The actress first sued in 2010, claiming that she'd been wrongfully fired in 2009 when she complained that Cherry hit her in the head during a 2008 argument.
A judge declared a mistrial in March 2012 when a jury couldn't reach a verdict. They had deadlocked 8 to 4 in Sheridan's favor.
In August 2012, an appeals court ruled that Sheridan hadn't been fired. Instead, Touchstone and ABC had decided not to renew her contract.
Stern denied Sheridan's request for a new trial against Touchstone earlier this month, but appears to have changed his mind for reasons that aren't yet clear. Touchstone plans to appeal the decision.
