Supreme Court allows unfair pricing and unfair contract terms by dominant energy supplier against housing cooperative.

The Supreme Court of Poland quashed the lower court's decision and remanded the case for a new ruling on costs. The Court found that the energy company's uniform pricing for heat, despite differing infrastructure costs, constituted unfair pricing under the Competition and Consumers Protection Act. Furthermore, the unilateral termination of a cost-refund agreement was deemed an unfair contract term imposed on the cooperative. The Court rejected the argument that natural monopolies are exempt from these prohibitions, establishing that cross-subsidization and unilateral contract changes violate competition law.
