In May, the Senate rejected Goodwin Liu as a nominee to the 9th Circuit Court of Appeals.
Now, California Gov. Jerry Brown wants to see the UC Berkeley law professor on the state's Supreme Court.
Liu was once a clerk for Supreme Court Justice Ruth Ginsburg and some consider his viewpoints to be radical.
When President Barack Obama nominated Liu for the federal court appointment, conservatives argued that he's a "judicial activist."
Liu, 40, has never served as a judge or trial lawyer, and has supported liberal groups like the American Civil Liberties Union.
"Goodwin Liu is a judicial activist who, judging from his writings, would bend the constitutional text to serve his policy goals," said Jordan Sekulow, director of policy and international operations for the American Center for Law & Justice.
"Apparently, Gov. Brown thinks that Liu's kind of activism is what California needs from its Supreme Court," he added.
Randy Thomasson, president of Save California, feels Liu's appointment would "a bad loss for families."
"I'm speaking out against Liu to educate voters on the difference between a good judge and a bad judge," he said in a recent blog post.
"Sadly, there is a growing group of unpatriotic liars who raise their right hands and swear to support and defend the specific, written constitutions of California and of the United States, but they intend nothing of the sort," Thomasson told the Metropolitan News. "Goodwin Liu is one of these un-American deceivers."
Liu was nominated Tuesday to replace Justice Carlos Moreno, who stepped down in February. His confirmation hearing is set for Aug. 31.
