Shepard's Citations

Shepard's Citations

The Shepard's Citations Service provides a comprehensive case citation and treatment history to verify the validity of case law, statutes, agency opinions, and other legal documents. Only case law is covered in LexisNexis Academic.

Shepardizing™ is the practice of using the Shepard's Citations Service to validate a citation.

When you Shepardize® a case, LexisNexis provides a report showing every opinion where that case has been referenced, all treatments of the case, and, most importantly, whether or not the case is "good law." If the case has been overruled, it is considered "bad law" and may no longer be cited as a legal precedent.

Using the Shepard's® Citations Service in LexisNexis Academic to find out the status of a case.
