Republicans have indicated they do not intend to swear in Sen. Jim Brewster during Tuesday’s ceremony, Democrats said.

HARRISBURG, Pa. (AP) — A day before Pennsylvania state lawmakers will be sworn in for a new two-year session, state Senate Democrats said Monday that the Republican majority is trying to “steal an election” by objecting to letting a Democratic member take his seat for a fourth term.

The dispute revolves around the election of Democratic Sen. Jim Brewster of Allegheny County and could leave the decision on who to install in the Senate district to a majority of senators.

The contest between Brewster and Republican challenger Nicole Ziccarelli hinged on court decisions that said mail-in ballots that lack a handwritten date on the ballot envelope is not a reason to disqualify someone’s vote.

Senate Minority Leader Jay Costa, D-Allegheny, called the Republicans’ refusal to swear in Brewster during Tuesday’s ceremony “unlawful” and suggested that his caucus will go to court.

Republicans were trying to “steal an election” in what Costa framed as a continuation of “the Trump playbook. It’s about abusing the process that’s in place.”

Costa also pointed out that U.S. House Speaker Nancy Pelosi swore in Rep.-elect Mariannette Miller-Meeks, R-Iowa, even as her Democratic opponent’s challenge to the election results remains under review by the House.

The Senate’s top Republican, President Pro Tempore-elect Jake Corman, R-Centre, called it a “fairly unique, if not unprecedented situation.”

The Senate has the constitutional authority to ensure its members meet certain qualifications in the Constitution, Corman said, although Democrats say those qualifications are limited to age and residency and that Republicans are abusing their power.

Still, Corman noted that Ziccarelli has filed a complaint with the Senate and a lawsuit in federal court in an “extremely close” election affected by court rulings.

“I think this unique set of circumstances dictates that the Senate review it and take very seriously the contest,” Corman said.

He did not say how long the Senate will need to review Ziccarelli’s filing before voting, or how long the Senate is willing to leave the seat vacant.

Brewster beat Ziccarelli by 69 votes in the Nov. 3 election, according to state-certified returns last month.

On Friday, she filed a roughly 500-page complaint with the Senate that Brewster’s lawyer, Cliff Levine, said “completely violates” any established procedure in state law to contest an election.

Corman, however, said that, in the Senate, “the Senate determines what is proper and what is not proper and that is determined by 26 members of the Senate.”

In late November, Ziccarelli sued in federal court in Pittsburgh to overturn the election result. Briefs are due later this week, but the judge gave no deadline to rule.

In the lawsuit, Ziccarelli is asking a federal judge to effectively throw out 311 mail-in ballots counted in Allegheny County that lacked a handwritten date on the outer ballot envelope. Counting those ballots provided the margin to give Brewster a victory.

The state Supreme Court, in a 4-3 decision, ruled in November that it would not apply the handwritten date requirement in the just-passed election, and said the lack of a handwritten date is not a compelling enough reason to throw out the ballot of an eligible voter. State law says the voter shall “fill out, date and sign” a declaration on the outside envelope.

The state Senate district also includes part of Westmoreland County, which decided against counting 343 mail-in ballots that lacked a handwritten date on the outer envelope.

Ziccarelli’s lawsuit says the different treatment of voters in different counties violates their constitutional rights.

Lawyers for Brewster, the Democratic Party and the state say the federal court lacks jurisdiction to overturn a state-court decision. They also say Ziccarelli lacks standing to sue and that throwing out the ballots of those 311 Allegheny County voters would violate their constitutional rights.

Even so, the conflicting decisions of the counties to count certain mail-in ballots does not violate the constitutional rights of voters, they say.

The outcome will not change the balance of power in the 50-seat state Senate, where Republicans have 28 returning members. There is one independent and 21 Democrats, counting Brewster.
