The Trump campaign on Sunday asked the US Supreme Court to reverse three decisions by the Pennsylvania Supreme Court, claiming there is a “likelihood” they violate the Constitution and urging the high court to act expeditiously because the presidency “hangs in the balance.”

“This petition … has national importance, and there is a strong likelihood that the State Supreme Court decision violates the Federal Constitution,” read a statement, signed by Rudy Giuliani, President Trump’s personal lawyer.

The petition seeks remedies, “including vacating the appointment of electors committed to Joseph Biden and allowing the Pennsylvania General Assembly to select their replacements,” the statement said.

The three Pennsylvania decisions involve signatures on mail-in and absentee ballots and the denial to observe vote counting at the Philadelphia Convention Center.

The decisions of the PA court “likely changed the result in Pennsylvania and, potentially, the outcome of the overall Presidential election,” the statement argues.

“The Campaign also moved for expedited consideration, asking the Supreme Court to order responses by December 23 and a reply by December 24 to allow the U.S. Supreme Court to rule before Congress meets on January 6 to consider the votes of the electoral college,” it continued.

“The outcome of the election for the Presidency of the United States hangs in the balance because the selection of presidential electors is governed by the Constitution and congressional enactment, in addition to state law enacted by the Legislature.”

The majority of the suits filed thus far in Pennsylvania and elsewhere were denied by judges who said Trump’s legal team did not show concrete evidence of fraud to back up their allegations.

Though Trump had won Pennsylvania in 2016 and his popularity seemed high, his rallies in the state were popular and well attended, Joe Biden won Pennsylvania’s by 80,000 votes. The Trump campaign believes Trump actually received more legitimate votes than Biden.
