OPINION
CRONE, Judge.Terry Rowe appeals the denial of his petition for post-conviction relief for ineffective assistance of counsel. We affirm.
In the fall of 2003, the United Drug Task Force of Hendricks County used a confidential informant to perform three controlled buys of cocaine from Rowe, resulting in two counts of class B felony dealing in cocaine and one count of class A felony dealing in cocaine. There were police video- and audiotapes of the controlled buys. As of July 15, 2004, no plea agreement had been reached. On July 20, 2004, the State's confidential informant died from a drug overdose. Shortly after his death, the State offered Rowe a plea bargain giving him a ten-year sentence, with two years suspended.
Rowe's counsel was not appointed. Despite the fact that she was only recently out of law school and had not previously tried a class A felony case, Rowe hired her to represent him. She showed him a copy of the State's plea offer, and they discussed whether to accept or reject it. She believed that it would be difficult for the State to prove its case without the confidential informant. They discussed the fact that the audiotape was of poor quality and that Rowe's face was not visible on the videotape-only the license plate to his *443car. Rowe's attorney counseled him on whether to accept the plea offer or go to trial. She advised him to reject the plea. This was not Rowe's first exposure to the criminal justice system. He had been arrested previously on drug charges and had also been convicted through plea agreement of burglary and theft, serving time in the Department of Correction.
Rowe rejected the plea agreement, waived his right to a jury trial, and was convicted of class A felony and one count of class B felony dealing in cocaine. On November 4, 2004, the trial court sentenced Rowe to ten years' imprisonment for the class B felony and twenty years' imprisonment for the class A felony, to be served consecutively. On February 6, 2006, Rowe filed a pro se petition for post-conviction relief, which was subsequently amended by counsel. On April 11, 2006, the post-conviction court denied Rowe's amended petition.
On appeal, Rowe alleges that, had he been properly advised that he could be convicted without the testimony of the confidential informant and that he faced a mandatory minimum sentence of twenty years for the class A felony count, he would have accepted the State's plea offer. The post-conviction petitioner has the burden of establishing the grounds for relief by a preponderance of the evidence. Ind. Post-Conviction Rule 1(5). When a petitioner appeals the denial of post-conviction relief, he appeals from a negative judgment. Bahm v. State, 789 N.E.2d 50, 57 (Ind.2002). Consequently, we may not reverse the post-conviction court's judgment unless the petitioner demonstrates that the evidence "as a whole, leads unerringly and unmistakably to a decision opposite that reached by the post-conviction court." Id. We accept the post-conviction court's findings of fact unless they are clearly erroneous, but we do not have to give deference to its conclusions of law. Id. On appeal, we may not reweigh the evidence or reassess the credibility of the witnesses. Id.
Rowe contends that he was denied the effective assistance of trial counsel. We evaluate claims pertaining to the denial of the Sixth Amendment right to effective assistance of counsel using the two-part test articulated in Strickland v. Washington, 466 U.S. 668, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984). To prevail, a defendant must show both that his attorney's performance fell below an objective standard of reasonableness and that the deficiencies in the attorney's performance were prejudicial to the defense. Bahm, 789 N.E.2d at 57-58. An inability to satisfy either prong of this test is fatal to an ineffective assistance claim. Vermillion v. State, 719 N.E.2d 1201, 1208 (Ind.1999). In Lawrence v. State, 464 NE2d 1291 (Ind.1984), the Indiana Supreme Court considered whether trial counsel's erroneous explanation of possible penalties facing the defendant constituted ineffective assistance of counsel when the defendant ultimately rejected a guilty plea offer. The court held that the proper test is "one of reasonableness" and that "perfection" is not required. Id. at 1295.
In the present case, there is evidence in the record to support the post-conviction court's finding that counsel's performance was reasonable, in that her advice to Rowe was merely a prediction of a possible outcome, not an ironclad guarantee. She testified that she told Rowe it would be "very difficult" for the State to prove its case. Tr. at 22. She also testified that she told Rowe that he "should be successful at trial." Id. at 17.1 Additionally, Rowe, who *444was not a novice to the criminal justice system, was aware that he was charged with multiple offenses, including class A felony dealing in cocaine and two counts of class B felony dealing in cocaine. While different interpretations of the record are possible, we cannot say that the post-conviction court's findings of fact and ultimate conclusion on this issue are clearly erroneous.
We also address the State's argument that in order to establish prejudice, Rowe must show that: (1) he would have accepted the plea agreement had he known that there was a possibility of conviction without the confidential informant; and (2) the trial court would have accepted the plea bargain agreement. Appellee's Br. at 12-18 (citing Lessig v. State, 489 N.E.2d 978, 983 (Ind.Ct.App.1986)). In Lessig, this Court declined to find the defendant, who claimed to be innocent, to be prejudiced for rejecting a plea agreement because Indiana does not allow a defendant to enter in Alford plea.2 Without addressing the merits as applied to this case, we note that since Lessig was decided over twenty years ago, no court has reiterated its holding. Because the trial court was precluded by law from accepting his plea agreement, the defendant in Lessig failed to show that the trial court could have accepted his plea, not that the trial court would have accepted his plea. We believe the correct reading of Lessig to be that a defendant must put forth evidence that the trial court is legally permitted to accept his plea agreement.3 In sum, Rowe did not receive ineffective assistance of counsel.
Affirmed.
MAY, J., concurs. BROWN, J., dissents with separate opinion.. The dissent cites evidence that Rowe's counsel told him that he "would" be successful at trial. Op. at 445. We note, however, that counsel acknowledged at the post-conviction *444hearing that she "may" have said "would" and that we must consider only the evidence most favorable to the judgment. Oliver v. State, 843 N.E.2d 581, 587 (Ind.Ct.App.2006), trans. denied.
. In 1970, the U.S. Supreme Court found that the U.S. Constitution did not bar a court from accepting a guilty plea when the defendant maintains innocence. North Carolina v. Alford, 400 U.S. 25, 38, 91 S.Ct. 160, 27 L.Ed.2d 162 (1970). Alford explicitly recognizes, however, that the individual states may refuse to accept guilty pleas that accompany protestations of innocence. Id. Indiana has long refused to accept such pleas. Over fifty years ago, this Court held that "a plea of guilty tendered by one who in the same breath protests his innocence, or declares he does not actually know whether or not he is guilty, is no plea at all." Harshman v. State, 232 Ind. 618, 621, 115 N.E.2d 501, 502 (1953).
. Rowe cites Dew v. State, 843 N.E.2d 556 (Ind.Ct.App.2006), trans. denied, for the proposition that he is required only to prove that he would have accepted the plea agreement, Dew is inapplicable, however, because in that case, the defense counsel completely failed to relay a tendered plea offer to the defendant.
