The star initially filed suit against creator Marc Cherry and producers at ABC and Touchstone in 2010, claiming her Tv character was killed off in 2009 after she complained to show bosses that Cherry had hit her on the head during a rehearsal in September, 2008.
Her sexual harassment, assault and wrongful termination allegations were reduced to wrongful termination and battery before the trial, while Cherry was dropped as a defendant.
The case was eventually ruled a mistrial in Sheridan's favour.
An appellate court later determined the trial judge should have issued a different verdict and suggested Sheridan re-file under California's labour code, which she did - only for her case to be disallowed last November (13) because she had waited too long to take action.
However, in January (14), Los Angeles Superior Court judge Michael Stern gave Sheridan hope by granting a motion for reconsideration, which was then declared invalid by appeal court judges last month (Aug14), amid allegations Stern no longer had the jurisdiction to revive the matter.
The issue returned to court on Tuesday (23Sep14), when Stern officially vacated his order for a new trial.
Sheridan's lawyers are still determined to fight the case and are working on an appeal.
