What is the purpose of filtering results after Shepardizing a case?

Filtering results after Shepardizing a case is primarily aimed at limiting the search results to specific jurisdictions and ensuring the relevance of the cases identified. The process of Shepardizing a case involves checking the case's subsequent history and judicial treatment to ensure that legal research reflects current law and interpretations pertinent to a specific jurisdiction. By filtering the results, a legal researcher can focus on the most relevant precedents and decisions that will apply to the specific legal issue or jurisdiction they are working within. This allows for a more efficient and targeted research process, ensuring that the citations and cases reviewed are not only valid but also applicable to the legal context being studied.
