Greenberg Traurig has guided U.S.-based firm KBR Inc to victory against the Serious Fraud Office (SFO) in the U.K. Supreme Court, in a hotly-anticipated judgement announced on Friday. 

The SFO had sought to make KBR, a U.S. engineering, procurement and construction company with U.K. subsidiaries, hand over materials held outside of the U.K. as part of a fraud investigation.
