In Kerala, a 12-hour hartal called by the Left Democratic Front and the BJP against diesel price hike has begun. Essential services like hospitals, newspapers, drinking water supply, important temple and church festivals have been exempted from the hartal. Universities and the State Public Service Commission have postponed examinations and interviews scheduled for today. In a related development,the State Human Rights Commission has said it would hold responsible organisations and individuals who exhorted the people to hold hartal, if they enforced it at the expense of the rights of the people, mainly right to freedom of movement and education.Chairperson of the Commission J.B.Koshy said in a statement that the Supreme Court had earlier outlawed calls for bandhs and general strikes that crippled normal life.The Commission has registered a case on its own in this regard,he said.
