Lewis signed a contract for the rights to all timber located on Nine-Mile Mine. He agreed to pay $70 per thousand board feet ($70/mbf). As he began work, Nine-Mile became convinced that Lewis lacked sufficient equipment to do the job well and forbade him to enter the land. Lewis sued. Nine-Mile moved for summary judgment. The mine offered proof that the market value of the timber was exactly $70/mbf, and Lewis had no evidence to contradict Nine-Mile. The evidence about market value proved decisive. Why? Please rule on the summary judgment motion.
