On 28 December 2011, the Court of Appeal of The Hague rendered a judgment in the dispute between the Municipality of Rotterdam and Eneco over the question of who should bear the costs of moving certain pipes (the instruction to move the pipes was given by the Municipality). The court ruled that by virtue of the transfer of the Municipality's energy-related activities to Eneco's legal predecessor in 1992, Eneco acquired a right of superficies (opstalrecht) in respect of the pipes and that this right consists not only of ownership of the pipes, but also of a right to have the pipes situated in the relevant location (a right in rem referred to in the judgment as a "ligrecht"). The court issued a declaratory judgment stating (inter alia) that the parties had agreed that the costs of moving cables and pipes would be borne entirely by the party that had caused the relevant object(s) to be moved.
