The Nebraska Supreme Court has suspended Omaha attorney Greg Lake from practicing law until further notice after he admitted to using artificial intelligence to write a legal brief and then initially denying it to the court.

Why it matters

This case raises ethical concerns about the use of AI in the legal profession, as attorneys have a duty of candor to the court and must ensure the accuracy and integrity of the documents they file. The suspension highlights the potential consequences for lawyers who fail to be transparent about their use of AI technology.

The details

In February, Lake argued an appeal in a divorce case before the Nebraska Supreme Court, but the justices noticed numerous errors in the brief he had filed. When pressed about the fictitious cases and misquotes, Lake initially denied using AI, but later sent an affidavit admitting to using AI to write the brief, calling it a 'grave error of judgment' for failing to be forthright with the court.
