Reeves, 75, and his attorneys are fighting for another shot at the stand your ground law.
Reeves claims he was in fear for his life during the 2014 shooting, in which he is accused of shooting Chad Oulson, stating he thought he was in danger.
Detectives say an argument took place in the theater because Oulson was texting.
In 2017, a judge denied the stand your ground argument in this case.
However, the defense argues that the stand your ground law was slightly changed just shortly after the incident happened, the new law shifts the burden of proof from the defense to the prosecutors.
Reeves faces a second-degree murder charge in the 2014 shooting and in a hearing Friday, the judge decided to take the 2019 trial date off of the calendar until the Florida Supreme Court decides if the old or new version of the law will apply to the movie theater shooting.
