A leading criminal lawyer says there may be significant miscarriages of justice after it was revealed around 1840 false witness statements were made by the Queensland Health Forensic and Scientific Services about the level of DNA detected.

Health Minister Yvette D’Ath revealed the figure in parliament yesterday.

It comes amid the ongoing inquiry into a change of procedure at the lab in 2018, meaning samples were being tested at a different threshold.

Criminal lawyer Bill Potts, the director of Potts Lawyers, said there are a number of things that may happen now.

“It may well be that guilty people that have been found not guilty, it may well be that innocent people have been convicted and in those circumstances and the considerable doubt that’s been placed upon that evidence, it may well be that we see an absolute tsunami of applications to re-open charges, re-open trials,” he told Sofie Formica.

“That is something that the court is going to have to deal with.”
