The Delaware Supreme Court on Thursday reversed a Chancery Court decision forcing billionaire William I. Koch to sell his $3 billion energy company so that two private equity firms could recoup their investment in the company.

A full panel of the high court said that Vice Chancellor J. Travis Laster had misconstrued Oxbow Carbon LLC's agreement when he ruled last February that Crestview Partners and Load Line Capital LLC could pursue a full-company sale, which the firms claimed they had bargained for when they invested in Florida-based Oxbow back in 2007.

Laster had applied the implied covenant of good faith and fair dealing to fill gap that, he said, blocked Koch's attempt to thwart the sale. Laster later appointed a monitor to oversee the sale and ordered Koch to pay tens of millions of dollars in damages for derailing the sale in 2016.

William Koch is the brother of the billionaire conservative political activists Charles and David Koch.

However, Supreme Court Justice Karen L. Valihura said no such gap existed and vacated Laster's remedies ruling from August.

“Although Oxbow's handling of the issuances was hardly a model of good corporate governance, [Crestview and Load Line] were highly sophisticated entities with three board members who were capable of reading the LLC Agreement and bargaining for the rights they now seek through litigation,” Valihura wrote in a 47-page opinion.

William Koch said Thursday that he was “pleased that the Supreme Court unanimously agreed with Oxbow on all issues in this litigation.”

“We are evaluating our next steps,” he said in a statement. “Oxbow is a very profitable company and an industry leader. We will continue to provide our clients with the highest quality products and the best service.”

A spokeswoman for Oxbow's Mintz, Levin, Cohn, Ferris, Glovsky and Popeo attorneys, meanwhile, declared the ruling a “full and complete victory.” R. Robert Popeo, who represented Oxbow, directed inquiries to a company spokesman, who did not immediately return a call Thursday afternoon requesting comment.

Attorneys for Crestview and Load Line did not immediately respond to requests for comment.

Laster's ruling had set the stage for Oxbow's sale within a year, and aimed to resolve more than two years of messy Chancery Court litigation, where Koch had accused Crestview and Load Line of conspiring to force him out of Oxbow in order to force a quick sale as commodities prices tanked.

The case, which went to trial in July 2017, also featured wide-ranging allegations of wrongdoing, including assertions from Koch that Crestview had planted a “mole” on the Oxbow board to spy on him and pressure him to resign.

Crestview likewise countered by accusing Koch of mismanagement and boardroom paranoia.

According to court documents, Koch even went so far as to install cameras at company facilities and had hired private investigators to help build his case against Crestview. Surveillance records and other information were turned over to the investors in discovery.

Valihura remanded the case to Laster for further proceedings, though it was not clear Thursday what would be the “next steps” in the litigation.
