The police have confirmed no review will take place - after it was revealed more than 100 officers are under investigation for falsifying 30,000 tests.
The falsified records were only discovered after police built a new algorithm to analyse the data, as the devices themselves cannot distinguish between legitimate and illegitimate tests.
Acting Deputy Police Commissioner Jill Rogers says it's unclear what will come out of the employment investigation.
"They'll have their own individual investigations now to work through to work out why they did it. I scratch my head, going - what on earth were they thinking? It appears many of them were done on the way from or to legitimate checkpoints."
