What follows is an opinion from a United States Court of Appeals.
Your task is to identify the most frequently cited provision of the U.S. Constitution in the headnotes to this case. Answer "0" if no constitutional provisions are cited. If one or more are cited, code the article or amendment to the constitution which is mentioned in the greatest number of headnotes. In case of a tie, code the first mentioned provision of those that are tied. If it is one of the original articles of the constitution, code the number of the article preceeded by two zeros. If it is an amendment to the constitution, code the number of the amendment (zero filled to two places) preceeded by a "1". Examples: 001 = Article 1 of the original constitution, 101 = 1st Amendment, 114 = 14th Amendment.

PER CURIAM.
The plaintiff in error brought an action in the District Court to recover damages for injuries sustained by him while in the employ of the Norfolk & Western Railway Company, alleging that such injuries were caused by defendant’s negligence. To the petition of plaintiff the defendant filed an answer, denying negligence on its part, and pleading contributory negligence and assumption of risk. At the close of the plaintiff’s evidence the trial court, on motion of defendant, directed a verdict for defendant on the ground that the plaintiff was guilty of contributory negligence, which was a proximate cause of his injury.
The trial court properly sustained the motion for a directed verdict. This ease presents no new questions of law for the consideration of this court. Eor the reasons stated, it is wholly unnecessary to discuss in detail the facts or the law applicable thereto, or to express any opinion in reference to the evidence tending to prove negligence on the part of the defendant.
Judgment affirmed.
