A new research paper introduces a method to audit citation-context retrieval systems for legal precedent, addressing the issue of temporal leakage. The proposed temporal-admission decomposition quantifies how much of a retrieval system's performance gain is due to using future information unavailable at deployment. The study demonstrates that unfenced methods can significantly overstate their effectiveness, with a substantial portion of the gains attributed to future citations rather than genuine retrieval capabilities.
