On December 3, a Pennsylvania Republican member of Congress, and several Republican congressional nominees, asked the U.S. Supreme Court to block Pennsylvania from certifying its November 2020 election returns. Kelly v Commonwealth of Pennsylvania. Here is the document. The individuals who filed the case say that the Pennsylvania legislature passed a bill in 2019 allowing no-excuse absentee voting, but that the bill, which was signed into law, violates the Pennsylvania Constitution. They say the Pennsylvania Constitution does not permit no-excuse absentee voting. They say that if the legislature wanted to legalize no-excuse absentee voting, it should have set in motion the process to amend the state constitution.

The Pennsylvania State Supreme Court has already rejected this case. Thanks to Rick Hasen for this news. It is somewhat surprising that Republicans are complaining about the 2019 bill, because the Pennsylvania legislature had and has a Republican majority in each house, so Republicans in the legislature passed it. Update: in the U.S. Supreme Court, the case is 20A98. Justice Alito has asked the Pennsylvania government to respond by December 9.
