OPINION OF THE COURT
Aрpellant, Roger Re (“Re”), was convicted of the first degree murder of his wife. He was sentenced to life without parole on the murder charge. 1 He sought to defend the charge with the partial defense of extreme emotional distress, 2 and *680 he presented two psychiаtrists who testified in his defense. On rebuttal, the trial court permitted the testimony of a state retained psychiatrist on the issue of Re’s malingering. Re assigned this as error in the course of his appeal and his petition for post conviction relief, each of which was resolved against him. Re filed a Petition for Writ of Habeas Corpus in the United States District Court for the District of Delaware on May 19, 1995. On January 6, 1998, the District Court denied the petition, later issued a certificate of appealability, and this appeal followed. For the reasons which fоllow, we will affirm.
I.
Since this is a habeas corpus petition and the District Court did not hold an evidentiary hearing, our review is plenary.
Robinson v. Arvonio,
II.
Re and his late wife, Jayne, had a tumultuous relationship, and the two had appeared in court on several occasions as a result of domestic disputes. They separated in May, 1976. Re told an acquaintance that he wаs still in love with his wife and that if he ever caught her with another man, he would kill her.
On June 22, 1976, Re saw Jayne return home from a date with Michael Riley, an off-duty New Castle County police officer. Re entered the house through a front window. As Riley was leaving, he heard Jayne screaming that Re wаs in the house with a gun. Riley ran into the house. Re had two guns and was arguing with Jayne about their marriage. When Re moved to shoot Riley, Jayne informed Re that he was a police officer, and Re requested identification, which was produced.
When the front doorbell rang, Re and Jаyne moved towards the door, ordering Riley to stay in the kitchen. Riley went to the car to get his pistol, told a neighbor to call the police, and heard Jayne yell, followed by five shots in rapid succession. As he ran to the door, he heard a shotgun fire. Re climbed out of а window and disposed of the gun. Police determined that a gun found in a nearby garage was the gun used to kill Jayne. It had four live shells and one discharged shell in the revolver’s cylinder. Police determined that, based on the number of shots that Riley heard from the house, Re must have reloаded the gun. A sawed off shotgun was also found in the house. Re surrendered to investigators on June 23, 1976, and had a limited recollection of what occurred.
Re was indicted for first degree murder in July, 1976. Since his mental competency and mental condition were an issue at the time of the shooting, he was ordered transferred to the Delaware State Hospital," and the hospital was ordered to reevaluate his mental condition every six months. In May, 1978, a judge found Re competent to stand trial, but in October, 1979, the Delaware Superior Court declared Re mentally incompetent to stand trial.
In 1984, the Attorney General for the State of Delaware requested that the hospital investigate Re’s privileged confinement conditions because Re had allegedly *681 manipulated certain hospital employees intо granting him special hospital privileges while simultaneously being unresponsive to his doctors and counsel. The State retained Dr. Dietz, an outside expert, to conduct this inquiry. He examined Re once in November, 1984 and again in May, 1985. He then wrote a report in which he exprеssed the opinion that Re was malingering, and had been since 1982. Based in part on this finding, Re was declared competent to stand trial.
After Re was declared competent to stand trial, he asserted a partial defense of extreme emotional distress. He cоnceded that he had intentionally killed his wife, but claimed that he had acted under extreme emotional distress. Two clinical psychologists, Dr. Irwin G. Weintraub and Dr. Cono Galliani, testified for the defense at trial. Dr. Weintraub, who had examined Re twice (in 1975 and 1985), testified that Re was limited in his ability to сope with stress, noted the increasing intensity of the confrontations, and concluded that Re had overreacted when faced with an increasingly stressful and intolerable situation. He concluded that Re was under extreme emotional distress when he killed Jayne, though he had no mental illness or personality disorder.
Dr. Galliani, the chief psychologist at Delaware State Hospital, saw Re on several occasions, and interviewed Re before and during trial at defense counsel’s request. Dr. Galliani also concluded that, at the time of the homicide, Re was under extreme emotional distress. In prior interviews, Re had claimed no memory of the homicide and insisted that he did not kill Jayne, but in an interview three days into the trial, Re, under hypnosis, recalled the events surrounding the homicide.
In rebuttal, the prosecution called Dr. Dietz, who had not testified in the state’s case-in-chief and was a surprise witness. The defense objected to Dr. Dietz’s testimony on the ground that it violated the Sixth Amendment because Dr. Dietz had not notified counsel of his 1984 interview with Re. The objection was overruled. Dr. Dietz testified that Re was a “malingerer” with an “anti-social personality disorder.” Dr. Dietz admitted that his malingering and anti-social tendencies were not relevant to the issue of extreme emotional distress, and indeed declined to express an opinion about the existence of еxtreme emotional distress, since the concept was a legal one and not a psychological or psychiatric one. Dr. Dietz conceded that he had marginal factual evidence to support his contention that Re was anti-social, and admitted that Re’s malingering was unrelated to his mental condition at the time of the shooting.
Malingering is “the voluntary production of symptoms ... The essential feature of malingering is the voluntary production and presentation of false or grossly exaggerated physical or psychological symptoms which are produced in pursuit of a goal that is obviously recognizable to evade criminal prosecution.” (Dr. Dietz’s testimony, Joint App. at 67-68.) Dr. Dietz gave examples in support of his contention that Re was feigning incompetence. 3 The defense’s objection to this line of examination was overruled. The trial judge ruled that the defense had opened that issue by, calling Dr. Galliani as a witness. Since Dr. Galliani based his opinion upon his contact with Re in his role as the chief psychologist at Delaware State Hosрital, Dr. Dietz was permitted to testify about information he obtained through his investigation of *682 Re’s conduct at the hospital, and his conclusions based on that information.
III.
This appeal -involves whether or not Re’s counsel had -notice of Dr. Dietz’s examination in conformity with the Sixth Amеndment to the United States Constitution; whether or not any notice he did receive was defective because it did not notify counsel of the “expanded scope” of the examination; and whether the lack of notice led to prejudicial rebuttal testimony by Dr. Dietz and created a structural defect in Re’s trial. Re contends that counsel was not notified of the 1984 Dietz examination, and since the examination concerned a subject beyond his mental competency, viz malingering, his counsel should have been notified.
Estelle v. Smith,
Re’s counsel did not have a right, under the Sixth Amendment, to be present and observe the 1984 Dietz examination.
Estelle,
Counsel likewise had notice of the Attorney General’s investigation concerning Re’s potential manipulation of hospital personnel. It is difficult to conclude that the subject of malingering was not within the overriding subject of the periodic examinations, - viz mental competence to stand trial. Whether Re was malingering was certainly related and within the scope of that subject. This is not the same situation presented by
Estelle
and
Satter-white.
In
Estelle,
the examination was expanded to consider the defendant’s future dangerousness to society, and it was to be used for the specific purpose of satisfying that element in the death penalty phase of sentencing. The Supreme Court held the failure to notify counsel of that subject violated the defendant’s Sixth Amendment rights.
Estelle,
Dr. Dietz’s rebuttal testimony did not constitute a Sixth Amendment structural defect in the Re’s trial. It did not contaminate the fairness of his trial.
At trial, Re put his mental state in issue with his own evaluations and expert psychiatric testimony. He therefore cannot challenge Dr. Dietz’s rebuttal testimony on Sixth Amendment grounds.
Buchanan,
Re claims that the lack of notice of the Dietz examination and its scope effectively deprived him of his right to counsel under the Sixth Amendment, because counsel did not have the opportunity to change his strategy to eliminate the use of Dr. Galliani’s testimony and simply rely on the testimony of Dr. Weintraub. This, of course, begs the question of the notice of the scope of the Dietz examination. Malingering was a fair subject to anticipate in the Dietz exam given the subject of competency to stand trial. Moreover, the 1985 еxamination, to which Re’s counsel consented, made him aware, in advance of trial, of the results of the 1984 examination. Finally, we also hold that even if there was an error in this case, it was a harmless error and not a structural defect.
See Satterwhite,
The judgment of the District Court will be affirmed.
Notes
. ' He was also convicted of possession of a deadly weapon during the commission of a fеlony and possession of a destructive weapon.
. Under Delaware law, the fact that the accused intentionally caused the death of another person under the influence of extreme emotional distress is a mitigating circumstance, reducing Murder in the First Degree to Manslaughter. The defendant must prove that he acted under the influence of extreme emotional distress by a preponderance of the evidence and that there is a "reasonable explanation or excuse” for his extreme emotional distress. The reasonableness of the explanation or excuse shall be determined from the viewpoint of a reasonable person in the defendant's situation under the circumstances as he believed them to be.
See State v. Moyer,
. The examples centered around the fact that Re did not appropriately respond to Dr. Dietz's questions, and uttered incoherent and nonsensical remarks.
