This chapter explores the breadth and scope of options available to states that want to indirectly protect animals across the border, in particular under the law of the World Trade Organization (WTO). The flurry of academic discussion at the intersection of animal and trade law was sparked by the Appellate Body’s Seals report in 2014, but it failed to cut deep enough to link to the doctrine of jurisdiction under general international law, and efforts to enter negotiations to more thoroughly protect animals in trade never materialized. The author advances the discussion and fills a gap in scholarship by examining whether and how states can use trade law to indirectly protect animals abroad through import prohibitions, taxes and tariffs, as well as labels. An analysis of the legality of trade-restrictive measures that indirectly protect animals under the General Agreement on Tariffs and Trade (GATT) precedes a discussion of justifications for violating the agreement.
