Editor Notes: The declaration of Ivana Dukanovic related to ECF no. 365 can be read here: https://s3.documentcloud.org/documents/25943457/anthropic-515-filing.pdf. This incident record includes the names of the attorneys who submitted a court filing containing erroneous citations attributed to generative AI use. Their names are drawn directly from the public docket of Concord Music Group, Inc. et al. v. Anthropic PBC. Inclusion here reflects their formal authorship of the document in question. The declaration submitted by Dukanovic acknowledges the citation errors and describes the circumstances of their introduction. That statement is an early example of what may become a new genre of legal apology shaped by AI-assisted work. This record aims to document how such tools are being integrated (sometimes uneasily) into professional and institutional practice.
