Energy Transfer LP will have to move forward with paying $410 million for a broken $33-billion deal with The Williams Companies Inc., $99 million in prejudgment interest and $92 million more in legal fees, the Delaware Supreme Court concluded Tuesday.

The 58-page opinion by Justice Christopher Griffiths is a win for the Cravath, Swaine & Moore and Morris, Nichols, Arsht & Tunnell team that represented Williams Companies, and it ends a seven-year legal battle between the two pipeline companies, other aspects of which the Supreme Court had already considered and upheld by the time this appeal was argued in July.
