ChatGPT may be smart enough to pass the bar exam, but lawyers should take caution before relying on the Artificial Intelligence (“AI”) platform to conduct any legal business.

On June 22, 2023, Judge P. Kevin Castel of the Southern District of New York released a lengthy order sanctioning two attorneys for submitting a brief drafted by ChatGPT. Judge Castel reprimanded the attorneys, explaining that while “there is nothing inherently improper about using a reliable artificial intelligence tool for assistance,” the attorneys “abandoned their responsibilities” by submitting a brief littered with fake judicial opinions, quotes and citations.

After a bit of hiatus on aggressively challenging vertical mergers, regulators both here in the United States and abroad have resumed initiated actions to challenge vertical mergers. Traditionally a difficult lift for the FTC, vertical vergers involve companies above and below each other in the supply chain. Instead of directly competing, an upstream company acquires the company it supplies with critical inputs. Recent announcements of high-profile vertical mergers signal increased FTC and European regulatory scrutiny in the area.

Under the Clayton Act (15 U.S.  Code § 18), certain business acquisitions are prohibited where “the effect of such acquisition may be substantially to lessen competition, or to tend to create a monopoly.” Long-standing jurisprudence has established that merger challenges require, at the outset, a prima facie showing of the likelihood of a substantial lessoning of competition that would result from the merger or acquisition.  Such prima facie showing typically takes the form of claims and evidence related to market shares above a certain level, but can take other forms.
