The decisions of the Courts of Appeal are binding on the
Superior Courts of California, and both the Courts of Appeal and the Superior Courts are bound by the decisions of the
Supreme Court of California. Notably, all published California appellate decisions are binding on all trial courts[SUP]
[2][/SUP] (distinct from the practice in the
federal courts and in other state court systems in which trial courts are bound only by the appellate decisions from the particular circuit in which it sits, as well as the
Supreme Court of the United States or the
state supreme court).[SUP]
[3][/SUP] Court of Appeal decisions are not binding between divisions or even between panels of the same division.[SUP]

It is customary in federal courts and other state courts to indicate in case citations the particular circuit or district of an intermediate appellate court that issued the decision cited. But because the decisions of all six California appellate districts are equally binding upon all trial courts, district numbers are traditionally omitted in California citation style unless an actual interdistrict conflict is at issue.
All California appellate courts are required by the
California Constitution to decide criminal cases in writing with reasons stated (meaning that even in criminal appeals where the defendant's own lawyer has tacitly conceded that the appeal has no merit,[SUP]
[5][/SUP] the appellate decision
must summarize the facts and law of the case and review possible issues independently before concluding that the appeal is without merit).[SUP]
[6][/SUP] Such procedure is not mandated for civil cases, but for certain types of civil cases where a liberty interest is implicated, the Courts of Appeal may, but are not required to, follow a similar procedure.[SUP]

[8][/SUP] Most Court of Appeal opinions are not published and have no precedential value;[SUP]
[9][/SUP] the opinions that are published are included in the official reporter,
California Appellate Reports.
