ACL Statement on Desk Rejecting Papers with Hallucinated References
"During the final consistency checks of the camera ready versions of papers accepted to ACL 2026, we identified over 100 papers that contained citations to non-existent literature. Since these papers were going to be published and are no longer subject to the anonymity requirements, an automated system was used to identify potential citation issues and then all flagged citations were reviewed by human experts (PCs and SACs) to confirm that references did not exist. Whether human-authored or LLM-generated, the inclusion of these non-existent references is a clear violation of the ACL Policy on Publication Ethics. Consequently, we have made the decision to desk- reject these accepted papers to maintain the quality and trustworthiness of the conference proceedings."
