Shepard's is Lexis’s citator. Similiar to KeyCite, Shepard's uses signals to indicate negative treatment or negative history.
Positive Treatment: This tells you that there have been cases that had a positive impact on yours in some way
Warning (Statutory): This tells you that citing references contain some negative treatment regarding your case. This may be that it has been found unconstitutional or void
Warning: This tells you that citing references contain negative history or that the case may have been overruled in at least one point of law.
Questioning: This tells you that citing references contain treatment that questions the validity of at least on point of law in your case.
Caution: This means there is history of treatment that has a negative impact on your case.
Neutral: This means there are citing references for your case but they are neither negative nor positive.
Information Available: This means there are citing sources available for your case but they do not have history or treatment analysis. These could be secondary sources.
A synopsis of Shepard’s information is located on the right side of the case. The synopsis shows: prior or subsequent history; number of citing decisions (with signals indicating whether treatment is positive or negative) and number of other citing sources.
Researchers can click individual items in the synopsis or they can choose to “Shepardize this document” for the complete report (including table of authorities).
