The Appellate Division, First Department, on Thursday ruled that a company that provides information about distressed businesses to high-end institutional subscribers is exempt from having to disclose the names of its sources, overturning the trial court's decision.

The appellant, Murray Energy Corporations, has vowed to continue litigating the suit.

Bloomberg LP, Reuters, Dow Jones & Co., The Financial Times, Politico and several other large media companies had joined as amici curiae for the newsletter publisher.
