Judge Mascio asserts that the court of appeals erred in granting the prosecuting attorney the requested writ of prohibition. In order to be entitled to a writ of prohibition, the prosecuting attorney is required to establish (1) that Judge Mascio was about to exercise judicial power, (2) that Judge Mascio's exercise of such power was unauthorized by law, and (3) that refusal of the writ would cause the prosecuting attorney injury for which he has no other adequate remedy in the ordinary course of law. State ex rel. Thurn v. Cuyahoga Cty. Bd. of Elections (1995), 72 Ohio St.3d 289, 291, 649 N.E.2d 1205, 1207. It is uncontroverted that Judge Mascio was about to hold a hearing on the affirmative defense of personal use specified in R.C. 2925.03(F). Therefore, the first requirement for the issuance of a writ of prohibition was met.

As to the second requirement for a writ of prohibition, Judge Mascio claims in his sole proposition of law that a common pleas court judge must grant a criminal defendant who pleads no contest to a felony charge of trafficking in marijuana in violation of R.C. 2925.03(A)(4) the opportunity to prove the affirmative defense that the marijuana was solely for personal use under R.C. 2925.03(F). R.C. 2925.03(A)(4) provides that no person shall knowingly "[p]ossess a controlled substance in an amount equal to or exceeding the bulk amount, but in an amount less than three times that amount[.]" R.C. 2925.03(F) provides that "[i]t shall be an affirmative defense, as provided in section 2901.05 of the Revised Code, to a charge under this section for possessing a bulk amount of a controlled substance or for cultivating marihuana that the substance that gave rise to the charge is in such amount, in such form, or is prepared, compounded, or mixed with substances that are not controlled substances in such a manner, or is possessed or cultivated in any other circumstances whatsoever as to indicate that the substance was solely for personal use."

While a plea of guilty is a complete admission of the defendant's guilt, a plea of no contest is not an admission of guilt, but is an admission of the truth of the facts alleged in the indictment, information, or complaint. Crim.R. 11(B)(1) and (2). The trial court thus possesses discretion to determine whether the facts alleged in the indictment, information, or complaint are sufficient to justify conviction of the offense charged. State v. Thorpe (1983), 9 Ohio App.3d 1, 3, 9 OBR 1, 3, 457 N.E.2d 912, 915 (Markus, J., concurring). If the court determines that the alleged facts are insufficient to state the charged offense, it may find the defendant guilty of a lesser included offense, State ex rel. Leis v. Gusweiler (1981), 65 Ohio St.2d 60, 61, 19 O.O.3d 257, 418 N.E.2d 397, 398, or dismiss the charge.

Although a plea of no contest does not admit a defendant's guilt, Crim.R. 11(C) requires that the same procedure be followed by the trial court in accepting pleas of guilty and no contest in felony cases. See State v. Pernell (1976), 47 Ohio App.2d 261, 265, 1 O.O.3d 318, 321, 353 N.E.2d 891, 894. In felony cases, the trial court shall not accept a plea of guilty or no contest without informing the defendant and determining that he understands the effect of his plea, and that the court may proceed with judgment and sentence after accepting the plea. Crim.R. 11(C)(2)(b). The guilty or no contest plea also effects a waiver of the defendant's rights to jury trial, to confront witnesses against him, to have compulsory process for obtaining witnesses in his favor, and to require the state to prove his guilt beyond a reasonable doubt at a trial at which he cannot be compelled to testify against himself. Crim.R. 11(C)(2)(c).

The procedure specified in Crim.R. 11(C) does not envision an affirmative-defense hearing or mini-trial, such as the one previously held by Judge Mascio in a case similar to the underlying case, which resulted in acquittal of the defendant on the charged trafficking offense. "`The essence of the "no contest" plea, is that the accused cannot be heard in defense. Thus any statement by him must be considered as in mitigation of penalty.'" State v. Herman (1971), 31 Ohio App.2d 134, 140, 60 O.O.2d 210, 214, 286 N.E.2d 296, 300, quoting Rueger, Schneider's Ohio Criminal Code (3 Ed. 1963) 49, Section 10.1, fn. 4; State v. McMillen (Mar. 16, 1989), Franklin App. No. 88AP-477, unreported, 1989 WL 252398.

Although the trial court retains discretion to consider a defendant's contention that the admitted facts do not constitute the charged offense, the defendant who pleads no contest waives the right to present additional affirmative factual allegations to prove that he is not guilty of the charged offense. See State v. Gilbo (1994), 96 Ohio App.3d 332, 337, 645 N.E.2d 69, 72; see, also, State v. McCuen (June 16, 1995), Columbiana App. No. 92-C-83, unreported, 1995 WL 360764. By pleading no contest, the defendant waives his right to present an affirmative defense. See State v. Harris (Mar. 31, 1994), Franklin App. No. 93APA12-1726, unreported, 1994 WL 110709. In this respect, Ohio's no contest plea is similar to the "nolo contendere" plea in other jurisdictions. See, generally, 1 Wright, Federal Practice and Procedure (1982) 662-665, Section 177; LaFave Israel, Criminal Procedure (1985) 801-802, Section 20.4(a).

Notwithstanding the foregoing, Judge Mascio contends that a defendant's right to assert an affirmative defense is a substantive right created by R.C. 2925.03(F) which is not superseded by the conflicting procedure specified in Crim.R. 11. See Cuyahoga Falls v. Bowers (1984), 9 Ohio St.3d 148, 9 OBR 438, 459 N.E.2d 532, syllabus ("The provision in R.C. 2937.07 requiring an explanation of circumstances [in misdemeanor cases] following a plea of no contest has not been superseded by the enactment of Crim.R. 11 because the statutory provision confers a substantive right."). However, there is no conflict. A defendant may still raise an affirmative defense by pleading not guilty to the charged offense and stipulating to the facts set forth in the indictment, information, or complaint. Crim.R. 11 and pertinent case law merely require that if a defendant enters a no contest plea to a felony offense, the procedures set forth in the rule, which are similar for no contest and guilty pleas, must be followed.

Therefore, where the indictment, information, or complaint contains sufficient allegations to state a felony offense and the defendant pleads no contest, the trial court must find the defendant guilty of the charged offense. See State v. Rader (1988), 55 Ohio App.3d 102, 563 N.E.2d 304; see, also, 2 Schroeder-Katz, Ohio Criminal Law and Practice (1992) 248, Section 33.01. Judge Mascio ordered an affirmative defense "hearing," at which he will consider evidence not solely in mitigation of the sentence to be imposed for trafficking in marijuana. The prosecutor thus established that Judge Mascio's contemplated exercise of power is unauthorized.

Finally, as to the final requirement for the issuance of a writ of prohibition, the prosecutor arguably had adequate remedies in the ordinary course of law to contest Judge Mascio's decision to hold an affirmative-defense hearing, i.e., an R.C. 2945.67 discretionary appeal by leave of court and a motion to stay the criminal proceedings pending consideration of the appeal. See, e.g., State ex rel. Corrigan v. Griffin (1984), 14 Ohio St.3d 26, 27, 14 OBR 328, 329, 470 N.E.2d 894, 895. However, where a lower court is without jurisdiction whatsoever to act, the availability or adequacy of an appellate remedy is immaterial. State ex rel. Yates v. Montgomery Cty. Court of Appeals (1987), 32 Ohio St.3d 30, 33, 512 N.E.2d 343, 346. Since the trial court patently and unambiguously lacked authority to hold an affirmative-defense hearing following its acceptance of the no contest plea, the court of appeals properly determined that a writ of prohibition should issue.

Accordingly, we affirm the judgment of the court of appeals.

Judgment affirmed.
