PHILADELPHIA - A trial court abused its discretion in failing to recognize that a partner firm in limited liability company (LLC) had a fiduciary duty to both the LLC and the other member firm, a Third Circuit U.S. Court of Appeals panel ruled May 11, vacating the lower court's denial of a preliminary injunction related to the operation of two websites that the parties previously operated together (Health and Body Store LLC, et al. v. Justbrand Limited, et al., No. 11-4132, 3rd Cir.; 2012 U.S. App. LEXIS 9604).
