AI-generated lawsuits surge 100x, clogging UK courts with 64,000-case backlog
Curated by the Inblix editorial team
Britain’s employment tribunals are drowning in paper — AI-generated paper, specifically. A new memo from tribunal presidents Barry Clarke and Susan Walker reveals that interim relief applications have exploded a hundredfold, driven largely by workers using ChatGPT and Grok to draft legal claims they’d otherwise pay solicitors to handle. The result isn’t more access to justice. It’s chaos.
Claims rose 39 percent in the year through March 2026, and the backlog swelled 55 percent to 64,000 unresolved cases. Many of these AI-crafted filings stretch hundreds of pages, stuffed with hallucinated case law and demands that bear no resemblance to what tribunals can actually award. The Economist has already branded this a “tragedy of the commons, AI edition,” and the metaphor fits: a shared resource — court time — being depleted by individual actors who don’t bear the full cost of their actions.
The timing couldn’t be worse. Labour’s new Employment Rights Act introduces roughly 25 additional grounds for claims and strips away compensation caps, which will almost certainly accelerate the filing frenzy. Employers are getting squeezed from both sides, paying solicitors to swat away nonsense claims while legitimate cases from workers with real grievances sit in the queue behind AI-generated doorstops. This isn’t a UK-only headache, either. One US federal judge has already called AI-generated lawsuits an “existential threat to the federal courts.”
There is a counter-narrative worth watching. A study out of Pakistan found that when judges were given AI tools and proper training, they processed more cases faster. That suggests the problem isn’t AI in the courtroom per se — it’s asymmetric adoption. When one side automates filing and the other side is stuck with manual review, the system breaks. Britain’s tribunals weren’t designed for a world where anyone with a free chatbot can generate litigation at zero marginal cost. They’re about to find out what that world costs everyone else.
💡 Key Takeaways
- AI-generated employment claims have caused interim relief applications in UK tribunals to surge a hundredfold, with filings often containing fabricated laws and unrealistically high demands.
- The case backlog jumped 55 percent to 64,000 in the year through March 2026, while overall claims rose 39 percent, delaying justice for workers with legitimate grievances.
- Labour's new Employment Rights Act is expected to worsen the crisis by adding roughly 25 new claim grounds and removing compensation caps.
- A Pakistan study suggests the outcome flips when judges also get AI tools and training, pointing to asymmetric adoption as the core problem rather than AI itself.
