24 Pa. Stat. § 17-1704
The affairs of joint schools or departments shall be supervised and directed (1) jointly by the several boards of school directors, establishing and maintaining such joint schools or departments, or (2) by a joint school committee, as provided in section one thousand seven hundred seven of this act. When there is no joint school committee, the several boards of school directors are hereby authorized to meet jointly, and exercise the same power and authority over the same as the several boards exercise over the schools in their respective districts. Whatever matter is required by law to be decided by a vote of the majority of all the directors of a school district shall in a joint school or department be required to be decided by a vote of two-thirds of all the constituent boards comprising said joint operation. The vote of any constituent board shall be determined by a majority vote of all the school directors comprising such constituent board. In addition thereto, the matter shall have been voted for by a majority of all the school directors of all of the constituent boards. All voting on the affairs of joint schools or departments by the school directors of the constituent boards shall be conducted either in a joint meeting or by mail ballot, whichever procedure the majority of all school directors select. The title to any real estate, acquired for the purpose of establishing any such joint school or department, shall be held in the name of one or more of the district establishing the same, as they may agree.
