Thomas Wallerstein Thomas Wallerstein of Venable

In court papers filed Thursday, Brunswick Rail Management accused its former CEO and the prominent law firm Venable of altering and deleting evidence in a trade secrets dispute.

Brunswick filed a contempt of court motion and a motion for spoliation sanctions in the U.S. District Court for the District of Connecticut against former CEO and New Canaan resident Paul Ostling.

The underlying case claims Ostling relayed confidential information and trade secrets to creditors who could use the information to hurt Brunswick's bargaining position in a $600 million debt restructuring.
