Democratic lawmakers on Tuesday said they would introduce legislation that would effectively strike down a Supreme Court decision that made it more difficult for workers to prove age bias lawsuits. In June, the Supreme Court held that plaintiffs in such cases must prove that age was a deciding factor in adverse employment decisions. The previous standard held plaintiffs to a less strict burden of proof.

"Three Democratic Congressional committee chairmen said Tuesday that they would move to overturn a four-month-old Supreme Court ruling that made it significantly harder for workers to win many age discrimination cases.
The three chairmen criticized the court’s decision in a case involving a 54-year-old man who was demoted, saying the ruling flouted Congress’s intent and created unfair obstacles to the victims of age discrimination."
