The Arkansas Supreme Court overturned a trespassing decision that barred a labor union from soliciting for members at Wal-Mart or Sam's Club stores nationwide. The court ruled that the Bentonville, Ark., retailer failed to show irreparable harm from solicitations by members of the United Food and Commercial Workers International Union. Wal-Mart contended that UFCW organizers were trespassing and harassing workers in a 1999 suit after the union sent representatives to about 300 Supercenters across the country. A Fort Smith judge granted a permanent injunction in 2002 that prohibited the union from soliciting in Wal-Mart, Sam's Clubs and Neighborhood Market grocery stores in Fort Smith and across the United States.
