But your case law research does not end simply because you've found an appellate court case that appears to support your argument. Even a case directly on point may lose its authority if
You can verify case citations using KeyCite (the citation research service from <% Response.Write Application("strCompanyName") %>-available only on Westlaw®). To automatically check your citations in the citator services on Westlaw, use Westcheck® 4.0 or higher.
KeyCite is the citation research service from West that integrates all case law on Westlaw. With KeyCite, you can determine if your case is good law and find other cases and secondary sources that cite your case. KeyCite is available only on Westlaw, which can be accessed through WestMate® software or on the World Wide Web at lawschool.westlaw.com. (You can also access Westlaw from The West Education Network (TWEN).) KeyCite is as current and comprehensive as Westlaw.
If you can access Westlaw, you can access KeyCite using one of the following methods:
A red flag warns that the case is no longer good law for at least one of the points it contains.
A yellow flag warns that the case has history but hasn't been reversed or overruled.
A blue "H" indicates that the case has some history.Depth of Treatment Categories
KEYCITE: DISPLAYING THE HISTORY OF THE CASE
When you first access KeyCite, the history of the case is displayed. The history is divided into the following categories:
Direct History traces the same case through the appellate process and includes prior and subsequent history.
Negative Indirect History lists cases outside the direct appellate line that may have a negative impact on the precedential value of your case.
Related References lists cases that involve the same parties and facts as your case, whether or not the legal issues are the same.
KEYCITE: DISPLAYING CITATIONS TO THE CASE
To retrieve citing references for your case, click Citations to the Case. A list of all cases on Westlaw and secondary sources, such as law review articles and ALR® annotations that cite your case is displayed.
You will find cases in your research that have been cited by hundreds, sometimes thousands, of cases and secondary sources. Fortunately, the following KeyCite features can make a long citations list more manageable:
Use KeyCite to see if your statute is still good law and retrieve other documents that cite your statute. KeyCite gives you the history of a statute and includes case citations, administrative materials and secondary sources that have cited a statute. You can also use KeyCite to locate pending legislation.
VIEWING THE HISTORY OF A STATUTE
To view historical information for a statute, type the statute citation in the KeyCite a citation text box and click GO. Click the History tab to view the complete history of your statute. The information contained in the Credits and Historical and Statutory Notes can assist you in determining whether the section you check in KeyCite has been amended or repealed.
