There have been court cases, and we, as well as others, learn from those court cases. And I did speak to the fact that we've had to develop a number of procedures and practices to work under the legislation. Moving from the non-statutory programs to the statutory programs has been a challenge.
Getting the staff trained in the same kinds of procedures and having the tracking in place to know where we're at has been a challenge. As I said, we're making progress on that. Some of the court cases have been around critical habitation identification, and as I pointed out, that's probably been the most scientifically challenging task for us.
