Rules of construction; use of "shall." Provides that "shall," as used in the Code of Virginia, establishes a mandatory requirement and is not merely directory, unless the statute explicitly provides otherwise. The bill responds to the holding in Henderson v. Commonwealth , 77 Va. App. 250 (2023), in which the Court of Appeals held that when the General Assembly uses "shall" in a statute commanding action by a public official or public body such usage is directory and not mandatory.
