Iraqi government officials and American analysts have asserted that Mr. Galbraith’s dual role during the constitutional negotiations implied a conflict of interest, since the provisions he championed could have increased the value of his own interests. But he has rejected such claims, saying that he was merely helping the Kurds press their long-stated policy goals. “So, while I may have had interests, I see no conflict,” Mr. Galbraith said last year.

DNO said that while the court did not formulate the award as a specific dollar value, the company was able to calculate its likely range. The award fell between the $12 million proposed by DNO and the $144 million proposed by the two claimants, the company said.

Tracey Brinson, a spokeswoman for Porcupine, a company that records in Delaware from 2009 show is registered to Mr. Galbraith, said, “While we do not know the size of the award, it is related to the value created for DNO’s shareholders and the people of Kurdistan.”

When asked whether DNO now had second thoughts about having hired Mr. Galbraith, given his dual roles at the time, a spokesman for the company, Tom Bratlie, said: “I see no point in regretting anything. What is important is that we are fully financially able to cover this and that we are able to put this thing behind us and to continue to develop the company.”
