Goodwin Liu, a law professor whose confirmation to a federal appeals court was blocked in the U.S. Senate, has been appointed to serve as a justice in California's Supreme Court by Governor Jerry Brown.

Liu's nomination came on Tuesday. While Democrats support Liu's judicial philosophy, Conservatives oppose him.

Liu, 40, is a constitutional law professor at the University of California, Berkeley, and was nominated by President Obama to serve as a judge on the 9th U.S. Circuit Court of Appeals in September last year.

Supreme court justices in California serve 12-year terms.
