Westlaw's KeyCite citator will indicate if a legal decision is in part or whole is still valid using a flag system. You can also view the history, negative treatment, and citing references for the case in question. KeyCite uses the same system for statutes and regulations.
Under Citing references, select cases to find newer cases that have cited the law you are searching for. You can narrow searches more using filters like jurisdiction, depth of treatment, and head notes of legal issues, or by searching within the results by keyword.
Westlaw uses their Key Number indexing system to organize cases by legal topics. You can browse the list or search within the subject headings for your topic. Select the "i" next to the heading to see the scope of the term and what is not included. Click the subject heading link to see the term's subheadings.
