Refusing to modify its order banning the sale of firecrackers in the national capital and NCR till November 1, the Supreme Court on Friday said it will ascertain after Diwali if there has been a difference in pollution levels.

Hearing a plea filed by traders with temporary licenses seeking relaxation of the ban on the sale of firecrackers, the apex court said the High Courts too must refrain from hearing similar pleas on firecrackers.

“We have made an effort to curb air pollution. We haven’t put a ban on the bursting of firecrackers and only on its sale… We will ascertain after Diwali if there has been a difference in pollution levels,” the apex court noted.

The SC also put a ban on the bursting of firecrackers after 11 pm.

The traders had moved the apex court on October 11 after its October 9 order that imposed a blanket ban on sale of firecrackers ahead of Diwali to curb pollution.

The traders told the SC that after the lifting of the November 2016 ban on September 12 this year, they had bought firecrackers for sale but the October 9 ban had caused them harm.

On Monday, the apex court has ruled that there will be no sale of firecrackers in Delhi and National Capital Region during Diwali, as it restored a November 2016 order banning the sale and stocking of firecrackers there.

However, the court had said that the September 12 order lifting the ban on the sale and stocking of firecrackers in Delhi NCR will be back into effect from November 1.
