14.276 Cases or court decisions
"Full case names in citations including the abbreviation v., are set in roman in notes; short forms in subsequent citations are italicized (as are full case names mentioned in textual sentences). Full citations include volume number, abbreviated name of the reporter(s), the ordinal series number of the reporter (if applicable), the abbreviated name of the court (if not indicated by the reporter) and the date together in parentheses, and other relevant information. A single page number designates the opening page of a decision; an additional number designates an actual page cited. In a shorted citation, at is used to cite a particular page; absence of at implies reference to the decision as a whole."
