The Delaware Supreme Court has issued an opinion that clarifies just when the rule in the landmark case Kahn v. M & F Worldwide Corp., or MFW, may be applied in various types of deals involving controlling shareholders and requires approval from both a committee of individually independent directors and a vote among minority shareholders.

The derivative case brought by Match Group Inc. shareholders and decided on Thursday has been closely watched by Delaware attorneys because it raised questions on how and when MFW applies. Those questions hold weight for litigators because they affect when shareholder plaintiffs have the burden of proof in the Court of Chancery, but they’ve also drawn attentions from corporate lawyers advising clients on how to get deals approved.
