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 has supervision over elections.
The Constitution of Pennsylvania requires that the legislative districts for the House of Representatives and the State Senate be redrawn each decade following the federal census. This process is mandated by the Pennsylvania Constitution so that each citizen's vote ultimately carries the same weight in the ballot box.
Article 2, Section 16 of the Pennsylvania Constitution provides for the Commonwealth to be divided into 50 senatorial and 203 representative districts.
Article 2, Section 17 of the Pennsylvania Constitution provides for a Legislative Reapportionment Commission to redistrict both chambers (the state Senate and the state House) in the year following the Federal decennial census. The Commission consists of five members: the four caucus floor leaders, or deputies appointed by each of them, and a chairman to be selected by those members or, if they cannot reach agreement, by the Pennsylvania Supreme Court.
