5. A bird is a rare species of quail found only in the state. Because its flesh is tasty, it was hunted nearly to extinction until 30 years ago. At that time, the state instituted conservation and game management programs designed to preserve the bird. These programs included the establishment of breeding preserves, the employment of ornithologists to study the bird's habits, the passage of laws restricting the hunting of the birds, and the employment of game wardens to enforce those laws. The expense of maintaining the programs was financed in part by the sale of hunting licenses. A recent statute passed by the state legislature fixes the fee for a hunting license at $10 per year for state residents, and $20 per year for nonresidents. A hunter who resides outside the state was arrested in the state and prosecuted for hunting without a license in violation of the statute. He defended by asserting that the statute is unconstitutional because the hunting license fee for nonresidents is higher than for residents.
