Tippecanoe County Assessor v. Craig Goergen
Indiana Tax Court · Oct 17, 2025
What happened in this matter?
The Indiana Tax Court issued a formal admonishment to a pro se litigant for citing a fictitious case likely generated by AI. The Court ruled that the litigant, a non-attorney, could not represent his office and ordered him to retain counsel, while warning that failure to verify AI-generated research undermines judicial integrity.
- Why the court cared
- The Court reasoned that the petitioner's citation of a non-existent case wasted judicial resources and hindered the administration of justice. It noted that judges must rely on the authenticity of cited authorities to make just decisions and that litigants have an affirmative duty to verify the accuracy of all sources.
- Why it matters now
- This case illustrates the risks of pro se litigants using AI for legal research without verification. It reinforces the judicial expectation that all parties, regardless of representation status, are responsible for the authenticity of their cited authorities.
Why this matter is tracked
In an appeal before the Indiana Tax Court, pro se petitioner Eric Grossman, the Tippecanoe County Assessor, attempted to represent his office without counsel. During the proceedings, Grossman submitted a brief containing a citation to a non-existent case, 'Hamilton Cnty. Assessor v. Allisonville Rd. P’ship, 170 N.E.3d 1117 (Ind. Tax Ct. 2021).' The Court determined the citation was likely the result of a generative AI hallucination. The Court admonished Grossman for the use of fictitious authority, emphasizing the duty of litigants to independently verify all research. The Court ultimately ordered the petitioner to retain licensed counsel by November 17, 2025, or face potential dismissal of the appeal for procedural defects.
This case illustrates the risks of pro se litigants using AI for legal research without verification. It reinforces the judicial expectation that all parties, regardless of representation status, are responsible for the authenticity of their cited authorities.
