There are two ways to see if a case has been treated negatively by subsequent cases in Casemaker. The first way is a feature called Citing References. Citing References provides a list of every case in Casemaker that has cited the original opinion and is available on the grey navigation bar displayed while viewing a case. You would need to review each of these cases to see if any case treated the original case negatively or not.
The second way is CaseCheck+. CaseCheck+ takes the Citing References feature one step further and will automatically indicate if any subsequent cases have negatively treated the original case and what the treatment is. A green thumbs up symbol indicates there is no subsequent negative treatment and a red thumbs down symbol indicates there is negative treatment in subsequent cases.
