A court here on Saturday acquitted social activist Medha Patkar in a criminal defamation case filed by Delhi Lieutenant Governor V K Saxena, observing that the prosecution failed to prove that she made the alleged defamatory statements during a television programme in 2006. The complaint was filed by Saxena, then president of the National Council for Civil Liberties, alleging that Patkar had defamed him during a TV programme. Judicial Magistrate First Class Raghav Sharma said the complainant failed to produce legally admissible evidence to establish that Patkar made the impugned statements.
