Background
Richard Thomas Hamilton was convicted in 2018 of two counts of sexual conduct with a minor and four counts of molestation of a child—all class 2 felonies and dangerous crimes against children. The charges arose from the sexual abuse of his step-granddaughters (ages 7 and 11) and three teenagers he had met through his work as a youth martial arts instructor. Hamilton was sentenced to consecutive life terms on the sexual conduct counts and consecutive 28-year terms on each molestation count.
At trial, the prosecution introduced evidence of Hamilton’s sexual conduct with the three teenagers through a Rule 404(c) motion to show propensity. A prosecution expert psychologist, Dr. Tina Garby, testified that Hamilton had a propensity for sexual behavior toward minors. Hamilton’s trial counsel, having retained a defense expert Dr. Phillip Esplin, made the strategic decision not to call him to rebut Dr. Garby’s testimony after determining that favorable concessions had already been extracted from Dr. Garby on cross-examination.
Hamilton appealed his convictions, which were affirmed. Years later, in 2024-2025, he filed a post-conviction relief (PCR) petition claiming his trial counsel was ineffective for failing to call Dr. Esplin at the Rule 404(c) hearing and for failing to present certain evidence at trial. He also requested appointment of an expert witness to support his ineffective assistance claim. The trial court dismissed his petition.
The Court’s Holding
The Arizona Court of Appeals granted review but denied relief. The court held that Hamilton failed to establish a colorable claim of ineffective assistance of counsel. Under the governing legal standard, a defendant must demonstrate both that counsel’s performance fell below objectively reasonable standards and that the deficient performance prejudiced the defendant. However, matters of trial strategy and tactics are committed to defense counsel’s judgment and generally cannot support an ineffective assistance claim if the challenged conduct has a reasoned basis.
The court found that trial counsel’s decision not to call Dr. Esplin had ample reasoned basis: counsel had consulted with a qualified expert, determined through cross-examination of Dr. Garby that key favorable testimony had already been elicited (particularly the concession that there is a vast difference between abuse of postpubescent and prepubescent children), and concluded that presenting Dr. Esplin’s testimony risked undermining the defense’s argument for excluding the prior-act evidence. Counsel also noted that Dr. Esplin agreed with at least some aspects of Dr. Garby’s testimony, which the prosecution could use to enhance Dr. Garby’s credibility.
The court rejected Hamilton’s argument that counsel should have obtained a written report from Dr. Esplin instead, finding this amounted to speculation about what an expert could have said. The court also rejected Hamilton’s request for appointment of an additional expert, holding that once counsel has retained a qualified expert, the failure to consult with additional experts does not constitute ineffective assistance. Finally, the court found that Hamilton waived his claim of trial ineffectiveness by failing to identify specific examples or articulate concrete arguments, instead asking the court to review over 2,200 pages of documents.
Key Takeaways
- Trial counsel’s strategic decisions regarding expert witness testimony are protected from ineffective assistance review absent a showing that the decision lacked any reasoned basis.
- A defense attorney’s decision not to call an expert witness will not support an ineffective assistance claim if the attorney consulted with a qualified expert and had reasoned strategic reasons for the decision.
- Appellate courts will not second-guess trial strategy by engaging in speculation about what different or additional expert testimony might have shown.
- Ineffective assistance claims must be supported by specific factual allegations; broad requests that courts review voluminous documents in search of support for a claim constitute waiver.
Why It Matters
This decision provides important guidance on the boundaries of ineffective assistance of counsel claims involving expert witness strategy. By affirming that counsel’s decision not to call an expert is protected when based on sound strategic reasoning—including the judgment that eliciting favorable testimony on cross-examination from the prosecution’s own expert may be preferable to presenting a defense expert who agrees with some of the prosecution’s points—the court reinforces the deference appellate courts give to trial counsel’s tactical judgments. This protects defense attorneys’ ability to exercise professional judgment without constant second-guessing in post-conviction proceedings.
The decision also underscores that petitioners seeking post-conviction relief bear the burden of clearly articulating their claims with specific factual support rather than asking courts to sift through extensive documents. For defendants, this means that effective PCR practice requires precision in identifying and developing particular ineffective assistance claims with concrete examples and legal arguments.
