How to Read a Supreme Court Case
You should try to use the
proper form for citation when you are writing your
case summaries, just for the practice.
| majority opinion | -This is the most important opinion of all the opinions issued because this opinion has a majority of the judges agreeing in both the judgment of the court and the legal reasoning behind the judgment. As such, this type of opinion carries the most weight of precedential authority. Typically only one Justice delivers the "opinion of the court," and the other Justices join in the opinion by signing on. |
| plurality opinion | When no one opinion has a majority of the Justices willing to sign on, the Court is fragmented about the legal reasoning and the outcome of the decision. As such, the different points that Justices want to make may be divided among different opinions rendered by the Justices. In essence, the plurality opinion is just the one opinion that has the most number of Justices that were willing to agree to it. It is sometimes called the "judgment of the Court." |
| concurring opinion | These opinions are additional opinions written by other Justices because one of the Justices in the majority wants to clarify some or all of the legal reasoning proffered by the majority opinion. The concurring Justice is essentially agreeing with the outcome of the opinion, but may disagree with some of the specific arguments presented by the majority opinion, or the Justice may want to express some reservations about how far the majority opinion goes in establishing the rule of law that is handed down. |
| concurring in judgment opinion | When the Justices hear a case, they are not only deciding who will win and who will lose, but they are trying to establish the legal reasoning as to why one outcome is preferred over another. As such, the Justices may agree that one party should win, but they may disagree about why. In these instances, one or more Justices may render a concurring in judgment opinion to clarify why they voted with the majority, but also why they disagree with the legal reasoning behind the majority opinion. These opinions are authored by Justices who are considered "swing votes" because without the one Justice agreeing with the judgment, the other Justices would not have enough votes to render a judgment. These opinions have weight as precedent because the opinion offers alternative legal reasoning that can be used in future cases. |
| concurring in part and dissenting in part opinion | These opinions are usually delivered when a Justice agrees with the legal reasoning of the majority opinion, but disagrees about how the legal reasoning applies to the case in terms of deciding who wins and who loses. The Justice may use the exact same legal framework relied upon by the majority opinion, but uses that reasoning to argue that the outcome of the decision (the judgment) should be different. Note that the Justice may only agree in part with the legal reasoning. |
| dissenting opinion | These are the losers! The dissenting opinion is issued by the Justices who do not agree with the majority opinion and have decided to write their own opinion about what they believe the outcome and the legal reasoning should be in a particular case. The precedential weight of these cases is very limited because the Court did not agree with the dissent. |
| per curiam decision | This is a decision that is unsigned that is usually thought to be less important than opinions that are signed. Often these decisions are made "summarily," that is, without oral argument. |
