Judge Andrew Napolitano says the New York Court of Appeals’ ruling on Fox News reporter Jana Winter is a “tremendous victory for freedom of speech.”

The highest state court in New York today ruled that Winter does not have to return to Colorado to testify about her sources for a story on the Aurora movie theater attacker James Holmes.

Judge Napolitano: Jana Winter Will 'Never Reveal Who Her Sources Are'

Napolitano said the New York Court of Appeals’ ruling “has firmly established the public policy of the state of New York as the most pro-First Amendment, pro-freedom of speech policy in the United States of America.”

“The state of New York basically said to Jana Winter and to all of our colleagues in the journalism industry, 'You can disregard a subpoena from a judge of another state if you are a New York journalist because the New York law will protect you,'” he said.
