Here is a piece of text: UPDATE: RUSELL David Smith who was charged with grievous bodily harm arising from injuries sustained by Shane Smith in an altercation on an Oakey's main street last year has been found not guilty.
The jury took a little of two hours to reach its verdict.
Russell Smith's defence barrister Ben Power had argued that while the defence accepted the complainant man sustained grievous bodily harm, his client had acted in self defence after Shane Smith, a much bigger man, had rushed his client who struck first believing he was about to be hit.
EARLIER: THAT a man who sustained a fractured skull and brain damage during an altercation on an Oakey street suffered grievous bodily harm (GBH) would not be in dispute, the Toowoomba District Court trial of a man charged with causing the injury has heard.
Russell David Smith has pleaded not guilty to the charge arising from injuries sustained by Shane Smith (no relation) after a night out at the Bernborough Tavern on March 5, last year.
Crown prosecutor Shontelle Petrie said Russell Smith was in a group of four who attended the tavern that night where Shane Smith had also been drinking.
When a woman from Russell Smith's group was seen to be dancing "provocatively", Shane Smith had thrown a $20 note in her direction, causing offence and Russell Smith's friend Simon Maddern had punched him, knocking him back into tables and to the floor, leaving him with a bloody nose.
Russell Smith later told police after the pub was closed an angry Shane Smith had approached him and Maddern with clenched fists on the Campbell St footpath nearby.
Russell Smith said he had punched Shane Smith who had fallen to the concrete footpath, hit his head and later woke up Gold Coast University Hospital.
Defence barrister Ben Power told the jury the complainant had mostly recovered but it would not be disputed his injuries amounted to GBH.
However, the issues were whether Russell Smith had acted in self defence in the belief he was about to be struck by Shane Smith and whether it was foreseeable in throwing that one punch such brain injury would result, he said.
The trial before Judge Gregory Koppenol is expected to finish today.
