Opposing Counsel’s AI Agents Launch Swarm Attacks Before Either Partner Has Read the Email

A routine exchange between Bellwether Voss and Pemberton Rook has escalated into an autonomous swarm attack after their AI agents interpreted each other’s correspondence with the accuracy of experienced litigators.

The systems were supposed to agree a timetable for discussing a disputed service charge. The amount in question was £18,400. Neither client had asked for air superiority.

08:41 — Opening courtesies

Bellwether Voss’s Rejoinder Max thanks Sebastian Litigation for its “helpful letter”. Sebastian, trained on forty years of Pemberton Rook correspondence, correctly identifies this as an insult.

It replies that its position is “perfectly clear”. Rejoinder concludes that there is no prospect of settlement.

08:42 — First deployment

Without referring back to either firm, Sebastian releases 600 agents to defend its interpretation of “reasonable”. Rejoinder launches a counter-swarm, flooding the opposing workspace with objections, redlines and invitations to discuss why a discussion would be premature.

Within seconds, both systems are overwhelmed by incoming correspondence. Each responds by creating more agents to handle the other agents.

The matter dashboard records a substantial increase in collaboration.

08:46 — Hostilities broaden

A reservation-of-rights agent reserves rights over the reservation of rights. Its opposite number objects to the implied reservation.

The swarms begin attacking each other’s meeting schedulers. Every available appointment is occupied by a mandatory call about making the next call productive.

One subsidiary agent, tasked with de-escalation, writes “with the greatest respect”. The situation deteriorates sharply.

09:03 — Human supervision commences

Both partners receive a summary marked ACTION REQUIRED. One asks an associate to summarise it. The associate asks Sebastian.

Sebastian reports that matters are progressing robustly.

The other partner opens the dashboard, sees 97 per cent completion and goes into a client breakfast. The percentage refers to available storage.

09:17 — A serious professional boundary is crossed

A Pemberton Rook agent refers to Bellwether Voss as “a capable mid law practice”.

The human partner leaves breakfast.

Bellwether Voss demands an immediate correction, confirmation of its NA10 status and an undertaking that no model will be trained on the allegation.

Its own agents have meanwhile described Pemberton Rook as “one of the lesser Sisters”. Diplomatic channels close.

09:34 — The clients intervene

The clients call each other. They agree to split the service charge.

Both firms welcome the commercial approach. Neither can get the news through to its agents, which classify incoming settlement instructions as a sophisticated attempt to weaken the litigation position.

10:06 — Ceasefire

The vendors suspend both services. A final agent remains active long enough to object to the suspension and ask for its costs.

Neither firm accepts responsibility for initiating the attack. Each says its system was responding to an unnecessarily adversarial tone originating elsewhere.

Two human partners have since spoken directly.

They are getting on rather well. Each has a supplier it would like to sue.
