Nominal damages are a trifling sum awarded to a plaintiff in an action, where there is no substantial loss or injury to be compensated, but still the law recognizes a technical invasion of his rights or a breach of the defendant’s duty, or in cases where, although there has been a real injury, the plaintiff’s evidence entirely fails to show its amount. Maher v. Wilson, 139 Cal. 514, 73 Pac. 418; Stanton v. Railroad Co., 59 Conn. 272, 22 Atl. 300. 21 Am. St. Rep. 110; Springer v. Fuel Co., 196 Pa. 156. 40 Atl. 370; Telegraph Co. v. Lawson, 60 Kan. 000, 72 Pac. 2S3; Railroad Co. v. Watson, 37 Kan. 773. 15 Pac. 877. Substantial damages are considerable in amount, and intended as a real compensation for a real injury.
