In a fraud suit over the $3 million sale of a Pennsylvania property to an oil-and-gas company, Pittsburgh-based Tucker Arensberg must turn over additional billing records that could indicate the firm failed to disclose material facts during the underlying transaction, a federal judge has ruled.

U.S. Magistrate Judge Martin Carlson of the Middle District of Pennsylvania, ruling in Prime Energy and Chemical v. Tucker Arensberg, determined the law firm cannot simply redact all of its billing records for the time period during the transaction underlying the lawsuit, but rather must review and provide any potentially material records during the 15 months at issue.
