Background

Laurie Ibach and Mark Stewart sued their uncle Bruce Stewart, trustee of the Betty L. Stewart Living Trust and the Edward T. Stewart Living Trust, alleging undue influence, breach of trust, and tortious interference with their expected inheritance. The trusts’ amendments, made by Betty Stewart before her 2023 death, had removed Laurie and Mark as beneficiaries in favour of Bruce alone. The Mobile Circuit Court granted summary judgment for Bruce, finding the claims time-barred. Ibach and Stewart appealed to the Alabama Supreme Court, represented by attorney W. Perry Hall.

The appellate briefs Hall filed were, by the Supreme Court’s description, “grossly deficient” — containing “an astounding number of invalid, inaccurate, and irrelevant citations to legal authorities.” The court documented the errors in extensive detail, quoting from Bruce’s appellee brief (which had spent considerable effort cataloguing Hall’s fabrications) and supplementing with its own analysis of the reply brief errors.

The AI Issue

The court documented the specific hallucination errors: Hall cited Ex parte Helms (a will contest case) for a trust-law proposition and provided a quotation from Helms that does not appear anywhere in that opinion — and had also made the same error about Helms before the trial court. Hall repeatedly misquoted real cases, attributed propositions to cases that are entirely unrelated to those propositions, and cited cases for trust-law holdings that the cases do not address. The Supreme Court emphasised that these errors “monopolized an inordinate amount of this Court’s resources” and caused “wasted time and wasted costs to Bruce.” The errors were not marginal or occasional — they were pervasive throughout both the opening and reply briefs.

What the Court Decided

• Appeal dismissed for failure to follow Alabama Rules of Appellate Procedure: the briefs were “grossly deficient” due to the extensive AI hallucinations.
• Sanctions imposed under Rule 38 of the Alabama Rules of Appellate Procedure for conduct “egregious” enough to warrant such action.
• Hall’s conduct referred to the Alabama State Bar.
• Court documented the AI hallucination errors in detail, naming specific fabricated quotations and misrepresented cases, to create a record that the State Bar and other courts could use.
• Appellants’ underlying claims (undue influence, breach of trust, tortious interference with inheritance) were dismissed without reaching their merits.

“Hall, counsel for the plaintiffs, filed briefs in this appeal that contain an astounding number of invalid, inaccurate, and irrelevant citations to legal authorities. That egregious conduct has monopolized an inordinate amount of this Court’s resources and has caused both wasted time and wasted costs to Bruce.”

The India Angle

Indian Law Equivalent

Trust disputes in India are governed by the Indian Trusts Act, 1882, and for family trusts, also by the personal law applicable to the settlor. Disputes involving undue influence over testamentary dispositions are handled under the Indian Succession Act, 1925, or Hindu Succession Act, 1956, depending on personal law. The Supreme Court of India, like the Alabama Supreme Court, exercises appellate jurisdiction with strict requirements for the quality of briefs — advocates appearing before the Supreme Court are expected to cite authorities with complete accuracy, and the Supreme Court has suo motu powers to address professional misconduct by counsel who appear before it.

Bar Council Rules

The BCI’s Rule 49 (no misstatement of law) and Rule 52 (accurate citation) were violated on a large scale in the Ibach case. The Indian Supreme Court and High Courts have inherent power under Articles 129 and 215 to punish contempt, and the Supreme Court Rules 2013 (Order IV) give the court broad authority to regulate the conduct of advocates appearing before it, including striking deficient briefs and referring counsel to the Bar Council. An advocate who filed the equivalent of Hall’s briefs before the Indian Supreme Court would face contempt proceedings in addition to Bar Council disciplinary action.

Practical Advice for Indian Advocates

• The Alabama Supreme Court’s detailed documentation of each AI hallucination error creates a permanent, searchable record of the specific failures — this is now a reference document for courts, bar bodies, and law schools on what AI hallucination errors look like in practice.
• Trust and estate disputes frequently involve complex multi-document factual records (trust instruments, amendments, correspondence, bank records) that AI systems are particularly likely to mischaracterise — verify every citation and every factual assertion about the documents in evidence.
• When the highest court of a state dismisses an appeal for AI-related briefing failures, the clients who lost their appeal because of their counsel’s AI misconduct have a compelling malpractice claim — this is a risk that Indian advocates and their professional indemnity insurers need to account for as AI use increases.

Quick Takeaways

• A state Supreme Court dismissal for AI-hallucinated briefs is the most severe appellate sanction available and represents the complete loss of the appellate right for the aggrieved clients.
• Detailed judicial documentation of specific hallucination errors (specific fabricated quotations, specific misrepresented cases) creates a permanent record that supports both bar disciplinary proceedings and client malpractice claims.
• “Wasted time and wasted costs” to the opposing party are recognised as concrete harms caused by AI-hallucination conduct — courts are willing to compensate these harms through sanctions and cost awards.
