William R. Day,
Erie Railroad Company v. Purucker…
“ A request to charge must be calculated to give the jury an accurate understanding of the law having reference to the phase of the case to which it is applicable. Norfolk & W. R. Co. v. Earnest, 229 U.S. 115, 119, 57 L. ed. 1098, 1100, Ann. Cas. 1914C, 172, 33 Sup. Ct. Rep. 654. The first request simply asked a broad charge that if the plaintiff voluntarily, for his own convenience, went upon the tracks of the railroad, and the railroad was at the time being used and operated as a highway of interstate commerce, he assumed the risk and danger of so using the tracks. ”
