Supreme court strikes down Mexico’s lawsuit against US gunmakers

Lawsuit alleged that Smith & Wesson and Interstate Arms aided the illegal trafficking of firearms to drug cartels

The US supreme court on Thursday spared two American gun companies from a lawsuit by Mexico's government accusing them of aiding illegal firearms trafficking to drug cartels and fueling gun violence on the south side of the US-Mexico border.

The justices, in a unanimous ruling, overturned a lower court's decision that had allowed the lawsuit to proceed against the firearms maker Smith & Wesson and distributor Interstate Arms. The lower court had found that Mexico plausibly alleged that the companies aided and abetted illegal gun sales, harming its government.
