Thomas v. Commissioner of Internal Revenue
US Tax Court · Oct 23, 2024
What happened in this matter?
The US Tax Court struck the petitioner's Pretrial Memorandum as a sanction for violating Rule 33, which requires counsel to certify that filings are grounded in fact and law. The court found the document contained multiple non-existent or misattributed case citations, likely resulting from AI-assisted drafting that went unverified by the signing attorney.
- Why the court cared
- The court reasoned that under Rule 33, the signing attorney is responsible for the content of pleadings. Because the counsel failed to review the paralegal-prepared memorandum, she failed to certify that the citations were accurate. The court deemed the memorandum stricken as a symbolic sanction, noting that the substantive legal arguments were otherwise correct and that imposing a pecuniary cost would be inappropriate given the client's economic status and the counsel's role in providing necessary representation.
- Why it matters now
- Partners must personally read paralegal-prepared memos before signing — delegation is not a defense when citations are wrong.
Why this matter is tracked
Misrepresented: Case Law | Cited Schluter v. Commissioner, T.C. Memo 1998-269, for deductibility of unreimbursed employee expenses; Court found Schluter is T.C. Memo 1970-67 (dependency exemption) and T.C. Memo 1998-269 is Schmitt v. Commissioner (method of accounting), neither supporting the proposition. Outcome: Pretrial Memorandum stricken. The lawyer for the petitioner admitted to not reviewing the memorandum, which was prepared by a paralegal. The court deemed the Pretrial Memorandum stricken but did not impose a monetary penalty, considering the economic situation of the petitioner and the lawyer's service to a client who might otherwise be unrepresented. It was also pertinent that the law being stated was accurate (even if the citations were wrong).
