[Argument of Counsel from page 519 intentionally omitted]

Mr. Justice Hughes delivered the opinion of the court:


The appellant is the owner of a lot of land on the north side of Wyoming avenue, between Twentieth and Twenty-first streets, northwest, in the District of Columbia. The appellees own the adjoining lot on the west. The appellant constructed on his lot a brick dwelling, the front of which was placed 40 feet from the avenue. He located the main west wall of the dwelling about 3 feet inside of the line of his lot. This wall was about 40 feet long and three stories high. About 5 feet back of the front end of this wall the appellant projected a semihexagonal bay window, the west wall of which—about 8 feet long and extending through the height of the first story—was placed upon the line of the lot so that approximately one half the thickness of the wall was put upon the appellees' land. The appellant called this west wall of the bay window a party wall, and claimed the right to construct it in part upon his neighbors' land by virtue of the building regulations of the District of Columbia. The appellees protested against this use of their property, and brought this suit in the supreme court of the District of Columbia to enjoin the maintenance of the wall on their land. The court entered a decree in their favor, requiring its removal. The decree was affirmed by the court of appeals and this appeal is brought. 34 App. D. C. 480.


The act of June 14, 1878, chap. 194, 20 Stat. at L. 131, authorized the commissioners of the District of Columbia to make 'such building regulations for the said District as they may deem advisable,' and provided that these should have the same force within the District as if enacted by Congress. Among the regulations promulgated by the commissioners was the one approved by President Washington on October 17, 1791, relating to the location of party walls, which was recognized as in force and was 'published for the information of builders.' (Building Regulations, § 62, set forth in the margin. ) The land in question


Sec. 62. The 4th section of the building regulations, No. 1, approved by President Washington, October 17, 1791, quoted below, is recognized as in force, and is published for the information of builders. The inspector of buildings has no official duty as to the enforcement of this regulation, as the matter is one of private rights between parties:


'That the person or persons appointed by the commissioners to superintend buildings may enter upon the land of any person to set out the foundation and regulate the walls to be built between party and party, as to the breadth and thickness thereof, which foundation shall be laid equally upon the lands of the persons between whom such party walls are to be built, and shall be of the breadth and thickness determined by such person proper, and the first builder shall be reimbursed one moiety of the charge of such party wall, or so much thereof as the next builder shall have occasion to make use of before such next builder shall anyways use or break into the wall, the charge of value thereof to be set by the person or persons so appointed by the commissioners.' lies outside the original limits of the city of Washington, but the appellant contends that, by the above-mentioned act of Congress and the action of the commissioners, this regulation was made applicable throughout the District. The appellees in their bill alleged that the wall built across their line was not a party wall, that the regulation permitting the use of adjoining land for party walls did not extend beyond the bounds of the Federal city as originally laid out, and that, if it was intended to apply in the District beyond these limits, it was 'unconstitutional and void, because its effect is to deprive your complainants of their property without due process of law and just compensation.'


1. This court has jurisdiction. District Code, § 233, act of March 3, 1901, chap. 854, 31 Stat. at L. 1189, 1227; United States ex rel. Steinmetz v. Allen, 192 U. S. 543, 556, 48 L. ed. 555, 560, 24 Sup. Ct. Rep. 416; New Mexico ex rel. McLean v. Denver & R. G. R. Co. 203 U. S. 38, 47, 48, 51 L. ed. 78, 84, 85, 27 Sup. Ct. Rep. 1. As the appellees challenged the validity of the regulation if it applied to their property, as was insisted by the appellant, the case was one in which there was drawn in question the validity of an authority exercised under the United States. The question was a substantial one, and was directly presented, its determination being required unless the appellees succeeded upon one of the other issues. To justify a review of the decision under the act governing this appeal it is sufficient if the validity of the authority is drawn in question, irrespective of the conclusion reached by the court below. Baltimore & P. R. Co. v. Hopkins, 130 U. S. 210, 222, 32 L. ed. 908, 912, 9 Sup. Ct. Rep. 503. The appeal brings the entire case here. See Horner v. United States, 143 U. S. 570, 577, 36 L. ed. 266, 269, 12 Sup. Ct. Rep. 522; Penn Mut. L. Ins. Co. v. Clustin, 168 U. S. 685, 695, 42 L. ed. 626, 630, 18 Sup. Ct. Rep. 223. In this view, it is unnecessary to pass upon the conflicting contentions with respect to the amount involved.


2. Upon the merits, we need not go beyond the point on which the court of appeals rested its decision. The court held that the wall placed on the appellees' land was not a party wall. In the building regulations a party wall is defined as 'a wall built upon the dividing line between adjoining premises, for their common use.' The fundamental idea is that of mutual benefit. It is manifest that not every sort of construction projecting over the boundary, although it may form part of the exterior wall of a building, can be called a party wall. Instead of being for the common use, it may be merely an injurious protuberance. And whether or not a particular structure comes within the District rules is a question the decision of which by the court of appeals should be accepted unless there is plain error. Here we have the wall of a bay window 8 feet long projecting from the main wall of the house. Save for this short projection the main wall is set back 3 feet within the building line. The ends of the bay window wall are splayed as is usual in such cases, and while it appeared that they could be chiseled out in order to make right angles, the testimony was that if the adjoining owners desired to build in connection with the wall it would cost as much as to erect a new wall of the same dimensions. Taking the entire construction into consideration, it would seem to be merely the case of an encroachment on the adjoining property rather than that of a wall built on the dividing line, for mutual advantage. After reviewing the facts, the court of appeals summed up the matter by saying: 'It could serve no such purpose to appellees as is contemplated by the regulations of the District authorizing the construction of party walls. . . . Appellees can derive no such benefit from it as the servient owner is entitled to receive as compensation for the taking and occupation of his land. It constitutes a nuisance rather than a benefit.'


We find no reason for disturbing the decree.
