The applicant, Andrew Donald Jonathan Penwill, acting in person, sought a review of the taxation of costs ordered against him after the Constitutional Court dismissed his application for leave to appeal for lack of reasonable prospects of success in protracted litigation against his brother and other trustees of a family trust. The dispute arose from inheritance-related litigation concerning the validity of their mother’s will. After costs were taxed by the Constitutional Court’s Taxing Master, the applicant objected to several items in the bill of costs and sought to set aside a warrant of execution and notice of attachment issued against his movable property. The Taxing Master stated a case under rule 17(3) of the Supreme Court of Appeal Rules (made applicable to the Constitutional Court), and the Constitutional Court reviewed the taxation, focusing particularly on whether the correct tariffs had been applied.
