The Justice Department’s emergency appeal to the high court said U.S. District Judge Myong Joun in Boston exceeded his authority last month when he issued a preliminary injunction reversing the layoffs of nearly 1,400 people and putting the broader plan on hold.

The Supreme Court is tossing out a $10 billion lawsuit Mexico filed against top U.S. firearm manufacturers alleging the companies fuel cartel gun violence.

The U.S. 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 in the southern neighbor of the United States.

The Supreme Court unanimously rejected Mexico's claims that the gunmakers were exempt from liability generally given to firearms makers in a 2005 law.
