To Free or Not to Free? State Obligations and the Rescue and Release of Marine Mammals: A Case Study of ‘Morgan the Orca’

  • Arie Trouwborst (a1), Richard Caddell (a2) and Ed Couzens (a3)

Wild animals periodically encounter difficulties or suffer injuries that require human intervention and assistance. The natural assumption is that a surviving animal will, where viable, be released back to the wild. But is there a formal legal obligation for a rescuer to do so? This question arose recently in the context of ‘Morgan’, a female killer whale rescued in poor health in Dutch waters. Morgan was successfully restored to full health, but the Dutch authorities subsequently declined to repatriate her to the wild and, controversially, transferred her to a zoological facility in Spain. This article examines the largely unexplored legal obligations incumbent upon the Netherlands in respect of rehabilitated cetaceans, in the process exposing certain problems of clarity and consistency within the present regulatory framework. By necessary implication, this article identifies emerging issues of interpretation posed by the Morgan saga, illustrating the tensions between animal welfare and nature conservation – especially in the transboundary context – and concluding firmly that the Dutch authorities erred legally in making their final decision.

5 Within the order Cetacea, the species killer whale (or orca) belongs to the suborder of the toothed whales (Odontoceti), and is the largest representative within the latter of the family Delphinidae.

186 The SeaWorld case was not the first such case in the US. In 2004 the 9th Circuit Court (which includes California in its jurisdiction) decided that ‘the world’s cetaceans’ did not have ‘standing to bring suit in their own name under the Endangered Species Act, the Marine Mammals Protection Act, the National Environment Protection Act, and the Administrative Procedure Act’: The Cetacean Community v. George W. Bush, President of the United States of America; Donald H. Rumsfeld, United States of America Secretary of Defense, US Court of Appeals for the 9th Circuit, No. 03-15866, D.C. No. CV-02-00599-DAE/BMK, filed 20 Oct. 2004; 386 F.3d 1169 (9th Cir. 2004). In this case, the cetacean community (meaning ‘all of the world’s whales, porpoises and dolphins’) challenged the US Navy’s use of certain sonar equipment which was allegedly injurious to them. This precedent may have prompted the SeaWorld plaintiffs to found their action on an alternative basis (violation of the Thirteenth Amendment).

187 Coincidentally, the orcas currently at Loro Parque originated from SeaWorld in the US.
