Her husband, former New Zealand cricketing great Glenn Turner, alleges Dame Sukhi "had to endure a drawn-out inconvenient piece of police incompetence that finally led to a no-show on their side".
"You start to lose faith in the enforcement people if that's the way they're going to behave."
Police say: "The individual in this case accepted responsibility and took diversion."
Dame Sukhi's defence statement, which she didn't have to give in court, says she was stopped by Queenstown senior sergeant Jon Bisset north of Cardrona on February 21.
A driver, who'd phoned *555, claimed she repeatedly crossed the centre-line.
She said Bisset repeatedly questioned her, despite admitting he had no proof. "We have to look after our people," he reportedly told her.
Dame Sukhi - who, to get diversion, admitted failing to drive in her lane - said she overtook one vehicle on a straight stretch of road.
"He then asked me if I had had a hard day."
Finally, she said Bisset told her he'd send her a $150 infringement ticket.
"As he walked off, he said that I had been breaching the centre-line 30 times.
"I was disturbed by his decision and the alacrity at the presumption of guilt."
Dame Sukhi believes that, beyond checking she hadn't been drinking, Bisset, under the police's *555 protocol, should have done no more than issue a warning.
In follow-up disclosure documents, Dame Sukhi said she learnt for the first time that the complainant had contacted cops because her vehicle was allegedly "on wrong side of road going around blind corner".
An adjudicator in Wellington's police infringement bureau added the words - "with a vehicle travelling towards you".
She comments: "The latest accusation is extremely serious, one which I found outrageously unbelievable."
India-born Dame Sukhi said she has had a "first-class driving record" during her 43 years in New Zealand, including nine years driving a Dunedin mayoral vehicle. During 12 years living in Wanaka, she estimated she had driven the Crown Range Rd more than 100 times.
"I cannot believe that any policy under the *555 regime would put the fate of a driver in the hands of Joe Public."
Especially, she said, when that "Joe Public" got so many basic facts wrong: he said she had two passengers - she had no one; he said he left Queenstown about 6.30pm, but she was stopped just past Cardrona only 20 minutes later; he couldn't recall the colour of her car, beyond saying it was "light"; he couldn't recall the model of the car despite "a very large Mazda logo attached to the rear" and having allegedly followed her along distance.
Turner added they were upset "we went to great lengths to try and get some sense out of the police", but to no avail.
"It seems that if the officer who books someone wants to proceed with the charge, his so-called superiors automatically go along with his wish."
Asked to address the Turners' complaint, Bisset - who recently relocated to Invercargill - yesterday emailed a general statement.
"Police actively encourage people to use the *555 service to report any concerning driver behaviour," he said.
"Anything which deters drivers from endangering themselves or others is a positive thing."
Bisset said any complaint is "fully considered" before action is taken.
