Whenever a proposed constitutional amendment or other State-wide ballot question shall be submitted to the electors of the Commonwealth in referendum, the Attorney General shall prepare a statement in plain English which indicates the purpose, limitations and effects of the ballot question on the people of the Commonwealth. The Secretary of the Commonwealth shall include such statement in his publication of a proposed constitutional amendment as required by Article XI of the Constitution of Pennsylvania. The Secretary of the Commonwealth shall certify such statement to the county boards of elections who shall publish such statement as a part of the notice of elections required by section 1201¹ or any other provision of this act. The county board of elections shall also require that at least three copies of such statement be posted in or about the voting room outside the enclosed space with the specimen ballots and other instructions and notices of penalties. In election questions which affect only one county or portion thereof, the county board of elections shall fulfill these requirements in the place of the Attorney General and the Secretary of the Commonwealth.
