On December 17, 2012, the National Association of Home Builders, the Olympia Master Builders, the Home Builder Association of Greater Austin, and the Texas Salamander Coalition, Inc., filed a lawsuit (pdf) against the U.S. Fish and Wildlife Service and Ken Salazar, in his official capacity, alleging that when the Service entered into stipulated settlements with WildEarth Guardians (pdf) and the Center for Biological Diversity (pdf) establishing procedures and deadlines for reviewing the listing and critical habitat determinations for 251 candidate species, it violated the Endangered Species Act and Administrative Procedure Act. A short discussion of the history leading up to these settlements can be found here. Plaintiffs allege in the complaint that "[t]he Service has abdicated a mandatory process based on best available science, public input and independent peer review in favor of a private settlement that lets two advocacy groups dictate the order, and pace of its statutorily required decision making process." As one example, plaintiffs allege that the agreements prohibit the Service from making a "warranted but precluded finding or to continue to assess information and conservation efforts that would lead to a warranted but precluded finding." While both settlement agreements do set forth procedures and deadlines for the Service's review, the agreements also state that "[t]he Agreement shall not (and shall not be construed to) limit or modify the discretion accorded to Defendants by the ESA, the Administrative Procedure Act ('APA'), or general principles of administrative law with respect to the procedures to be followed in making any determination required herein or as to the substance of any such determination. No provision of this Agreement shall be interpreted as, or constitute, a commitment or requirement that Defendants take any action in contravention of the ESA, the APA, or any other law or regulation, either substantive or procedural."
