In legal terminology, what term is often used to indicate that the matter is unimportant or irrelevant?

The term "frivolous" is commonly used in legal terminology to describe a matter that lacks any serious purpose or value, indicating that it is unimportant or irrelevant to the legal context at hand. In legal proceedings, for example, a frivolous lawsuit is one that has no reasonable basis in law or fact, often wasting the court’s time and resources.

This term is particularly relevant in court cases, as judges may dismiss frivolous claims to preserve judicial resources and maintain the integrity of the legal system. The use of "frivolous" effectively communicates the idea that the issue being discussed does not warrant serious consideration.

Other terms like "superficial," "peripheral," and "incidental" could imply a certain level of relevance or importance, possibly suggesting that although the matter may be secondary or minor, it still holds some significance. In contrast, "frivolous" clearly marks the matter as lacking merit altogether.
