A Delaware Chancery Court judge has issued a preliminary injunction barring a company from servicing the accounts of about 55 customers it had allegedly gained after raiding the staff of a rival.

Vice Chancellor J. Travis Laster said Thursday it was “reasonably probable” that affiliates of the Lockton Cos. would succeed at trial on their claims of tortious interference against Alliant Insurance Services Inc., which it said had organized the “en masse” resignation of 26 employees in order to start a competing office in Denver.
