19 firms back appeal by Wal-Mart
Intel, Altria, Bank of America and 16 other companies called on the U.S. Supreme Court to hear a WalMart Stores Inc. appeal that seeks to limit class-action lawsuits by workers.
Wal-Mart last month asked the high court to block female employees from suing on behalf of as many as 1.5 million women. The case would be the largest gender-bias suit against a private employer in U.S. history.
Should the court agree to hear the case, it probably would become the most significant business dispute before the justices.
