April 1, 2003 Final Rule to Reclassify/Delist the Gray Wolf

This "Final Rule " is not in effect

On January 31, 2005, a U.S. District Court in Portland, Oregon vacated and enjoined the Final Rule and the Department of Justice declined to appeal the decision. The Vermont District Court ruled similarly. Therefore, the Service considered that the gray wolf reverted back to the ESA status that existed prior to the 2003 reclassification (i.e., Threatened in Minnesota and Endangered in remainder of conterminous U.S.).
