(Reuters) — A U.S. judge has ordered UBS Group A.G. to face a lawsuit by a former bond strategist who said he was fired in retaliation for refusing to publish misleading research reports and complaining about being pressured to do so.

In a decision made public on Tuesday night, U.S. District Judge Katherine Polk Failla in Manhattan said Trevor Murray could try to prove that whistleblowing was a factor in his February 2012 firing, and that UBS' actions violated the Sarbanes-Oxley corporate governance law.

Mr. Murray claimed UBS officials pressured him to issue skewed, bullish research on commercial mortgage-backed securities in order to support the Swiss bank's trading and underwriting operations.

"Plaintiff believed that efforts to pressure him into publishing biased and inaccurate, but ostensibly independent, reports" were illegal, and a reasonable jury could find that his resistance was a factor in his firing, Judge Failla wrote.

The judge's decision, which was released in redacted form, is dated March 31. Mr. Murray has sought back pay and other damages.

UBS spokeswoman Erica Chase said in an email: "While we are disappointed in this decision, we continue to believe that the claims have no merit and we will continue to vigorously defend the case."

Robert Stulberg, a lawyer for Mr. Murray, was not immediately available for comment on Wednesday.

In seeking to dismiss the lawsuit, UBS said Mr. Murray's termination was part of a cost-cutting drive that eliminated thousands of jobs after the company had reported lower-than-expected revenue and a $2 billion loss from unauthorized trading by "rogue trader" Kweku Adoboli.

Mr. Murray was fired fewer than nine months into his second stint at UBS. He had worked for the bank from May 2007 to September 2009, when he was let go due to cost-cutting prompted by the global financial crisis, according to court papers.

The case is Murray v. UBS Securities L.L.C. et al., U.S. District Court, Southern District of New York, No. 14-00927.
