(CNN) Members of the US women's soccer team scored one of their goals Friday when a federal judge allowed their gender discrimination lawsuit to proceed as a class action.

The US Women's National Team's lawsuit against the US Soccer Federation was filed in March in US District Court in California, with 28 members of the team listed as plaintiffs. A trial is currently scheduled for May 2020.

Friday's class certification decision allows for members of the USWNT to sue the federation collectively -- including any player who reported for national team duty over a specific period of time cited in the lawsuit.

When contacted for reaction, a federation spokesperson said, "U.S. Soccer does not have any specific comment."

The suit alleges US Soccer's payment practices amount to federal discrimination by paying women less than men "for substantially equal work and by denying them at least equal playing, training, and travel conditions; equal promotion of their games; equal support and development for their games; and other terms and conditions of employment equal to the MNT."
