PANAJI: Defence Minister Manohar Parrikar said that some judicial decisions amaze him and assumed that an activist in Goa had once threatened a judge to seek a favourable judgement against him, Parrikar said at the inauguration of a state of the art garbage treatment plant at Saligao plateau. When asked about ban on heavy duty diesel cars in the national capital Parrikar responded, "It implies senseless directions which do not have a scientific base. People who do not understand science have begun to interpret science. This is our misfortune," The Indian Institute of Technology-Mumbai alumnus also said that he had read a report which said that the makers of Mercedes Daimler Benz had stopped their investment of Euros 300 to 400 million in India, because the rulings in India were unusual. Parrikar further added, "Ban a diesel vehicle which is polluting, we understand it. But what is the point in banning diesel vehicle which may not pollute and may even be less polluting than a petrol vehicle”. However, the Supreme Court in December last year banned the registration of diesel vehicles with a capacity of 2000cc on account of pollution.
