A group called the Alliance for the Wild Rockies has filed a federal lawsuit to stop use of helicopters to herd bison back into Yellowstone park. The executive directer of the Alliance for the Wild Rockies, Michael Garrity took the time to explain to KGVO news why he believes the use of helicopters runs counter to the National Forest Managment Act, the National Environmental Policy Act, and the Administrative Procedures Act.

This same lawsuit was filed last May, and then retracted once hazing stopped. You can read the press release from a year ago here. The heart of the argument is that Grizzly Bears are being frightened out of their habitat and into foreign habitats where they end up dying. The fact that grizzlies are still on the endangered species list is what gives the lawsuit a federal edge.  If you've never seen a helicopter hazing, check out this video.
