The ACLU and the Campaign Legal Center have filed an emergency petition with the Arizona Supreme Court to extend the deadline for voters to correct issues with mail-in ballots, citing potential disenfranchisement of tens of thousands of voters due to delays in notifications and ballot processing. Currently, Arizona law allows voters only until 5 p.m. on the Sunday after election day to rectify ballot defects, a deadline the petition seeks to extend by up to four days. This legal action comes as over 250,000 mail-in ballots remain unverified, primarily in Maricopa County, raising concerns about voters' ability to address issues within the original timeframe. Arizona Senate President Warren Petersen has announced plans to intervene in the lawsuit, opposing any extension that could delay election results further. He emphasized the need to adhere to existing laws to ensure timely election outcomes. The situation is highlighted by ongoing tensions around Arizona's election integrity and the potential impact on upcoming races.
