Citator Basics


Westlaw Logo

KeyCite is Westlaw’s citator. It will help you determine if a source is still good law.

red flagĀ A red flag tells you a case has been overturned on at least one point of law. (e.g., overruled or reversed)

yellow flagyellow flag tells you that your case has negative history but has not been overturned. (e.g., another court has distinguished a holding in the case).

blue-striped flagA blue-striped flag tells you the case has been appealed either to the U.S. Court of Appeals or the U.S. Supreme Court

OverrulingĀ Risk Overruling Risk is an additional feature which will tell you if a case you are citing relies on overturned authority. This is helpful if your case was not directly overturned but an earlier case was, making yours no longer good law. You can learn more here.

 Clicking on the flags or selecting the "negative treatment" tab above the case will take you to a page which explains why the case has been flagged and other related cases.

KeyCite tabs are automatically listed at the top of each case.  The tabs include: filings, negative treatment, history; citing references (with depth of treatment bars) and table of authorities.
