The issues are (1) whether federal maritime law applies in a negligence suit against a business that organized a fishing retreat at which an invited guest allegedly became intoxicated on a boat and afterward drove a car that collided with a motorcycle and, if so, (2) whether the business owed a duty to the injured plaintiffs. In this case the Artheys sued Schlumberger, claiming Schlumberger should have supervised the invited guest, Huff, on the fishing boat on the morning just before the retreat ended. Schlumberger provided alcoholic drinks during the two-day retreat, but not on the boat. The trial court granted Schlumberger's summary-judgment motion, arguing it had no duty to the Artheys. The court of appeals reversed, holding that maritime law applied and that a fact question existed on the duty question.
