The commencement of a criminal action is defined by the filing of an accusatory instrument. This legal term encompasses various documents that formally accuse an individual of committing a crime, which may include an indictment, information, or misdemeanor complaint. The use of "accusatory instrument" reflects the specificity required in criminal proceedings to adequately inform the defendant of the charges they face.

While a legal complaint might be a term used in civil litigation, it does not apply to the framework of criminal law, where the terminology is distinctively focused on criminal charges. Similarly, a civil suit pertains to disputes between private parties and does not initiate a criminal proceeding. An arrest warrant, although related to the apprehension of a defendant, serves as a mechanism for law enforcement to arrest an individual and does not itself commence a court action.

Thus, the characterization of the document as an accusatory instrument is crucial to understanding how criminal actions begin, emphasizing the procedural requirements intrinsic to the criminal justice system.
