[JURIST] The Pacific Legal Foundation has initiated a challenge to plans by the government to designate four dozen endangered species for protection under the Endangered Species Act. The foundation notified the US Fish and Wildlife Service and the National Marine Fisheries Service Monday of its plans to challenge the agencies' action. The foundation claims that the government underestimated the economic impact of preserving habitat for the species based on a district court decision [PDF] in California. The Endangered Species Act requires advance notice before a lawsuit is filed. Read Pacific Legal's 60-day notice [PDF] of its intent to sue and a press release. AP has more.
