A computer programmer had to have emergency surgery to remove a clot from his brain after he was forcibly ejected on to the street from the Judge Roy Bean's disco in Dublin city centre.
Mr Kevin Daunt, who spent 26 days in hospital, told a jury at Dublin Circuit Criminal Court he was frog-marched from the premises with his left-hand pinned behind his back by a security man who had admitted him a few minutes earlier.
He said one tooth was broken when his face was rammed into part of the door as he was being pushed forward at speed and he was propelled out in such a way that his head hit off a bollard.
He was taken to hospital by Dublin Fire Brigade Ambulance.
Mr Paul Burke (45), St Finian's Grove, Lucan, has pleaded not guilty to assault causing harm to Mr Daunt, from Longlands, Swords on June 18th, 2001.
Mr Daunt told Mr Robert Barton, prosecuting, that he had a few drinks in several bars with the intention of going on to a late-night function in the Gaiety Theatre. He decided to see what Judge Roy Bean's looked like as he had not been there for some time.
He was admitted by the bouncers and decided to have just one short drink, a tequila, instead of a pint. He was about to drink it when tapped on the shoulder by Mr Burke who said he had too much to drink.
Mr Daunt said he had no objection to leaving and replied "okay" but just as he turned to go, Mr Burke pinned his left arm behind his back before pushing him towards the door.
Mr Daunt suggested to Mr Michael Dreelan, defending, that Judge Roy Bean's disc jockeys could hardly be described as "independent witnesses" because they were employees.
He denied having a pint glass in his hand or annoying other customers when asked to leave.
The hearing continues.
