OPINION
delivered the opinion of the court,
We granted this appeal to determine whether the prosecution’s failure to elect the particular offense of aggravated rape upon which it sought to convict the defendant constituted plain error and required a new trial. The main purpose of the election requirement is to preserve a defendant’s right to a unanimous jury verdict under the Tennessee Constitution. A majority of the Court of Criminal Appeals affirmed the defendant’s conviction for one count of aggravated rape without examining the election issue. After reviewing the record and controlling authority, we conclude that the prosecution’s failure to elect the particular offense upon which it sought to convict the defendant failed to preserve the defendant’s rights under the Tennessee Constitution and constituted plain error. The judgment of the Court of Criminal Appeals is reversed, and the case is remanded to the trial court for a new trial.
On May 15, 1995, the defendant, Antonio Kendrick, forced the victim, Mareelita Hester, into his car. According to Hester, Kendrick was in possession of a metal bar or wrench. While driving, the defendant asked Hester whether she remembered him and accused her of cursing at him at a grocery store on an earlier occasion. Hester did not recall Kendrick or any such incident. After awhile, Kendrick stopped the car; threatened to harm Hester; and forced her to perform fellatio on him. After driving for another five or ten minutes, Kendrick again stopped the car and forced Hester to engage in vaginal intercourse.
We granted review to consider the election of offenses issue.
ANALYSIS
This Court has long and consistently held that “when the evidence indicates [that] the defendant has committed multiple offenses against a victim, the prosecution must elect the particular offense as charged in the indictment for which the conviction is sought.”
State v. Brown,
The paramount importance of the election requirement is that it protects a defendant’s right to a unanimous jury verdict under the Tennessee Constitution by ensuring that jurors deliberate over and render a verdict based on the same offense.
State v. Brown,
[T]here should be no question that the unanimity of twelve jurors is required in criminal cases under our state constitution. A defendant’s right to a unanimous jury before conviction requires the trial court to take precautions to ensure that the jury deliberates over the particular charged offense, instead of creating a “patchwork verdict” based on different offenses in evidence.
State v. Shelton,
Turning to the facts of this case with these principles in mind, we first address the State’s threshold argument that an election of offenses was not required because the defendant’s conduct constituted a single, continuous offense. As noted above, one of the elements of aggravated rape is “unlawful sexual penetration of a victim by the defendant or the defendant by a victim.”
See
Tenn.Code Ann. § 39-13-502(a) (1997). The element of “unlawful sexual penetration” means “sexual intercourse, cunnilingus, fellatio, anal intercourse, or any other intrusion, however slight, of any part of a person’s body or of any object into the genital or anal open-
Like the statutory definitions, our case law also makes clear that the sexual acts committed in this case were separate and distinct. We have observed that “ ‘although separate acts of intercourse may be so related as to constitute one criminal offense,’ ” the pertinent analysis requires consideration of numerous factors.
See State v. Phillips,
Given our conclusion that there was evidence of two separate offenses that would satisfy the definition of aggravated rape, we agree with Judge Wade’s dissenting view that an election of offenses was required in this case. The record indicates, however, that the trial court did not require the prosecution to make an election of offenses and that the prosecution did not do so at the close of the evidence. Although the defense apparently did not request an election of offenses, we have stressed that the election requirement is a responsibility of the trial court and the prosecution and, therefore, does not depend on a specific request by a defendant.
See State v. Walton,
As our cases have made crystal clear, the prosecution’s failure to elect was an error that was “fundamental, immediately touching [upon] the constitutional rights of [the] accused.”
Burlison v. State,
It has been suggested that when a defendant denies all sexual contact with the victim, but the proof is sufficient to support guilty verdicts beyond a reasonable doubt on all of the offenses in evidence, an election is unnecessary.... [A]n appellate court’s finding that the evidence is sufficient to support convictions for any of the offenses in evidence is an inadequate substitute for a jury’s deliberation over identified offenses.
State v. Shelton,
CONCLUSION
After reviewing the record and controlling authority, we conclude that the prosecutor’s failure to elect the particular offense upon which it sought a conviction failed to preserve the defendant’s rights under the Tennessee Constitution and constituted plain error. Tenn. R.Crim. P. 52(b). Accordingly, the judgment of the Court of Criminal Appeals is reversed, and the case is remanded to the trial court for a new trial. Cost of this appeal shall be taxed against the State.
Notes
. As pertinent to this case, aggravated rape is defined as "unlawful sexual penetration of a victim by the defendant or the defendant by a victim” where "force or coercion is used to accomplish the act and the defendant is armed with a weapon or any article used or fashioned in a manner to lead the victim reasonably to believe it to be a weapon.” Tenn.Code Ann. § 39-13-502(a)(l) (1997).
. Indeed, had the defendant been indicted for two separate counts based on the facts of this case, it is easy to envision that the State would have argued that the offenses were separate and distinct under Phillips.
