In Practice. A statement of all the facts of a case, with the names of the witnesses, and a detail of the documents which are to support them. A brief. A case stated is a substitute for a verdict, resorted to for convenience and to save the expense of a trial, its purpose being not to make evidence for a jury, but to supersede the action of a jury altogether, by imparting to facts ascertained by consent the judicial certainty requisite to enable the court to pass upon the law, and give judgment on the whole; and its existence is consequently inconsistent with an issue to draw the facts again into contest. 5 Am. & Eng. Ency. 2nd ed., 750-1; 4 Watts (Pa.) 312. A substitute for a special verdict, adopted for convenience to save the labor and ex- pense of finding the same facts by the jury in the form of a special verdict. Id.; 8 W. & S. (Pa.) 41. Sce AGREED CASE. An agreement in writing, between a plaintiff and defendant, that the facts in dispute between them are as therein agreed upon and set forth. 3 Whart. 143. Some process of this kind exists, it is presumed, in all the states, for the purpose of enabling par- ties who agree upon the facts to dispense with a formal trial to ascertain what is already known, and secure a decision upon the law involved merely. These agreements are called also agreed cases, cases agreed on, agreed statements, etc. In chan- cery, also, when a question of mere law comes up, it is referred to the king's bench, or common pleas, upon a case stated for the purpose; 8 Sharaw. Bla. Com. 458, n.; 6 Term 318. The case stated usually embodies a writ- ten statement of the facts in the case con- sented to by both parties as correct, and submitted to the court by their agreement, that a decision may be rendered upon the court's conclusions of law on the facts stated, without a trial by jury. The facts being thus ascertained, it is left for the court to decide for which party is the law. As no writ of error lies on a judgment rendered on a case stated; Dane, Abr. c. 187, art. 4, § 7; it is usual in the agreement to insert a clause that the case stated shall be considered in the nature of special verdict. In that case, a writ of error lies on the judgment which may be rendered upon it. But a writ of error will also lie on a judgment on a case stated, when the parties have agreed to it; 8 S. & R. 529; and it is usual to include such a provision. There must be a pending action, in which the case is stated; 4 D. R. (Pa.) 490.; it must state all the facts; and cannot refer to outside documents; 132 Pa. 545; the court must decide on the case stated, not on the report of a master subsequently appointed; 182 Pa. 578; and cannot go outside of the case stated in deciding it; 148 Pa. 282; id. 441; 149 Pa. 302; if no right of appeal is re- served, the decision of the court is final; 153 id. 625. Where a controversy is submitted to a court upon a case stated, but which fails to recite that it is submitted for its opinion on the law and judgment, the court is with- out jurisdiction to render judgment; 77 Md. 412. Where an agreed statement was made by the parties under a mistake of facts, it was a proper subject of amend- ment; 3 Wash. St. 420.
