SYDNEY, Australia -- Australia's highest court has cleared the way for a radio station to face penalties over a prank call to a London hospital where the Duchess of Cambridge was being treated. A nurse who transferred the call committed suicide after it was broadcast.

Two Australian DJs from radio station 2DayFM impersonated Queen Elizabeth II and Prince Charles when they phoned the hospital in 2012 to ask about Kate's condition.

Nurse Jacintha Saldanha took the call and passed it on to a colleague who described the condition of Kate, then pregnant with her first baby. Three days after the call was broadcast, Saldanha was found dead in her room.

Australia's High Court on Wednesday ruled that the country's broadcasting watchdog has the power to find that the radio station broke the law.
