Which form does a disposition typically take?

The correct choice, a legal decision or judgment in a case, accurately defines the nature of a disposition within the legal context. A disposition refers to the outcome of a legal proceeding, such as a trial or hearing, where the court determines the fate of a case. This can include rulings on guilt or innocence, sentencing, or the resolution of the case through plea agreements.

In contrast, the other options do not encapsulate the formal and procedurally defined essence of a disposition. A sworn witness statement is a document that contains the testimony of a witness but does not represent the resolution of a case. An informal recounting of events lacks the formal structure and legal significance that a disposition holds. Similarly, a character reference letter serves to provide insight into a person's character but is not tied to the legal ruling or resolution of a case. Thus, the essence of a disposition is accurately represented by the understanding that it constitutes a legal decision or judgment.
