A lawyer who has admitted to using false quotes created in a continuing legal battle with music publishers by the Claude AI chatbot of humanity, according to a filing made in a Northern California court on Thursday.
Claude hallucinated the quote with “inaccurate titles and inaccurate authors.” Humanity’s lawyers explain that their “manual citation check” did not catch it or that several other errors caused by Claude’s hallucination.
Humanity apologised for this error, calling it “an honest quoting error, not an authority production.”
Earlier this week, lawyers representing Universal Music Group and other music publishers accused the human expert witness (Olivia Chen, one of the company’s employees) of using Claude to cite fake articles in her testimony. Federal judge Susan Van Karen subsequently ordered humanity to respond to these allegations.
The Music Publishing Company’s litigation is one of several disputes between copyright holders and high-tech companies over the misuse of their jobs to create generative AI tools.
This is the latest example of lawyers who use AI in court and regret decisions. Earlier this week, a California judge accused a pair of law firms of submitting “fake generation studies” in his court. In January, an Australian lawyer was caught using ChatGpt in preparing court documents, and the chatbot produced a false quote.
However, these errors have not stopped startups from bringing up big rounds to automate their legal work. Harvey, which uses a generator AI model to support lawyers, is in discussions to raise more than $250 million at a $5 billion valuation.
