The Arizona Republican Party has filed a lawsuit demanding a hand recount of votes by precinct rather than voting centers, contending that Maricopa County is not following state law.

The lawsuit, announced on Thursday, demands a hand recount of votes by sampling precincts rather than “voting centers,” which Maricopa County provided in this year’s presidential election. Voting centers allow voters from any precinct to cast their ballots.

“There is a fundamental difference between sampling ‘polling centers’ and ‘precincts,’ most notable being the fact that there were only around 175 voting centers in this election but there were 748 precincts,” the Republican Party of Arizona said in a statement, announcing the legal challenge.
