The Supreme Court has ordered a Brisbane towing entrepreneur to hand over confidential personal records given to his company by the Queensland Police Service and to destroy his own copies.

The Queensland Government applied for an urgent hearing to prevent Dominic Holland from disclosing the confidential records after the tow.com.au chief executive told the ABC he might be forced to sell what he called "critically sensitive" details of more than 21,000 Queenslanders if he sold his towing business.

Mr Holland has been embroiled in a multi-million-dollar dispute with the State Government.

Earlier this week, he told the ABC he felt he had no choice other than sell his share in the towing firm because the Government terminated his contract to tow and impound cars under anti-hoon laws.

Mr Holland had said the Queensland Police Service had provided his business with personal records ranging from drivers licence details to bank accounts.

The ABC has sighted some of the records, which include bank accounts, drivers licences and contact details of residents, password encryption details, as well as payroll numbers of police officers.

Late on Thursday afternoon, the Queensland Supreme Court heard Mr Holland gained many financial records from individuals and not the police.

Justice Roslyn Atkinson ordered Mr Holland return all data provided by police and to destroy his own copies of the data by June 21.

Justice Atkinson said this was a requirement under the company's agreement with the State Government.

"Far from delivering to the state all the documents and other material containing, recording or referring to confidential information, that confidential information has been retained and used by the service provider," Justice Atkinson said.

"It would appear that unless ordered to, the respondents had no intention of complying with that provision of the deed, and instead the respondents had control of sensitive confidential information which belongs to the state which it appears they intend to use and or sell as an asset of the business.

"That cannot be allowed to happen."

But Justice Atkinson made no ruling on other personal information that tow.com.au had collected while operating under the State Government contract.

Representing himself in court, Mr Holland said he had not divulged any of the information.

"Can I say that neither myself or any employee of tow.com.au has breached any privacy obligations at all or released any … private information of individuals in any way to any person … since the beginning of this contract," he said.

Mr Holland could face arrest if he does not return and delete the information.
