According to attorney Troy Martin, Los Angeles Superior Court Judge Daniel Murphy said in a ruling Wednesday that giving Kasem food and fluids would be harmful and cause more pain for the 82-year-old former radio personality and voice actor.
Kasem suffers from a form of Lewy body dementia, which has symptoms similar to Alzheimer's disease.
His daughter Kerri Kasem initially implemented the end-of life measures on June 6.
On Monday, Murphy had ordered the reinstatement of feeding and other care while a court-appointed attorney consulted with Kasemand doctors. The reinstatement has now been reversed according to Martin, who serves as one of Kerri Kasem's lawyers.
The New York Daily News, which first reported the ruling, said Kasem's wife of 34 years, Jean Kasem, stormed out of court after Murphy's decision was announced.
Jean and Kerri Kasem have been involved in a dispute over care for the entertainer, best known as the long-running host of several countdown radio programs and as the voice of Shaggy in the "Scooby-Doo" franchise.
