President Mahinda Rajapakse should order prosecutors to drop all charges against journalists held on politically motivated charges, Human Rights Watch said in a letter to the president today. J.S. Tissainayagam, a journalist, and N. Jashiharan, a publisher, and his wife, V. Valamathy, have been in detention since March 2008. The letter identified serious violations of due process and the right to a fair trial by the authorities in Tissainayagam’s case. “Tissainayagam’s arrest was politically motivated and his detention has involved a litany of due process violations,” said Brad Adams, Asia director at Human Rights Watch.
