The Arizona Supreme Court has denied a prosecutor's appeal regarding the state's fake elector case against former White House chief of staff Mark Meadows, former New York City mayor Rudy Giuliani, and other defendants connected to the 2020 presidential election.

The court's decision requires the case to be returned to a grand jury, representing a procedural setback for Arizona Attorney General Kris Mayes, a Democrat, who has been working to advance the prosecution through the court system.

The case centers on allegations related to efforts to overturn the 2020 presidential election results in Arizona through the submission of alternative electors. Meadows served as chief of staff to former President Donald Trump, while Giuliani was Trump's personal attorney during the period in question.

Mayes' office indicated it will present the case in its entirety to a new grand jury rather than abandon the prosecution. The attorney general's office has characterized this as part of ongoing efforts to pursue accountability related to the 2020 election.

The decision marks another procedural hurdle in what has become a complex legal case involving multiple defendants and allegations stemming from the aftermath of the 2020 presidential election in Arizona.
