Firearm companies have warned the Supreme Court that Mexico's billion-dollar lawsuit could be the end of their business.

The justices will consider whether a 2005 law that gives gun makers broad immunity applies in the case, which accuses them of complicity in supplying cartels with weapons.

The U.S. Supreme Court agreed on Friday to hear a bid by U.S. gun maker Smith & Wesson and firearms wholesaler Interstate Arms to throw out Mexico's lawsuit accusing them of aiding the illegal trafficking of firearms to Mexican drug cartels.
