Sydney magistrate Pat O'Shane has escaped conviction despite pleading guilty to drink driving.
The 67-year-old returned a blood alcohol reading of 0.08 when stopped for a random breath test at Linley Point, in March.
A later test conducted at a police station recorded her alcohol content as 0.05 - exactly the legal limit.
The court has heard Ms O’Shane admitted to having three glasses of champagne before getting behind the wheel, but didn’t feel affected by alcohol.
Today she’s been given a 12 month good behaviour bond, with the conviction not being recorded.
She had initially pleaded not guilty to the charge, but changed her plea – she previously had two speeding tickets, which were the only blemishes on her 51 year driving record.
Ms O'Shane's solicitor Andrew Thorpe has told 2GB's Ray Hadley, her good character, together with the low level range helped.
"She's had a series of extraordinary firsts in her life, in terms of her achievements and they are some of things that the court does take into account," he said.
"There will be some people who do not have the sorts of things that will help them [when the court] exercises its discretion and there are some people that do."
