How to Use This Page

Entries are dated and categorized. Each supplements the book rather than replacing its framework. The four-factor evaluation, the tier system, and the verification protocol remain the method. New developments are applied through that method, not around it.

Attorneys implementing the governance policy in Appendix A should review this page at their scheduled policy review date and flag any entry that affects their practice.

Sanctions & Workflow April 2026

Sullivan & Cromwell acknowledges roughly 40 inaccurate citations in In re Prince Global Holdings Limited

On April 18, 2026, a co-head of Sullivan & Cromwell’s global restructuring group wrote to Chief Judge Martin Glenn of the U.S. Bankruptcy Court for the Southern District of New York acknowledging AI hallucinations and manual errors in an emergency Chapter 15 motion. The firm’s letter confirmed it had mandatory AI training, a firmwide verification standard, and a separate citation review policy. All three failed on the same filing.

Supplements: Chapter One (documented sanctions record), Chapter Six (verification protocol), Appendix B (incident response framework). The case illustrates the distinction drawn throughout the book between firm-level governance and matter-level workflow documentation.
