In legal terms, what is a motion?

A motion is indeed defined as a formal request made to a court for a specific ruling or order. This legal tool allows parties involved in a court case to seek a variety of decisions from the judge, whether it be to compel a party to perform an action, ask for dismissal of a case, or to introduce evidence. Motions are integral to the legal process and serve as means for attorneys to request the court's intervention in managing the case or facilitating a decision on specific issues that arise during litigation.

The other options, while related to legal proceedings, serve different functions. A written document outlining a case's evidence focuses on the presentation of facts and arguments, not a direct request for an order. A form of appeal against a court decision refers to a procedure by which a party seeks review of a lower court's ruling, which is distinct from the motion process. A legal summons issued to defendants pertains to notifying them about a legal action and ordering them to appear in court, but does not involve making a request for a ruling. Understanding these distinctions can clarify the different roles these terms play in the legal system.
