Now coming to the question, whether cutting and levelling of the area amounts to slope cutting of hill top, Learned Counsel for respondent 1 has placed reliance on National Building Code which defines Hilly Area' in view of Regulation 27 of HPTCP Rules, 2014. Applicant has not stated anywhere and could not dispute, during the course of argument, that from the definition of hill area' in National Building Code 2005, which is attracted due to Regulation 27 of HPTCP Rules, 2014, the height of Una is not above 600 meters from main sea level and therefore, it does not come within the definition of "Hilly Area". Even thereafter, if we treat that there is a small hillock and the area thereof is levelled or some slope is cut, whether it is, per se, illegal or requires any statutory permission from some authority. At least we do not come across any such provision and applicant is also not able to show any such provision during the course of the argument which would attract in the case in hand.
