Since a Wisconsin airline is “directly doing business” in New York, it was obliged to give a copy of its shareholder list to a competitor that had purchased its stock to facilitate a hostile takeover, a Manhattan appeals court has ruled.

Reversing a lower court’s finding, the Appellate Division, 1st Department, said in AirTran v. Midwest Air Group, 600225/07, that because the Midwest Air Group’s subsidiary was “undisputably bound by the law of New York and subject to its jurisdiction, by virtue … of its registration to do business in New York,” it was required to turn over the information to AirTran.
