"The activity which has caused pollution is stubble burning, yesterday''s report gave a figure of 35-40% pollution in Delhi due to stubble burning. I don't know how can (SG) say that less than 10% is attributable to stubble burning. This kind of statement is actually perjury, due to this, real remedies for stubble burning not being carried out," says senior Supreme Court advocate Vikas Singh who argued for the petitioner in the Delhi pollution case in court today.
