The opinion of the Court was delivered by
In this appeal defendant claims he was denied the effective assistance of counsel because his attorney failed to raise a double jeopardy defense prior to defendant’s trial on various drug offenses after the attorney had objected to an earlier grant of a mistrial on the same charges. The Appellate Division determined that defendant waived his double-jeopardy claim by failing to file a

3:10-2 motion raising the defense. The panel also found that the consequences of the attorney’s decision were not sufficient to establish the showing of prejudice necessary to sustain a claim of ineffective assistance of counsel under

I.
In January 1997, police officers conducted a vehicular stop of the automobile in which defendant, Al-Muhhye Allah, and co-defendant, Geraldo Garcia, were traveling. Garcia, the driver, had failed to obey a stop sign. One of the officers noticed an open cardboard box containing envelopes of heroin on the floor of the passenger’s side of the vehicle and brought that observation to the attention of defendant and Garcia. Defendant ran from the vehicle, but was caught and arrested. Garcia was prevented from fleeing.
Defendant and Garcia were indicted on four counts: (1) second degree conspiracy, contrary to N.J.S.A. 2C:5-2 (Count One); (2) third degree possession of a controlled dangerous substance (heroin), contrary to N.J.S.A. 2C:35-10a(1) (Count Two); (3) second degree possession with intent to distribute, contrary to N.J.S.A. 2C:35-5b(2) (Count Three); and (4) third degree possession with intent to distribute within 1000 feet of a school, contrary to N.J.S.A. 2C:35-7 (Count Four). Prior to defendant’s trial, Garcia entered into a plea agreement with the State in accordance with which he pled guilty to Counts One, Three, and Four and agreed to testify at defendant’s trial. When providing the factual basis for his plea, Garcia stated that he and defendant jointly purchased the heroin, which they intended to sell, and that at the time of the arrest the box with the heroin was under the driver’s seat of the car. At the time of jury selection in defendant’s trial, Garcia had not been sentenced.
Defendant’s first trial ended mid-trial when the court granted a mistrial on motion by the State. The following facts are relevant to the trial court’s finding of manifest necessity for the mistrial.
At trial, defendant’s counsel subpoenaed Garcia as a defense witness. Notwithstanding the negotiated plea agreement that required Garcia to testify for the State, the State concluded its *275 case without calling Garcia. Defense counsel then called Garcia to testify. During direct examination Garcia disclosed that he voluntarily pled guilty to the charges contained in the indictment and that as part of his plea agreement he agreed to testify at defendant’s trial in exchange for a more lenient sentence. Concerning the charges against defendant, Garcia testified that on the evening of his arrest, he was driving an automobile with defendant as a passenger. Garcia stated that he placed a box containing small envelopes of heroin under the driver’s seat. In addition to the location of the box, Garcia described the configuration of the box as it appeared on the ear floor along with some newspapers, implying that the heroin could not be seen. Garcia’s testimony suggested that defendant was innocent.
While Garcia’s direct examination was in progress, his attorney entered the courtroom on an unrelated matter. When the trial court declared a recess, Garcia’s attorney informed the court that she was not aware that her client was to testify that day. She requested an opportunity to speak to him because, although Garcia had previously entered a guilty plea, he had not been convicted and sentenced, and thus his ease remained open. She argued that Garcia could assert his Fifth Amendment right against self-incrimination and refuse to testify. The trial court allowed the consultation with Garcia.
When the trial reconvened, defense counsel announced that Re had no further questions for the witness. In response to the State’s first question on cross-examination, Garcia asserted his Fifth Amendment right against self-incrimination and the State moved for a mistrial. Defense counsel immediately objected to the request for a mistrial, contending that the defense’s actions did not cause the mistrial and that other options were available to the court:
The assertion that a mistrial in this case was caused by the [d]efense, I just do not understand. Because from the very beginning, with regard to my intention to call Mr. Garcia as a witness in this ease, my intention was made known to everyone in this case from the very outset. . . .
*276 This case was pled out Tuesday afternoon. I left here Tuesday afternoon with the expectation that Mr. Garcia was going to be a witness for the State; that he was going to testify against my client at his trial; that he was going to implicate my client as his co-defendant. That was a requirement of the plea. As painfully as he gave that factual basis, and had to be coerced through the factual basis, that was a requirement of his plea. . . .
Now, the next day Wednesday, February 4th, we come to this Court. And we don’t really know for sure if Mr. Garcia is going to testify in behalf of the State. . . . But then we’re told during the course of the [p]rosecutor’s opening, that Mr. Garcia is not going to be called as a witness for the State. Before I said anything to the jury about Mr. Garcia perhaps testifying in behalf of [the] defense, I asked for a side bar. I told your Honor and [the prosecutor]. I just think I heard [the prosecutor] say he is not going to call Mr. Garcia. I intended to. I said I intended to because I’m going to tell that jury that Mr. Garcia pled guilty. We all agreed that I could tell the jury that he pled guilty, as long as I was making the representation that I intended to call him....
I get a subpoena____
Mr. Garcia is now called as a defense witness. . . .
I asked him a couple of questions about his plea. I ask him one question, totally consistent with what he said in his plea hearing that the box was found underneath the driver’s seat. That is exactly what he said. That’s exactly what he said in his plea hearing. And I asked him how is the box bound. Now defense counsel is causing a mistrial in this trial, in this case[?] Really, [the prosecutor] could guarantee no mistrial in this case right now. Because I just said I’m not going to ask this gentleman another question on direct. [The prosecutor] can cross examine this man to his heart’s content [.]...
So I have a serious problem with a mistrial. . . . I guess your Honor has to entertain a mistrial. But to say defense caused a mistrial in this case; I don’t get it. I think that this case should be allowed to go to the jury. I think you should tell this jury to disregard that. Or better yet, ... let [the prosecutor] cross examine Mr. Garcia to his heart’s content.
The trial court granted the mistrial, stating that:
It is clear to me that the problem here is that at a point in direct examination of a co-defendant who had previously entered a plea of guilty, who hadn’t been sentenced. So clearly, the Fifth Amendment privilege still attaches. He decides after consulting with counsel that he wishes to ... [take] the Fifth Amendment. Defense counsel indicates that direct was concluded. [The][p]rosecutor clearly has a right to cross-examination. . . . For whatever reason, the decision to take the Fifth is not made until after direct examination. . . . Clearly[,] the witness ... after consulting with counsel[,] has a right to take the Fifth Amendment. Clearly[,] that results in creating a very unfair playing field. Can I tell the jury to disregard direct examination? I can tell them that ... [but,] I don’t think I can erase it from their minds.... I don’t believe that the prejudice resulting from the error is of the nature which can be effectively cured by [a] cautionary instruction or any other *277 curative step. I think I have no recourse other than to declare a mistrial. . . . That is without prejudice.
A second trial was held before another judge. At no time prior to or during trial did defense counsel move for dismissal of the indictment on double jeopardy grounds. Defendant was convicted of third degree possession of a controlled dangerous substance (Count Two) and acquitted on all other counts. He was sentenced on Count Two to a five-year term, with a two-year period of parole ineligibility. The trial court imposed the appropriate fines and penalties.
Defendant appealed and the Appellate Division affirmed the conviction and sentence.
State v. Allah,
334
N.J.Super.
516,
Finally, the panel held that defense counsel’s failure to move to dismiss the indictment on double jeopardy grounds did not violate defendant’s constitutional right to effective assistance of counsel.
Id.
at 529,
There is no sense in which it can be said that his attorney’s failure to file a timely motion to dismiss the indictment rendered the actual trial unfair. The conviction was not caused by ineffective representation during the trial; nor was the trial marred by the admission of constitutionally tainted evidence as a x’esult of pretrial ineffectiveness. Recognition of the right to claim double jeopardy at this point would serve little pui’pose, other than permitting defendant to avoid a conviction fully supported by the evidence, since the defendant has already undergone the stress and expense of the second trial.

In addition to the constitutional prohibition, N.J.S.A. 2C:1-9 provides statutory protection from double jeopardy:
A prosecution of a defendant for a violation of the same provision of the statutes based upon the same facts as a former prosecution is barred by such former prosecution under the following circumstances:
d. The former prosecution was improperly terminated. Except as provided in this subsection, there is an improper termination of a prosecution if the termination is for reasons not amounting to an acquittal, and it takes place after the jury was impaneled and sworn____Termination under any of the following circumstances is not improper:
(3) The trial court finds that the termination is required by a sufficient legal reason and a manifest or absolute or overriding necessity.
In a non-jury trial, jeopardy attaches when the first witness is sworn.

The record in this matter reflects that the State moved for a mistrial after Garcia concluded his direct examination for the defense and then refused to answer questions during cross-examination. The Appellate Division determined that Garcia was not entitled to rely on the Fifth Amendment privilege against self-incrimination, and that therefore his invocation of the privilege did not create manifest necessity warranting a new trial.

Rule 3:10-2(c) sets forth those defenses and objections that must be raised before trial:
The defense of double jeopardy and all other defenses and objections based on defects in the institution of the prosecution or in the indictment or accusation, except as otherwise provided by R. 3:10-2(d) (defenses which may be raised only *282 before or after trial) and R. 3:10-2(e) (lack of jurisdiction), must be raised by motion before trial. Failure to so present any such defense constitutes a waiver thereof, but the court for good cause shown may grant relief from the waiver.
The plain language of the
Rule
provides that the defense of double jeopardy must be raised by motion before trial and that the failure to present the defense constitutes a waiver.

Defendant claimed that the failure of his lawyer to raise the double jeopardy issue before the retrial constituted ineffective assistance of counsel and thus met the good cause standard. Based on its determination that defendant did not establish a claim for ineffective assistance of counsel, the Appellate Division held that he failed to demonstrate good cause.

Strickland
recognized that an attorney can deprive a defendant of the right to effective assistance of counsel by failing to render adequate legal advice. 466
U.S.
at 686, 104
S.Ct.
at 2064,
First, the defendant must show that counsel’s performance was deficient. This requires a showing that counsel made errors so serious that counsel was not functioning as the “counsel” guaranteed the defendant by the Sixth Amendment. Second, the defendant must show that the deficient performance prejudiced the defense. This requires a showing that counsel’s errors were so serious as to deprive the defendant of a fair trial, a trial whose result is reliable. Unless a defendant makes both showings, it cannot be said that the conviction ... resulted from a breakdown in the adversary process that renders the result unreliable.
[Id. at 687,104 S.Ct. at 2064,80 L.Ed.2d at 693 (emphasis added).]
The Strickland Court further elaborated on the prejudice prong, noting:
[T]he appropriate test for prejudice finds its roots in the test for materiality of exculpatory information not disclosed to the defense by the prosecution, ... and in the test for materiality of testimony made unavailable to the defense by Government deportation of a witness[ ]. . . . The defendant must show that there is a reasonable probability that, but for counsel’s unprofessional errors, the result of the proceeding would have been different. A reasonable probability is a probability sufficient to undermine confidence in the outcome.
[Id. at 695, 104 S.Ct. at 2068, 80 L.Ed.2d at 698 (citations omitted) (emphasis added).]
The standard for ineffective assistance of counsel under the New Jersey Constitution is the same as the guarantee under the federal constitution.

A.
Defendant contends that he was denied the effective assistance of counsel because of his lawyer’s failure to raise what would have been a meritorious double jeopardy defense. He maintains that the ineffective assistance of counsel claim is separate and distinct from his arguments that he satisfies the good cause exception to the waiver provision of Rule 3:10-2, or that his double jeopardy claim should be reviewed under a plain error analysis.
*285
Generally, ineffective assistance of counsel claims are not entertained on direct appeal “because such claims involve allegations and evidence that lie outside the trial record.”
State v. Preciose,
129
N.J.
451, 460,
As noted earlier, improper termination of a defendant’s trial after jeopardy attaches bars retrial. When a defendant’s mistrial is granted without manifest necessity or the presence of sufficient legal grounds, the termination is improper.

at 435,
*286
The question remains whether the prejudice prong of the
Strickland/Fritz
test for ineffective assistance of counsel has been satisfied here. We have no doubt that it was. Although
Strickland
does state that satisfaction of the prejudice prong requires proof that counsel’s deficient performance deprived defendant of “a fair trial, a trial whose result is reliable,” 466
U.S.
at 687, 104

Case law outside our jurisdiction supports the proposition that a defense attorney’s failure to raise a meritorious double jeopardy defense can be deficient performance on the part of counsel that is prejudicial to a convicted defendant under
Strickland.
In
Wilcox v. McGee,

The Ninth Circuit Court of Appeals held that dismissing the indictment over defendant’s objection precluded further prosecution on the same charges unless the dismissal was required by “manifest necessity.”
Ibid.
The court found that no such necessity existed.
Id.
at 1245. Accordingly, defense counsel’s failure “to move for dismissal of the second indictment on grounds that were both obvious and meritorious,”
id.
at 1246, in conjunction with the absence of a perceived strategy for inaction, was held to be clearly prejudicial to the defendant because it exposed him to a second trial in violation of the Double Jeopardy Clause of the Fifth Amendment.
Ibid.
The “failure to file a motion that would have preserved [the defendant’s] double jeopardy claim, clearly prejudiced [the defendant].”

Defense counsel failed to raise the double jeopardy defense in the armed robbery trial. Ibid. Although the district court held that the defendant procedurally was barred from directly raising a double jeopardy claim, the Fifth Circuit held that defense counsel was ineffective because he failed to raise double jeopardy as a defense at the defendant’s second trial. Id. at 95-96.
The Fifth Circuit held that the defendant satisfied Strickland’s prejudice prong,

noting that “[i]f counsel had asserted the double jeopardy defense, the state court could not have tried [him] for armed robbery. If [the defendant] had not been tried, he obviously would not have been convicted. Thus, the outcome of the trial was vitally affected by counsel’s dereliction.”

Therefore, we conclude that defendant has shown ineffective assistance of counsel due to the failure of counsel to raise the double jeopardy defense after having objected to the existence of sufficient grounds for the grant of a mistrial. Defendant is entitled to reversal of his conviction and dismissal of the second indictment with prejudice.
B.
In view of our disposition of defendant’s ineffective assistance of counsel claim, we need not resolve defendant’s alternative argument concerning the standard of good cause required for relief from the waiver provision of Rule 3:10-2(c). Further, defendant also argued that his double jeopardy claim should be reviewed as a matter of plain error, a contention rejected by the Appellate Division.
Because we have disposed of this appeal in a manner favorable to defendant on other grounds, we need not decide the question of whether plain error occurred. Nor need we reach the related argument that the pretrial motion requirement of
Rule
3:10-2(c) results in a forfeiture, not a waiver, of the double jeopardy claim, and that therefore as a forfeited claim it can be raised as plain error. See
United States v. Olano,
507
U.S.
725, 733-34, 113
S.Ct.
1770, 1777,
The question of defendant’s entitlement to a plain error review is a difficult one. Although our courts have required adherence to the pretrial motion requirement of
Rule
3:10-2, when a double jeopardy claim has been raised on appeal the underlying merits of such claims have not escaped judicial attention. For example, in
Currie, supra,
the defendant raised a double jeopardy claim for the first time on appeal and argued that his prior conviction in Municipal Court for the motor vehicle violations of reckless driv
*291
ing and leaving the scene of an accident barred his subsequent prosecution on the same facts for atrocious assault and battery. 41
N.J.
at 533-34,
Currie
exemplifies a common approach. Notwithstanding noncompliance with
Rule
3:10-2(c), our courts have examined the merits of a claim of double jeopardy.
See, e.g., State v. Ebron, supra,
61
N.J.
at 217,
It has been argued that by analyzing the merits of a double jeopardy claim, a form of plain error review is performed. Gabriel J. Chin,
Double Jeopardy Violations as “Plain Error” Under Federal Rule of Criminal Procedure 52(B),
21
Pepp. L.Rev.
1161, 1210, 1214-15 (1994) (analyzing federal case law and waiver provision of
Fed.R.Crim.P.
12(b); contending that when courts hold that double jeopardy claim is waived but proceed to review merits nonetheless, plain error review is performed). That commentary notes a formidable number of conflicting federal cases on the question whether plain error review is appropriate. Chin,
supra,
21
Pepp. L.Rev.
at 1214-17. Some federal courts have addressed the merits of a defendant’s belated double jeopardy claim, despite the assertion of a waiver.
Id.
at 1209-10.
See also United States v. Moore,
958
F.2d
646, 650 (5th Cir.1992) (noting that even though double jeopardy claim was waived, claim was meritless);
United States v. Becker,
On the other hand, numerous federal decisions have upheld a waiver of double jeopardy and affirmed a judgment without analyzing the merits of the double jeopardy claim. Chin, 21
Pepp. L.Rev., supra,
at 1217 n. 345.
See, e.g., United States v. Papadakis,
We regard the question whether a plain error analysis must occur as far from clear. In any event, in this case we do not intend to create a rule that requires review for ineffective assistance of counsel whenever a lawyer does not interpose a double jeopardy defense in accordance with Rule 3:10-2. Our holding embraces only the facts of this case, in which defense counsel objected to the grant of a mistrial on grounds that rebutted the basis for declaration of the mistrial, but did not explicitly assert the double jeopardy claim prior to retrial. We limit our relief to that context. Notwithstanding the Court’s disposition, Rule 3:10- *294 2 retains vitality. We do not foreclose the possibility that a defendant may waive a double jeopardy claim without implicating Sixth Amendment rights. In future cases involving a retrial following a mistrial, we suggest that the trial court make the waiver of any double jeopardy claim a matter of record to assist in appellate review.
IV.
The judgment of the Appellate Division is reversed. Defendant’s conviction is reversed and his indictment is dismissed. We note that the Appellate Division released defendant on bail pending appeal by Order dated April 11, 2001. The matter is remanded to the Law Division for further proceedings consistent with this opinion.
