Judge's 'Dynamite Charge' to Break Jury Deadlock
4 Sep
Summary
- A 'dynamite charge' is a judicial instruction to overcome jury deadlock.
- Massachusetts uses Tuey-Rodriguez instructions, known nationally as Allen Charge.
- A similar instruction failed to produce a verdict in the Karen Read trial.

When a jury reaches an impasse, a judge may deliver a special set of instructions designed to break the deadlock and prevent a mistrial. In Massachusetts, these instructions are referred to as the Tuey-Rodriguez charge, and they are recognized nationwide as an Allen Charge.
These instructions prompt jurors to consider the validity of their own viewpoints and those of their fellow jurors, encouraging continued deliberation toward a unanimous verdict.
The effectiveness of such measures was recently tested. In the 2024 murder trial of Karen Read, the judge utilized the Tuey-Rodriguez instructions when the jury became deadlocked. Despite further deliberation, the jury could not reach a consensus, leading the judge to declare a mistrial.
