What does a red stop sign in Shepard's indicate?

The red stop sign in Shepard's indicates that the case is under scrutiny or potentially bad law. This visual cue signals to legal researchers that there may be issues with the case's validity, such as subsequent court decisions that have questioned or criticized it, or possible overruling. It serves as a warning to take extra caution when relying on the legal principles established in that case, prompting further investigation into its current status before using it as authority in legal arguments or proceedings. In contrast, a case indicated with a different color may suggest that it is good law, leading authority, or has been recently affirmed, but the red stop sign specifically signifies concern about the integrity and applicability of the legal precedents set forth by that case.
