Federal Judge: Credit Ratings Not Always Protected Under First Amendment

These agencies had argued that the Constitution protected them from claims they issued inflated ratings on more than $5 billion of securities issued in 2006 and 2007, and backed by loans from former Thornburg Mortgage Inc and other lenders.

But the judge said the ratings were shared with too small a group of investors to deserve the broad protection sought.

"The court rejects the rating agency defendants' arguments that the First Amendment provides any protection to them under the facts of this case," U.S. District Judge James Browning in Albuquerque, New Mexico, wrote in a 273-page opinion.

Browning nonetheless dismissed claims accusing Moody's and Fitch, but not S&P, of misrepresentations, saying the investors did not adequately allege that the two agencies did not believe their ratings, or knowingly concealed their inaccuracy.
