Term data
Precedent alteration
The Washington University in St. Louis Law School (WashU Law) maintains a database of Supreme Court cases. In its database, a case is considered to have formally altered existing Court precedent if at least one of the following applies to the case:[1]
- The majority opinion of the Court explicitly references a previous case and overturns its precedent;
- A dissent contains persuasive evidence that the opinion of the Court, despite not mentioning overturned precedent, has overruled a previous precedent set by the Court;
- If the Court, in a later decision, references an earlier decision that the Court made, and states that said earlier decision was a case overturning precedent, that earlier case will be marked as altering precedent;
- Or, the majority opinion mentions precedent and states that it "disapproved" of the decision, or that the precedent is "no longer good law."
The following table details for each term of The Roberts Court how many and which cases were found to formally alter precedent:[2]
Note that the WashU Law database does not state how many precedents were overturned with each decision. As such, a case listed as altering a precedent may have affected multiple precedents.
Additionally, if the Court only distinguished a precedent, it was not classified as a precedent-altering case. Distinguishing a precedent involves clarifying a previous precedent rather than changing it.[1]
Justice alignment
The following justice alignment table shows justice agreement rates for non-unanimous rulings during the 2017-2018 term. The data does not include agreements in part.
- The highest agreement rate was 95 percent, which applied to the following pairing:
- Justices Ruth Bader Ginsburg and Sonia Sotomayor
- Justice Anthony Kennedy had the highest average agreement rate with each of the other eight justices at 73 percent
- The lowest agreement rate was 43 percent, which applied to the following pairing:
- Justices Samuel Alito and Sonia Sotomayor
- Justice Sonia Sotomayor had the lowest average agreement rate with each of the other eight justices at 67 percent
