S.D. Codified Laws § 23A-2-1
A complaint is a written statement of the essential facts constituting an offense charged. The complaint shall be signed under oath before a person authorized to administer oaths in the State of South Dakota. A law enforcement officer, in lieu of signing a complaint for a misdemeanor or felony under oath, may sign a statement printed or written on a complaint or summons on a uniform traffic ticket stating: "I declare and affirm under the penalties of perjury that this complaint or summons has been examined by me, and to the best of my knowledge and belief, is in all things true and correct." Any person who signs a statement as required by this section, knowing the statement to be false or untrue, in whole or in part, is guilty of perjury.
