KeyCite Signals (Analysis):
Each document is assigned a signal to make it easy to identify a document’s status. These signals appear in the top left of the document, next to the case citation or the statute citation.
The signals are defined as follows:
|The document is no longer good for at least one point of law.
|Some negative treatment but not overruled or reversed; proposed legislation
|Document has been appealed to the U.S. Court of Appeals or the U.S. Supreme Court
When you see a red flag, follow this procedure:
This will take you the part of the case that cites to the case you wish to cite. Read through what the case says about your case, noting whether the case cites to the page number and/or headnote you wish to cite in your case.
Determine what the case says about your case: does the case overturn, negatively impact, distinguish, etc. your case. If the case overturns the part of your case that you wish to cite, then you cannot cite to your case for that point of law.
Across the top of a case, you will see the following tabs:
Across the top of a statute, you will see the following tabs:
