A couple who were tasered by police in November 2008 will receive $1.1 million in compensation despite continuing legal action against them, the WA Attorney-General has promised.

A spokeswoman for John Quigley has confirmed to the ABC the Attorney-General's recent statements in parliament were an assurance the government would be granting them the compensation.

"When that finding came out with a $1.1 million damages award that the taxpayers will ultimately have to pick up – I note it is under appeal, but the taxpayers are obviously going to have to foot the bill – the Police Department's response on that occasion was that those people had been fully investigated and that, despite the judge's findings against them, had been cleared," Mr Quigley said.

It follows a ruling by District Court Judge Felicity Davis in December 2016 granting Robert Cunningham and Catherine Atoms more than $1.1 million in compensation – a decision which was subsequently appealed by the WA government.

Justice Davis is expected to hear the case in the WA Supreme Court of Appeal next month, however Mr Quigley's statement appears to suggest the government may not pursue the appeal.

Ms Cunningham and Ms Atoms have accrued legal fees and medical bills amounting to hundreds of thousands following the tasering incident, which has left them with post-traumatic stress disorder and physical injuries.

The compensation granted was expected to be paid by both the WA Government and three police officers involved, however court documents suggest the officers lack the financial resources to cover the cost.

The WA Government's appeal is based on the suggestion the officers acted maliciously, therefore making them personally culpable, according to section 137 of the Police Act.

It comes in the wake of a finding by the state's corruption watchdog that the tasering of another man during a random breath test in March 2017 was "for no good reason".

An initial police review of the incident cleared the officer's actions, but it will now be investigated by Internal Affairs in light of the CCC findings.

"We're going to look at this matter from end-to-end and confirm what we've done ... and at the end of the day try and work out why we have two different outcomes," Assistant Police Commissioner Nick Anticich told 6PR radio on Thursday.

Video of the incident, captured by a passenger in the car during a traffic stop, shows the passenger arguing with police that the driver was not at fault for flashing his car's lights.

Moments later an officer fires a taser into the car and a woman can be heard screaming.

In its report handed down on Wednesday, the CCC said the officer had no lawful jurisdiction to taser the man and found his actions were unreasonable and oppressive.
