Which of the following is NOT a typical component of legal citation?

In legal citation, a typical case citation includes essential elements that provide specific information about the case, facilitating easier access and reference. The title of the case identifies the parties involved and is a fundamental part of the citation. The year of the decision indicates when the case was adjudicated, which is critical for understanding the temporal context of the ruling and its relevance to subsequent legal principles.

The page number denotes where the case can be found within a specific reporter, which is crucial for locating the full text of the decision. It allows anyone referencing the case to find the precise location of the decision in legal publications.

While a case number might be used in specific contexts, such as referencing cases within court filings or databases, it is not a standard component of legal citation in the same way that the title of the case, year of decision, and page number are. Thus, the case number is not necessary for a complete citation and, therefore, is the correct choice in identifying the element that is not typically included in general legal citations.
