A landmark court ruling could allow one of Northern Ireland’s most notorious killers to challenge her conviction.

Double murderer Hazel Stewart was convicted under the controversial ‘joint enterprise’ law.

On Thursday, the UK’s highest court said the law may have been wrongly interpreted by judges for 30 years.

The decision could pave the way for hundreds of prisoners to seek appeals.

They include Stewart, convicted in 2011 of murdering her husband Trevor Buchanan and Lesley Howell in a joint enterprise with her ex-lover Colin Howell.
