A group of Pennsylvania state senators and ad agency executives is trying to overturn the state lottery’s recent award of its advertising duties.

The account was handed to MARC USA in Pittsburgh, ending the 25-year tenure on the business by Interpublic Group unit Tierney Communications.

However, the lawsuit claims the switch of agencies was unfair. It demands that the Department of Revenue, which manages the lottery, be forbidden from working with MARC and forced to start another review.

The ex-incumbent’s founder Brian Tierney is one of twelve plaintiffs in the suit. Seven others are executives from companies that work with Tierney, while a further two are state senators Vincent Fumo and Joseph Conti.

They claim the Department of Revenue removed Tierney from the account in revenge for the agency’s cooperation with the state Auditor General’s Office in a recent investigation.

Tierney, claims the lawsuit, gave information “adverse to Lottery officials and which supported evidence of the Lottery's mismanagement and improper administration of Lottery funds.”
