Noise pollution – use of a celebration hall – harm of neighborhood – delimitation of harm – appropriate solutions to remove harm. Country/Territory Morocco Type of court National - higher court Date Apr 8, 2014 Source UNEP, InforMEA Court name Court of Cassation Seat of court Rabat Language English Abstract Giving one of the defendants written approval to use the residence as a celebration hall is subject to not harming the neighbors because the harm is eliminated regardless of the neighbor’s acceptance to practice the activity or not, once the reasons of harm show up. Since the appealed decision is ambiguous for not specifying the harm that must be prevented and the harm that must be decreased or prevented by taking the necessary steps, the court must have assigned an expert to specify the type of harm and the appropriate solutions to prevent it.Request rejected Available in Court of Cassation’s Decisions on the environment
