53 Pa. Stat. § 13109
The new charter proposed by the commission or the proposed amendments which the city council of the city shall have provided, by ordinance, for submission to the qualified electors of the city for their approval or disapproval, as provided in section six of this act, shall be filed with the city council, which shall thereupon cause said proposal or proposals, together with the form of the question or questions hereinafter provided for, to be printed in pamphlet form in sufficient number for general distribution. The said pamphlets shall be made ready for distribution at least twenty-eight days before the election at which the proposals aforesaid are to be voted upon by the electors and the said proposals, together with the said ballot questions, shall also be published not less than once or more than three times, as city council shall determine, in three newspapers of general circulation in the city. Such publications shall appear during the three weeks immediately preceding the election at which the vote is to be taken upon said proposals. Each ballot question shall be framed in brief form of not more than seventy-five words by the commission proposing the new charter, or by the city council of the city, in the case of amendments. The said questions shall be stated in the report of the commission or in the ordinance of the city council. Whenever a proposed new charter or amendments shall propose any change in the manner of selection of elected city officers, such proposal and the necessary ballot question shall be stated separately from the remainder of the proposed new charter in the report or ordinance, as the case may be, and in the publications herein required. The commission may require that its proposed charter be submitted in two or more parts, so arranged that corresponding parts of the existing charter shall remain in effect if one or more of such parts are not adopted, and may also submit alternative charters or alternative provisions to supersede designated portions of the proposed charter, if adopted. In such case, the commission shall prescribe the form of questions in such a manner as will clearly indicate the effect of the approval of such questions. All amendments to the charter shall be separately submitted. The clerk of the city council shall, within five days after the filing of a new charter proposed by a charter commission or within five days after final enactment of an ordinance by the city council, as aforesaid, providing for submission of amendments to its charter, certify an exact copy of the text of such new charter or amendments, together with the necessary ballot questions, to the county board of elections of the county wherein such city is situate. The county board of elections shall cause the said ballot questions to be properly printed on the ballots or ballot labels.
