The US Supreme Court on Monday threw out an appeal by Saks Fifth Avenue and Filene's Basement Corp that they should face charges of passing off recycled wool blazers as 10 per cent cashmere. The pair had asked the high court to overturn an earlier decision that dismissed most of the claims made by cashmere maker LW Packard & Co and cashmere makers' trade association the Cashmere and Camel Hair Manufacturers Institute.
