The Delaware Supreme Court has reversed a Chancery Court decision that assessed only $1 in damages for a wind-energy development firm’s refusal to cash out an investor after it offloaded part of the company in a $1.8 billion asset sale, ruling that the remedy had “no support” in the courts’ case law.

The ruling, from a full panel of the state’s five justices, came Thursday in a breach-of-contract suit stemming from Leaf Clean Energy Co.’s $30 million investment in Invenergy Wind in 2008. Vice Chancellor J. Travis Laster last year found that Invenergy had breached an agreement to provide Leaf a hefty return on its initial investment if it conducted a partial sale without Leaf’s consent.
