Allied-Lyons filed suit against Hiram Walker.

The British firm is seeking to force Hiram Walker Resources to sell its liquor business to Allied-Lyons and asks for the equivalent of $720 million in punitive damages. Hiram Walker initially agreed to sell its liquor unit for about $2 billion but later withdrew from the agreement after being taken over by another company, Gulf Canada Corp., in April. The lawsuit, filed in Ontario, Canada, also asks for monetary damages to compensate for the sale’s delay.
