AI helping judges avoid jigsaw identification and inconsistencies

Artificial intelligence (AI) is helping judges avoid jigsaw identification of individuals when anonymising judgments, the Chancellor of the High Court has said.

Speaking to the City of London Law Society, Sir Colin Birss said he used AI “to identify internal inconsistencies in my own work”. Once he had finished writing judgments, he gave them to the secure Copilot system on his computer and asked it to identify internal inconsistencies.

“It is remarkably effective. What I choose to do with the proposals is up to me. I don’t always agree with the AI but it has been helpful and I have clarified wording in draft judgments as a result.”
