Delaware Code
Chapter 99. APPEALS BY THE STATE IN CRIMINAL CASES
§ 9902. Appeal as of right.

(a) The State shall have an absolute right to appeal to an appellate court a final order of a lower court where the order constitutes a dismissal of an indictment or information or any count thereof, or the granting of any motion vacating any verdict or judgment of conviction where the order of the lower court is based upon the invalidity or construction of the statute upon which the indictment or information is founded or the lack of jurisdiction of the lower court over the person or subject matter.
(b) When any order is entered before trial in any court suppressing or excluding substantial and material evidence, the court, upon certification by the Attorney General that the evidence is essential to the prosecution of the case, shall dismiss the complaint, indictment or information or any count thereof to the proof of which the evidence suppressed or excluded is essential. Upon ordering the complaint, indictment or information or any count thereof dismissed pursuant to the Attorney General's certification, the reasons of the dismissal shall be set forth in the order entered upon the record.
(c) The State shall have an absolute right of appeal to an appellate court from an order entered pursuant to subsection (b) of this section and if the appellate court upon review of the order suppressing evidence shall reverse the dismissal, the defendant may be subjected to trial.
(d) The State shall have an absolute right to appeal to an appellate court from any order entered in a lower court which grants an accused any of the following:

(e) The State shall have an absolute right to appeal to an appellate court any ruling of a lower court on a question of law or procedure adverse to the State in any case in which the accused was convicted and appeals from the judgment, except that the decision or result of the State's appeal shall not affect the rights of the accused unless the accused, on his or her appeal, is awarded a new trial or a new sentencing hearing. Once the State perfects its cross-appeal, the appellate court shall review and rule upon the questions presented therein regardless of the disposition of the defendant's appeal.
(f) The State shall have an absolute right to appeal any sentence on the grounds that it is unauthorized by, or contrary to, any statute or court rule, in which case the decision or result of the State's appeal shall affect the rights of the accused.
(g) Any appeal brought by the State pursuant to subsection (e) or (f) of this section shall be personally authorized by either the Attorney General or the Chief Deputy Attorney General.
