The Supreme Court had some tough questions for the centre and the Indian Medical Association Tuesday as it continued a marathon hearing into the IMA's claim of misleading advertisements by Baba Ramdev's Patanjali Ayurved, including those for Coronil, a preparation touted as a "cure" for COVID-19. To begin with, Justice Hima Kohli and Justice Ahsanuddin Amanullah wanted to know why the government had omitted Rule 170 from the Drugs and Magical Remedies (Objectionable Advertisements) Act, or DMR, which prohibits ads of medicines as products with "magical" abilities.
