"Respondent Luzerne County Board of Elections respectfully moves for the recusal of Justice Amy Coney Barrett from this matter pursuant to Supreme Court Rule 21," the court documents said on Tuesday. "This recusal is compelled since Justice Barrett’s 'impartiality might reasonably be questioned,' 28 U.S.C. § 455, given the circumstances of her nomination and confirmation."
The Pennsylvania Republican Party has been trying to challenge the Pennsylvania Supreme Court's decision to extend the mail-in ballot deadline in the state to November 6 - three days after Election Day. The Republican Party and US President Donald Trump have said the practice of mailing in ballots and extending deadlines may result in vote harvesting and electoral fraud.
On October 19, the US Supreme Court rejected a bid from the state's Republican Party seeking to reverse the state's decision. However, on Saturday, the Pennsylvania Republican Party asked the US Supreme Court to fast-track a review of the Pennsylvania Supreme Court's decision to extend the deadline for mail-in ballots.
Barrett was confirmed by the US Senate as a Supreme Court Associate Justice on Monday.
