The World: New York - Valassis awarded $300m payout from DM rival

News America Marketing, the News Corporation-owned direct mailing business, has been told to pay out $300 million to its rival company Valassis, after a court found the company liable of tortuous interference and inflicting unfair competition.

Valassis, a major player in the inserts and coupons business, claimed that News America Marketing's presence in the market was causing "an uneven playing field" and was therefore guilty of breaking the Unfair Competition and Unfair Practices Acts.

A Michigan trial court jury sided with Valassis. However, News America Marketing has confirmed it will appeal against the decision.
