§ 17. Legislative Reapportionment Commission. (a) In each year following the year of the Federal decennial census, a Legislative Reapportionment Commission shall be constituted for the purpose of reapportioning the Commonwealth. The commission shall act by a majority of its entire membership. (b) The commission shall consist of five members: four of whom shall be the majority and minority leaders of both the Senate and the House of Representatives, or deputies appointed by each of them, and a chairman selected as hereinafter provided. No later than 60 days following the official reporting of the Federal decennial census as required by Federal law, the four members shall be certified by the President pro tempore of the Senate and the Speaker of the House of Representatives to the elections officer of the Commonwealth who under law shall have supervision over elections. The four members within 45 days after their certification shall select the fifth member, who shall serve as chairman of the commission, and shall immediately certify his name to such elections officer. The chairman shall be a citizen of the Commonwealth other than a local, State or Federal official holding an office to which compensation is attached. If the four members fail to select the fifth member within the time prescribed, a majority of the entire membership of the Supreme Court within 30 days thereafter shall appoint the chairman as aforesaid and certify his appointment to such elections officer. Any vacancy in the commission shall be filled within 15 days in the same manner in which such position was originally filled. (c) No later than 90 days after either the commission has been duly certified or the population data for the Commonwealth as determined by the Federal decennial census are available, whichever is later in time, the commission shall file a preliminary reapportionment plan with such elections officer. The commission shall have 30 days after filing the preliminary plan to make corrections in the plan. Any person aggrieved by the preliminary plan shall have the same 30-day period to file exceptions with the commission in which case the commission shall have 30 days after the date the exceptions were filed to prepare and file with such elections officer a revised reapportionment plan. If no exceptions are filed within 30 days, or if filed and acted upon, the commissions's plan shall be final and have the force of law. (d) Any aggrieved person may file an appeal from the final plan directly to the Supreme Court within 30 days after the filing thereof. If the appellant establishes that the final plan is contrary to law, the Supreme Court shall issue an order remanding the plan to the commission and directing the commission to reapportion the Commonwealth in a manner not inconsistent with such order. (e) When the Supreme Court has finally decided an appeal or when the last day for filing an appeal has passed with no appeal taken, the reapportionment plan shall have the force of law and the districts therein provided shall be used thereafter in elections to the General Assembly until the next reapportionment as required under this section 17. (f) Any district which does not include the residence from which a member of the Senate was elected whether or not scheduled for election at the next general election shall elect a Senator at such election. (g) The General Assembly shall appropriate sufficient funds for the compensation and expenses of members and staff appointed by the commission, and other necessary expenses. The members of the commission shall be entitled to such compensation for their services as the General Assembly from time to time shall determine, but no part thereof shall be paid until a preliminary plan is filed. If a preliminary plan is filed but the commission fails to file a revised or final plan within the time prescribed, the commission members shall forfeit all right to compensation not paid. (h) If a preliminary, revised or final reapportionment plan is not filed by the commission within the time prescribed by this section, unless the time be extended by the Supreme Court for cause shown, the Supreme Court shall immediately proceed on its own motion to reapportion the Commonwealth. (i) Any reapportionment plan filed by the commission, or ordered or prepared by the Supreme Court upon the failure of the commission to act, shall be published by the elections officer once in at least one newspaper of general circulation in each senatorial and representative district. The publication shall contain a map of the Commonwealth showing the complete reapportionment of the General Assembly by districts, and a map showing the reapportionment districts in the area normally served by the newspaper in which the publication is made. The publication shall also state the population of the senatorial and representative districts having the smallest and largest population and the percentage variation of such districts from the average population for senatorial and representative districts.
