In February 2013, Kozinski wrote an opinion reversing a district court ruling that had denied Japanese whalers Institute of Cetacean Research a preliminary injunction against the US-based anti-whaling group Sea Shepherd Conservation Society. Kozinski found that the militant conservationist group were "pirates," reversed the denial of injunction by the district court, and affirmed its own provisional injunction against Sea Shepherd. The injunction bars Sea Shepherd from approaching within 500 yards of ICS vessels.
