Here's a case that hits close to home. 87 miles to the Northwest, to be exact:
National Park Service: "Non-native feral pigs are eating all the rare, native plants on Santa Cruz Island. And causing lots of other problems too. We're going to get rid of them."
Pig-Huggers: "Wait! Don't kill them! Can't you just sterilize them, or give them birth control, or something like that?"
NPS: "No. That's a hassle. Killing's easier. Faster, too."
PHs: "Okay then, I'm going to sue. You violated NEPA and CEQA."
District Court: "No they didn't."
PHs: "Here's my appeal to the Ninth Circuit."
NPS: "Go ahead. By the way, at this point, we've already killed all the pigs. They're dead, Jim. No relief. Dismiss the appeal as moot."
Ninth Circuit: "Yep. Done."
The actual opinion is a little bit longer. And not in dialogue form. But that's nonetheless pretty much what it says.
