(plaintiffs own game ranches, most of which are defined by administrative rules as "wildlife;" plaintiffs seek declaratory ruling from defendant as to whether such animals are "property of the state" as defined by statute; defendant ruled that state had no ownership or proprietary interest in plaintiffs' animals and plaintiffs' sought judicial review; applicable statute classifies plaintiffs' animals as "wildlife," but state property interest in wildlife is not proprietary or possessory that amount to ownership; state merely has regulatory authority over rather than ownership of such animals).
