Evidence stage
ConstraintFailure, rollback, regulation or cost is suppressing adoption. Can lower an assessment or widen its uncertainty.
Tasks this bears on
Checking what the tools produced
Confirming that a cited case exists, that a summary matches the source, that a generated clause does not contradict another.
New task✓ Evidence-backed
Where this applies
US federal court (S.D.N.Y., Judge Castel). The sanction rested on failing to verify and on standing by the citations once challenged. Widely cited in later professional-conduct guidance.
What this means
A constraint record that creates the linked task: a federal court fined lawyers $5,000 not for using ChatGPT but for filing six invented cases without checking, and standing by them once challenged. On the deployment layer it fixes where the tools may be used in litigation — only with someone confirming every citation exists — and that confirming step is the 'checking what the tools produced' work now landing on paralegals.
What it does not yet show
One sanction order in one US district says nothing about how firms pay for verification: whether it becomes a billable paralegal skill or unpaid diligence is a firm-by-firm decision the opinion does not touch. It does not show fabricated citations are common, only that the cost of one slipping through is now on record — and it applies to court filings, not to contract or research work.
What you can check
Ask your supervising attorney whether the firm has a written rule on who verifies citations in machine-assisted drafts and whether that time is recorded to a matter code; no rule means the task exists but has not been assigned, and non-billable time means it has been assigned to you for free.
Does it change the assessment?
No. The impact index is never moved by a single event. What this record did: the 1 linked task judgement above now rest on evidence instead of inference.
