A unanimous New Jersey Supreme Court on Wednesday turned back a health insurance carrier’s quest for information about medical providers’ ownership structures and business practices, finding no basis in statute or contract.

“We may not, under the guise of statutory construction, expand its scope in the boundless fashion plaintiff seeks merely because plaintiff has formed the belief that the defendants may not have complied with the requirements of other statutes or regulations,” the court said in Selective Ins. Co. of America v. Hudson East Pain Management, A-105-10.
