro-satellites to measure wind speeds over Earth's oceans, increasing the ability of scientists to understand and predict hurricanes. Each satellite will take information based on the signals from four GPS satellites.
 
​CYGNSS is taking a novel approach to calculate wind speeds that both reduces the mission's cost and gathers more data as well.
Typically, measuring wind speed over the oceans from space uses a technique called scatterometry. A radar instrument aboard a satellite sends a signal to the ground, and measures the signal strength reflected back to it. Building both sending and receiving capabilities into a single instrument, however, is more expensive than the method being used on CYGNSS.
The CYGNSS satellites will only receive signals broadcast to them from GPS satellites already orbiting the Earth and the reflection of the same satellite’s signal reflected from the earth. The CYGNSS satellites themselves will not broadcast, that will result in significant cost savings.
 
Better coverage
The use of eight satellites will also increase the area on Earth that can be measured. The instruments will be deployed separately around the planet, with successive satellites passing over the same region every 12 minutes. As the CYGNSS and GPS constellations move around the earth, the interaction of the two systems will result in a  new image of wind speed over the entire tropics every few hours, compared to every few days  for a single satellite.
Another advantage – the CYGNSS orbit is designed to measure only in the tropics, where hurricanes are most often found. Traditional polar-orbiting  weather satellites measure the whole globe because they are trying to capture all types of data. The focus on tropical activity means the CYGNSS instruments will be able to gather that much more useful data on weather systems exclusively found in the tropics.
Science goal
The CYGNSS science goal is to understand the coupling between ocean surface properties, moist atmospheric thermodynamics, radiation, and convective dynamics in the inner core of a tropical cyclone. To achieve this goal, the system will measure ocean surface wind speed in all precipitating conditions, including those experienced in the eyewall. The mission will also measure ocean surface wind speed in the storm's inner core with sufficient frequency to resolve genesis and rapid intensification. As secondary goal, the project will support the operational hurricane forecast community by producing and providing ocean surface wind speed data products. 
 Q. 130. Take any two contemporary laws in India and show how the presence of their subject matter in the Concurrent List contributes to sound public policy.
Ans.
India is a federal form of government and because labour is a subject in the Concurrent List of the Indian Constitution, labour matters are in the jurisdiction of both central and state governments. Both central and state governments have enacted laws on labour relations and employment issues. The advantages with placing a subject in the Concurrent List is that it has national orientation and at the same time has regional flexibility. While the federal law sets standards, states can have their own local variations. Thus, competitive federalism works well. For example, labour legislation. It may not be feasible  to liberalise the labour law for the whole country but states can do so if they have compelling advantages. Rajasthan government did it and was followed by the Madhya Pradesh government. Government of Rajasthan reformed  three labour laws: Industrial Disputes Act, 1947, the Contract Labour Act, 1970 and the Factories Act, 1947.

It attracts investment, creates jobs and prosperity. Similarly, Umnion Legislature enacted Right to Fair Compensation and Transparency in Land Acquisition, Rehabilitation and Resettlement Act, 2013. It protects land owners when they sell land for any public purpose. However, some states have resented rigidities. Tamil Nadu amended it to suit its own conditions in 2015. Thus, land acquisition being a Concurrent subject helps in making sound public policy at the national and state level.
 Q. 129. Global Land Ice Velocity Extraction project (GoLIVE)
Ans.
Scientists have a new tool to systematically track the evolution of glaciers and ice sheets as the climate warms. The US$1-million system, which is funded by NASA and uses data from the Landsat 8 satellite will do that.

The Global Land Ice Velocity Extraction project (GoLIVE) is the first to provide scientists with regular, semi-automated measurements of ice movement across the entire world. Landsat covers the planet every 16 days, and by comparing landmarks and subtle features in ice from one image to another, researchers are able to trace the flow of ice over weeks, seasons and years.

Scientists have been using satellite imagery and radar to track the movement and evolution of glaciers from space for decades, but until now, doing so has required painstaking analysis. Advances in satellite technology, computer algorithms and processing power are now enabling them to expand their reach.

The goal is to understand how quickly glaciers and ice sheets will melt — and consequently how fast oceans will rise — as temperatures increase. Similar efforts to build a record of ice flow are underway for Greenland and Antarctica; these use data from multiple satellites, including visual imagery from Landsat 8 and the European Sentinel 1 satellites.

Eyes in the sky

But some scientists think that radar will ultimately prevail because, unlike visible-light satellite imagery, it can track ice through clouds and at night. This is particularly important in places such as Greenland and Antarctica, where the bulk of the world’s ice is shrouded in complete darkness for much of the winter.

 Q. 126. The Climate Change Performance Index 2017
Ans.
Under the Paris Agreement, climate action was anchored in the context of international law. This requires countries to make their own unique contribution to the prevention of dangerous climate change. The next crucial step to follow this agreement is the rapid implementation by the signing parties of concrete measures to make their individual contributions to the global goal. For the past 12 years, the Climate Change Performance Index (CCPI) has been keeping track of countries’ efforts in combating climate change. The varying initial positions, interests and strategies of the numerous countries make it difficult to distinguish their strengths and weaknesses and the CCPI has been an important tool in contributing to a clearer understanding of national and international climate policy. India ranks 20th among 58 countries on the 2017 Climate Change Performance Index (CCPI). The index is released by Germanwatch, an independent German NGO and Climate Action Network Europe.

Highlights of 2017 CCPI 
  1. First three spots with rating “Very good” has been left blank.
  2. France is ranked 4th in the list.
  3. Saudi Arabia is the worst performer at 61st position.
  4. USA: 43; China 48
  5. Report points out , for a stable decarbonisation of the global energy sector, two components play a crucial role: A shift from fossil fuels to renewable energy and an increase in energy efficiency. In both of these areas, positive developments can already be observed.
 Q. 125. What is Brown Carbon (BrC)? Why it is in news?
Ans. Among the many contributors to climate change are aerosols in the atmosphere. These tiny particles suspended in the air come from many sources, some natural and some man-made. Some aerosols are organic (containing carbon), while others are inorganic. Most aerosols reflect sunlight, and some also absorb it. Many of these nanoparticles have severe health effects in addition to climate effects.

Black carbon  particles (a component of soot) originating from combustion processes have been known for some time to absorb sunlight and warm the atmosphere.
More recently, “brown carbon” (light-absorbing organic carbon) has attracted interest as a possible cause of climate change. This class of organic carbon, known for its light brownish color, absorbs strongly in the ultraviolet wavelengths and less significantly going into the visible. Types of brown carbon include tar materials from smoldering fires or coal combustion, breakdown products from biomass burning, a mixture of organic compounds emitted from soil, and volatile organic compounds given off by vegetation.
Brown carbon contributes +0.25 W m-2 or about 19% of the total atmospheric absorption by anthropogenic aerosols, while 72% is attributed to black carbon and 9% is due to the coating effect of sulfate and organic aerosols on black carbon. Brown carbon needs to be considered in global climate simulations.
 
A study of IIT Kanpur has highlighted that Brown Carbon has the potential to warm atmosphere by absorbing light. When compared to Black Carbon, Brown Carbon has 10 times more mass; Black Carbon has 50 times more absorption capacity than BrC. Both of them are absorbers, contributing in the warming of atmosphere. 
 Q. 124. What is Hyperloop? How does it work? What speeds are proposed?
Ans.
Hyperloop is a proposed mode of passenger and freight transportation that propels a pod-like vehicle through a near-vacuum tube at airline speeds. The pods accelerate to cruising speed gradually using a linear electric motor and glide above their track using passive magnetic levitation or air bearings. The tubes can go above ground on columns or underground, eliminating the dangers of grade crossings. It is hoped that the system will be highly energy-efficient, quiet and autonomous. Tesla and SpaceX's Elon Musk has started the building revolution for this new train system dubbed Hyperloop. It will mean getting from LA to San Francisco in under 30 minutes.

It's based on the very high speed transit (VHST) system proposed in 1972 which combines a magnetic levitation train and a low pressure transit tube. It evolves some of the original ideas of VHST, but still uses tunnels and pods or capsules to move from place to place. One of the biggest problems with anything moving, is friction, both against surfaces and the environment the pod is moving through. Hyperloop proposes to move away from traditional wheels by using air bearings for pods instead. This will have the pod floating on air. It's similar to maglev in which the electromagnetic levitation of the train means there is no friction like a traditional train that runs on tracks. This is how current maglev trains can achieve super speeds, like the 500km/h maglev train in Japan. The Hyperloop will be built in tunnels that have had some of the air sucked out to lower the pressure. So, like high altitude flying, there's less resistance against the pod moving through the tunnel, meaning it can be much more energy efficient, something that's highly desirable in any transit system.

Hyperloop is being proposed as an alternative to short distance air travel, where the system will be much faster than existing rail networks and much cleaner that flight. Speeds of over 700mph are suggested for journeys, but there are practical implications that have to be considered on a short stop-start journey, such as the acceleration and deceleration sensation that passengers would go through. 
 Q. 123. The National Commission for Women was set up more than two decades ago with what objectives? Has it lived upto the promise?
Ans. The National Commission for Women was set up as statutory body in 1992 to:
  • review the Constitutional and Legal safeguards for women ;
  • recommend remedial legislative measures ;
  • facilitate redressal of grievances and
  • advise the Government on all policy matters affecting women.
In keeping with its mandate, the Commission initiated various steps to improve the status of women and worked for their economic empowerment during the year under report.  The Commission received a large number of complaints and acted suo-moto in several cases to provide speedy justice.  It took up the issue of child marriage, sponsored legal awareness programmes, Parivarik Mahila Lok Adalats and reviewed laws such as Dowry Prohibition Act, 1961, PNDT Act 1994, Indian Penal Code 1860 and the National Commission for Women Act, 1990 to make them more stringent and effective.  It organized workshops / consultations, constituted expert committees on economic empowerment of women, conducted workshops / seminars for gender awareness and took up publicity campaign against female foeticide, violence against women etc. in order to generate awareness in the society against these social evils.
 
The National Commission for Women (NCW) is a statutory body of the Government of India, concerned with advising the government on all policy matters affecting women. It was established in 1992.The objective of the NCW is to represent the rights of women in India and to provide a voice for their issues and concerns. The subjects of their campaigns have included dowry, politics, religion, equal representation for women in jobs, and the exploitation of women for labour. They have also discussed police abuses against women.
 Q. 122. Critically analyse the philosophy behind the no detention policy under the Right to Education. Is the dropping of the policy the right remedy for the deteriorating learning outcomes in the schools?
Ans.
The Central Advisory Board for Education (CABE) recommended dropping no-detention policy. This controversial policy is widely being blamed for deteriorating learning levels across schools in India.

Section 16 of the RTE mandates that no child can be detained in a class until the completion of his/her elementary education. The corollary of this is continuous and comprehensive evaluation prescribed in Section 29 (h).It is aimed a progressive and holistic evaluation framework, enunciated in the National Policy on Education, 1986 and also the National Curriculum Framework, 2005. The reasons for NDP are: Examinations are often used for eliminating children who obtain poor marks. Once declared ‘fail’, children either repeat grade or leave the school altogether. Compelling a child to repeat a class is demotivating and discouraging.NDP and CCE are based on sound principles of pedagogy and assessment, recognised world-wide. They are thus a welcome change to the exam-centric culture prevalent in Indian schools. There are also very strong equity considerations behind the NDP policy, especially for children from low-income families, and girls. Failure for these children implies dropping out. Besides, research evidence indicates that detention of students by a year or more does not improve learning. Geeta Bhukkal Committee admits it.

However, after the RTE was enacted ,learning outcomes continued to dip, the NDP and CCE policies came under attack; students become lackadaisical as there is no longer a fear of failure, parents are no longer strict with their children, teachers are struggling to maintain discipline, attendance has dropped and so forth. Schools complained of poor performance in class IX because of students becoming used to automatic promotions. Geeta Bhukkal committee reported that no-detention demotivates students, and increases the burden on teachers.

However, poor learning outcomes are the product of many factors: stipulated pupil-teacher ratio (PTR) did not prevail; acute shortage of qualified teachers; Teacher training programmes must be revised in line with the requirements of CCE. These issues need to be addressed for learning outcomes and the blame should not be put at the doorstep of the NDP only.
 Q. 121. What is net neutrality? How neutral should Net be? What arguments are being advanced to regulate it? Evaluate the same.
Ans.
Net Neutrality means an Internet that enables and protects free speech and expression  It means that Internet service providers should provide us with open networks — and should not block or discriminate against any applications or content. Without Net Neutrality, cable and phone companies could carve the Internet into fast and slow lanes. An ISP could slow down its competitors' content or block political opinions it disagreed with. ISPs could charge extra fees to the few content companies that could afford to pay for preferential treatment — relegating everyone else to a slower tier of service. This would destroy the open Internet.
In India there is an opinion that the profitability of the ISPs requires them to treat some sites preferentially. They will pay the ISP but the consumers are provided free digital services to access these sites. Thus, the ISPs can raise money and built infrastructure to continue to supply quality services. It can partly break down the digital divide. The counter opinion is that such discrimination works against those sites- usually the start ups- that do t pay. They will be slowed down. Access to such applications will be chargeable. They can not come up commercially as a result. Such regulation can also have undemocratic effects.
 Q. 120. Ministry of External Affairs seeks to recruit laterally. What will be the impact? Suggest more such reforms.
Ans.
The Ministry of External Affairs has decided to take academics and private sector candidates in its Policy Planning and Research. It represents a significant movement towards a more interactive, open-minded approach on augmenting capacity and innovation within the Ministry of External Affairs. It is good that boundaries between the MEA and the world outside are made less rigid so as to permit innovative thinking in various areas, political, economic, developmental and cultural.

Over the last few years, particularly since 2010, the MEA has inducted into its offices at headquarters, deputationists from other central services of government.

A carefully calibrated expansion in the scope of lateral entry would be an appropriate strategy to infuse fresh talent into the country’s bureaucratic system.

It is suggested that some young officers should be permitted to work outside government – in corporates and nonprofits – for short periods enabling important exposure to new ideas and innovative management techniques and providing more energy, talent and dynamism in the functioning of the ministry. Even more importantly, there should be a much more active interchange of officers between the Ministries of External Affairs, Defence, Home Affairs, Finance and Commerce given the critical and interlinked nature of the areas of policy they deal with.

The MEA could also  take from state governments as the role of such governments in the execution and determination of foreign policy is becoming more substantive and important.
 Q. 119. Describe the unprecedented migrant crisis that the European countries faced. What are the political consequences of the crisis?
Ans. The European migrant crisis arose through the rising number of migrant arrivals in 2015 – a combination of economic migrants and refugees – to the European Union (EU) coming across the Mediterranean Sea and Southeast Europe from areas such as Africa, and the Middle East. Around 270,000 illegal migrants have reached Europe’s shores so far this year, more than in the whole of 2014, itself a record year.

Italy, and, in particular, its southern island of Lampedusa, receives enormous numbers of Africans and Middle-Easterns transported by traffickers operating along the ungoverned coast of the failed state of Libya.

In Poland; 70% oppose taking in asylum-seekers from Africa or the Middle East.

Slovakia wants Christian refugees only. Ban-the-burqa debates have sprung up in the three Baltic states.

As the European Union struggles with migration, northern and eastern members are becoming increasingly wary of issues regarding migration, with politicians increasingly expressing comments seen as racist. Populist parties with anti-immigrant ideology are on the rise: Sweden Democrats, a nationalist party with neo-Nazi roots, topped a poll in Sweden. Some Finnish MPs called on their countrymen to “defeat this nightmare called multiculturalism.” Those countries in the EU that resent common immigration policy may leave the Union.

Brexit is  also cited as an outcome of the fears.
 Q. 118. What is "blue economy"? How is it important for India? How is Prime Minister Narendra Modi pursuing it?
Ans.
India realizes the importance of oceans, more particularly the Indian ocean. While security in the region remains a major concern, another way to integration is cooperation in the development of a blue economy.
 
PM Modi, in his recent visit to Seychelles, Mauritius and Sri Lanka, urged for cooperation in blue economy, which is a multi-disciplinary approach for the exploitation of hydrocarbons and other marine resources; deep-sea fishing, preservation of marine ecology, mitigating climate change by addressing environmental issues and disaster management.
 
With its advancement in science and technology, India is in a position to lend expertise in deep sea bed activities, hydrographic surveys and weather predictions. India has a long record of hydrographic surveys of Seychelles and Mauritius.
 
Mauritius and Seychelles made a strong case for blue economy for their national development strategy. They want sustainable exploitation of living and non-living marine resources and deep seabed minerals to enhance food and energy security. However, these countries are constrained by a number of technological and investment and look towards India for support.
 
PM Modi, in his recent visit   signed agreements on hydrographic survey with Seychelles. He signed MoU on ocean economy with Mauritius. With  Sri Lanka, setting up of a joint task force on ocean economy was decided. During his address at the Bangbandhu Convention Centre of Dhaka University on the last day of his two-day official visit on in June to Bangladesh, PM Modi stressed the need for the two countries to work on 'Blue Economy.'
 
Indian Ocean Rim Association (IORA) and  Indian Ocean Naval Symposium (IONS) need to play active role too.
 
India, being a major littoral state in the Indian Ocean, needs to take additional initiative.
 Q. 117. What is VoLTE?
Ans.
VoLTE (Voice over LTE) is the next evolution in wireless calling. The VoLTE technology platform allows users with a compatible phone to place and receive calls over the LTE network instead of the traditional voice network. Before VoLTE, only data was transmitted over the LTE network, and voice calls were carried over the HSPA network. In May 2014, Singtel introduced the world's first commercial "full-featured" VoLTE service in Singapore. Reliance Jio announced commercial launch of 100% VoLTE service without 2G/3G based services in India on 5th Sep 2016.

Difference Between 2G, 3G, 4G, LTE and VoLTE1G, 2G, 3G and 4G are simply increasing ‘generations’ (that’s what the G stands for) of technology used in mobile devices. The first generation (1G) was analog whereas 2G began the trend for digital transmission. 3G was an evolution over 2G mostly because data bandwidth was improved and users could then enjoy faster streaming and browsing. Voice calls could’ve been potentially better too, but not like what we will now see with 4G.

The VoLTE tech provided by Jio is completely IP based, meaning even voice calls connect over data network.
 Q. 116. Preamble to the Constitution of India promises dignity of citizens. What does it mean and what has been done in this direction by the State?
Ans. Ethical and political discussions use the concept of dignity to express the idea that everyone has an innate right to be valued, respected, and to receive ethical treatment. In politics it is used in the context of the treatment of oppressed and vulnerable groups and peoples. Supreme Court held that right to life guaranteed under Art.21 of our Constitution means life with dignity. Fundamental Duties under Article 51A exhort Indian citizens “to renounce practices derogatory to the dignity of women”. Abolition of untouchability (Art.17), abolition of child labour (Art.24) are also examples of enabling dignity to the lives of the oppressed and the vulnerable. In  2011, hearing a petition on behalf of Aruna Shanbaug, the Supreme Court ruled “passive euthanasia” may be allowed in specific cases  so that some people can “die with dignity”.

Preamble to the Constitution, FRs and DPSPs assert human dignity and in its pursuit promise justice- social, political and economic.

Many Supreme Court verdicts support human dignity, the latest being making the unwed mother legal guardian of the child. The rights that were drawn from Art.21- right to life- are all meant to enhance human dignity- for example, right to elementary education.
 Q. 115. When can national emergency be imposed under the Indian Constitution? Do you think Art.352 can be invoked in the present day world?
Ans.
National emergency can be declared when there is a threat to national security due to external aggression or war or armed rebellion. It was declared thrice so far- 1962, 1971 and 1975. National Emergency can be declared again if a threat occurs to national security. It may happen from external sources or from inside the country. However, according to many, the invocation of Art.352 (National Emergency) in 1975 was avoidable. Its enforcement also left many democrats disappointed as democratic freedoms were unnecessarily suspended.
Following reasons make repetition of such miscarriage difficult:
  • Constitution has been comprehensively amended to prevent misuse of powers by the 44th Amendment Act
  • Judicial review powers have been strengthened by making it mandatory that the Union Cabinet in writing should recommend the imposition
  • President of India also may assert his power  under Art.74
  • Parliament is given special powers in terms of majority required to ratify the imposition- special majority
  • Lok Sabha may initiate its revocation
  • Civil society is strong
  • Global pressures may mount unlike last occasion when India was not globalized
  • Social media and public opinion are very effective in enforcing  responsive governance
  • Lessons have been learnt from the past experience
 Q. 114. Compare and contrast the veto of the President of India with that of his counterpart in the United States of America.
Ans. President of India is a ceremonial institution while the American President has real powers. The veto powers of the Indian President are absolute (rejection), suspensive (returning the Bill for repassage after which it is binding on the President to assent to it) and pocket veto which is not giving a decision as there is no time limit for giving the decision. There is a consensus of opinion in India that Presidential veto is exercisable only on the advice of the Council of Ministers (Art.74) as ours is a British type of Westminster system of parliamentary democracy.

After the Congress passes a bill, the President may take no action on the bill for ten days. It then becomes law. Congress must be in session for a bill to become law in this way. A bill dies after ten days if the President ignores it while Congress is not in session. It is called pocket veto. Congress cannot override a pocket veto.  Thus, it is an absolute veto.
Second, the president can issue a regular veto, sending a message to Congress that the bill is unacceptable. Congress can override a presidential veto when at least two-thirds of both the House of Representatives and Senate vote to do so. The bill becomes law after a Congressional override.
