Sara Mansoori KC, defending the former comedian, said her client is “in a highly vulnerable position” and has “not been in a position to give us instructions on any appeal”.
She said Walliams had tried to kill himself when he was informed about the allegations in May. He then repeated this attempt in July.
He is currently being cared for in hospital, having absconded from a clinic in the summer.
Lawyers for Walliams said the attempts in his life were out of fear of public shame rooted in childhood trauma, as opposed to any form of guilt.
Walliams first came to prominence on the comedy shows Come Fly With Me and Little Britain, and was later a judge on Britain’s Got Talent.
Alongside his television work, Walliams also sold more than 60 million copies of his children’s books, including Gangsta Granny and The Boy In The Dress.
He was dropped by his publisher HarperCollins in December 2025, following allegations of sexual misconduct, which he strongly denies.
Alton Towers also closed its World Of David Walliams attraction, inspired by his best-selling books, last week.
