An urgent rule change by the Corrections Department which banned smoking in prisons has been ruled unlawful by a High Court judge.
Justice Brewer said that Corrections went beyond its powers when it banned tobacco and smoking equipment last year.
The ruling was the second court victory for career criminal Arthur Taylor, who has led the battle against the anti-smoking rules.
Last year, Mr Taylor successfully challenged a blanket ban on smoking introduced in July 2011. The High Court ruled in December that this ban was unlawful.
Corrections responded by introducing regulations to ban tobacco and smoking equipment. Mr Taylor again challenged this in the High Court.
