I have noted the steps taken to ensure that there is no repetition but considered that it was necessary to set out what had taken place in this judgment given the serious consequences that an error of this nature might have had in other circumstances. It would be naive to assume that there will not be an increasing use of artificial intelligence in legal work in future; indeed, that may be both necessary and beneficial. The episode highlights the risks of its use without appropriate oversight particularly for legal research.”
