Center for Biological Diversity v. Lubchenco

After discovery, both sides moved for summary judgment. The district court granted the government’s motion, holding that the agencies’ decision was supported by the evidence and was not arbitrary or capricious.

Two environmental organizations filed suit against the National Oceanic and Atmospheric Administration Administrator, the National Marine Fisheries Service (NMFS), and the Secretary of Commerce based on their failure to list the ribbon seal as threatened because of climate change. On December 23, 2008, NMFS rejected the Center for Biological Diversity's petition to list the species, stating that although the loss of sea ice loomed as a problem for ribbon seals, it was likely that enough summer ice would remain in the seals’ habitat such that population extinction was not a risk in the foreseeable future. The lawsuit alleged that NMFS used an improperly truncated time frame of 43 years as the “foreseeable future” when determining that the ribbon seals’ sea-ice habitat was expected to continuing forming annually for the foreseeable future, failed to consider whether there might be a distinct population segment of ribbon seals that should be listed, and failed to consider whether the seals might be threatened or endangered in a significant portion of their range.
