A hearing resumes Friday in a lawsuit challenging the results of an Oklahoma House race where the incumbent won by just 16 votes.
Democrat Paula Roberts has filed a petition that alleges 10 different irregularities make it "impossible to determine with mathematical certainty which candidate is entitled to a certificate of election."
Roberts lost by 16 votes to Republican Rep. Aaron Stiles in the November general election.
The hearing on Roberts' lawsuit began last week but a judge did not issue a ruling. Additional testimony is scheduled for Friday.
Among Roberts' allegations are that ineligible voters were allowed to cast ballots while some validly registered voters were not. Roberts also alleges that absentee ballots were improperly secured and that mistakes were made with both provisional ballots and voting machines.
