Acharya Balkrishna, managing director of Patanjali Ayurved and an aide of Yoga guru Ramdev, has apologised to the Supreme Court for the company's misleading claims about its products and their medicinal efficacy. The affidavit was filed yesterday, a day after the court came down heavily on Patanjali Ayurved for not responding to a contempt notice over misleading advertisements. The bench of Justice Hima Kohli and Justice Ahsanuddin Amanullah had asked Balkrishna and Ramdev to appear in court on April 2.
