U.S. Bankruptcy Court Judge Robert Faris last month denied Hawaiian Airlines’ request for a preliminary injunction to suspend inter-island service by Mesa Air Group’s Go! subsidiary, citing Hawaiian’s failure to meet the “stringent standard” required for such a severe measure. Although Faris found that Mesa copied proprietary information it obtained during attempts in 2004 to buy into then-bankrupt Hawaiian, he said that Hawaiian failed to prove it suffered irreparable harm as a result of Mesa’s use of the data to build a business model for Go! Nevertheless, he added that “the evidence raises real doubts about the propriety of Mesa’s conduct,” and said Hawaiian should feel free to pursue the injunctive relief as part of a final judgment. The court has set an April trial date for a lawsuit filed by Hawaiian that seeks monetary damages from Mesa.
