The High Court has dismissed a claim made by a Liverpool man who fell out the window of a Cork hotel in 2009 for damages of almost £1.5m.
Mr Justice Bernard Barton said video evidence showed that Jason Platt's injuries had been grossly exaggerated and his evidence was not honest, credible or reliable.
On Valentine's weekend 2009, Mr Platt and his fiancée were staying in the Old Bank House in Kinsale.
The 43-year-old said he was smoking out the window when he fell eight metres from a third-floor bedroom.
He blamed the lack of a safety guard on the window.
Mr Platt sought damages of just under £1.5m to adapt his home, get a new car and hire a cleaner and handyman.
He told the court that he had been crippled by the accident.
He said he was mostly housebound and needed a wheelchair and crutches to get around.
However, a private investigator acting for Aviva Insurance captured video footage of Mr Platt walking, driving and shopping.
Mr Justice Barton dismissed the claim, saying the video evidence was in stark contrast to how Mr Platt had presented to medical experts.
He said he was satisfied that his account of his disability was grossly exaggerated.
Speaking afterwards, Aviva Insurance said false or exaggerated claims impose huge costs on insurance customers.
The company described the judgment as a victory for its customers and the economy.
