The Supreme Court said Monday it would decide if some large drug manufacturers can be sued for billions of dollars on claims they conspired to fix vitamin prices worldwide.
Five foreign companies that purchased vitamins - from Australia, Ecuador, Panama and Ukraine - want to use U.S. antitrust laws to pursue damages.
Lawyers for the drug companies warned the Supreme Court that if that's allowed "new cases from all over the world will flood the federal district courts."
Attorneys for the foreign companies said in their filing that no more than a dozen similar cases have ever been brought in U.S. courts.
At issue is the reach of federal antitrust laws to cover anticompetitive practices in foreign commerce.
