State court cases are often published in more than one place. A state court case decision may be published in an official state reporter, if the state has one. State court cases may also be published in a regional reporter, which are commercially published (unofficial) reporters containing appellate court and state supreme court decisions from states in a particular region of the United States. To see what states are included in each regional reporter, check out Westlaw's Regional Reporters Map.
Relevant Rules and Tables in The Bluebook
Elements to a State Case Citation with a Regional Reporter
Here is an example:
State v. Zurawski, 690 S.W.3d 644 (Tex. 2024)
The reason the court is only "Tex." and not "Tex. Sup. Ct." is because of Rule 10.4(b). The Bluebook dictates that in general, you should indicate the state and court of the decision; however, do not include the name of the court if the decision comes from the highest court of the state.
Elements of a State Case Citation with a Official State Reporter
Here is an example:
Goldrush II v. City of Marietta, 267 Ga. 683 (1997)
The reason the court and state are not included in the parenthetical information is because of Rule 10.4(b). Rule 10.4(b) states that if the jurisdiction and/or the court are unambiguously conveyed by the reporter title, omit putting the jurisdiction and/or court in the parenthetical information.
Illinois' Style Citation Sources
The Bluebook provides specific information on courts and their abbreviations on pp. 225-56.
If the court document you are filing is for the Supreme Court of Illinois or appellate jurisdiction, the Illinois Supreme Court adopted, in 2024, the Style Manual for the Supreme and Appellate Courts of Illinois, which took effect on January 1, 2025.
The Style Manual provides guidance to: (1) structuring an opinion; (2) grammatical style; and (3) citation style.
Illinois Published Opinions
Illinois used to publish its decisions in official state reporters: Illinois Reports (Illinois Supreme Court) and Illinois Appellate Court Reports (Illinois appellate decisions). However, in 2011, Illinois stopped publishing the printed official reporters and began issuing electronic versions of both the Illinois Supreme Court and Appellate Courts decisions on Illinoiscourts.gov. For cases accessed this way, use The Bluebook's public domain formatting (p. 255).
Illinois decision can also be found in the North Eastern Reporter and West's Illinois Decisions.
