Speaking to The Financial Express, additional solicitor general KN Raval said that the apex court is likely to take a decision on Wednesday whether it will take up the issue before it breaks for summer vacation or after it comes into session in July.

The court might explore the possibility of constituting a special bench to deal with the matter, said government sources. The court is to go on vacation from May 14 onwards.

In case the court decides to take up the issue after the vacation the stalemate on the registration front is expected to continue, said Government sources. Delhi government has stopped registering non-commercial vehicles soon after the apex court order.

Meanwhile, the Delhi government is expected to petitionthe Supreme Court on Wednesday to seek relaxation of the order. Legal experts gave final touches to the draft petition on Tuesday.

The document is presently being vetted by the state's chief secretary.

Apart from seeking relaxation in the cap on the number of cars that can be sold in the national capital region, the state government is likely to request the apex court to devise a method to distribute the ceiling among the four states.

"Either we go in for a single-window computerised registration system for the whole region or the court indicates a quota of vehicles to be registered by each state," said a senior state government official.

Officials added it was very difficult for the states concerned -- Delhi, Haryana, Rajasthan and Uttar Pradesh -- to mutually arrive at a quota system.

Earlier on Sunday, representatives from ministries of industry, environment, surface transport and the state government met at the office of additional solicitor general to work on the draft petition.

The stategovernment is likely to request the apex court to implement the order in other states also to prevent vehicle manufacturers from registering in other states and then bringing them to the NCR. This will entail a sizable loss of revenue for the state government.

The state government has already gone on record to say that it will loss revenue worth around Rs 10 crore each month if it were to implement the apex court order.

The date was finalised at the previous board meeting itself and was part of theregular quarterly meet to discuss accounts and budget for the year.

The board meeting is expected to be held in the a week or two, they added.

Maruti Udyog is the worst hit by the apex court directive as none of its vehicles meet the Euro-I emission norms.
