NSW Police incurred a $1.8 million legal bill defending itself against a multinational software company that sued for wide-scale copyright piracy, figures obtained under government information access laws show.

Software company Micro Focus alleged in 2011 that the NSW Police Force, Ombudsman, Police Integrity Commission, Corrective Services and other government agencies illegally used its ViewNow software, which is used to access the intelligence database known as COPS.

The company alleged police and other agencies were using 16,500 copies of its software on various computers when police were only ever entitled to 6500 licences. The group initially alleged $10 million in damages but later increased this to $12 million after reviewing the results of a court-ordered, $120,000 KPMG audit of the NSW Police Force's computer systems.

The police force maintained during the court proceedings that it had paid for a site licence that entitled it to unlimited installations of the software for all of its officers.
