The Consequence Library · How records are made and graded
The Commission of Inquiry into Forensic DNA Testing in Queensland, conducted by Commissioner Walter Sofronoff KC and reporting in December 2022, examined automated processing at Queensland Health Forensic and Scientific Services. An automated quantitation threshold determined which samples were recorded as containing insufficient DNA for further processing. It was applied, and later extended from volume crime to major crime, in circumstances where the inquiry did not find evidence of proper authorisation. Roughly 30,000 cases required review.
Evidence caveat. No AI system was involved. The record is included because an automated parameter with case-level consequences changed scope without a locatable authorisation record, and because the inquiry spent years reconstructing what a contemporaneous signed decision record would have shown directly.
What happened
Queensland Health Forensic and Scientific Services used an automated quantitation threshold under which samples below a set DNA concentration were recorded as "DNA Insufficient for Further Processing" and not taken forward. The Commission of Inquiry documented that the threshold was applied, and subsequently extended from volume crime samples to major crime samples, despite the laboratory's own validation data indicating that interpretable profiles were obtainable below it, and without evidence before the inquiry of proper authorisation or consultation. Separately, the inquiry documented an automated software function that increased the volume of low-quantity DNA samples, including positive control samples, with the effect that outputs appeared normal where extractions had been systematically poor. Roughly 30,000 cases required review and prosecutions were affected. The inquiry reconstructed the decision history from procedure versions, correspondence and witness evidence over an extended public hearing programme.
Where control failed
Two control states are documented. First, an automated threshold determined case outcomes and its extension to a more serious category of casework was not shown to the inquiry to have been properly authorised. Second, an automated function altered sample handling in a way that produced normal-looking output from abnormal input, so the human review downstream received results that did not reveal the underlying condition.
The authority question
The inquiry's difficulty was not establishing what the automation did but establishing under whose authority its scope changed. A parameter with case-level consequences was extended into major crime, and the authorisation for that extension was not established on the evidence before the inquiry.
What could be proven afterward
The Commission of Inquiry produced a substantial public evidentiary record, including transcripts and exhibits. It was assembled retrospectively from procedure versions, correspondence and testimony over a period of years. The second finding is the sharper one for this library: automation that normalises its own abnormal inputs removes the signal human reviewers depend on, so the review can be genuine and still be uninformative.
Control state, before and after
Before the consequence
An automated threshold governing case progression, extended in scope without an authorisation record the inquiry could locate. An automated sample-handling function whose effect on control samples was not surfaced to reviewers.
After the consequence
Commission of Inquiry reported December 2022. Roughly 30,000 cases required review, with consequences for affected prosecutions.

This record describes what sources establish about a consequence and the control state around it. It separates confirmed fact from source-stated cause and from architectural analysis, and it makes no claim that any control or product would have prevented the outcome. Gap codes identify a failure class, not a remedy.
