Watson brought a negligence case against the PrescripShun Drug Store to recover damages for injuries he received from falling on the wet floor of the store. He believed that the store was negligent for marking the floor with only a small sign that said "Slippery When Wet." The trial court refused to let Watson introduce evidence that after his fall the store started marking wet floors with cones and a large sign saying, "Caution-Floor Is Wet and Slippery."
Watson lost in the trial court and lost his appeals to the state appeals court and state supreme court. Will he be able to appeal to the U.S. Supreme Court? Why or why not?
