OPINION
§1 Defendant Terry James Marble appeals from convictions of four counts of aggravated sexual abuse of a child. See Utah Code Ann. § 76-5-404.1 (Supp.1997) (amended 1998); id. § 76-5-404.1 (1999) (amended 2003). 1 We affirm.
BACKGROUND 2
T2 Marble's daughter, A.S. (Daughter), was born in 1988 after Marble and Daughter's Mother (Mother) had been living together for two years. Eventually, Marble and Mother married in 1990, and had two additional children. From the beginning, Marble and Mother's relationship was both physically and emotionally abusive. Marble, an alcoholic, not only abused Mother but at times also physically abused his children. Because of Marble's alcoholism and abuse, Mother left Marble several times during their marriage only to later return.
1 3 On September 11, 1997, Mother permanently separated from Marble taking the three children, including Daughter, with her. Mother also filed for divorce and obtained a protective order against Marble. In December 1997, Marble received and began exercising non-custodial visitation rights with his children. Marble and Mother's divorce became final in January 1998. The divorce decree awarded sole custody of the children to Mother, and Marble was granted visitation rights provided he did not use alcohol while with the children. In October 1998, Marble's visitation rights were terminated. During this period-from the time Mother permanently separated from Marble in September 1997 until Marble's visitation rights were terminated in October 1998-Daughter alleges that, on multiple occasions, Marble sexually abused her by rubbing her chest, digitally penetrating her vagina, and placing her hands on his penis.
1 4 Although the alleged incidents of abuse occurred in 1997 and 1998, Daughter did not report the abuse until 2002 when she entered the ninth grade. At that time, Daughter discovered that her friend had been sexually abused by a relative. Upon hearing her friend's story, Daughter became more comfortable with sharing her own experiences of abuse allegedly perpetrated by Marble. Daughter first confided in her friends and later confided in Mother, a therapist, and the police. Corporal Jeff Johnson, an officer with the Brigham City Police Department, was assigned to investigate Daughter's allegations against Marble. Johnson was already acquainted with Marble. On prior occasions, Johnson had responded to police *373 calls and participated in an arrest involving Marble.
T5 In February 2003 Johnson arrested Marble, who was charged with ten counts of aggravated sexual abuse of a minor, five occurring between October 1997 and March 1998, and another five occurring on or after March 1998. Before trial, however, the State filed an amended information dropping the five charges related to the earlier time period. 3 The information alleged two aggravating factors: (1) that Marble, as the victim's father, occupied a position of special trust; and (2) that Marble had committed five or more acts of sexual abuse before, after, or as part of the same course of conduct. Before trial, defense counsel stipulated that Marble held a position of special trust over Daughter by reason of being her father. Following the stipulation, the State abandoned the second aggravating factor.
T6 Marble waived his right to a preliminary hearing and proceeded to a jury trial. At trial, both Daughter and Johnson testified as prosecution witnesses. Daughter was the first witness called by the prosecution. Later, the prosecution called Johnson. During defense counsel's cross-examination of Johnson, the following dialogue ensued:
Q. [Defense Counsel:] ... [Wle've heard the testimony that, [Daughter] hated her father, was mad at him, lived in a terrible situation. Admittedly a situation I wouldn't want to live in. I don't have kids, but I wouldn't want my kids to live in that. Is it possible that she was coached in such a way as to make allegations that could be false?
A. [Johnson:] I guess your question here is ["Ils it possible?["] Yeah, that's possible. Do I believe that occurred? No.
Q. [Defense Counsel:] How did you come to that conclusion in this case?
A. [Johnson:l You know, one of the things I feel like I have become fairly adept at through my training and experience is discerning truthful behavior, especially truthful behavior in an interview. Every time I have interviewed [Daughter], based upon her emotional response, her body positioning, her eye contact, everything that I have been trained to watch for, she has been in my mind been truthful.
Not only that, but I would say there has been so much corroborating evidence on her part that is not verbal as to what occurred that it lent an extreme credence to me that this was a truthful allegation.
At the time defense counsel elicited this testimony, counsel did not object to Johnson's characterization of Daughter as truthful. Instead, counsel pressed J ohnson to recount the additional corroborating evidence that he relied on in his investigation. Counsel elicited testimony that tended to show that there was no physical evidence collected and that the only other corroborating evidence was an interview with Mother. Counsel also elicited testimony from Johnson that indicated Johnson knew Marble and Mother had a history of making allegations against one another. Finally, counsel explored Johnson's aequain-tance with Marble through his involvement in previous investigations and a previous arrest. At the close of evidence, the jury returned a verdict of guilty on four counts of aggravated sexual abuse of a child. Marble appeals.
ISSUE AND STANDARD OF REVIEW
T7 Marble asserts that he received ineffective assistance of counsel in violation of his Sixth Amendment rights under the United States Constitution. "An ineffective assistance of counsel claim raised for the first time on appeal presents a question of law," which we review for correctness. State v. Clark,
ANALYSIS
T8 Marble asserts that he is entitled to a new trial because his defense counsel rendered ineffective assistance in violation of the Sixth Amendment. To prevail on his ineffective assistance of counsel claim Marble must show: "(1) that counsel's performance was objectively deficient, and (2) a reasonable probability exists that but for the deficient
*374
conduct defendant would have obtained a more favorable outcome at trial." Id. (citing Strickland v. Washington,
I. Daughter's Truthfulness
T9 Under rule 608 of the Utah Rules of Evidence, "(tlhe credibility of a witness may be attacked or supported by evidence in the form of opinion or reputation." Id. "This rule permits testimony concerning a witness's general character or reputation for truthfulness or untruthfulness but prokibits any testimony as to a witness's truthfulness on a particular occasion." State v. Rimmasch,
110 Thus, Marble argues that because it is clearly impermissible under rule 608 and the Rimmasch line of cases for an expert "to express an opinion as to whether a child was truthful when making statements to the expert about sex abuse," Ramsey,
¶ 11 Under Strickland, the defendant must first demonstrate that counsel's performance was objectively deficient. To do this, the defendant "must overcome the strong presumption that his trial counsel rendered adequate assistance, by persuading the court that there was no conceivable tactical basis for counsel's actions." Clark,
{12 Utah courts have recognized that when viewing "the variety of cireumstances faced by defense counsel," a conscious choice not to object to arguably inadmissible testimony may, at times, fall within "the range of legitimate decisions regarding how best to represent a criminal defendant," Strickland,
€ 13 When reviewing the trangeript of defense counsel's cross-examination of Johnson in its entirety along with closing arguments, counsel's trial strategy is apparent. Counsel's cross-examination was engineered to highlight Johnson's motives and bias in conducting the investigation thereby undermining the overall quality of the State's case. See Bullock,
€ 14 Defense counsel's trial strategy is illustrated by counsel's closing arguments when he stated:
I'm troubled by this case. I'm troubled by a Brigham City police officer who knows Terry Marble.... You know what, he knows him and he knows he's a bad person. And now these charges are brought and what does [Johnson] do to investigate? What does he do to investigate the case?
[Johnson] was instructed by the prior county attorney ... to be careful. These people have accused each other of things in the past. Investigate this carefully....
*376 What does he do? He ignores that. You know why? Because he leapt to the conclusion at the very beginning that Terry Marble, the town drunk, ... is guilty of this crime, sexual abuse of a child.
No physical exam was done, no talking to any other witnesses. Why? ... [Johnson] made a decision early on that by looking at [Daughter, "II could tell by looking at her she's telling me the truth.["}
115 Because it is clear from the record that counsel had a conceivable trial strategy in eliciting the challenged testimony from Johnson, Marble has failed to demonstrate that defense counsel's performance was objectively deficient under the first prong of the Strickland test. See Strickland v. Washington,
II. Stipulation to Position of Special Trust
116 Marble also argues that counsel's performance was deficient because, based on an oversight or misreading of the statutes in effect at the time of the alleged sexual abuse, counsel stipulated that Marble held a position of special trust with respect to Daughter thereby satisfying an aggravating factor of the crime.
¶ 17 Marble was ultimately charged under Utah Code section 76-5-404.1 with five counts of aggravated sexual abuse of a child occurring on or after March 1998. Because an amendment to section 76-5-404.1 took effect on May 4, 1998, two different versions of section 76-5-404.1 were applicable to Marble's conduct during the time frame of the charges. See Act of 1998, ch. 181, § 1, 1998 Utah Laws 418, 418. The 1997 version of the statute, see Utah Code Ann. § 76-5-404.1 (Supp.1997) (amended 1998), was applicable from March 1, 1998, through May 3, 1998, of the charged period. Alternatively, the 1998 version, see Utah Code Ann. § 76-5-404.1 (1999) (amended 2003), was in effect on and after May 4, 1998. In his brief, Marble argued that, without exception, the 1997 version of the statute excluded natural parents from holding a position of special trust; and therefore, defense counsel's performance was objectively deficient when counsel stipulated to the aggravating factor for the March 1 to May 3, 1998, time period. 5 We disagree.
¶18 Prior to the 1998 amendment, Utah Code section T6-5-404.1 read in pertinent part:
(8) A person commits aggravated sexual abuse of a child when in conjunction with the offense described in [slubsection (1) any of the following cireumstances have been charged and admitted or found true in the action for the offense:
(Lh) The offense was committed by a person who occupied a position of special trust in relation to the victim; "position of special trust" means that position occupied by a person in a position of authority, ... and includes, but is not limited to, the position occupied by a youth leader or recreational leader who is an adult, adult athletic manager, adult coach, ... though a natwral parent, stepparent, adoptive parent, or other legal guardian, not including a foster parent, who has been living in the household, is not a person occupying a position of special trust under this subsection.
Id. § 76-5-404.1(8)(h) (emphasis added). Thus, contrary to Marble's contention, the plain language of the 1997 version of Utah Code section 76-5-404.1 does not categorical ly exclude all natural parents from holding a position of special trust. See id. § 76-5-404.1 (Supp.1997) (amended 1998). Rather, the statutory language exempted natural parents only when the "natural parent ... *377 hald] been living in the household" with the victim. Id.
{19 At oral argument, Marble's counsel argued, for the first time, that the 1997 version of Utah Code section 76-5-404.1 was ambiguous. First, Marble argued that the statute's language did not make it clear whether the natural parent was required to live in the household with the victim before, during, or after the sexual abuse to fall within the meaning of the exemption. Thus, Marble argues, that because he lived in the same household with the victim six months prior to the period of the alleged abuse, he was exempted from occupying a position of special trust. Marble also contends that the statute did not define the phrase "living in the household" and that, therefore, it could have conceivably applied to a parent exercising non-custodial visitation rights. However, because Marble did not raise these statutory construction arguments in his brief, we decline to address the merits of the arguments here. See Valcarce v. Fitzgerald,
120 However, even assuming that Marble's argument-that natural parents are categorically excluded from holding a position of special trust under the 1997 statute-has merit, Marble has failed to demonstrate that his counsel's performance was deficient, based upon the state of the law at the time of trial. See State v. Dunn,
21 Here, we are not persuaded that there was "no conceivable tactical basis for counsel's actions." State v. Clark,
CONCLUSION
122 Marble has failed to show that counsel rendered ineffective assistance when counsel (1) elicited arguably inadmissible testimony bearing on Daughter's truthfulness in making allegations of sexual abuse against Marble or (2) stipulated that Marble held a position of special trust with respect to Daughter. In both instances, Marble has failed to meet his burden of showing that counsel's acts or omissions were objectively deficient under the first prong of the Strickland test. Therefore, we hold counsel's performance was constitutionally sufficient.
1 23 Affirmed.
T 24 WE CONCUR: PAMELA T. GREENWOOD and WILLIAM A. THORNE JR., Judges.
Notes
. Because Marble's criminal acts occurred while previous versions of the criminal statutes were in force, we refer to the earlier sections of the Utah Code. See Cook v. City of Moroni,
. Facts are recounted "in a light most favorable to the [jury] verdict." State v. Hamilton,
. After the close of the State's case, one of the remaining five charges was also dismissed on the ground that the State had presented evidence of only four-not five-incidents of abuse occurring on or after March 1998.
. Marble concedes that direct plain error analysis is inappropriate here because defense counsel invited the alleged errors by eliciting the challenged testimony and by stipulating to the challenged aggravating factor. See State v. Dunn,
. Marble does not argue that counsel's stipulation was objectively deficient when viewed in light of the 1998 version of the statute. The 1998 amendment expressly included natural parents within the enumerated classes of persons who held a position of special trust. See Act of 1998, ch. 131, § 1, 1998 Utah Laws 418, 418 (codified as amended at Utah Code Ann. § 76-5-404.1(3)(h) (1999) (amended 2003)) (" '[Plosition of special trust' means that position occupied by a person in a position of authority ... and includes, but is not limited to, a ... natural parent, stepparent, adoptive parent. ..."}.
