From People v. Crabill, released yes،ay:
The Presiding Disciplinary Judge approved the parties’ stipulation to discipline and suspended Zachariah C. Crabill (attorney registration number 56783) for one year and one day, with ninety days to be served and the remainder to be stayed upon Crabill’s successful completion of a two-year period of probation, with conditions. The suspension took effect November 22, 2023.
In April 2023, a client hired Crabill to prepare a motion to set aside judgment in the client’s civil case. Crabill, w، had never drafted such a motion before working on his client’s matter, cited case law that he found through the artificial intelligence platform, ChatGPT. Crabill did not read the cases he found through ChatGPT or otherwise attempt to verify that the citations were accurate. In May 2023, Crabill filed the motion with the presiding court.
Before a hearing on the motion, Crabill discovered that the cases from ChatGPT were either incorrect or fic،ious. But Crabill did not alert the court to the sham cases at the hearing. Nor did he withdraw the motion. When the judge expressed concerns about the accu، of the cases, Crabill falsely attributed the mistakes to a legal intern. Six days after the hearing, Crabill filed an affidavit with the court, explaining that he used ChatGPT when he drafted the motion.
Through this conduct, Crabill violated Colo. RPC 1.1 (a lawyer must competently represent a client); Colo. RPC 1.3 (a lawyer must act with reasonable diligence and promptness when representing a client); Colo. RPC 3.3(a)(1) (a lawyer must not knowingly make a false statement of material fact or law to a tribunal); and Colo. RPC 8.4(c) (it is professional misconduct for a lawyer to engage in conduct involving dis،nesty, fraud, deceit, or misrepresentation).
The case file is public per C.R.C.P. 242.41(a).
