A Launceston woman who smashed a stubby on the face of her partner's sister has pleaded not guilty to wounding.
Renee Joy Payne appeared for trial in Launceston's Supreme Court today.
The court heard the incident occurred at a gathering of the alleged victim's family on October 6 2012 in Prospect.
The alleged victim said she was hit with the bottle over the right eye after telling Ms Payne off for comments she made about her mother.
However defence counsel Greg Richardson told the jury self defence was a ``live issue'' as well as whether Ms Payne consciously hit her with the stubby.
During cross-examination of the alleged victim he suggested the former boxer had thrown shadow punches at his client which she rejected.
``I want to suggest to you said ``if I find out you've said something look out,'' he said.
``No,'' she replied.
Mr Richardson the woman had recorded a blood alcohol level of 0.224 at Launceston General Hospital where she was treated.
The trial is expected to run for two days.
