OPINION ON APPELLANT'S PETITION FOR DISCRETIONARY REVIEW
ONION, Presiding Judge.
Appellant was convicted of possession of more than five but less than fifty pounds of marihuana. Article 4476-15, § 4.051, V.A.C.S. Punishment was assessed by the jury at 18 years' imprisonment.
On appeal, the Waco Court of Appeals affirmed the conviction after reviewing six grounds of error in an unpublished opinion.[1] We granted appellant's Petition for Discretionary Review to ascertain the correctness of that decision, to-wit: (1) whether the Court of Appeals erred in affirming the trial court's overruling of appellant's motion to quash the indictment due to the unconstitutionality of Article 4476-15, as amended by House Bill 730,[2] on the ground that the caption of the amendment failed to comply with the constitutional mandate of Article III, § 35 of the Texas Constitution;[3] (2) whether the Court of Appeals erred in affirming the trial court's overruling of appellant's motion to suppress evidence due to the unconstitutionality of the affidavit to the search warrant for its failure to comply with the first prong of Aguilar v. Texas, 378 U.S. 108, 84 S.Ct. 1509, 12 L.Ed.2d 723 (1964). Due to our disposition of the first ground of error, we do not address this latter ground.
At the outset, we note that appellant raises the identical issue that this court dealt with earlier in Ex parte Crisp, 661 S.W.2d 944 (Tex.Cr.App.1983), in declaring Article 4476-15, as amended by House Bill 730, unconstitutional. The holding in Crisp, applies to appellant herein.
However, in Crisp we refused to set aside the convictions because "the Controlled Substances Act remained in effect as though H.B. 730 had never been enacted" (Ex parte Crisp, 661 S.W.2d, at 948), because when an amendment to an act (which is what H.B. 730 was) is declared unconstitutional and invalid, the original act remains in full force and effect, even if the amendment has no savings clause. White v. State, 440 S.W.2d 660, at 667 (Tex.Cr.App.1969), citing Doucette v. State, 166 Tex.Cr.R. 596, 317 S.W.2d 200 (1958).
In appellant's case, however, we are unable to take the same action as we did in Crisp. Although the indictment herein could be interpreted to allege an offense under the law as it existed prior to the enactment of H.B. 730,[4] the classification of such an offense under the prior law (and *736 now existing law since Crisp) is a third degree felony, whereas it was classified as a second degree felony under the H.B. 730 amendment to Article 4476-15, V.A.C.S. Since appellant was tried by a jury,[5] could not have been convicted of a second degree felony, and could not have been assessed punishment at 18 years under the law as it existed prior to the enactment of H.B. 730,[6] we must reverse his conviction.
The holding of the Court of Appeals is reversed and this cause is remanded. See Ex parte Padilla, 666 S.W.2d 111 (Tex.Cr. App.1984).
