The issue the appeals court will consider is whether Oates should be tried at all for the death of 34-year-old Carlos Olivera. Olivera died after Oates shot him six times in a confrontation over an improperly parked minivan on which Oates had put a "boot."
Oates' attorneys -- Don Colongeli and Jared Newman -- say he should not be tried because he shot Olivera in self-defense. Olivera had approached Oates, who was sitting in his tow truck, with a handgun tucked in his pants.
A Beaufort County Court rejected that argument in March, and Oates' attorneys took their case to appeals court.
Oates' attorneys contend he should not be tried because South Carolina's "Castle Doctrine" allows a person to use deadly force to defend themselves in their homes, vehicles or businesses. Oates was a victim who had no choice but to shoot when Olivera approached his truck armed with a gun, they say.
Never miss a local story.
Prosecutors counter that the Castle Doctrine doesn't apply in the Oates case. Oates fired the weapon he kept in his tow truck after Olivera was no longer a threat -- giving Oates no grounds to claim self-defense, prosecutors have argued.
Olivera's loaded weapon, for which he had a concealed-weapons permit, never was fired, they add.
Both the defense and prosecution acknowledge that the Castle Doctrine creates lengthy delays. It's possible the issue over whether the Castle Doctrine applies could take the case all the way to the state Supreme Court.
"You're going to see this in every homicide case," said 14th Circuit Solicitor Duffie Stone, whose office handled the case before it moved up to the appeals court. Although the Oates case is out of Stone's hands for now, he continues to advocate for changes to the self-defense law.
Oates' attorney Colongeli also said the delay "is, unfortunately, not abnormal."
"We have a client who is also interested in getting this resolved as quickly as possible," Colongeli said.
One of the people most frustrated with the delay -- it's already been 21 months since the shooting -- is Olivera's brother, Nelson Olivera.
"(Oates) is at home doing whatever he wants while my brother is underground," Nelson Olivera said. "A father was taken away from his kids, a hard-working young man who had never in his life been arrested. This was a good man.
"We're never going to forget and we're going to fight all the way to the end," he said.
