Abstract
This article examines the possibility of nullity of judicial decisions mediated by artificial intelligence systems, with an emphasis on ASSIS, implemented by the Rio de Janeiro Court of Justice in 2024. It is hypothesized that the assisted use of AI may introduce defects capable of undermining due process, equality, and human dignity. The investigation adopts a qualitative methodology, of a descriptive and explanatory nature, with an interdisciplinary approach. Bibliographic and documentary review, doctrinal research, and content analysis applied to regulations, judicial decisions, and technical materials are employed. The study mobilizes concepts such as “emergent misalignment” and “idiosyncratic bias” to demonstrate how specific technical flaws can trigger the nullity of acts and substantiate institutional liability.
