Shillong, Sept 6: The Meghalaya High Court on Wednesday heard the PIL related to tree felling. During the hearing, an affidavit of the Divisiol Forest Officer (DFO), Khasi Hills (T) Division, Shillong was filed. During the course of submissions, when the High Court tried to enquire about the expertise available with the Government of Meghalaya in its Forest Department, the response from the DFO and the government advocate has, prima facie, given an impression that engagement of some experts is essential so as to regulate the entire process concerning the trees in and around the city of Shillong, which is the first issue in this petition.
