A California state judge has ruled that 6,000 Black workers at Tesla's flagship assembly plant cannot sue over alleged racial harassment as a class, reversing an earlier ruling in a major victory for CEO Elon Musk's electric vehicle maker. California Superior Court Judge Peter Borkon late on Friday ruled that the 2017 lawsuit could not move forward as a class action because lawyers for the plaintiffs were unable to find 200 class members willing to testify ahead of a trial scheduled for 2026.
