LONDON — A British court Monday gave the parents of 11-month-old Charlie Gard a chance to present fresh evidence that their terminally ill son should receive experimental treatment.

The decision came after an emotionally charged hearing in the wrenching case, during which Gard’s mother wept in frustration and his father yelled at a lawyer.

Judge Nicholas Francis gave the couple until Wednesday afternoon to present the evidence and set a new hearing for Thursday in the case that has drawn international attention.

But the judge insisted there had to be “new and powerful” evidence to reverse earlier rulings that barred Charlie from traveling abroad for treatment and authorized London’s Great Ormond Street Hospital to take him off life support.

“There is not a person alive who would not want to save Charlie,” Francis said. “If there is new evidence I will hear it.”

Charlie suffers from mitochondrial depletion syndrome, a rare genetic disease that has left him brain damaged and unable to breathe unaided. His parents want to bring him abroad for experimental therapy, which they say offers their son a chance of improvement.

But British and European courts have sided with the hospital’s decision that the 11-month-old’s life support should end, saying therapy would not help and would cause more suffering.

The application came after both Pope Francis and President Trump fueled international attention to the case, with hospitals in Rome and the U.S. offering to provide Charlie the experimental therapy.
