A property owner who conducts earthworks, dam construction, or other alterations on a neighbouring property without permission acts wrongfully and unlawfully, and is obligated to restore the status quo ante. Where such unauthorized construction causes environmental damage including vegetation removal and alteration of natural ground contours, the wrongdoer must rehabilitate the affected area under supervision of environmental experts, at the wrongdoer's cost. This includes removing unauthorized structures, restoring natural ground contours, and replanting with appropriate indigenous vegetation. A landowner cannot restrict a neighbour's established right of access (via necessitas) to their property. Costs may be awarded on an attorney-client scale where a party's conduct has been particularly egregious and the party has ignored repeated correspondence seeking to resolve the dispute.
