Antonio Lopez Chaj, 43, appeared at a news conference with lawyers who announced the award handed down against a security company in Torrance Superior Court.
It was among the largest damage awards ever given to one person in California, the lawyers said.
They said they expect an appeal and there could be settlement negotiations before Lopez Chaj receives anything.
Lopez Chaj cannot speak, needs assistance to walk, eat and take care of himself and requires 24 hour-a-day help.
He had to be supported by relatives at the news conference. When he took off a baseball cap which was hiding his injuries, gasps could be heard from people present.
“His skull is like a pie with 25% cut out of it,” said lawyer Federico Sayre.
Chaj was attacked at a mid-Wilshire bar after trying to intercede in an attack by a bartender and security guard on two relatives who were with him.
Lawyers said an unlicensed, untrained security guard beat Chaj with a baton, kicked him in the head eight times, and smashed his skull against pavement four times.
“It was truly a horrendous and brutal beating by a guy who shouldn’t have been working at all,” said Sayre, who represented Chaj along with Fernando Chavez, the son of famed civil rights leader Cesar Chavez.
The security guard, Emerson Quintanilla, and the bartender-manager who sparked the attack, have disappeared without a trace, Sayre said.
“I think the man went crazy, lost his mind,” he said of Quintanilla. “It was a species of road rage.”
Sayre said the confrontation begin Apr 20, 2010, when Chaj, his brother, and two nephews, who all worked as house painters, went to Barra Latina, a local neighbourhood bar.
One of the relatives got into a dispute with the bartender-manager who came after him with brass knuckles, Sayre said. Quintanilla, who was working for DGSP Security and Patrol Services, began kicking and beating members of the group.
Chaj tried to intervene and said, “Stop beating my nephews.” At that point, Sayre said, the guard beat Chaj into unconsciousness.
Part of his skull was gone when he reached the hospital. “They saved his life but he has significant brain damage,” Sayre said. “He can’t speak and he requires 24-hour nursing care.”
He said Chaj faces more surgeries.
Phone messages seeking comment left with attorneys for the defendants were not immediately returned.
In civil courts, only nine of the 12 jurors have to agree on a verdict, Sayre said. But this jury was unanimous in finding for the plaintiffs on all claims, and it granted the $58m award the plaintiffs requested
The lawyers requested and secured the judgment for $58m — in economic and medical losses, future medical expenses, lost earnings in addition to pain and suffering.
