[Financial News] A non-lawyer has reportedly won a civil and criminal dispute against a lawyer by submitting briefs written with the help of artificial intelligence (AI).
According to YTN (Yonhap Television News) on the 18th, Park Jang-ho, who had hired lawyer A, ended up terminating the contract after a conflict over the drafting of a written opinion.
What followed was an unexpected legal battle. The law firm he belonged to filed a civil suit, demanding an additional 5.1 million won in unpaid legal fees, and Lawyer A also filed a criminal complaint, claiming that Park's manner of protest amounted to threats.
Park told the media, "I went there to resolve the case quickly, but this lawyer ended up creating two more cases," adding that he felt "an enormous sense of betrayal and injustice."
Park looked into hiring a lawyer twice for the lawsuit, but both declined the case, saying it would be burdensome to take on the same lawyer.
In the end, Park prepared the case on his own, and the result was surprising. Police found no grounds for the criminal allegation and decided not to send the case to prosecutors, while Park also won the civil suit in the end.
The weapon Park used was artificial intelligence. It handled everything from analyzing the complex complaint and reviewing the legal issues to drafting various documents. It also generated tailored response strategies in real time simply by entering the complaint.
In particular, the AI found a transcript with the wrong date in the opinion letter written by Lawyer A and also detected missing dates and signatures in the contract.
Park said, "I used to think a lawyer was absolutely indispensable when it came to solving legal problems, but maybe that is no longer the case. I felt really amazed, thinking, 'I actually beat a lawyer myself.'"
