The U.S. Supreme Court Saturday reinstated Arizona's "ballot collection" law, which makes it a felony to collect early ballots.
Democrats say this move could negatively impact voter turnout because thousands of voters, especially minorities, rely on others to collect and deliver ballots, according to CNN.
The law was enacted earlier this year and was blocked by the 9th U.S. Circuit Court of Appeals on Friday. But, Saturday's ruling reinstated the ban that was lifted for roughly 20 hours.
"It is no secret that ballot collection and delivery has been particularly beneficial for Arizona's minority voters, and legislators who have not traditionally enjoyed broad support in those communities have repeatedly tried to restrict it," Democratic lawyer Marc Elias argued, according to CNN.
Proponents of this law, many of which are Republicans call the practice "ballot harvesting," and say it allows for potential voter fraud.
Arizona's Secretary of State, Michele Reagan, applauded the Supreme Court's move.
"We are extremely pleased the Supreme Court reversed the ninth circuit's decision," Reagan said in a statement to CNN. "This commonsense law simply ensures ballot security in the state of Arizona and we're relived that there will be no changes to the law this late in the election cycle."
The Arizona Republican Party joined Reagan, saying the Supreme Court's move would help ensure a "fair and transparent election."
Despite criticism, Arizona's law is not that different from many other states. Twenty-six other states have a ban on "ballot harvesting" and 13 consider it a felony, according to SCOTUSblog.com.
