MOELLER, Justice
Jeffrey Marsalis appeals the Blaine County district court’s decision summarily dismissing his petition for post

- conviction relief from his 200 9 rape conviction

. In his petition, Marsalis alleged that his trial counsel was ineffective for failing to (1) challenge the testimony of the State’ s expert witness regarding his and the victim’s blood alcohol levels , (2) present favorable eyewitness testimony at trial , and (3) properly advise him of his speedy trial rights under the Interstate Agreement on Detainers (IAD)

. The district court summarily dismiss ed each of Marsalis’s claims. The Court of Appeals reversed in part a nd affirmed in part. The State petition ed this Court for review , which we granted. For the reasons stated below, w e reverse in part and affirm in part the district court’s decisio n

.2 I. FACTUAL AND PROCEDURAL BACKGROUND On O ctober 8 , 2005, Marsalis and K.G. , who were acquainted through their work in Sun Valley , went out for drink s at a bar in Ketchum

. Testimony from the bartender established that Marsalis ordered a total of twenty b eers and four shots for the two of them, and that K.G. also

o rdered a few beers for herself. All of the drinks were placed on Marsalis’s tab. Following several hours of drinking, Marsalis and K.G. took a shuttle back to Marsalis’s condominium in Sun Valle y . The driver of the shuttle and a passenger both testified that K.G.

was “ drunk, ” almost passed out d uring the ride back to Sun Valley , and had difficulty walking while entering and exiting the shuttle

. K.G. testified that she had no recollection of when she left the bar or how she ended up at Marsalis’s reside nce

. U pon waking later that morning , K.G. explained that she did not know where she was , but saw that Marsalis was in the bed next to her. K.G. also testified that she vomited sever al times that morn ing , experienced pa in when urinating , and felt “bruised” in her vaginal area

. Later that night, K.G. reported to the Ketchum Police Department that she thought Marsalis had raped her

. She also reported observing a grainy substance on the bottom of one of her shot glasses while at the bar with Marsalis

. K.G. went to the hospital to have samples of her blood and urine taken. Marsalis was interviewed by the police and denied having sexual relations with K.G. , but was nevertheless arrested for rape. The sample s ultimately showed the presence of Marsalis’s semen. However, l ater testing failed to show the presence of any foreign substances that could have incapacitated K.G. , beside s the alcohol she had consumed

. On April 21, 2006, a grand jury indicted Marsalis o n one count of rape. The indictment alleged that the rape occurred: “ [A]t a time when K.G. was unable to resist due to an intoxicating substance, and/or anesthetic substance; and/or at a time when K.G. was unconscious and/or asleep and/or not aware, knowin g, perceiving, or c ognizant that the act occurred. Idaho Code §§ 18

- 6101 and 6104. ” While released on bail , Marsalis was convicted in Pennsylvania of a separate and unrelated sex offense. While he was housed in the Pennsylvania Department of Corrections, t he Blaine County prosecutor filed a request for temporary custody of Marsalis pursuant to the Interstate Agreement on D etainers (IAD). Marsalis was returned to Idaho on August 18, 2008, and appeared in court the next day.3 After a few continuances and a cha nge of venue to Ada County , t he matter proceeded to trial on April 20, 2009

. Marsalis’s defense at trial was that K

. G

. consented to sexual intercourse with him on the night in question, but could not remember it because she had blacked out. A jury ultimate ly convicted Marsalis of rape. The district court sentenced Marsalis to an indeterminate life sentence with a mandatory minimum of fifteen years to run consecutive to the Pennsylvania

sentence

. Marsalis directly appealed his conviction, which was affirmed by the Court of Appeals.
See State v. Marsalis , 151 Idaho 872, 264 P.3d 979 (Ct. App. 2011). Marsalis filed a timely petit ion for post

- conviction relief

. In his petition, Marsalis alleged that he was denied the right to testify 1 and the right to the effect ive assistance of counsel as
gua ranteed by th e Sixth Amendment to the U.S. Constitution. In his first sub

- claim of ineffective assistance of counsel , Marsalis alleged that his trial counsel was ineffective for failing to challenge the testimony of Dr. Marc LeBeau , the State’s expert witness, regarding his and K.G

. ’s blood alcohol levels. In his second sub

- c laim, Marsalis alleged that his trial counsel was ineffect ive for failing to call a favorable eye witness at trial

. In his final sub

- claim, Marsalis alleg ed that his trial counsel was ineffective f or failing to advise him of his speedy trial rights under the I AD

. The State moved for summary dismissal of Marsalis’s pet ition , which the district court granted

. Marsalis appealed the district court’ s summary dis missal of his petition

. The Court of Appeals affirmed the district court’s dismissal of Marsalis’s second sub

- claim of ineffective assistance of counsel, i.e. , that trial counsel was ineffective for failing to call a favorable
eye witness . However, it rever sed and remanded the district court’s dismissal of Mars alis’s two remaining sub

- claims , i.e. , that trial counsel was ineffective for failing to challenge Dr. LeBeau ’s testimony and for failing to inform Marsalis of his speedy trial rights under the IAD

. Th e State timely petitioned this Court fo r review , which w e granted.
II. STANDARD OF REVIEW “When reviewing a case on petition for review from the Court of Appeals this Court gives due consideration to the decision reached by the Court of Appeals, but directly reviews the decision of the trial court.” State v. Chernobieff , 161 Idaho 537, 539, 387 P.3d 790, 792 (2016) (quoting State v. Lute , 150 Idaho 837, 839, 252 P.3d 1255, 1257 (2011)). “This Court is not merely reviewing the correctness of the Court of Appeal s’ decision; rather, this Court is hearing

1 Marsalis subsequently withdrew this claim.4 the matter as if the case were on direct appeal from the trial judge’s decision.” Gilpin

- Grubb v. State , 138 Idaho 76, 79, 57 P.3d 787, 790 (2002). A petition for post

- conviction relief is civil in nature. “ Like a p laintiff in a civil action, the applicant for post

- conviction relief must prove by a preponderance of evidence the allegations upon which the application for post

- conviction relief is based. ” Charboneau v. State , 144 Idaho 900, 903, 174 P.3d 870, 873 (2 007). Yet u nlike the complaint in an ordinary civil action, a petition for post

- conviction relief must contain more than “a short and plain statement of the claim” that would suffic e for a complaint under Idaho Rule of Civil Procedure 8(a)(2 ). Id. The peti tion “must present or be accompanied by admissible evidence supporting its allegations, or the application will be subject to dismissal.” State v. Yakovac , 145 Idaho 437, 444, 180 P.3d 476, 483 (2008) (citing I.C. § 19

- 4903). Idaho Code section 19

- 4906 aut horizes summary dismissal of a petition for post

conviction relief, “either pursuant to motion of a party or upon the trial court’s own initiative.” Id. “ Summary disposition of a petition for post

- conviction relief is appropriate if the applicant’ s evidenc e raises no genuine issue of material fact.” Charboneau , 144 Idaho at 903, 174 P.3d at 873 (citing I.C. § 19

- 4906(b), (c)). On review of a dismissal of a post

- conviction relief application without an evidentiary hearing, this Court will determine whether a genuine issue of fact exists based on the pleadings, depositions and admissions together with any affidavits on file and will liberally construe the facts and reasonable inferences in favor of the non

- moving party. A court is re quired to accept the petit ioner’ s unrebutted allegations as true, but need not accept the petitioner’ s conclusions. When the alleged facts, even if true, would not entitle the applicant to relief, the trial court may dismiss the application without holding an evidentiary hearing. A llegations contained in the application are insufficient for the granting of relief when (1) they are clearly disproved by the record of the original proceedings, or (2) do not justify relief as a matter of law. Id. (internal citations omitted). III. ANALYSIS O n appeal, a ll of Marsalis’s claims involve allegations of ineffective assistance of counsel. “The right to counsel in c riminal actions brought by the s tate of Idaho is guaranteed by the Sixth Amendment to the United States Constitution and Article 1, Secti on 13 of the Idaho State Constitution.” Dunlap v. State , 159 Idaho 280, 295, 360 P.3d 289, 304 (2015) (quoting Murray v. State , 156 Idaho 159, 164, 321 P.3d 709, 714 (2014)). “[T]he right to counsel is the right to the effective assistance of counsel.” Id. (quoting Murray , 156 Idaho at 164, 321 P.3d at5 714). This Court analyzes claims for ineffective assistance of counsel under the two

- prong test set forth in Strickland v. Washington , 466 U.S. 668, 687 (1984). “To prevail under Strickland , the petitioner mu st show: (1) ‘that counsel’s performance was deficient,’ and (2) ‘that the deficient performance prejudiced the defense.’ ” Dunlap , 159 Idaho at 296, 360 P.3d at 305 (quoting Strickland , 466 U.S. at 687). For the first prong of the Strickland test , the pe titioner must show that “ counsel’s
p erformance fell below an objective standard of reasonableness.” Yakovac , 145 Idaho at 444, 180 P.3d at 483 (citing Strickland , 466 U.S. at 68 7

– 8 8). “[T]his Court does not second

- guess strategic and tactical decision s , an d such decisions cannot serve as a basis for post

- conviction relief unless the decision is shown to have resulted from inadequate preparation, ignorance of the relevant law or other shortcomings capable of objective review.” Id. “There is a strong presumpt ion that counsel’s performance was within the range of acceptability, particularly as to things like defense counsel’s choice of witnesses, manner of cross

- examination, and lack of objections to testimony, which are generally considered to fall within the realm of tactical or strategic decisions.” Thumm v. State , 165 Idaho 405, ___, 447 P.3d 853, 861 (2019).
For the second prong of the Strickland test, the petitioner must show “ a reasonable probability that the outcome of trial would be different but for c ounsel’s deficient performance. ” McKay v. State , 148 Idaho 567, 570, 225 P.3d 700, 703 (2010). “A reasonable probability is a probability sufficient to undermine confidence in the outcome.” Id. (quoting Strickland , 466 U.S. at 694 )

. “The likelihood of a di fferent result must be substantial, not just conceivable.” Adamcik v. State , 163 Idaho 114, 123, 408 P.3d 474, 483 (2017) (quoting Harrington v. Richter , 562 U.S. 86, 112 (2011)). Therefore, “[i]n order to survive a motion for summary dismissal, post

- conv iction relief claims based upon ineffective assist ance of counsel must establish ‘ the existence of material issues of fact as to ’ ” both Strickland prongs. State v. Dunlap , 155 Idaho 345, 383, 313 P.3d 1, 39 (2013) (quoting Kelly v. State , 149 Idaho 517, 5 22, 236 P.3d 1277, 1282 (2010) ). A. Failure to Challenge the Testimony of the State’s Expert Witness e s . Dr. Marc LeBeau , the Unit Chief for the FBI laboratory in Quantico, Virginia, testified for the State regarding Marsalis’s and K.G.’s blood alcohol level s on the night of the incident.
Dr. LeBeau did so by means of “ retrograde extrapolation. ” Using the “ Widmark formula, ” Dr.
LeBeau estimated that K.G.’s blood alcohol level at the time Marsalis and K.G. likely had sexual6 intercourse was 0 .28. Dr. LeBeau the n testified that according to the “ Dubowski chart, ” K.G. would have been in a state of “stupor ” with that blood alcohol level, which is associated with a loss of motor function, reduced response to stimuli , inability to stand or walk, vomiting, and , most i mportantly, impaired consciousness. Usin g the same process, Dr. LeBeau estimated that Marsalis’s blood alcohol level was 0 .16 and that according to the Dubowski chart , he would have been in a state of “excitemen t,” which is associated with a loss of judgme nt and some memory impairment

. Dr. LeBeau ’s testimony supported the State’s allegation that Marsalis had sexual inte rcourse wi th K.G. when she was unconscious due to her excessive alcohol consumption.
In his petition , Marsalis arg ued that trial counsel wa s ineffective for failin g to challenge
Dr. LeBeau ’s testimony

. According to Marsalis, tri al counsel shou ld have challenged Dr.
LeBeau ’s testimony under Idaho Rule of Evidence 702 because “[t]here is no Idaho authority finding the Dubows ki chart sufficientl y reliable ” and “estimation of blood alcohol levels using the Widmark formula is not scientifically reliable,” especially without a known blood alcohol test result to use as a baseline . Additionally, he argued that such evidence was unfairly prejudicial un der Idaho Rule of Evidence 403

. H ad Dr. LeBeau ’s testimon y been admitted over a pretrial objection, Marsalis argued that trial counsel should have retained an expert witness to rebut Dr. LeBeau ’s testimony at trial . Marsalis also argued that trial counsel should have retained an expert witness to explain the scien tific basis behind Marsalis’ s blackout defense , i.e. , that K.G. was conscious when she consented to and willingly participated in the sexual intercourse , but does not remember because she blacked o ut

. In support of his claim, Marsalis presented the affidavits of two experts, Drs. D. Timothy Anstine and Kim Fromme

. Marsalis argued th at had trial counsel done any of these things, the outcome of the trial would have been different. The district court summarily dismissed Marsalis’s claim b ecause it found that trial counsel was not deficient for failing to object to Dr. LeBeau ’s testimony prior to trial or for failing to retain an expert witness to rebut Dr. LeBeau ’s testimony at trial . T he court found t hat an objection to the testimony under Rule 702 would have been overruled because Dr. LeBeau is an expert and “[i]t is clearly within sound trial strategy to not attack an expert who is in fact an expert” and “the substance of Dr. LeBeau’s testimony is no t sufficiently in question.” Similarly, the court found that an objection under Rule 403 would have been overruled because the probative value of the evidence was high and outweighed any risk of unfair prejudice to Marsalis

. The district court also found t hat trial counsel was not deficient for failing to retain an7 expert witness to rebut Dr. LeBeau ’s testimony at trial because trial counsel sufficiently cross

examined Dr. LeBeau

. On appeal, Marsalis contend s that, although the district court acknowledged h is Rule 702 argument in its decision, it incorrectly interpreted his argument as challenging Dr. LeBeau as an expert in general. The actual claim

— that Dr. LeBeau ’s testimony regarding the Wi d mark formula and the Dubowski chart should have been excluded und er Rule 702 because both are scientifically unreliable and speculative

— was not addressed by the district court , nor were the affidavits of Drs. Anstine and Fromme

. In other words, Marsalis’s Rule 702 argument was not based on Dr. LeBeau ’s qualifications, b ut rather on the underlying methodolog ies that formed the basis of his trial testimony. Marsalis also contend s that trial counsel’s cross

- examination was insufficient beca use the jury did not learn that the Widmark formula a nd the Dubowski chart are comple te speculation , and did not learn of the scientific basis behind Marsalis’s blackou t defense

. i. T here is a genuine issue of material fact whether trial counsel was ineffective for failing to challenge Dr. LeBeau ’s testimony prior to trial

. Initially , we ho ld that the record supports Marsalis’s claim that the district court did not accurately perceive the nature of his Rule 702 argument

. In his petition, Marsalis argued that Dr.
LeBeau ’s testimony reg arding his and K.G.’s respective blood alcohol levels “ sho uld not ha ve been admitted under I.R.E. 702 because estimation of blood alcohol levels using the Widmark formula is not scientifically reliable

. ” In support of his claim, Marsalis submitted the affidavits of Drs. Anstine and Fromme . Without any reference t o either affidavit , the district court summarily dismissed Marsalis’s claim because it found that “[i]t is clearly within sound trial strategy to not attack an expert who is in fact an expert.” It is apparent that t he district court misunderstood Marsalis’ s claim as an attack on Dr. LeBeau ’s status as an expert in general when Marsalis’s actual claim was an attack on the reliability of Dr. LeBeau ’s underlying methodologies. When reviewed in the light most favorable to Marsalis, the affidavits of Drs. Anstin e and Fromme call into question the methodologies supporting Dr. LeBeau ’s testimony and potentially undermine the State’s theory of the case. Accordingly, we hold that there is an issue of material fact as to whether Dr. LeBeau ’s testimony was based on rel iable scientific methodologies. As mentioned above, in order to prevail on an ineffectiv e assistance of counsel claim , the petitioner must prove both prongs of the Strickland test , i.e. , deficient performance and prejudice. “Where the alleged deficiency i s counsel’s failure to file a motion, a conclusion that8 the motion, if pursued, would not have been granted by the trial court, is generally determinative of both prongs of the [ Strickland ] test.” Thumm , 165 Idaho at ___, 447 P.3d at 861

– 62 (quoting Dunlap , 155 Idaho at 385, 313 P.3d at 41). Thus, the initial inquiry is whe ther a pretrial motion , had it been made, would have been denied. A motion that would have been denied by the trial court ends the inquiry. I f the motion should have b een granted, however , “the petitioner is still required to overcome the presumption that the decision not to file the motion ‘was within the wide range of permissible discretion and trial strategy .’ ” Id. at 861 (emphasis added) (quoting Estrada v. State , 143 Idaho 558, 561, 149 P.3d 833, 836 (2006)). As suggested above, the initial inquiry is whether a pretrial motion, had it been made by trial counsel , would have been denied by the district court

. The admissibility of expert testimony is governed by Rule 702, which provide s, [a] witness who is qualified as an expert by knowledge, skill, experience, training, or education may testify in the form of an opinion or otherwise if the expert’s scientific, technical, or other specialized knowledge will help the trier of fact to
un derstand the evidence or to determine a fact in issue. “[E]xpert opinion which is speculative, conclusory, or unsubstantiated by facts in the record is of no assistance to the jury in rendering its verdict, and therefore is inadmissible.” Coombs v.
Curnow , 148 Idaho 129, 140, 219 P.3d 453, 464 (2009) (quoting Ryan v. Beisner , 123 Idaho 42, 46

– 47, 844 P.2d 24, 28

– 29 (Ct. App. 1992)). “Testimony is speculative when it ‘theoriz[es] about a matter as to which evidence is not sufficient for certain knowledge.’ ” Id. (quoting Karlson v. Harris , 140 Idaho 561, 565, 97 P.3d 428, 432 (2004)). “In determining whether expert testimony is admissible, a court must evaluate ‘the expert’s ability to explain pertinent scientific principles and to apply those principles to t he formulation of his or her opinion. ’ ” Id. (quoting Ryan , 123 Idaho at 46, 844 P.2d at 28 ). Therefore, admissibility “depends on the validity of the expert’s reasoning and methodology, rather than his or her ultimate conclusion.” Id. Here, Marsalis cont ends that Dr. LeBeau ’s estimation of his and K.G.’s blood alcohol levels through retrograde extrapolation based on the Widmark formula should not have been admitted

. He asserts that determining blood alcohol levels using the Widmark formula is scientifical ly unreliable and speculative under Rule 702 , especially when there is no known blood alcohol test result to use as a baseline , as was the case here

. Marsalis also contends that the Dubowski chart should not have been admitted under Rule 702 because it, to o, is scientifically unreliable

.9 “Retrograde extrapolation” is the “mathematical calculation used to estimate a person’s blood alcohol level at a particular point in time by working backward from the time the blood [sample] was taken.” State v. Dist. Ct. (Armstrong) , 267 P.3d 777, 780 (Nev. 2011) (quoting
Com. v . Senior , 744 N.E.2d 614, 619 ( Mass. 2001)) ; see also State v. Sutliff , 97 Idaho 523, 524 n.1, 547 P.2d 1128, 1129 n.1 (1976) (“The term extrapolation designates the process of determining the perce ntage of alcohol in the blood at a given number of hours prior to the time the sample was taken.”)

. The Texas Court of Criminal Appeals provided a straightforward explanation of the metabolic principles utilized in estimating a person’s blood alcohol level : As alcohol is consumed, it passes from the stomach and intestines into the blood, a process referred to as absorption. When the alcohol reaches the brain and nervous system, the characteristic signs of intoxication begin to show. The length of time nece ssary for the alcohol to be absorbed depends on a variety of factors, including the presence and type of food in the stomach, the person’s gender, the person’s weight, the person’s age, the person’s mental state, the drinking pattern, the type of beverage consumed, the amount consumed, and the time period of alcohol consumption. At some point after drinking has ceased, the person’ s BAC will reach a peak. After the peak, the BAC will begin to fall as alcohol is eliminated from the person’s body. The body eli minates alcohol through the liver at a slow but consistent rate. Mata v. State , 46 S.W.3d 902, 909 (Tex. Crim. App. 2001) (internal citations omitted). “In 1932, Swedish chemist E.M.P. Widmark first calculated absorption and elimination rates in the bod y, and his work still represents the benchmark for other scientists’ studies today.” Id. “Widmark created what we know today as the ‘BAC curve,’ which represents the rise and fall of an individual’s BAC as his body absorbs and eliminates alcohol.” Id. In t he 1970 s , K urt M. Dubowski, Ph.D. , developed a chart that , as explained by Dr. Anstine , “attempts to correlate the clinical signs and symptoms caused by ethanol’s effects on the central nervous system.” Dr. Dubowski classified these effects into stages of acute alcoholic influence/intoxication. Only a f ew jurisdictions have evaluated the reliabil ity of retrograde extrapolation , Idaho not being one of them. 2 In the jurisdictions that have considered it , most have held that retrograde extrapolation is a gener ally accepted scientific method , but only when it is applied correctly

. See, e.g. , State ex. rel. Montgomery v. Miller , 3 2 1 P.3d 454, 469 (Ariz. Ct. App. 2014)

2 This Court has only address ed the r elevancy of retrograde extrapolation , not its reliability

. See State v. Austin , 163 Idaho 378, 381

– 82, 413 P.3d 778, 781

– 82 (2018); State v. Robinett , 141 Idaho 110, 112

– 13, 106 P.3d 436, 438

– 39 (2005); State v. Daniel , 132 Idaho 701, 703, 979 P.2d 103, 105 (1999), abrogated on other grounds by Verska v. Saint Alphonsus Reg’l Med. Ctr. , 151 Idaho 889, 265 P.3d 502 (2011); Sutliff , 97 Idaho at 525, 547 P.2d at 1130.10 (“[R]etrograde analysis is generally considered to be a reliable scientific discipline.”); State v. Vliet , 19 P.3d 42, 60 (Haw. 2001) (“We take judicial notice that Widmark’s formula is widely viewed as reliable.”); State v. Day , 176 P.3d 1091, 1099 (N.M. 2008) (“[T]he State can use scientific retrograde extrapolation evidence to prove that a BAC tes t taken after three hours and below 0.08 shows that the defendant had an actual BAC of 0.08 or higher within three hours of driving.”); State v. Davis , 542 S.E.2d 236, 241 (N.C. App. 2001 ) (“ We have accepted the reliability of extrapolation evidence since 1985 .”); State v. Trujillo , 353 P.3d 609, 617 (Or. App. 201 5) (“[We] conclude generally that retrograde extrapolation using the Widmark formula is scientifically valid.”); Bigon v. State , 252 S.W.3d 360, 367 (Tex. Crim. App. 2008) (“[T]hough there is some disagreement in the scientific community, retrograde extrapolation can be rel iable when applied correctly.”).
To challen g e the reliability of retrograde extrapolation as applied in this case , Marsalis presented the affida vits of Drs. Anstine and Fromme

. R egarding the Widmark formula, Dr. Anstine, an expert on chemical testing, opined that, although the Widmark form ula is generally accepted in blood alcohol concentration estimations and “gi ves very precise calculations , it does not automatically lead to acc urate valu es.” Dr. Anstine explained: The scientific assessment of an individual’s actual BAC is very complex due to the wide range of both psychological and biochemical parameters unique to every individual. For this reason, it is not good scientific pra ctice to rely too heavily on any single technique. To establish the most accur ate assessment of an individual’ s actual BAC and its corresponding effects, it is best to look at multiple overlapping, yet still highly subjective techniques. The use of blood o r breath analysis in concert with Widmark calculations helps establish a more accurate BAC and the level of intoxication. When describing the issues in this particul ar case, Dr. Anstine explained: [T]he state did not have blood or breath analysis, nor di d it have any video or audio files. To my knowledge the State relied solely on Dr. LeBeau’s Widmark calculations that he based off a bar tab and eye witnesses to establish a possible level of intoxication for both Mr. Marsalis and [K.G.]

. . . Dr. Anstine also acknowledged that Dubowski himself wrote that “it becomes clear that the speculative retrograde extrapolation of the BAC to any point from an experimentally determined value must be avoided in forensic practice, or so qualified by state d assumptions t hat the exercise becomes pointless.” See Dubowski, K.M., Alcohol Technical Reports , 1976, 5:55

- 63

. Regarding the Dubowski chart, Dr. Anstine opined that “[g]reat caution must be used in assessing a[n] individual[’]s ‘stage of alcoholic influence,’ as each individual is very unique and11 how different individuals are affected by alcohol has enormous ranges of influence.” Rather, “[t]he use of eye

- witness accounts along with any available video or audio files of the individual in concert with the Dubowski char ts helps establish the influence of the level of intoxication.” Dr. Anstine concluded that “the State relied too heavily on one single technique, specifically the Widmark formula, and from these speculative calculations made sweeping assumptions, based

on the Dubowski chart, concerning the levels of intoxication and its influence on Mr. Ma rsalis and [K.G.]

. ” Without knowing Marsalis ’s and K.G.’s specific level s of intoxication at any point in time , “ any discussion concerning the ‘stages of alcoholic influen ce’ is complete speculation.”
Dr. Fromme , a professor of clinical psychology and a specialist in alcohol

- induced blackouts , similarly described the problems with Dr. LeBeau ’s reliance on the Widmark formula and the Dubowski chart : [T]here is no basis for t he specific signs and symptoms associated with the BAC levels in the Dubowski chart. In addition, the BAC levels in each category are so large that they are not useful for any given person. The lower and upper limits differ by an average of .15 g% BAC; whi ch is a large difference in drinking quantity. Most importantly, I have not been able to find any scientific basis for the signs and symptoms attributed to the categories of BAC in the Dubowski chart. Based on the affi davits of Drs. Anstine and Fromme , w ha t appears to be the bigger issue in this case is that Dr. LeBeau attempted t o make a retrograde extr apolation of blood alcohol levels without a known blood alcohol test result to use as a baseline

. This key fact distinguishes this case from the cases cited above that found retrograde extrapolation admissible

. In each of those cases

— all of which involv ed driving under the influence

— the expert was performing retrograde extrapolation with the benefit of a known alcohol level from a breath or blood test taken s ometime after the individual was pulled over. T he expert then relate d the known alcohol level back to the time when the individual was driving

. In Mata , the Texas Court of Criminal Appeals ex plained , [t] he court evaluating the reliability of a retrograde extrapolation should also consider (a) the length of time between the offense and the test(s) administered; (b) the number of tests given and the length of time between each test ; and (c) whether, and if so, to what extent, any individual characteristics o f the defendant were known to the expert in providing his extrapolation. These characteristics and behaviors might include, but are not limited to, the person’s weight and gender, the person’ s typical drinking pattern and tolerance for alcohol, how much th e person had to drink on the day or night in question, what the person drank, the duration of the drinking spree, the time of the last drink, and how much and what the person had to eat either before, during, or after the drinking.12 46 S.W.3d at 916 (emphas is added)

. In this case, n o chemical testing of the blood or breath was ever done on Marsalis or K.G. to determine the ir alcohol levels at the time in question

. Therefore, Dr. LeBeau had to rely solely

on Marsalis ’s and K.G.’s physical characteristics , wi tness accounts of their behavior, and a bar tab to determine the likely num ber of beverages consumed

. Based on this difference alone , we hold that there is a genuine issue of material fact as to whether a motion to exclude Dr. LeBeau ’s testimony w ould have been granted by the district court

. The next inquiry , then, is whether trial counsel’s decision to not pursue a pretrial motion

was a st rategic decision. We hold that i t was not. “[T]his Court does not second

- guess strategic and tactical decision s , and s uch decisions cannot serve as a basis for post

- conviction relief unless the decision is shown to have resulted from inadequate preparation, ignorance of the relevant law or other shortcomings capable of objective review.” Yakovac , 145 Idaho at 444, 180 P.3 d at 483. In this case, t here is no con ceivable strategic justification for trial counsel’s failure to pursue a pretrial motion to exclude Dr. LeBeau ’s testimony , especially because trial counsel barely questioned Dr. LeBeau during cross

- examination , there by leaving the jury with Dr. LeBeau ’s mostly unrebutted testimony. On the other hand, h ad trial counsel filed a pretrial motion to exclude Dr. LeBeau ’s testimony , and had the district court granted t he motion, Dr. LeBeau ’s testimony would have been exclude d and the only evidence the jury would have had to determine K.G.’s level of intoxication was (1) a bar tab providing the probable number of beverages consumed , (2) K.G’s testimony describing the night of the incident and her symptoms, (3) Marsalis’s state ments describing the night of the incident, and (4) ey ewitness testimony from the shuttle ride back to Sun Valley. Th us, there is a genuine issue of material fact as to whether trial counsel was de ficient for failing to challenge the scientific basis for D r. LeBeau ’s testimony prior to trial. Under Strickland , t he final inquiry is whether trial counsel’s alleged deficiency prejudiced Marsalis. See Baldwin v. State , 145 Idaho 148, 157, 177 P.3d 362, 371 (2008) (requiring the petitioner to prove both deficien cy and prejudice when asse rting trial counsel was ineffective for failing to file a motion). In order to prove prejudice, Marsalis must show that there is “a reasonable probability that the outcome of trial would be different but for counsel’s deficient pe rformance.” McKay , 148 Idaho at 570, 225 P.3d at 703

. A reasonable probability means “a probability sufficient to undermine confidence in the outcome.” Id

. (quoting13 Strickland , 466 U.S. at 694). In his petition, Marsalis argued that he was prejudiced by tr ial counsel’s deficiency because there is a reasonable probability that the jury would have acquitted him absent Dr. LeBeau ’s testimony. Marsalis’s argument has some merit. It was the State’s burden to prove beyond a reasonable doubt that K.G. was unconsci ous or too intoxicated to consent to sexual intercourse with Marsalis. W ithout an expert opining that K.G. was likely unconscious when Marsalis had sexual intercourse with her because she had a n estimated blood al cohol level of 0.28 , there is a genuine iss ue of material fact as to whether the outcome of the trial would have been different.
In sum , there is a material question of fact as to whether trial counsel was deficient for failing to challenge Dr. LeBeau ’ s testimony prior to trial , and as to whether t h ere is a reasonable probability of a different result had Dr. LeBeau ’s testimony been challenged and excluded

. Therefore, the district court erred in granting summary dismissal without affording Marsalis an evidentiary hearing.
ii. T here is a genui ne issue of material fact whether trial counsel was ineffective for failing to retain an expert witness to rebut Dr. LeBeau ’s testimony at trial and to explain the scientific basis behind Marsalis’s blackout defense

. Marsalis argue s that, had Dr. LeBeau ’s testimony b een admitted over objection, trial counsel should have reta ined an expert witness to rebut his testimony at trial and was ineffective for failing to do so

. This is not merely a hypothetical concern because Dr. LeBeau did in fact testify at trial. Marsalis also argue s that trial counsel should have retained an expert witness to explain th e scientific basis behind his blackout defense

. According to Marsalis, had the jury heard that Dr. LeBeau ’s conclusions were derived from unreliable methods , and had the jur y heard about blackouts and their causes and effects , there is a reasonable probability that the jury would have acquitted him. We hold that there is an issue of material fact as to whether trial counsel was ineffective for failing to retain an expert to a ddress these matters. “The decision of what witnesses to call ‘is an area where we will not second guess counsel without evidence of inadequate preparation, ignorance of the relevant law, or other shortcomings capable of objective evaluation.’ ” State v. P ayne , 146 Idaho 548, 563, 199 P.3d 123, 138 (2008) (quoting State v. Larkin , 102 Idaho 231, 234, 628 P.2d 1065, 1068 (1981)). To justify an evidentiary hearing in a post

- conviction relief proceeding, it is incumbent on the applicant to tender written stat ements from potential witnesses who are able to give testimony themselves as to facts within their knowledge. It is not enough to simply allege that an expert should have been14 secured without providing, through affidavits, evidence of the substance of the expert’s testimony. Absent an affidavit from the expert explaining what he or she would have testified to, or some other verifiable information about what the substance of the expert’s testimony would have been, a[n] applicant fails to raise a genuine issu e of material fact. Self v. State , 145 Idaho 578, 581, 181 P.3d 504, 5 07 (Ct. App. 2007) (internal citations omitted)

. A s to Marsalis’s first ar gument , i.e. , that trial counsel should have retained an expert witness to rebut Dr. LeBeau ’s testimony , t he St ate argued, and the district court found, that trial counsel was not deficient because it chose to address the potential we ak nesses in Dr. LeBeau ’s testimony through cross

- examination. T he State also argues on appeal that, “because the proposed defense exp erts would only have impeached Dr. LeBeau’s methodology, but not his conclusions, and because his conclusions are otherwise supported by the evidence , Marsalis did not show a likelihood that presenting the proposed experts would have affected the outcome o f the trial .” The State’s argument is incorrect for several reasons. First, the cross

- examination of
Dr. LeBeau was in effective be ca use trial counsel did not question the scientific basis underlying
Dr. LeBeau ’s testimony. Rather, trial counsel merely conf irmed with Dr. LeBeau that (1) alcohol affects different people differently, (2) alcohol affe cts the same people differently , and (3) the more accurate the information , the more accurate the results will be when using the Widmark formula

. On the other hand , the affidavits of Drs. Anstine and Fromme question the scientific basis underlying Dr. LeBeau ’s testimony, explaining that the Widmark formula and the Dubowski chart are scientifically unreliable and speculative

. Second, calling into questio n Dr.
LeBeau ’ s methodologies necessarily calls into question the conclusions he reaches based on those methodologies, which is the precise issue Marsalis raises

. Therefore , we hold that there is a genuine issue of material fact as to whether trial counsel was deficient for failing to retain a rebuttal expert witness. As to Marsalis’s second a rgument , i.e. , that trial counsel should have retained an exper t witness to explain the scientific basis behind his blackout defense, neither the State in its motion for summary di smissal nor the d istrict court in its decision addressed t his argument . However, the State on appeal concedes that “[t]he only proposed testimony that does not just attempt to impeach Dr. LeBeau, but arguably is relevant to the facts of the case, is Dr. Fr omme’s testimony about alcohol

- induced blackouts.” Dr. Fromme explained in her affidavit that “[a]lcohol

- induced blackouts are defined as amnesia for all or part of a drinking episode.” Dr. Fromme also explained that, “[w] hile in a blackout, a person is ab le to engage in a range of complex activities,15 such as . . . having sexual intercourse, but they are simply not forming memories for those events.” Dr. Fromme concluded that K.G. was experiencing blac kouts the night she and Marsalis had sexual intercourse

. Dr. Fromme’s report supports Marsalis’s defense that K.G. was conscious during the sexual intercourse, but does not remember consenting to it because she was experiencing a blackout. Th e State argues that the proposed testimony from Dr. Fromme i s entirel y consistent with
Dr. LeBeau ’s testimony at trial , c iting the trial transcript for support

. However, t he State’s reference to the trial transcript refers to Dr. LeBeau ’s testimony discussing amnesia caused by CNS depressants 3 in general . There is no refere nce to any testimony specifically discussing alcohol

- induced blackouts or amnesia

. Accordingly , we hold that there is a genuine issue of material fact as to whether trial counsel w as deficient for failing to retain an expert witness to discuss the scientif ic basis behind Marsalis’s blackout defense. Simila rly, we hold there is a genuine issue of materia l fact as to whether Marsalis was prejudiced by trial counsel’s alleged deficiencies

. Marsa lis maintains that , h ad the jury heard from an expert witness tha t Dr. LeBeau ’s testimony regarding the Widmark formula and the Dubowski chart were unreliable, and had a jury heard from an expert witness regarding blackouts, there is a reasonable probability the outcome of the trial would have been different. Marsalis h as presented sufficient evidence for us to hold that there is a genuine issue of material fact regarding prejudice

. First, i f the jury agreed w ith the defense’s expert that Dr. LeBeau ’s testimony was unreliable and speculative , they would have had no “scie ntific evidence” proving K.G.’s level of intoxication

. Instead, t he jury would have been left with a bar tab, Marsalis’s and K.G.’s statements, and eyewitness testimony. Second, had trial counsel retained an expert witness to discredit Dr. LeBeau ’s testimo ny that K.G. was in a “stupor” and unconscious , the State’s theory of the case would have been severely weakened

. Dr. LeBeau himself testified at trial that “[w]e would not be here if this were a matter of just not remembering.” Thus, having an expert witn ess testify that K.G. was conscious during the sexual intercourse with Marsalis , but merely did not remember it because she was experiencing a blackout , would have undermined
Dr. LeBeau ’s testimony and , ultimately , the State’s theory of the case. Therefore , there is a genuine issue of material fact as to whether Marsalis was prejudiced by trial counsel’s failure to

In sum , becaus e there is a material question of fact as to whether trial counsel was ineffective for failing to challenge Dr. LeBeau ’s testimony and for failing to retain an expert witness to explain Marsalis’s blackout defense, the district court erred in summarily dis missing this claim without reviewing the substance of the expert affidavits submitted by Marsalis. Looking at the evidence in a light most favorable to Marsalis, the nonmoving party, we conclude that Marsalis was entitled to present his evidence at an evid entiary hearing to establish whether trial counsel was deficient and whether he was prejudiced by that deficiency. Therefore , we reverse and remand this claim back to the district court for an evidentiary hearing to determine the same. B. Failure to Present Favorable Eyew itness Testimony

. At trial, the State called two eye witnesses : the driver of the shuttle and a passenger in the shuttle

. The se witnesses testified that K.G. “ was drunk, almost passed out during the cab ride and that she had trouble walking b efore she entered the cab and when she exited the cab in Sun Valley.” Marsalis’s trial counsel did not call any wit nesses to rebut the testimony of the State’s witnesses

. I n his petition, Marsalis alleged that his trial counsel was i neffective for failing to present Jo h n Hampt on, another passenger in the shuttle , at trial

. According to Marsalis, there was no tactic al reason for trial counsel not to call Hampton because he would have testified that K.G. was not forced into the shuttle , that t here was no arg ument between her and Marsalis, and that when she and Marsalis arrived at their destination neither appeared to have any troubl e getting out of the shuttle or walking after exiting the shuttle . Marsalis a rgued that, had trial counsel called Hampton, there i s a reasonable probability there would have been a different result because the testimony of the State’s witnesse s would have been contradicted. The district court summa rily dismissed Marsalis’s claim, finding that [a] witness who wasn’t paying attention and had been drinking that night is not a reliable witness at trial and it is objectively reasonable to avoid calling this person as a witness. This becomes even more true when the only sober person in the car directly contradicts the testimony of the dru nk witness who wasn’t paying attention. Accordingly, the district court held that Hampton’s testimony “ would have had no effect on the outcome of the case. ”17 On appeal, Marsalis contend s that the district court erred in summarily dismissing his claim becau se it improperly found that failing to call the eye witness was objectively reasonable without first addressing the Declaration of [Attorney ] Charles F. Peterson , wherein Peterson declared that a reasonably prudent trial counsel would have called Hampton at trial

. We hold that the district court did not err in summarily dismissing this claim.
“T he decision of what witnesses to call ‘is an area where we will not second guess counsel without evidence of inadequate preparation, ignorance of the relevant law, or other shortcomings capable of objective evaluation.’ ” Payne , 146 Idaho at 563, 199 P.3d at 138 (quoting Larkin , 102 Idaho at 234, 628 P.2d at 1068 ). “In most cases, the court can determine whether defense counsel’s challenged acts or omissions amounted to deficient performance without expert opinion from another lawyer.” Taylor v. State , 145 Idaho 866, 871, 187 P.3d 1241, 1246 (Ct. App. 2008). Here, in the Declaration of [Attorney] Charles F. Peterson, Peterson alleges that trial counsel was ineffectiv e for failing to call “a critical witness’s testimony at trial.” Peterson states that Hampton would have countered the State’s assertion that K.G. was “incapacitated and i ncapable of standing on her own ” and that K.G. “almost passed out during the cab ride and had difficulty walking before she entered the cab and after she exited.” Peterson’s assertions appear to be based on an inaccurate description of Hampton’s anticipated testimony.
In a n interview with a private investigator , Hampton explained that he took the same shuttle back to Sun Valley as Marsalis and K.G

. When asked by the investigator whether he heard any kind of argument between Marsalis and K.G., he explained that he did not. When asked whether Marsalis was physically supporting K.G. as they e xited the shuttle, he explained that he was unsure because he was not paying attention to them

. Finally, when asked whether he had “a visual on them” or whether he saw them “walking somewhere,” he explained that he did

not. Hampton also gave a statement to the Sun Va lley Police Department that he did not remember any deta ils when Marsalis and K.G. were dropped off. The only testimony that may have contradicted the State’s eye witness es ’ testimony i s Hampton’s statement that he did not see
Ma rsalis forcing K. G. into the shuttle . However, that still leaves uncontradicted the testimony that K.G. was drunk, almost passed out during the shuttle ride, and had trouble exiting the shuttle

. Marsalis greatly overstates the impact of such weak evidence on the jury. Ther efore, even with the support of Peterson’s declaration, Marsalis failed to establish a genuine issue of18 material fact as to whether trial counsel’s decision not to call Hampton was due to inadequate
prepar ation, ignorance of the law, or some other shortcom ing. Therefore , we up hold the district

court ’s finding that Marsalis failed to satisfy the first prong of the Strickland test requiring that he show deficiency in trial counsel’s performance and, therefore, we need not address the second
prong of the test , i.e. , prejudice

. See Hollon v. State , 132 Idaho 573, 578, 976 P.2d 927, 932 (1999). C. Failure to Advise Marsalis of his Speedy Trial Rights under the IAD

. While Marsalis was released on bail, he was convicted in Pennsylvania of a separate and unrelated sex offense

. T he Blaine County prosecutor initiated transfer proceedings to get Marsalis back to Idaho to stand trial

. The temporary custody documentation that was sent to the Pennsylvania prison housing Marsalis stated that the Blaine Co unty prosecutor inten ded to bring Marsalis to trial “within the time specified in Article IV(c) of the [Interstate Agreement on Detainers (IAD) ].” 4 Article IV (c) provide s that “trial shall be commenced within one hundred twenty (120) days of the arrival of the prisoner in the receiving state, but for good cause shown in open court, the prisoner or his counsel being present, the court having jurisdiction of the matter may grant any necessary or reaso nable continuance, ” otherwise the indictment shall be dismissed with prejudice. I.C. § 19

- 5001(d)(3) , (5)

. Marsalis was returned to Idaho on August 18, 2008, and appe ared in court the next day . Accordingly, the State was required to bring Marsalis to trial by December 17, 2008. Nevertheless, Marsalis’s t rial was initially set to comm ence on January 5, 2009 , well beyond the 120

- day requirement set out in IAD. It is not clear why the initial trial setting did not conform with the requirements of the IAD. At a scheduling conference on December 1, 2008, held in the judge’s chambers with M arsalis and counsel present, there was some discussion concerning speedy trial , the prosecutor believing he had 180 days to try Marsalis , see I.C. § 19

- 5001(c)(1), 5 rather than 120 days. The parties also discussed continuing the trial so the defense could get a chan ge of venue and DNA results

. On December 5, 2008, the parties stipula ted to a continuance

. On December 8, 2008, the district court issued an order continuing the jury trial. On

4 The Interstate Agreement on Detainers (IAD), an interstate compact authorized by Congress and codified in Idaho at I daho Code sections 19

- 5001 through

- 5008, “is a compact entered into by 48 States, the United States, and the District of Columbia to establish procedures for resolution of one State’s outstanding charges against a prisoner of
ano ther State.” New York v. Hill , 528 U.S. 110, 111 (2000)

. 5 Section 19

- 5001(c)(1) provides that when the prisoner initiates the transfer proceedings, “he shall be brought to trial within one hundred eighty (180) days” after he has delivered written notice of his request for final disposition. The State initiated the transfer proceedings so this provision did not apply.19 December 9, 2008, Marsalis waived his speedy trial rights “guaranteed by the Idaho and United States Constitutions and Idaho Statutory L aw. ” Finally, o n December 12, 2008, the district court entered an order granting a change of venue to Ada County. Ultimately, the trial commence d on April 20, 2009, 124 days past the deadli ne. In his pet ition, Marsalis argued that trial counsel was ineffective for failing to inform him of his speedy trial rights under the IAD. B ecause trial counsel failed to inform him of his rights, Marsalis argued that his waiver of those rights was not in formed and knowing. “As a result of the trial not being h eld within 120 days of [ Marsalis’s ] return to Idaho and there being no valid waiver of that right, it is reasonabl[y] probable that the case against [him ] would have been dismissed for a violation of the Inte rstate Agreement on Detainers.” In its motion for summary dismissal, the State asked the district court to dismiss Marsalis’s claim because Marsalis waived his speedy trial rights under the IAD to receive additional dis covery material and a change of venue. The State also a rgued there was “good cause” for the continuance and that, even if trial counsel incorrectly informed Marsalis that speedy trial was 180 days rather than 120 days, Marsalis “failed to show prejudice. ” The district court summarily dismissed Marsalis’s claim because it foun d Marsalis’s trial counsel permissibly waived Marsalis’s statutory speedy trial right s by agreeing to a con tinuance beyond the 120 days , citing New York v. Hill , 528 U.S. 110 , 115 (2000) (exp laining that counsel

c ould waive his client’s statutory right to a speedy trial because “[s]cheduling matters are plainly among those for which agreement by counsel generally controls.”)

. The district court also found

“ good cause ” on the record : “delay was needed to ensure an u nbiased jury.” 6 Finally, t he district

court found that Marsalis “would have been more severely prejudiced by a failure to continue the trial ” t han he wa s by trial counsel ’s alleged failure to know and advise him of the statutorily imposed deadline for tria l. On appeal, Marsalis contends that the district court erred in dismissing t his claim without first providing him with twenty days’ notice of proposed dismissal as required by Idaho Code section 19

- 4906

. According to Marsalis, the district court was requi red to provide him with notice because it dismissed th e claim on grounds not asserted by the State in its motion for summary dismissal

. Specifically, the district court dismissed the claim, not because Marsalis waived his speedy trial rights, as argued by the State, but because trial counsel wa ived Marsalis’s

6 T he trial court was referencing the time needed to transfer venue to Ada County.20 speedy trial rights for him , as found for the first time by the district court

. Thus, Marsalis asks that we reverse and remand the district court’s dis missal so Marsalis can have twenty days to respond to the court’s grounds for dismissal. The State contends that the district court was not required to provide notice because it relied , in part , on the grounds asserted by the State in its motion for summary dismissal. According to the State, the court’s d ecision is “slightly, but not materially, different.” Thus, the State asks that we affirm the district court’s dismiss al . We hold that the district court should hav e provided Marsalis with twenty days’ notice to respond to its proposed dismissal. Idaho Co de s ection 19

- 4906 permits summary dismissal of a post

- conviction petition, either pursuant to motion of a party or upon the district court’s own initiative : (b) When a court is satisfied, on the basis of the application, the answer or motion, and the reco rd, that the applicant is not entitled to post

- conviction relief and no purpose would be served by any further proceedings, it may indicate to the parties its intention to dismiss the application and its reasons for so doing. The applicant shall be given an opportunity to reply within 20 days to the proposed di smissal

. . . . (c) The court may grant a motion by either party for summary disposition of the application when it appears from the pleadings, depositions, answers to interrogatories, and admissions and agreements of fact, together with any affidavits submitted, that there is no genuine issue of material fact and the moving party is entitled to judgment as a matter of law. I.C. § 19

- 4906(b) , (c) (emphasis added). “Where the state has filed a motion for summary disposition, but the [trial] court dismisses the application on grounds different from those asserted in the state’s motion, it does so on its own initiative and the c ourt must provide twenty days notice.” Saykhamchone v. State , 127 Idaho 319, 322, 900 P.2d 795, 798 (1995). “W hen a trial court summarily dismisses an application for post

- conviction relief based in part on the arguments presented by the State, this is sufficient to meet the notice requirements.” Kelly , 149 Ida ho at 523, 236 P.3d a t 1283

. I n Workman v. State , we clarified that the “ overlap ” between the reasoning in the district court’s decision and the State’s motion for summary dismissal must be “ significant. ” 144 Idaho 518, 524, 164 P.3d 798, 804 (2007)

. The district court’ s reaso ning for dismissal cannot be “ so different in kind as to transform its decision into a sua sponte dismissal .” Id

. Here, the district court’s dismissal of Marsalis’s claim was based primarily on grounds

not raised by the State in its motion for summary dis missal. T he State asserted that Marsalis21 waived his speedy trial rights under the IAD to receive additional di scovery material s and a change of venue. The State also briefly mentioned that there was “good cause” for the waiver and that Marsalis “ failed to show pr ejudice.” The district court , on the other hand, did not address whether Marsalis knowingly waived his statutory speedy trial rights because it found instead that trial counsel waived hi s speedy trial right s for him , citing Hill for the first time

. Moreover, although the district court mentioned “good cause” and prejudice in its deci sion, it did so only in passing. The court briefly c oncluded that there was “ good cause” for the continuance because delay was needed to ensure an unbiased jury and that Marsalis “ would have been more severely prejudiced ” if the continuance had not been granted. Absent from the district court’ s reasoning is the necessary “ overlap ” with the State’s motion that would allow this Court to uphold the district court’s decision w ithout first providing Marsalis with notice

. Therefore, we remand this claim back to the district court so the court can provide Marsalis with twenty days’ notice of its grounds for dismissal of this particular claim pursuant to section 19

- 4906(b). IV. CONCLUS ION For the reasons set forth in this opinion, the Court reverses in part and affirms in par t the district court’s decision summarily dismissing Marsalis’s petition for post

- conviction relief. We affirm the district court’s summary dismissal of Marsalis’s claim that trial counsel was ineffective for failing to call a n allegedly favorable eyewitness at trial. However, w e reverse and remand the case for an evidentiary hearing on Marsalis’s claim that trial counsel was ineffective for failing to challenge the underlying methodolog ies supporting t he State’s expert witness’s testimony and for failing to present an expert witness to discuss the scientific basis behind Marsalis’s blackout defense. We also remand the case back to the district court so it can provide Marsalis with twenty days’ notice to respond to the court’ s grounds for dismissing Marsalis’s claim that trial counsel was ineffective for failing to inform him of his speedy trial rights under the IAD.
