The UK Judicial Office has issued guidance allowing judges in England and Wales to use OpenAI's ChatGPT for writing rulings. The document outlines potential security and legal issues, such as maintaining confidentiality, ensuring accuracy, and preventing bias. The guidance suggests that while AI can be useful for tasks like summarizing text and automating tasks, it may not handle complex legal language well and should not be used for reasoning or comparisons. The judiciary's adoption of AI is cautious due to past incidents where AI, specifically ChatGPT backed by Microsoft Corp. (NASDAQ:MSFT), created fictitious cases.
