One of the businesses behind the Irish Alliance for Insurance Reform has won a significant court victory over an injury claimant.

William Quilligan sought damages from Supermacs, Ireland's biggest fast food chain, after falling over in one of its Limerick shops.

He alleged the shop floor had been wet and slippery.

However, the circuit court found his fall had been caused by the "couple of joints" he had smoked before entering the premises.

Supermacs founder and managing director Pat McDonagh said he was delighted by the outcome.

McDonagh was one of the main forces behind the alliance's establishment, after his chain of stores was hit by a flurry of fraudulent and exaggerated personal injury claims, causing his premiums to rise dramatically.
