The Shepard's Signal indicators
The Shepard's Signal indicators are integrated into case law documents and provide an immediate indication of the subsequent history and treatment of a particular case. When these codes are present, Nexis Uni® displays one of these signals.
When a signal is generated from the Subsequent Appellate History, the system looks at the Subsequent Appellate History as a chain of interconnected events. Thus, the phrase generating the signal may be assigned to a decision in that chain that does not apply directly to your case, but may be several links in the chain away from your case.
