Green Tribunal courts to address the environmental issues will start functioning soon across the country. Replying supplementaries in the Rajya Sabha today, Environment minister Jairam Ramesh said under the National Green Tribunal Act, process of appointment of five judicial and seven expert members will be completed in the near future. Sharing the concerns of the members, the minister said that environment ministry is keen that the credibility of the tribunals is established from day one and that is why the selection committee is headed by a retired Supreme Court judge. The minister said any citizen can file an appeal in the Tribunal against an order granting environmental clearance. He, however, informed the members that right to appeal to the High Court is a constitutional right which can not be withdrawn.
