The elderly victim of a convicted rapist has lost a legal bid to make the attacker pay compensation after he won millions on Britain's national lottery while in prison.
But her legal representatives said they would appeal to the House of Lords.
Iorworth Hoare, dubbed the "Lotto rapist" by the media, had no money when he went to jail for life in 1989.
In the event, he spent 16 years in jail and while on weekend leave from prison in 2004 prior to his release he bought a lottery ticket which netted him 7 million pounds ($12.29 million).
His 77-year-old victim had argued Hoare should be made to pay for his "violent and disgusting sexual assault" that left her mentally scarred.
But the appeal was rejected.
At a previous High Court case, a judge ruled Hoare did not have to pay compensation because the woman had made her appeal outside the normal six-year time limit to sue for damages. The judges on Wednesday said they were bound to that decision.
Mrs A - who cannot be named for legal reasons - says she still suffers from the mental torture she endured from serial rapist Hoare's brutal assault on her.
Her lawyer Alan Newman said she was 59 when Hoare attacked her as she walked in a Leeds park in broad daylight in February 1988.
He said Hoare was guilty of a series of sexual assaults on women, including at least two rapes, and was jailed for life at Leeds Crown Court in 1989 for the attempted rape of Mrs A.
She did not sue him for damages at the time because he had no money and any judgment would have been worthless. She received 5,000 pounds from the Criminal Injuries Compensation Board.
