OPINION
Case Summary
Respondent-Appellant, the State of Indiana (“the State”), appeals from the grant of Petitioner-Appellee’s, Jesse Lopez’s (“Lopez”), petition for postconvietion relief. We reverse in part and affirm in part.
Issues
The State raises one issue for our review, which we restate as:
I. Whether the decision of the postconviction court with regard to Lopez’s sentence is barred by principles of res judicata.
Lopez raises two issues on cross appeal, which we restate as:
II. Whether the State withheld evidence from Lopez and, if so, whether there was a reasonable probability that the outcome of Lopez’s trial would have been different by virtue of that withholding of evidence; and,
III. Whether Lopez received effective assistance of trial and appellate counsel.
*1065 Facts and Procedural History
The postconvietion court vacated а portion of Lopez’s sentence. Lopez was sentenced to a term of forty years for aiding the delivery of cocaine and to a term of four years for dealing in a sawed-off shotgun. Because it found three aggravating circumstances and no mitigating circumstances, the trial court added ten years to the presumptive sentence for dealing in cocaine and added two years to the presumptive sentence for dealing in a sawed-off shotgun. On September 6, 1988, our supreme court affirmed Lopez’s conviction and sentence.
Lopez v. State,
On August 29, 1995, the postconvietion court granted Lopez’s petition for postconviction relief with regard to his sentence. In so doing, the postconvietion court found that there were mitigating circumstances which canceled out the aggravating circumstances found by the trial court. In all other respects, the postconvietion court denied Lopez’s petition for post-conviction relief. Because the trial court on sentencing did not factor in mitigating circumstances, the post-conviction court reduced Lopez’s sentence from 40 years to 30 years on the conviction for dealing in cocaine. The State appeals 1 the reduction in Lopez’s sentence and Lopez appeals the denial оf his petition for postcon-vietion relief on two other issues.
Discussion and Decision
I
We look first to the issue of whether the decision of the postconvietion court with regard to Lopez’s sentence is barred by principles of
res judicata.
The standard of review of a judgment granting postconvietion relief is governed by Indiana Trial Rule 52(A).
State v. Van Cleave,
In reviewing a finding of ineffective assistance, we substantially defer under the “clear error” standard to the trial court’s findings of fact but not to its conclusions of law. A “clearly erroneous” judgment can result from application of the wrong legal standard to properly-found facts, and in that situation we do not defer to the trial court. We are not bound by the trial court’s characterization of its results as “findings of fact” or “conclusions of law.” Rather, we look past these labels to the substance of the judgment and will review a legal conclusion as such even if the judgment wrongly classifies it as a finding of fact.
State v. Van Cleave,
at 1296. The same standard of review applies in this case. Clear error exists because the postconvietion court ignored the rule of
res judicata. Res judicata
operates to bar further litigation where a final judgment on the merits has been rendered on the same claim between the same parties. Lopez argued in his direct appeal that his sentence was manifestly unreasonable because the trial judge did not factor in any mitigating circumstances. The post-conviction process is not a substitute for a direct appeal, but is a process for raising issues not known at the time of the original trial or for some reason not available to the defendant for direct appeal.
Wallace v. State,
Lopez argues that the State is prohibited from asserting the affirmative defense of res judicata in this appeal because it did not assert the defense as required in its respon *1066 sive pleading or at the postconvietion hearing. However, in its response to Lopez’s claim of a manifestly unreasonable sentence in his petition for postconvietion relief, the State pleaded: “That the sentencing of Petitioner was upheld by the Supreme Court in Lopez v. State.” (P.C.Rec. 43). This language was specific enough to alert the court and Lopez under the notice pleading requirement that the State was asserting the affirmative defense of res judicata.
Even if the State had not pleaded the affirmative defense of
res judicata
at all, we would reverse the postconvietion court’s reduction of Lopez’s sentence. Our supreme court held in
Schiro v. State,
The entire record of the trial and the original PCR petition were put into evidence in the instant cause. The trial court had the ability to read the opinion and compare issues, and the power to dismiss these issues disposed of in this court’s prior proceedings. The trial court properly found all four issues were so disposed and there was not error in dismissing them as res judicata.
Id. at 1205.
In
Mickens v. State,
The issue is whether the doctrine of waiver may be asserted on appeal by a petitioner who was granted postconvietion relief, thereby circumventing the doctrine of
res judica-ta.
In essence, when the State can plead
res judicata
on an issue but fails to sufficiently do so, is a postconvietion court afforded the latitude of overruling the prior holding of our supreme court on the issue? We faced this issue once before in
Clark v. State,
However, by distilling the concept of res judicata to its essence, it is clear that review of actions finally determined is barred. This is especially true when the Court of Appeals is asked to rе-review questions finally determined by our supreme court. Our supreme court in Mick-ens,596 N.E.2d at 1381 , determined that the State may persist in alleging waiver and presumably res judicata even if the post-conviction court does not base its decision on those concepts. The State’s failure to somehow preserve the issues cannot allow this Court to engage in the legal fiction that the issues have not been previously determined.
Id. at 1190.
We agree that “at some pоint, whether specifically pleaded by the State or not, a postconvietion petitioner is not entitled to further review of questions finally determined.” Id. at 1191. It is for this reason that we reverse the grant of Lopez’s petition for postconvietion relief with regard to his sentence.
Nonetheless, we hold that Lopez’s sentence of 40 years is not manifestly unreasonable. A sentence is manifestly unreasonable only if no reasonable person could find the sentence appropriate to the particular offense and offender.

Garrison v. State,
II
We turn now to Lopez’s cross-appeal and examine whether the State withheld evidence from Lopez and, if so, whether there was a reasonable probability that the outcome of Lopez’s trial would have been different by virtue of that withholding of evidence. Lopez, as Petitioner at the post-conviction hearing, had the burden of proving he was entitled to relief by a preponderance of the evidenсe. Ind.Post-Convietion Rule 1, § 5;
Smith v. State,
Under
Brady v. Maryland,
First, Lopez did not establish that the existence of suppressed evidence favorable to him. He claims that the prosecution had evidence that someone other than Lopez possessed shotgun shells at the time of the arrest. Lopez asserts that the shotgun shells were relied upon by the jury to connect him to the crime. He presented evidence in the form of the testimony of the former prosecutor, Nancy Vaidik (“Vaidik”). Vaidik, based on ten-year-old recollections, called into doubt to whom the shotgun shell could be attributed. Her recollections consisted of hearsay statements about the various officers’ statements regarding the shotgun shells. The officers did not testify at the postconviction hearing. At trial, one officer attributed the shotgun shell to Lopez. Lopez failed to demonstrate what evidence the other officers would have provided at trial and why such evidence would be material to the outcome of the case.
Second, the postconvietion court properly found that even assuming the State pos *1068 sessed evidence favorable to Lopez, its existence- would not require a new trial. The arrеsting officer testified that he found the shotgun shells on Lopez. The two officers about whom Vaidik testified were not the arresting officers. They did not conduct a search of Lopez’s person and nor were they in the area when the arresting officer conducted the search of Lopez and found the shells. Accordingly, we affirm the postcon-viction court’s denial of posteonviction relief on this issue.
Ill
Next, we determine whether Lopez received effective assistance of trial and appellate counsel. In essence, Lopez claims his attorneys, who represented him at trial and on appeal, did not meet the requirements of the two-part test announced in
Strickland v. Washington,
First, Lopez must make a showing that the performance of his counsel was deficient. “Judicial scrutiny of counsel’s performance is highly deferential and should not be exercisеd through distortions of hindsight. Counsel is presumed competent, and appellant must present strong and convincing evidence to rebut the presumption.”
Clark v. State,
Lopez alleges trial counsel: (1) failed to interview all of the police officers involved in the drug transaction and to uncover material statements by certain police officers concerning certain shotgun shells; (2) failed to conduct any financial analysis of Lopеz’s finances; (3) failed to properly explore and prepare for the testimony of Mr. Rodriguez, a codefendant and key witness for the State; and (4) failed to involve Lopez in trial preparation or strategy or to keep him informed of the progress of the defense.
We note first that the issue of whether Lopez received effective assistance of trial counsel was visited by our supreme court in Lopez’s direct appeal and pleaded by the State in its response to Lopez’s petition. He is barred by res judicata from asserting the issue now. Second, any issues relating to the effectiveness of trial counsel not raised in Lopez’s direct appeal are barred in this appeal due to his waiver of those issues. Third, we also reject Lopez’s arguments as to the effectiveness of trial counsel with regard to the evidence of the shotgun shells because his Brady claim failed. Lopez did not prove there was material evidence which by a preponderance of the evidence would reasonably be taken to put the whole case in such a different light as to undermine confidence in the verdict. His trial counsel was not ineffective because there was no such material evidence.
We turn finally to Lopez’s claim of ineffective assistance of appellate counsel. 2 Lopez argues his appellate counsel was ineffective for the following: (1) failure to include in the record of proceedings a tape recording of a statement made by Mr. Rodriguez before trial exonerating Lopez; (2) failure to interview, depose, or otherwise obtain a statement from trial counsel concerning the ineffective assistance of trial counsel claim; (3) failure to utilize the Davis/Hatton procedure to develop the record for appeal; (4) failure to enumerate mitigating circumstances; and (5) failure to conduct research on the standard of “manifestly unreasonable” sentencing or to provide argument or explanation why Lopez’s sentence was manifestly unreasonable.
*1069
Because Lopez received effective assistance of trial counsel, appellate counsel was not ineffective for failing to address putative shortcomings of trial counsel. Therefore, Lopez’s second, fourth, and fifth claims of ineffective assistance of appellate counsel summarily fail. Likewise, Lopez’s third claim of ineffective assistance of appellate counsel fails because the
Davis/Hatton
procedure involves a termination or suspension of a direct appеal already initiated, upon appellate counsel’s motion for remand or stay, to allow a posteonviction relief petition to be pursued in the trial court.
Davis v. State,
Reversed, in part, and remanded to the posteonviction court to reinstate Lopez’s sentence as imposed by the trial court and upheld by our supreme court; affirmed, in part, on the issues presented on Lopez’s cross-appeal.
Notes
. In preparing their briefs, practitioners are to follow the rules set out in the current Uniform System of Citation (Bluebook). Ind.Appellate Rule 8.2(B). Practitioner's Note 2 of the Blue-book provides: "Citations in court documents and legal memoranda may be made in either of two ways: in citation sentences or in citation clauses....” Note 2 also states that these citations to authority are to “immediately follow the proposition they support (or contradict).” The example within Practitioner’s Note 2 is illustrative. Citations should continue to appear in the text or body of appellate briefs. The only exception arises when supplemental information appears in a footnote. Then, a citation to authority for that supplemental information is appropriately included in that same footnоte.
