John Jacobs (“Appellant”) appeals his conviction for aggravated robbery, for which he was sentenced to imprisonment for fifty years. Apрellant raises two issues on appeal. We affirm.
*632 Background
On the morning of April 28, 2001, Appellant entered a convenience store. When the store was сlear of patrons, Appellant brandished a knife and took all of the money from the cash register, causing the store clerk, Glenda Lightfoot, tо fear for her life. Appellant was indicted for aggravated robbery on July 27, 2001. Appellant’s indictment included two enhancement paragraphs for prior felony convictions of burglary of a building and aggravated robbery. Accordingly, Appellant’s status was enhanced to habitual offender, the рunishment range for which is imprisonment for twenty-five years to ninety-nine years or life. 1
Appellant’s trial counsel filed multiple pre-trial motions on Appеllant’s behalf. Among these pre-trial motions was Appellant’s motion for discovery of favorable or exculpatory evidence. A pre-trial hearing was held on November 8, 2001. At the conclusion of the pre-trial hearing, the trial court denied Appellant’s motion for discovery of favorable or exculpatory evidence, but ordered that the prosecution “disclose to the defense and his counsel any favorable and/or exculpatory evidence inconsistent with the-guilt of the accused pursuant to Brady.” 2 Subsequently, Appellant pleaded guilty and a hearing was held on punishment. Following the hearing, the trial judge sentenced Appellant to imprisonment for fifty years and this appeal followed.
Denial of Appellant’s Brady Motion
In his first issue, Appellant cоntends that in denying his motion, for discovery of favorable or exculpatory evidence, the trial court violated his right to due process. The Statе of Texas (the “State”) contends that Appellant, by pleading guilty, waived such error, if any. Whether entered with or without an agreed recommendatiоn of punishment by the State, a valid plea of guilty or
nolo contendere
waives or forfeits the right to appeal a claim of error if the judgment of guilt was rendered indeрendent of, and is not supported by, the error.
See Young v. State,
The instant case is distinguishable from Young. Unlike the judgment in Young, the trial court’s judgment in this case does not involve a motion tо suppress material evidence. In Young, the trial court’s judgment was unsupportable absent the evidence the appellant sought to suppress. Here, even assuming the contradicting witness statements at. issue existed at all and were ordered disclosed, the trial court’s judgment would still be supportablе in spite of their existence and disclosure. Therefore, we hold that by pleading guilty, Appellant has waived this issue on appeal. Appellant’s first issue is overruled.
Cruel and Unusual Punishment
In his second issue, Appellant contends that the trial court’s fifty-year sentence constituted cruel and unusual punishment under both the Texas and United States Constitutions. Initially, we note that Appellant made no objection to the
*633
trial court raising the issue of cruel and unusual punishment and has, thеrefore, waived such an issue with respect to any alleged violation of his rights under the Texas Constitution.
See Rhoades v. State,
The legislature is vested with the power to define crimes and prescribe penalties.
See Davis v. State,
Nonetheless, Appellant urges the Court to perform the three-part test set out in
Solem v. Helm,
court in
Davis
nevertheless evaluated the sentence under the elements of
Solem,
recognizing that seven of the justices in
Harmelin
still supportеd an Eighth Amendment prohibition against grossly disproportionate sentences.
See Davis,
In determining whether Appellant’s sentence is grossly disproportionate to the sentence imposed, we are guided by the holding in
Rummel v. Estelle,
But even assuming that the
Solem
test is still viable, or that the threshold test was satisfied, the remaining elements of
Solem
cannot be satisfied. There is no evidence in the appellate record reflecting the sentences imposed on criminals in Texas or other jurisdictions who cоmmitted a similar offense; therefore, we may not engage in a comparative evaluation.
See Simmons,
Accordingly, the judgment of the trial court is affirmed.
