Opinion by
Mr. Chief Justice Horace Stern,These cases were certified to this court by the Superior Court under section 10 of the Act of June 24, 1895, P. L. 212. The controlling question involved in each of them is whether a township may annex a substantial portion of the territory of another township in proceedings instituted under a statute providing merely for the alteration of the lines of two adjoining townships.
In the Allegheny County case a petition for the alteration of the lines of Indiana Township, which is a tOAvnship of the second class, and Shaler Township, which is a tOAvnship of the first class, was filed in the court of quarter sessions of the county by certain individual residents of both townships. The court appointed commissioners who held a hearing and subsequently filed a report recommending that the petition be granted and a new boundary line established as prayed for. The proceedings were based upon The Second Class Township Luav of May 1, 1933, P. L. 103, sec. 302, as amended by the Act of July 10, 1947, P. L. 1481, sec. 3. The area tó be detached from Indiana Township and annexed to Shaler Township embraced between 350 and 500 acres, being over one-half mile in width and almost a mile and a half in length; it involved some 190 separate property owners and an adult population of approximately 300 persons; the assessed valuation of its property was over $500,000.00 or about *32210% of the total assessed valuation of Indiana Township.
The court confirmed nisi the report of the commissioners, but, exceptions having been filed by the Board of Supervisors of Indiana Township and certain owners of property situate in that township, the court sustained the exceptions on the ground that such an annexation of territory was not within the purview of the statute under which the proceedings were instituted. On appeal to the Superior Court the order of the court of quarter sessions was affirmed; (171 Pa. Superior Ct. 642, 92 A. 2d 241).
In the Union County case, a petition was filed by certain inhabitants of Buffalo and East Buffalo Townships, both being second class townships, seeking an alteration in the boundary line between them. The court of quarter sessions appointed commissioners who held a hearing and subsequently filed their report recommending that the petition be granted and a new boundary line established as prayed for. The area to be detached from Buffalo Township and annexed to East Buffalo Township embraced some four square miles or, 13% of the area of Buffalo Township; it involved a population of approximately 140 persons or 10% of the total population of the township and the assessed valuation of its property was over |130,000 or about 14% of the total assessed valuation of Buffalo Township. The court confirmed the report of the commissioners., On appeal to the Superior Court the order of the court of quarter sessions was reversed; (171 Pa. Superior Ct. 653, 92 A. 2d 246).
The Second. Class Township Law of May 1, 1933, P. L. 103, sec. 302, as amended by thé Act of July 10, 1947, P. L. 1481, sec. 3, provides that “The Courts of quarter sessions may, upon the. presentation of a petition, (a) alter the lines of a [second class] township *323and any adjoining township, borough, or city so as to suit the convenience of the inhabitants thereof; (b) cause the lines or boundaries of townships to be ascertained and established; and (c) ascertain and establish disputed lines and boundaries between two or more townships or between townships and cities or boroughs.”
The First Class Township Law of June 24, 1931, P. L. 1206, sec. 302, as amended by the Act of May 27, 1949, P. L. 1955, sec. 9, contains identically the same provision in regard to first class townships.
It is, of course, obvious that every detachment of territory from one political subdivision and its annexation to another necessarily involves a change of boundary lines between the two, and, on the other hand, it is equally obvious that every alteration of the boundary lines between two political subdivisions involves a detachment of some portion of the territory of the one and its annexation to the other. What, then, are the factors marking the difference between proceedings to effect an “annexation” and proceedings to effect an “alteration of boundary lines”? They would seem to be, first, the amount of the territory involved in the change, and, second, the real objective to be accomplished. Ordinarily the desire to alter a boundary line arises because of some dispute in regard to it, or because it may be uncertain, or may happen to divide an owner’s land, or may so awkwardly meander in its course as to require straightening, the change in each of these cases involving but a comparatively negligible detachment of territory on the one side and its addition to the other side of the original boundary. Where, however, the avowed purpose to be accomplished is to detach from the one political subdivision a substantial portion of its territory and to annex it to the other, the reason for the change being based on some such *324consideration as relative school facilities, questions of taxation and assessed valuations of property, social conveniences, or the like, the proceeding becomes obviously one of annexation and the alteration in the boundary line merely incidental to the accomplishment of the larger objective.
A survey of the legislation on the subject shows that the legislature has always had in mind the difference between annexations and alterations of boundary lines, whether in the case of counties, cities, boroughs, or townships.* Some of the statutes specifically provide *325for alterations of boundary lines and others for annexations of territory, — a distinction accentuated by the *326fact that provisions for each of those purposes are sometimes included in the same act, showing plainly that it was not the legislative intention that annexations of territory should be effected in proceedings providing merely for the alteration of boundary lines. Leading to this same conclusion is the fact that in the annexation statutes there are elaborate provisions for notice to the official authorities of the political subdivisions concerned — burgess, council, commissioners or supeiwisors as the case may be — and also a requirement that assent to the annexation be given by a vote of the inhabitants of the respective townships, boroughs or cities concerned; in the case, however, of the statutes providing for the alteration of boundaries there is no mandatory provision for the giving of such notice or the obtaining of the consent of the electorate.
It may appear strange that, while there is an abundance of legislation covering annexations as between counties and boroughs, boroughs and townships, boroughs and cities, and townships and cities, and while there is a provision for the consolidation of two or more first class or two or more second class townships (Act of June 24, 1931, P. L. 1206, section 210, as amended by the act of May 27, 1949, P. L. 1955; Act of May 1, 1933, P. L. 103, section 205, as amended by the Act of July 10, 1947, P. L. 1481) there is no general provision for the annexation of one township or part thereof to another township. Whether, however, this omission is due to deliberate intent on the part of the legislature, or merely to oversight, is immaterial; in either event it is to that body that appeal must be made for the enactment of provisions permitting and governing such annexations.
Appéilants urge that the case, of The Division Line of Clay, West Cocalico and Ephrata Townships, 33 Pa. 366, is binding authority .for the proposition that sub*327stantial parts of townships may be annexed to another township under a statute providing merely for the alteration of the lines of two or more adjoining townships. The sole decision in that case, however, was that in the proceeding there instituted it was not necessary to have a concurring vote of the people affected by the change, because the Act of March 14, 1857, P. L. 93, which required such a vote, related only to proceedings to divide a township into two or more, and the Act of April 24, 1857, P. L. 304, which also required an election, related only to the erection of a new township out of two or more adjoining ones, and therefore neither of those acts was applicable. The question as to whether the annexation of the territory there involved could be effected under the Act of April 15, 1834, P. L. 537, section 13, which provided merely for the alteration of the lines of two or more adjoining townships, was not directly presented to, nor decided by, the court. In any event, this case, featured as it was by an extremely laconic opinion, and never since cited during the nearly one hundred years since it was decided, cannot be presently accepted as controlling authority.
The orders of the Superior Court are affirmed.
