When Net follows Art. 14



Net Neutrality
Net neutrality can broadly be understood as the principle of non-discrimination which in practice allows the internet to be free and open by preventing service providers from slowing or interfering with the transfer of data. Net neutrality has risen as a global policy issue, yet cultural, political, commercial, and economical factors influence how net neutrality is understood and addressed in a particular context. Indeed, the factors driving the net neutrality debate, the way in which governments are addressing net neutrality, the role and response of industry, the public response, and the role of civil society has been varied across contexts. The topic of net neutrality is not limited to a technical debate and brings together a number of issues including the right to access, the right to freedom of expression, fair competition practices, and privacy.
The Debate in South Asia
The debate on network neutrality in south centers largely on the conflicting private interests of Internet Service Providers and public interest in a competitive and innovative Internet. Governments can also have an interest in regulating certain types of data packets and regulating certain services and defining the permissible interference of service providers. Discrimination of data packets can be based on different criteria - communications protocol, IP addresses, favoring private networks and enabling through different practices such as access-tiering, zero-rating, blocking and throttling of content.
Proponents of net neutrality argue that it will prevent cable and telecommunications companies from assuming the role of gatekeepers who control the flow of data and stifle innovation by providing a preference to content providers or customers who can afford to pay or those affiliated to the Internet Service Providers (ISPs). Whereas, opponents of net neutrality claim that it will allow ISPs to check for overuse of bandwidth by services such a video streaming and peer to peer file sharing, potentially leading to increased taxes, over-regulation of the Internet, and a reduction in their capacities to effectively manage their networks.
Net Neutrality across South Asia
In South Asia, due to limited connectivity to the Internet and growing digital divide, the debate on net neutrality assumes another dimension. The principle of net neutrality is seen in conflict with the initiatives like zero rating that may provide free and greater access to the Internet, albeit in a truncated form. Most South Asian jurisdictions do not have any regulations on net neutrality. India is in the process of formulating a policy around net neutrality and it has been a subject of widespread debate. On the other hand Singapore has developed a regulatory framework nationally establishing the principle of net neutrality while Bangladesh has no regulation and though civil society actors have called for regulations that govern net neutrality, no steps towards formulating regulations have been taken by the government as yet.
Virtues of net neutrality
Proponents of net neutrality include consumer advocates, online companies, human rights organizations and some technology companies. Many major Internet application companies are advocates of neutrality. Yahoo!, Vonage,eBay, Microsoft, Twitter, Amazon,Tumblr, Etsy, Daily Kos, Greenpeace, along with many other companies and organizations, have also taken a stance in support of net neutrality.
a.       Removal of gatekeepers
Supporters of net neutrality want to designate cable companies as common carriers, which would require them to allowInternet Service Providers (ISPs) free access to cable lines, the model used for dial-up Internet. They want to ensure that cable companies cannot screen, interrupt or filter Internet content without court order. Common carrier status would give the FCC the power to enforce net neutrality rules. Then cable and telecommunications companies, wanting the role of gatekeepers, being able to control which websites load quickly, load slowly, or don't load at all, will be eliminated.
b.      Equality in power
Neutral net will foster free speech and lead to further democratic participation on the internet. By ensuring that all people and websites have equal access to each other, regardless of their ability to pay, proponents of net neutrality wish to prevent the need to pay for speech and the further centralization of media power. Net neutrality protects innovation and if big companies like Google and Netflix could pay to get exceptional treatment, more bandwidth, faster speeds, the new start-up firms would be at a disadvantage.
c.       Non-discriminative
The big telecom companies can provide the ways but don’t have any right to direct how the people should walk on them. They cannot differentiate between the different groups. Net neutrality has remained a core democratizing tenet of the internet since the time it came into existence. 
d.      User intolerance for slow-loading sites
Proponents of net neutrality invoke the human psychological process of adaptation where when people get used to something better, they would not ever want to go back to something worse. In the context of the Internet, the proponents argue that a user who gets used to the "fast lane" on the Internet would find the "slow lane" intolerable in comparison, greatly disadvantaging any provider who is unable to pay for the "fast lane". 
e.       Ensures robust competition
Before taking any steps towards the regulation of OTT services however, those in charge must consider their rationale in the prevailing context, and that of the internet in the broader scheme of things: it is to connect as efficiently as possible, the users of these facilities, creating a network to enable communication and exchange of information in a manner unprecedented in history, and with enormous repercussions to the exchange and cultivation of ideas; a neutral internet supports free speech, democratic participation, and empowers citizens. By facilitating permissionfree innovation at the edges of the network, it ensures robust competition amongst service providers.
Then there is of course harnessing the benefits of the net for education, health care, and the society at large - the power of a tool with the capacity to penetrate geo-political borders as the web does, is integral to the development process.Net neutrality supports competitive marketplace and provides chance to every firm, from big companies to small start-ups to take part in it. 
f.       Reducing cost
In favour of regulation, a paper published by the Telecom Regulatory Authority of India  (TRAI) mentions that Over The Top Content (OTT Content) service providers fall under the Indian telecom licensing regime whereas Telecommunication Service Providers (TSPs) operate under a separate regime wherein voice and messaging services can be offered only after obtaining a license. TSPs have claimed that many OTT services are similar in nature to what the TSPs have been catering to, but remain unencumbered by the licensing agreements that the TSPs have to abide by while providing those services. In doing this, OTT service providers essentially piggyback over the infrastructure provided by the TSPs, which enables them to offer similar services at drastically lower costs.
As a result, there is the absence of a level playing ground for the two competing products same consumer services segment. Thus, it would be worthwhile to reorganize the services provided by OTT service providers in terms of the consumer services segment they cater to, rather than blindly classifying them as data services.

Vices Of Net Neutrality

a.      Loss of revenue
The loss of revenue caused to telecommunication companies due to the rapidly increasing use of OTT services such as popular instant messaging applications [WhatsApp, Snapchat, Google Talk], e-commerce sites [Flipkart, Amazon], video aggregation and sharing [YouTube, Vimeo, Netflix], etc., which have come to span almost the entire spectrum of the web, and all of which consume significant amounts of bandwidth without having to share their earnings with the ISPs that establish the infrastructure through which they operate. It is these services that have come under the purview of regulatory authorities in order to decide on alternative revenue-sharing models, such as those proposed by Airtel Zero.
b.      Reduction in innovation and investments
Opponents of net neutrality argue that prioritization of bandwidth is necessary for future innovation on the Internet. Telecommunications providers such as telephone and cable companies, and some technology companies that supply networking gear, argue telecom providers should have the ability to provide preferential treatment in the form of tiered services. net neutrality would make it more difficult for Internet service providers (ISPs) and other network operators to recoup their investments in broadband networks.
c.       Market alienation
Broadband connectivity in India is very low at present, and there is a huge need [and potential] for increased network creation. The next huge wave of internet users will be arriving mostly armed with low-end smart phones; it is imperative to keep in mind here that this dynamic creates a different relationship to the internet from traditional connections at home or work. In such a scenario, licensing OTT services, as the TRAI has in its consultation paper proposed to introduce, will have the obvious impact of a drop in existing users due to an increase in the prices of such services, possibly also alienating markets that have not even been tapped yet. The combination of increased costs and the monopolistic powers of ISP might make it more difficult for low-cost innovation for sustain itself, something that the internet has been especially valuable in fostering since its inception. The idea, then, of strict regulation is one which could be put in storage till such time as when India has achieved such basic goals as improved access.

d.      Hamper Growth
Theneutrality can come in the way of the growth of quality services, when elastic applications in the nature of peer-to-peer file sharing or video sharing platforms are likely to crowd out quality-sensitive services due to congestion. This does not have to have negative connotations - benefits are optimized in a network organization in which quality of service differentiation is acceptable as long as it serves a reasonable purpose and discrimination is avoided.
 In determining which behaviors are tolerable and which are not, regulators should be looking at not whether the practice is unfair, but rather at the potential harms, such as the extortion of rents, tying and bundling, etc.Users can select intelligently the mobile products and services suited to their budget; if users feel zero rated programs are discriminatory, they can simply choose not to buy them – it is not uncommon to see operators failing due to lack of consumer interest. It is obvious that telecom companies should not be allowed to engage in illegal discriminatory activity, but some commentators have pointed out that neutrality proponents are displaying a troubling pattern of wanting to eschew existing law [such as the Competition and Information Technology Acts] in favour of inventing new laws and increasing regulatory burden.
e.       Restrictive dimension
Times have changed. Today YouTube and Netflix clog the pipes with huge amounts of data. The users download insane amount of software, music and movies illegally. The changes will put a restriction. 
f.       Injustice
The various companies like Google have created services that allow people to make calls for free on networks that telecom companies have spent billions to build. Net neutrality is injustice to these companies. Some level of prioritization or restriction is essential to support the best interest of consumers as a whole. 
Given the internet’s rate of growth in India, it is not too early to develop policies that will affect a large number of people – policies and regulations which can be updated as the market expands. Any regulation which might discourage creators and users should be discouraged. OTT services form a large part of internet use generally, and act as incentives to connect to the internet. Regulations already exist for the internet at large (such as the IT Act 2000) and they should apply to mobile internet services as well.
Regulatory framework on Net Neutrality in India
The very nascent net neutrality regime in India, with no set regulations in place as yet, leaves a lot of ambiguities as to what is and isn't permissible in the transmission of data through the Internet. The (in)famous Airtel Zero plan17 has brought attention to the issue of discrimination favouring certain traffic, while the Internet.org scheme18 has brought to the fore issues of providing access to limited content, thereby blocking certain content. While both issues have been addressed by the TRAI and the DOT, even if not comprehensively, there is still a lack of clarity on the parameters within which to assess such agreements. Further, there is no deliberation on the Commission's jurisdiction to consider these issues. Moreover, Mr. M.S. Sahoo, a Member at the Commission, has recently stated that the issue of net neutrality is 'not yet on the Commission's radar', and it is 'awaiting the TRAI's decision in this regard'.19

The TRAI Paper, which invited public comments for a regime for internet regulation, has engendered high levels of skepticism20 for closely following Airtel's controversial proposal to charge higher data usage rates for the use of Voice over Internet Protocol (VoIP) services.21 The TRAI Paper has largely been perceived to favour the practice of discriminatory transmission of content by telecom companies.22 As such, the TRAI Paper has merely raised questions on the possibility of data/price discrimination by ISPs without providing clarity on the manner of regulation.
The DOT Report adopts a more concrete albeit conflated approach towards net neutrality, by calling for a 'flexible' policy involving an adoption of the 'core principles of net neutrality' while simultaneously excluding the prospect of actually defining 'net neutrality'.23 Replete with contradictions, the DOT Report entirely rejects the internet.org scheme (which is but a form of zero rating),24 while maintaining that the practice of zero-rating25 must be afforded by a case-by-case evaluation.26 The DOT Report confines its evaluation to the role of the TRAI in adjudicating the matter, without affording due consideration to the Commission as an appropriate authority to review the competitiveness of the agreements.
The entire debate overlooks the fact that the crux of the issues being debated lies in different types of agreements executed between ISPs and content providers. Indeed, it may be argued that the entire debate can be reduced simply to the impact of these agreements on the markets in which the parties operate, and on the customers of the services offered by them. The Commission is likely to have a more nuanced perspective to this debate, through a comprehensive consideration of the market effects. Moreover, it appears to overlook the necessity of tailoring the net neutrality regime to suit the needs of the Indian market, such as the pressing urgency to improve internet penetration in India.27
An assessment accounting for these factors may lead to the conclusion that the internet need not necessarily be strictly 'neutral'. In India, the Commission is well-equipped to conduct this assessment in a wholesome manner.28 The Commission has the powers to effectively rule on the competitiveness of non neutral platforms such as internet.org and Airtel Zero on the basis of their actual and/or likely effects on the Indian market and consumers. Arguably, zero-rating platforms such as internet.org, though ex facie rejected by DOT Report, may be found to have some efficiencies and benefits in India upon an assessment of the operation of the vertical agreement. This evaluation would, however, call for the Commission to exercise its jurisdiction over the matter.
While TRAI’s paper has received criticism, it should be noted that the paper does devote a significant proportion to discussing Net Neutrality and the negative impact it could have if India overlooks the principle. The paper says, “A policy decision to outright depart from “NN” (Net Neutrality) raises various antitrust and public interest issues. There are concerns that TSPs will discriminate against certain types of content and political opinions. Such practices may hurt consumers and diminish innovation in complementary sectors such as computer applications and content dissemination. Discriminatory pricing proposals, if implemented, could raise a variety of significant anti-competitive concerns.” Discriminatory pricing proposals are what activists fear could take place if India abandons its stand on Net Neutrality, and users will be the one to suffer.
What concerns does Net Neutrality raise? What harms does it entail?
Discriminatory practices at the level of access to the Internet raises the following set of concerns:
1. Freedom of speech and expression, freedom of association, freedom of assembly, and privacy.
2. Harm to effective competition
a. This includes competition amongst ISPs as well as competition amongst content providers.
b. Under-regulation here may cause harm to innovation at the content provider level, including through erecting barriers to entry.
c. Over-regulation here may cause harm to innovation in terms of ISP business models.
3. Harm to consumers
a. Under-regulation here may harm consumer choice and the right to freedom of speech, expression, and communication.
b. Over-regulation on this ground may cause harm to innovation at the level of networking technologies and be detrimental to consumers in the long run.
4. Harm to "openness" and interconnectedness of the Internet, including diversity (of access, of content, etc.)
a. Exceptions for specialized services should be limited to preserve the open and interconnectedness of the Internet and of the World Wide Web.
It might help to think about Net Neutrality as primarily being about two overlapping sets of regulatory issues: preferential treatment of particular Internet-based services (in essence: content- or source-/destination-based discrimination, i.e., discrimination on basis of 'whose traffic it is'), or discriminatory treatment of applications or protocols (which would include examples like throttling of BitTorrent traffic, high overage fees upon breaching Internet data caps on mobile phones, etc., i.e., discrimination on the basis of 'what kind of traffic it is').
Situations where the negative or positive discrimination happens on the basis of particular content or address should be regulated through the use of competition principles, while negative or positive discrimination at the level of specific class of content, protocols, associated ports, and other such sender-/receiver-agnostic features, should be regulated through regulation of network management techniques . The former deals with instances where the question of "in whose favour is there discrimination" may be asked, while the latter deals with the question "in favour of what is there discrimination".
In order to do this, a regulator like TRAI can use both hard regulation - price ceilings, data cap floors, transparency mandates, preventing specific anti-competitive practices, etc. - as well as soft regulation - incentives and disincentives.
3.1.1 Net Neutrality and human rights
Any discussion on the need for net neutrality impugns the human rights of a number of different stakeholders. Users, subscribers, telecom operators and ISPs all possess distinct and overlapping rights that are to be weighed against each other before the scope, nature and form of regulatory intervention are finalised. The freedom of speech, right to privacy and right to carry on trade raise some of the most pertinent questions in this regard.
For example, to properly consider issues surrounding the practice of paid content-specific zero-rating from a human rights point of view, one must seek to balance the rights of content providers to widely disseminate their 'speech' to the largest audiences against the rights of consumers to have access to a diverse variety of different, conflicting and contrasting ideas.
This commitment to a veritable marketplace or free-market of ideas has formed the touchstone of freedom of speech law in jurisdictions across the world as well as finding mention in pronouncements of the Indian Supreme Court. Particular reference is to be made to the dissent of Mathew, J. in Bennett Coleman v. Union of India[7] and of the majority Sakal Papers v. Union of India[8] which rejected the approach.
Further, the practice of deep-packet inspection, which is sometimes used in the process of network management, raises privacy concerns as it seeks to go beyond what is "public" information in the header of an IP packet, necessary for routing, to analyzing non-public information. [9]
3.2 What conditions and factors may change these concerns and the regulatory model we should adopt?
While the principles relating to Net Neutrality remain the same in all countries (i.e., trying to prevent gatekeepers from unjustly exploiting their position), the severity of the problem varies depending on competition in the market, on the technologies, and on many other factors. One way to measure fair or stable allocation of the surplus created by a network - or a network-of-networks like the Internet - is by treating it as a convex cooperation game and thereupon calculating that game's Shapley value:[10] in the case of the Internet, this would be a game involving content ISPs, transit ISPs, and eyeball (i.e., last-mile) ISPs. The Shapley value changes depending on the number of competitors there are in the market: thus, the fair/stable allocation when there's vibrant competition in the market is different from the fair/stable allocation in a market without such competition. That goes to show that a desirable approach when an ISP tries to unjustly enrich itself by charging other network-participants may well be to increase competition, rather than directly regulating the last-mile ISP. Further, it shows that in a market with vibrant last-mile competition, the capacity of the last-mile ISP to unjustly are far diminished.
In countries which are remote and have little international bandwidth, the need to conserve that bandwidth is high. ISPs can regulate that by either increasing prices of Internet connections for all, or by imposing usage restrictions (such as throttling) on either heavy users or bandwidth-hogging protocols. If the amount of international bandwidth is higher, the need and desire on part of ISPs to indulge in such usage restrictions decreases. Thus, the need to regulate is far higher in the latter case, than in the former case.
The above paragraphs show that both the need for regulation and also the form that the regulation should take depend on a variety of conditions that aren't immediately apparent.
Thus, the framework that the regulator sets out to tackle issues relating to Net Neutrality are most important, whereas the specific rules may need to change depending on changes in conditions. These conditions include:
● last-mile market
○ switching costs between equivalent service providers
○ availability of an open-access last-mile
○ availability of a "public option" neutral ISP
○ increase or decrease in the competition, both in wired and mobile ISPs.
● interconnection market
○ availability of well-functioning peering exchanges
○ availability of low-cost transit
● technology and available bandwidth
○ spectrum efficiency
○ total amount of international bandwidth and local network bandwidth
● conflicting interests of ISPs
○ do the ISPs have other business interests other than providing Internet connectivity? (telephony, entertainment, etc.)
 Conclusion
The Internet exists as a network acting as an intermediary between providers of content and it users. Traditionally, the network did not distinguish between those who provided content and those who were recipients of this service, in fact often, the users also function as content providers. The architectural design of the Internet mandated that all content be broken down into data packets which were transmitted through nodes in the network transparently from the source machine to the destination machine. The idea was for the protocol layer to be as simple and feature free as possible such that it is only concerned with the transmission data as fast as possible (‘best efforts principle’) while innovations are pushed to the layers above or below it. This aspect of the Internet’s architectural design which mandates that network features are implemented at the end points only (destination and source machine), i.e. at the application level, is called the ‘end to end principle’. This means that the intermediate nodes do not differentiate between the data packets in any way based on source, application or any other feature and are only concerned with transmitting data as fast as possible, thus creating what has been described as a ‘dumb’ or neutral network. There needs to exist further policy making to ensure and maintain the efficiency of such policy.
To begin with, the government might be well-advised to keep indigenously produced or India-specific apps unregulated and unlicensed for the time being. As stated above, the Indian market is one that is as yet to achieve anywhere close to its full potential, and if OTT service providers are made to share revenue as envisaged by TRAI, or otherwise be circumscribed in any form, this will discourage entry-level players who are right now are free to experiment in the web domain and might not possess the wherewithal needed to navigate bureaucratic procedure.
Refraining from licensing OTT apps will help Indian creators as much as anyone else. Following the principles of net neutrality and eliminating zero-rating would also ensure that there is fair competition in the Indian app market. Other incentives could also be offered to app-makers under the ‘Make in India’ scheme.
There is no need for any additional licensing. Indian laws still apply to apps, for example, companies conducting business including e-commerce. From the telecom perspective, there is no reason to classify these services in any way other than to acknowledge that they are part of the internet, and price them accordingly based on usage.
-  There should be a focus on freeing up spectrum space which is currently lying unused
-  If market studies suggest that it is viable, TSPs should be encouraged to switch entirely to packet-switched networks
-  If it is considered that having some internet - in the form of zero-rated platforms or ‘walled gardens’ - is better than having no internet at all, which is the case for many in India, steps should be taken to ensure that the market is eventually balanced. Acknowledging that zero-rating violates net neutrality, a grace period could be set during which service providers could team up with certain OTT providers to give customers free internet access, with the knowledge that such an arrangement would be time-barred.

Raod Rationing Plan. Delhi's New year resolution

well 1st Jan, 2016, New Delhi begins with it's transient review resolution of  pollution maintenance.
The implementation of such a resolution is a gamble as people anywhere in the world are resistant to change and with advancement they are more attached to comfort.
here are some pointers and a review on the ROAD RATIONING SYSTEM to be implemented.

Outlining the contours of its ambitious plan to curb pollution through odd-even number plate formula, Delhi government on Sunday said odd-numbered vehicles will be allowed to ply on Monday, Wednesday and Friday while even-numbered vehicles will run on the other days - Tuesday, Thursday and Saturday.
It is definitely an unconventional step by the Delhi government and it may be inconvenient to us in some ways. These kind of policies are implemented in developed cities around the world for a short period of time, till the pollution levels come down. this was run down in by Hindustan times.

The Strengths
1.      The pollution of delhi has risen to an alarming level, and this policy implemented in majoy cities of other countries have worked out well to reduce pollution level. Why can’t delhi do the same. According to the World Health Organization, New Delhi had in 2014 the most polluted air of about 1,600 cities the organization tracked around the world. 

2.      It is only for a temporary basis. Oonce the pollution level is under control, the restricition will  be lifted
3.      Emergency vehicles-The minister said that the government will only allow emergency vehicles like PCR Van, Fire tenders, ambulance to run on roads in the national capital.
4.      It will also help improve the public transportation and full exploitation of such facilities
5.      Car Pooling- it makes scope for government’s old plan of no 1 man car driving.
6.      It is a system to control traffic and pollution, giving scope for faster travel and is also cost effective as people will resort to methods like car pooling, electric vehicles or cycles, etc.
7.      To take measures the city has also planned to shut down the badarpur thermal power plant due to it being out dated and inefficient. It has also proposed to take measures against generators operated by companies and factories.Chief Secretary K K Sharma 
8.      The minister has also sought people's suggestions on the government's odd-even formula. People can send their suggestions to mailto:pollutionfreedelhi@gmail.com, he said. Shows that government is ready to take into consideration the various flaws and is not making an arbitrary policy.

Beijing Model
·         On August 20th, for next 15 days, Beijing put restrictions on factory production and car use. Five million cars were forced to drive on alternating days.
·         Officials cleaned up Beijing’s air in advance of the parade by suspending or restricting the operations of 12,255 coal-burning boilers, factories and cement-mixing stations scattered among seven provinces. About 5,700 of the enterprises were in Beijing and in Hebei province, which surrounds the city.
·         90% of the Beijing residents didn’t find the restriction inconvenient as it would make their lives better
·         *Rationing was done for two months. Implementation was through automated traffic surveillance
·         *Car owners were compensated by exemptions from paying vehicle taxes for three months.
·         During the ban, Beijing’s average levels of PM (particulate matter) dropped by 73.2% compared to the last year.
·         40,000 construction sites in and around Beijing were also shut down for the duration


The Weakness                                                                                             
The problem with implementing Road Space Rationing in Delhi is the lack of public transport infrastructure. The Metro still covers only 12% of the area of the city within walking distance.  The buses are a disaster to travel in terms of comfort, frequency, safety or efficiency for the upper middle class.  There are no cycling lanes, if one had to move to more friendly sources of transport.  The central government has done nothing to encourage the use of electric vehicles or hybrids in the last 10 years. In fact their policies have discouraged car manufacturers from producing hybrids.  Car companies have therefore considered eco friendly cars a losing proposition.  If anything the price value equation for electrics and hybrids makes them luxury cars, preventing the average Indian from experimenting with them.
·         The number 0-
Zero is an even number; indeed, half of the numbers in a given range end in 0, 2, 4, 6, 8 and the other half in 1, 3, 5, 7, 9, so it makes sense to include 0 with the other even digits for rationing. However, many people are unaware that zero is even, and this ignorance can cause confusion. The relevant legislation sometimes stipulates that zero is even.
[8] In fact, an odd–even restriction on driving in 1977 Paris did lead to confusion when the rules were unclear. On an odd-only day, the police avoided fining drivers whose plates ended in 0, because they did not know whether 0 was even.
·         Control of Police
Beijing resorts to road rationing with its ruthlessly efficient police force’s writ running. Here in Delhi, however, the Kejriwal government is constantly at loggerheads with the Centre. Delhi Police, including those manning traffic, come under the Central control which for all one knows might not do Kejriwal’s bidding if only to spite him. The traffic police in many of the Latin American countries employ overhead cameras to capture smartly the number plates of cars that had no business to be on roads at a given point of time pursuant to the road rationing policy
·         Private services
Taxi drivers and auto rickshaws drivers will be the worst hit. In a way it affects the livelihood of people who are depended on private transportation.
·         Reluctance to use Public Transport
Most of the car owners are well heeled and reluctant to use public transport.
·         Corrupt alternatives
Many of them would go for a second car with a number plate that allows them to use both the cars on alternate days without falling foul of the law. And the intrepid ones would take the risk of falling foul of the law by tampering with the last digit, smug in the belief if caught they would bribe their way through.
·         Inconvenience to tourists
people from out station passing via delhi will be forced and restricted. Since the plan is leveled on equity basis, such people will be affected.
·         Doesn’t plan contingency
This policy does not take cause of an event happing like heart attack or any medical condition, floods, incessant rainfall,  food supplying trucks. This policy will hit majority of the market as well as the priority sector as transportation will be hit, storage increase, wastage increases, as well as the medical health and works totally against the public welfare scheme
·         Under-developed Infrastructure
Apart from the sheer impossibility of enforcement unless equipped with smart devices, there would untold and countless inconveniences galore. Employees would not be able to make it on time to offices in the absence of an effective public transport system on routes not covered by the Delhi metro. Patients may have to call ambulance if they fall sick on the day that is not theirs on the roads. Families would sulk if they are unable to make it to parties and functions taking place unfortunately again on days not theirs on the Delhi roads.

Alternative methods
·         Kejriwal might even rethink his proposal in a limited way -- allow HOVs or high occupancy vehicles. In Washington, for example, a car with two occupants makes the grade for this description and is allowed to enter the left most lane so it can zip past. Kejriwal can mandate four instead. Low Emission Zone, Car Free days, Congestion pricing, and Traffic Calming are other ways in which to reduce air pollution. 
o    Low Emission Zone : An area is defined for low emission with the aim of improving air quality in that particular area typically one that has much higher pollution levels.  
o    Car Free days : Where Motorists are encouraged to give up their cars for a day.  Mumbai is already experimenting with a  variation of this on Linking Road on Sundays for a few hours.  It is likely to happen in other areas as well.
o    Congestion Pricing : Where users are charged a premium to enter certain high traffic areas. For example in some cities in the world there is an extra price to pay to enter the CBD area of the city.
o    Traffic Calming : Speed bumps and other measures like narrowed roads to slow down the traffic. Unfortunately in India narrow roads and bumps to slow down cars have been in existence for other reasons for many years.
·         Singapore, for instance, uses a system of auctioned permits and electronic road pricing. Thus, the restriction is based on price rather than on rationing. Cars are charged as they drive around the city and the pricing varies on location and time of day. Such a system will require some upfront investment in technology but the outcome will be vastly better and give car users a lot more flexibility. Perhaps Delhi could even leapfrog into a more advanced GPS (global positioning system)-based system.
According to the Ministry of Urban Development Study the modal share of transport in Delhi are in the above graph.  Mass transit constitutes 42% of all journeys.  So really speaking putting the clamps down on private vehicular traffic may not save Delhi from its unacceptable levels of particulate matter. It at best can reduce private traffic from 19% to 9.5%.

Flaws in the system model
Mexico City residents began to buy extra cars with convenient number plates. In fact, they slowed down the purchase of new cars and began to buy old, inefficient cars from the rest of the country. This actually made things worse. Moreover, the shift in the mode of transportation was from cars to taxis rather than to metro trains. Thus, the taxis made more money but air quality did not improve. After two months of implementation, petrol sales went up. Based on these findings, a technical study commissioned by New York City argued against introducing such a system in 2007.
Further, the long-term outcomes were not so encouraging. A study of air quality impact published in 2007 by Lucas Davis of the University of Michigan concluded: “Across pollutants and specifications there is no evidence that the program has improved air quality. The policy has caused a relative increase in air pollution during weekends and weekday hours when the restrictions are not in place, but there is no evidence of an absolute improvement in air quality during any period of the week for any pollutant.”

Petrol vs diesel pollution- http://www.air-quality.org.uk/26.php

Emissions from Petrol Vehicles
Emissions from petrol cars have been dramatically reduced by the introduction of catalytic converters, which oxidise pollutants such as CO to less harmful gases such as CO2. When compared to petrol cars without catalysts, catalyst cars have much lower CO, HC and NOx emissions, at the expense of CO2 emissions, which increase due to the oxidation of carbon monoxide to CO2. As a consequence of this, a catalyst car will also use slightly more fuel and become less efficient. However, despite these improvements, petrol cars with catalysts still produce more CO and HC than diesel cars, although exhaust emissions of NOx and particulates are much lower than diesel cars. In fact particulate emissions from petrol cars are so low that they are not routinely measured.

Emissions from Diesel Vehicles
Diesel fuel contains more energy per litre than petrol and coupled with the fact that diesel engines are more efficient than petrol engines, diesel cars are more efficient to run. Diesel fuel contains no lead and emissions of the regulated pollutants (carbon monoxide, hydrocarbons and nitrogen oxides) are lower than those from petrol cars without a catalyst. However, when compared to petrol cars with a catalyst, diesels have higher emissions of NOx and much higher emissions of particulate matter.

in the following view it's an over-ambitious plan on behalf of Kejriwal. a lot of questions have been raised this plan. New action plans have been incorporated like doctors will be allowed to travel, 0 will be an even number, emergency patients will be given a pass, outside tourists will be within the ambit of the embargo, etc. how far will this plan be successful....well only time will tell. 
notwithstanding anything AAP govt. is determined to implement this review plan.
