Double Jeopardy

Series 1 - Episode 2 Double Jeopardy



A long, anguished and harrowing campaign by a mum eventually led to the overturning of an 800-year-old British law – the so-called double jeopardy rule, that prevented anyone who had been cleared once from being tried twice for the same crime.

But Ann Ming was indomitable after the murder of her daughter Julie Hogg in Billingham, Teesside, in 1989. She spent 15 years lobbying Parliament to scrap the law and she talks here, passion undimmed, as she recalls the horrors of losing her adored 22-year-old daughter. Police initially insisted that Julie, who had a young son, was a missing person but they eventually found her body behind the panelling of the bath at her home.

Ann Ming won high level support for her battle for justice after a local man, Billy Dunlop, was tried but not convicted of Julie’s killing and later boasted about committing the murder.


The stories of murder investigations and their extraordinary consequences, which overturned laws, transformed police interrogation and revolutionised forensic detection. The second episode focuses on the story of the murder of Julie Hogg, a single mother from the small town of Billingham in Teesside. The programme looks back at Julie's mother Ann's campaign to challenge the 800-year-old law on Double Jeopardy, after a jury failed to convict Julie's former boyfriend Billy Dunlop. As this episode traces the twists and turns of Ann's campaign, the story of other cases that benefited from the legal changes are also explored.
