"We're satisfied with this ruling. There's a before and an after the Zamudio case," said Rolando Jimenez, president of the Gay Liberation and Integration Movement.
"It generated such outrage because of the brutality, the hate, that it helped raised awareness," Jimenez said. "We've witnessed a cultural change that finally led to an anti-discrimination law."
The law had been stuck in Congress for seven years, but President Sebastian Pinera put it on the fast track after Zamudio's murder. The law adopted last year enables people to file anti-discrimination lawsuits and adds hate-crime sentences for violent crimes.
Zamudio, a clothing store salesman, was the second of four brothers. He had hoped to study theatre.
"Nothing can change the tremendous pain suffered by Daniel's parents," presidential spokeswoman Cecilia Perez said. "But there's no doubt that today some tranquillity has finally reached their hearts. It's the tranquillity that comes with justice."
