General Rules for Court & Date

The last major part of a case citation is the court and date, contained in a parenthetical following the case location. The reader should easily be able to ascertain what court decided the case, its geographical jurisdiction, and the year of the decision. Table 1 includes the abbreviations for courts in the United States. Some basic rules apply to the court and date portion of case citations:

State Courts - Include both the name of the state and the name of the court, omitting the court name if it is the highest court in the jurisdiction.

Mich. Ct. App. (Michigan Court of Appeals)
Mich. (Michigan Supreme Court)

Not: People v. Armour, 590 N.W.2d 61 (Mich. 1999).
Not: People v. Armour, 590 N.W.2d 61 (Mich. Sup. Ct. 1999).

Generally - Omit court abbreviation if unambiguously conveyed by the reporter title.

But: Commonwealth v. Virelli, 620 A.2d 543 (Pa. Super. Ct. 1992).

Court & Date Abbreviations

Generally - Abbreviate court names and geographic jurisdictions according to Table 1 and Table 2. If not found within those tables, follow Table 7 and Table 10.

U.S District Courts - Combine district and state abbreviations, along with abbreviation for multiple districts if applicable. Do not include the division, however.

D. Mass. (District of Massachusetts)
S.D.N.Y. (Southern District of New York)
C.D. Cal. (Central District of California, Eastern Division)
Not: C.D. Cal. E.D. 

U.S Courts of Appeals - Combine circuit and numerical abbreviations.

Tips

When indicating the date in a reported case citation, only include the date the case was decided, not argued or heard.
