Ronald Lee Stewart appeals from the district court’s 1 order denying his petition for a writ of habeas corpus under 28 TJ.S.C. § 2254. Stewart argues that the district court erred in denying his request for an evidentiary hearing and his claim of ineffective assistance of trial counsel. We affirm.
I.
Armed with a firearm, Stewart robbed the cashier’s office at Drake University in Des Moines, Iowa, on June 25, 1987. The state charged Stewart with first-degree robbery and going armed with intent. Stewart filed a pro se pretrial motion raising the defense of diminished responsibility. He also requested subpoenas for fifteen out-of-state witnesses, claiming that each had knowledge of his drug addiction and his mental capacity at the time of the robbery. The trial court informed Stewart that he needed to reduce the number of his requested witnesses. The court arranged for Stewart to use the state’s facilities to telephone his prospective witnesses so that he could determine which ones would be the most helpful in developing his defense. Nevertheless, when Stewart and his attorney went to telephone the witnesses, Stewart refused to call them.
*743 At Ms jury trial, Stewart’s only witness was Dr. Karl Northwall, a board-certified psycMatrist. Dr. Northwall testified that Stewart had a history of cocaine, marijuana, and alcohol dependence. He further testified that if Stewart had used substances as he claimed he did, his judgment would have been impaired at the time of the offenses. On cross-examination, Dr. Northwall acknowledged that his evaluation of Stewart was based primarily on information provided by Stewart without any independent corroboration. The court instructed the jury on the diminished-responsibility defense. The jury rejected the defense, however, and convicted Stewart on both counts.
Stewart’s counsel filed a motion for a new trial, and Stewart filed his own supplemental new-trial motion, claiming,
inter alia,
ineffective assistance of counsel. The trial court denied both motions. On direct appeal, Stewart argued that his trial counsel had been ineffective in not contacting his out-of-state witnesses. The Iowa Court of Appeals rejected the claim, noting that Stewart had played an active role in his defense and that he had refused, against his attorney’s advice, to utilize the opportunity to telephone his prospective witnesses.
State v. Stewart,
Stewart filed this habeas action, again claiming, inter alia, that trial counsel had been ineffective in not contacting his prospective witnesses. As evidence for the ineffective-assistance claim, Stewart’s habeas counsel obtained six affidavits from five individuals who were on Stewart’s witness list. Stewart asked the district court for an evi-dentiary hearing to introduce the affidavits into the record. The district court denied Stewart’s request, as well as Ms ineffective-assistance claim.
II.
Stewart argues that the district court erred in denying him an evidentiary hearing. Stewart contends that the affidavits demonstrate that if the affiants had been called to testify they would have corroborated Dr. Northwall’s testimony eoncermng Stewart’s drug addiction and mental capacity.
Stewart is entitled to an evidentia-ry hearing to introduce additional evidence “if he can show cause for Ms failure to develop the facts in state-court proceedings and actual prejudice resulting from that failure.”
Keeney v. Tamayo-Reyes,
— U.S. -, -,
We also find that Stewart could have presented this evidence in a state post-conviction action. We recognize that Iowa law generally prohibits a postconviction petitioner from relitigating issues that have already been adjudicated on direct appeal. Iowa Code Ann. § 822.8; Jones
v. Scurr,
To establish an ineffective-assistance claim, Stewart must show that his counsel’s performance was deficient and that the deficient performance prejudiced his defense.
Strickland v. Washington,
The order denying the petition for writ of habeas corpus is affirmed.
