    APPEAL FROM THE UNITED STATES DISTRICT COURT
    FOR THE DISTRICT OF COLORADO
    (D.C. No. 91-N-827)

    Section, Gale A. Norton, Colorado Attorney General, with him on the brief, Denver,

    Before HENRY, MURPHY, and RONEY*, Circuit Judges.
    HENRY, Circuit Judge.
    *
    The Honorable Paul H. Roney, Senior Circuit Judge for the Eleventh Circuit
    sitting by designation.
    Respondents William Price and Gale Norton1 appeal the district court’s order
    granting Richard Demarest’s petition for a writ of habeas corpus pursuant to 28 U.S.C. §
    2254 and vacating his conviction for first degree murder in Jefferson County, Colorado.
    See Demarest v. Price, 
    905 F. Supp. 1432
    (D. Colo. 1995). The district court concluded
    that by failing to adequately investigate the case, interview witnesses, and present medical
    evidence, Mr. Demarest’s attorney in the Jefferson County murder trial deprived him of
    his Sixth Amendment right to effective assistance of counsel. See 
    id. at 1446-54.
    Respondents argue on appeal that Mr. Demarest may not seek redress in federal court
    because he did not exhaust his state court remedies in that he did not fairly present
    important evidence regarding his trial counsel’s performance to the Colorado state courts.
    Initially, we conclude that the provisions of the Antiterrorism and Effective Death
    Penalty Act of 1996 (AEDPA), Pub. L. No. 104-132, 110 Stat. 1214 (1996), that amend
    the habeas corpus statutes should not be applied to this case because Mr. Demarest’s
    petition was filed before the AEDPA’s effective date. See Lindh v. Murphy, 
    117 S. Ct. 2059
    , 2068 (1997). Then, applying the pre-AEDPA habeas corpus provisions, we hold
    that Mr. Demarest did not exhaust his state remedies. We therefore vacate the district
    court’s order granting Mr. Demarest’s petition and remand the case to the district court
    for several determinations.
    1
    We refer to respondents collectively as “the state.”
    2
    On remand, we direct the district court to first determine whether Mr. Demarest’s
    ineffective assistance of counsel claim, based on the new evidence presented at the
    federal evidentiary hearing, would now be procedurally barred under Colorado law. In
    the event that the district court concludes that Mr. Demarest’s claim would not now be
    procedurally barred, we hold, it should dismiss the claim without prejudice so that it may
    now be adjudicated in the Colorado courts. Alternatively, if the district court concludes
    that Mr. Demarest’s claim would now be procedurally barred in the Colorado courts, it
    should then determine whether Mr. Demarest can establish either that there was cause for
    the default and prejudice resulting from the violation of federal law, or that failure to
    consider his claim on the merits would result in a fundamental miscarriage of justice. In
    the event that Mr. Demarest establishes either cause and prejudice or a fundamental
    miscarriage of justice, the court should proceed to the merits.
    I. BACKGROUND
    Early in the afternoon of February 9, 1981, petitioner Demarest called the
    Jefferson County Sheriff’s Department from a neighbor’s home and reported that he had
    just discovered the body of his friend Ronald Hyams in the house that the two shared in
    Evergreen, Colorado. “In a panicked, sobbing voice,” Demarest, 905 F. Supp at 1436,
    Mr. Demarest told the emergency operator that it appeared that Mr. Hyams had been
    murdered. After placing the call, Mr. Demarest ran back to his house and sat down under
    3
    a tree in the front yard next to a gravel driveway, where a neighbor waited with him for
    law enforcement officials to arrive.
    Approximately ten minutes after Mr. Demarest’s call, Jefferson County deputy
    sheriffs discovered Mr. Hyams’s body in a downstairs bedroom. Mr. Hyams’s head was
    wrapped in a bathrobe and there were puncture wounds around his neck and collarbone.
    The pathologist who conducted the autopsy testified that Mr. Hyams died from “the
    combined effects of trauma to the head[,] . . . blood loss from the stab wound in the left
    neck[,] and from the complication of strangulation of the neck.” 
    Id. (quoting Rec.
    vol.
    V, Trial Tr. of State v. Demarest, No. 81 CR 259, Jefferson County District Court, at
    638).
    During the period immediately after Mr. Hyams’s murder, Mr. Demarest
    experienced substantial emotional trauma and required psychiatric treatment. On the day
    of the murder, a neighbor testified, Mr. Demarest was distraught and in shock. As a
    result, medical personnel took him to a local emergency room. Carol Lee Held, Mr.
    Demarest’s other housemate, took him home later that day, but she observed that Mr.
    Demarest soon grew unresponsive and appeared to fall into a trance. Ms. Held called the
    sheriff’s office for assistance, and when the deputies arrived, they found Mr. Demarest
    “lying on the floor in a fetal position, tightening his muscles, and clenching his fists.” 
    Id. at 1436
    (citing Trial Tr. of State v. Demarest, No. 81 CR 259, Jefferson County District
    Court, at 289-90). The deputies took Mr. Demarest back to the local medical center, and
    4
    he was then transferred to the psychiatric ward of another hospital. A psychiatrist
    diagnosed him as suffering from adult situational reaction caused by acute stress and
    treated him with a variety of drugs. Mr. Demarest was released from the psychiatric ward
    on February 11, 1981.
    During an interrogation at the sheriff’s office on February 12, 1981, Mr. Demarest
    suffered another breakdown. When shown a picture of Mr. Hyams, he began shaking, fell
    on the floor, and curled into a fetal position. Mr. Demarest was taken back to the
    hospital’s psychiatric ward, where he remained until February 23, 1981. Another
    psychiatrist concluded that he suffered from an “adult situational disorder with
    withdrawal[,]”see 
    id. at 1437,
    and treated him with prescription drugs.
    On the three separate occasions shortly after the murder when deputies questioned
    him, Mr. Demarest denied any involvement in Mr. Hyams’s murder. He reported that on
    the morning of the murder, he had borrowed Mr. Hyams’s car, stopped at a McDonald’s
    restaurant to drink coffee, and had then driven to Mr. Hyams’s dentist’s office to pick him
    up after an appointment. When he arrived at the dentist’s office, he learned that Mr.
    Hyams had missed the appointment. According to Mr. Demarest, he then returned home
    and discovered the body.
    During the questioning, deputies observed that Mr. Demarest had scratches on the
    back of his hands and face. When asked about the scratches, Mr. Demarest said that he
    had pounded his fists into the gravel driveway while waiting for emergency personnel
    5
    after discovering Mr. Hyams’s body. As to his face, Mr. Demarest said that he had
    scratched it at the medical center on the afternoon of the murder.
    In March 1981, the Jefferson County District Attorney charged Mr. Demarest with
    the murder of Ronald Hyams. The Jefferson County District Court appointed a state
    public defender as Mr. Demarest’s counsel. The public defender represented Mr.
    Demarest until June 29, 1981, when Mr. Demarest retained William A. Cohan, who
    served as his defense attorney throughout the trial.
    The Jefferson County District Court conducted Mr. Demarest’s trial in October
    1981. The prosecution contended that the following events occurred on the morning of
    February 9, 1981: Mr. Demarest struck Mr. Hyams’s head from behind and bludgeoned
    his face; Mr. Hyams struggled and scratched Mr. Demarest’s hands and face; Mr.
    Demarest eventually managed to subdue Mr. Hyams; and, after Mr. Hyams had passed
    out, Mr. Demarest deliberated for ten to fifteen minutes and then killed Mr. Hyams by
    stabbing and strangling him. Next, according to the prosecution’s theory, Mr. Demarest
    drove to the dentist’s office to establish an alibi. Mr. Demarest’s apparent shock upon
    discovering Mr. Hyams’s body, the prosecution suggested, was a contrived reaction
    intended to divert suspicion.
    At trial, the district attorney offered scientific and forensic evidence to support this
    theory. Dick Hopkins, a detective with the Arapaho County Sheriff’s Department whom
    the court allowed to testify as an expert in blood-spatter analysis, testified that the pattern
    6
    of blood stains at the murder scene indicated that Mr. Hyams was murdered by a tall,
    strong right-handed man. Detective Hopkins also testified that the scratches on Mr.
    Demarest’s hands appeared to come from fingernails and that the blood stains at the
    murder scene indicated that about ten to fifteen minutes had elapsed between the initial
    blows to Mr. Hyams’s head and the strangulation and stabbing.
    Nevertheless some of the prosecution’s own witnesses revealed flaws in the state’s
    theory. A hair and fiber expert testified that facial hair discovered underneath Mr.
    Hyams’s fingernails could not have come from Mr. Demarest. A blood expert testified
    that there was no evidence that blood had been transferred between Mr. Hyams and Mr.
    Demarest.
    The district attorney also introduced testimony about the scratches on Mr.
    Demarest’s hands and face. A workman and a neighbor who observed Mr. Demarest as
    he waited by the gravel driveway for emergency personnel to arrive after calling the
    sheriff’s department both testified that they did not observe Mr. Demarest hitting his
    hands on the gravel. Mark Davidson, a volunteer fireman who spoke to Mr. Demarest
    while he waited outside the house, similarly stated that he did not notice Mr. Demarest
    hitting his hands on the gravel and would have remembered seeing it. Carol Held, the
    housemate of Mr. Demarest and Mr. Hyams, testified that when she met Mr. Demarest at
    the local medical center on the afternoon of February 9, she noticed that his right hand
    was swollen and there was a small amount of blood on his cuticles. She added that Mr.
    7
    Demarest told her that he had scratched his hands by hitting rocks. Finally, Eileen
    Bausch, a receptionist at Mr. Hyams’s dentist’s office, testified that she did not see Mr.
    Demarest’s hands when he entered the office. The district attorney invoked Ms. Bausch’s
    testimony in arguing that Mr. Demarest’s hands were already scratched--from the struggle
    with Mr. Hyams--when he entered the dentist’s office and that he concealed his hands
    from Ms. Bausch so that he could concoct the story about pounding his fists on the gravel
    when he later returned home.
    The prosecution also offered testimony regarding a damp washcloth found in a
    shower near Mr. Hyams’s bedroom and testimony indicating that Mr. Demarest had
    changed shirts on the morning of the murder. According to Detective Hopkins, the
    washcloth appeared to contain traces of blood. The prosecution argued that an intruder
    would not have showered after killing Mr. Hyams and that, as a result, the damp
    washcloth constituted additional evidence that Mr. Demarest was the murderer. As to Mr.
    Demarest changing shirts on the morning of the murder, the prosecution argued that the
    explanation offered by Mr. Demarest during questioning by sheriff’s deputies--that he had
    changed from a flannel shirt to a white shirt because he had a business meeting and
    thought that the white shirt looked better--was not credible. According to the
    prosecution, the real reason that Mr. Demarest changed shirts was that, after the fatal
    struggle with Mr. Hyams, Mr. Demarest’s shirt was covered with blood.
    8
    Finally, the prosecution pointed to several inconsistencies in Mr. Demarest’s
    statements to the sheriff’s deputies. It noted that Mr. Demarest had given conflicting
    answers concerning where he drove after leaving the dentist’s office and whether he knew
    the identity of Mr. Hyams’s realtor. The district attorney suggested that these
    inconsistencies indicated that Mr. Demarest had fabricated the entire account of his
    activities on the morning of February 9, 1981, in order to conceal the fact that he had
    murdered Mr. Hyams.
    As to a possible motive for the murder, the prosecution offered several
    explanations. At one point, it suggested that Mr. Demarest may have stolen some of Mr.
    Hyams’s jewelry and then hidden it in the house where jewelry was later discovered. The
    prosecution also suggested that Mr. Demarest may have been jealous of Mr. Hyams’s
    business success or upset because Mr. Hyams was planning to move to Boulder.
    However, the prosecution offered no evidence that Mr. Demarest was angry with Mr.
    Hyams.
    On behalf of Mr. Demarest, Mr. Cohan formulated a defense based on the
    contention that Mr. Hyams had been murdered by Margery Sheppard, a woman whom
    Mr. Hyams had rejected as a business partner. Mr. Cohan’s strategy was to call Ms.
    Sheppard as a witness at trial, question her about the murder, and then argue to the jury
    that she was the murderer. Apparently, despite discovering no evidence to support this
    theory, Mr. Cohan remained committed to it and did very little to prepare for trial. He
    9
    interviewed neither the prosecution’s expert witnesses nor Volunteer Fireman Davidson
    and Ms. Bausch, two important witnesses with regard to the scratches on Mr. Demarest’s
    hands. Additionally, Mr. Cohan did not listen to the tapes of the deputies’ interrogations
    of Mr. Demarest and never sought to obtain the records of Mr. Demarest’s psychiatric
    treatment immediately after the murder.
    At trial, Mr. Cohan was unable to pursue the theory that Ms. Sheppard was the
    murderer. After learning of Mr. Cohan’s plan to call her as a witness, Ms. Sheppard
    notified the judge that she would invoke her Fifth Amendment right not to testify. The
    judge then applied the Colorado law of privilege and ruled that Mr. Cohan would not be
    allowed to call Ms. Sheppard.
    Accordingly, Mr. Cohan called no witnesses in Mr. Demarest’s defense. During
    closing argument, he speculated that Mr. Hyams had been murdered by a person involved
    with drugs or by a spurned woman, but he was unable to point to any evidence supporting
    these contentions. Evidence introduced in post-conviction proceedings revealed that Mr.
    Cohan had never tried a felony case in state court and that his only criminal trial
    experience consisted of four or five federal misdemeanor cases involving the tax laws.
    Additionally, as his only investigator Mr. Cohan had hired a radio disc jockey with no
    relevant experience in criminal matters.
    On October 27, 1981, the jury convicted Mr. Demarest of the first-degree murder
    of Mr. Hyams. In December 1981, the court sentenced Mr. Demarest to life
    10
    imprisonment. Mr. Demarest appealed, and the Colorado Court of Appeals affirmed his
    conviction and sentence in May 1984. See 
    Demarest, 905 F. Supp. at 1441
    (citing State
    v. Demarest, No. 82 CA 122 (Colo. Ct. App. 1984)). The Supreme Court of Colorado
    denied certiorari. See 
    id. (citing State
    v. Demarest, No. 84 SC 295 (Colo. 1984)).
    In June 1985, Mr. Demarest filed a motion in the Jefferson County District Court
    for post-conviction relief pursuant to Rule 35(c) of the Colorado Rules of Criminal
    Procedure in which he argued that he had received ineffective assistance of counsel at
    trial. He was represented in the Rule 35(c) proceeding by a Deputy State Public
    Defender. The court conducted an evidentiary hearing on the motion, and Mr.
    Demarest’s counsel called three witnesses: Mr. Cohan, Charles Hoppin (an attorney), and
    Mr. Demarest. Mr. Cohan acknowledged that he committed a number of significant
    errors in representing Mr. Demarest at trial, including: failing to hire experienced co-
    counsel, failing to effectively argue for the suppression of Mr. Demarest’s statements to
    law enforcement officers on the grounds that they were not voluntarily made, failing to
    interview the state’s witnesses before trial, failing to effectively cross-examine the state’s
    blood-spatter expert, failing to consult his own blood-spatter expert, and failing to raise
    certain issues in a motion for a new trial. Mr. Hoppin testified that Mr. Cohan’s
    representation of Mr. Demarest fell below what should be expected of a reasonably
    competent defense attorney. He cited Mr. Cohan’s lack of experience in criminal trials,
    his failure to retain co-counsel, his failure to effectively argue for suppression of Mr.
    11
    Demarest’s statements to law enforcement agents, his failure to challenge the state’s
    blood-spatter expert, and his failure to hire an expert of his own. Mr. Hoppin opined that
    there was a reasonable probability that Mr. Cohan’s deficient performance affected the
    outcome of the trial. In his testimony at the Rule 35(c) hearing in the state court, Mr.
    Demarest described his dissatisfaction with Mr. Cohan’s representation and discussed his
    mental state during the interrogations by the deputy sheriffs. See Rec. vol. V, State v.
    Demarest, No 81-CR 259, vol. 3 (Tr. of Evidentiary Hr’g of Dec. 2, 1985).
    After considering this evidence, the district court issued a written ruling denying
    Mr. Demarest’s Rule 35(c) motion. Mr. Demarest appealed, the Colorado Court of
    Appeals affirmed the district court’s decision, see 
    id. vol. 2,
    at 302-303 (Unpublished Op.
    filed Apr. 7, 1988), and the Colorado Supreme Court denied certiorari, see 
    id. at 301
    (Order filed Dec. 19, 1988).
    In February 1989, Mr. Demarest filed a second Rule 35(c) motion in the Jefferson
    County District Court. The district court denied Mr. Demarest’s second motion, see 
    id. at 354-56
    (Order filed Mar. 8, 1989); the Colorado Court of Appeals affirmed, see State v.
    Demarest, 
    801 P.2d 6
    (Colo. Ct. App. 1990); and the Colorado Supreme Court denied
    certiorari, see 
    Demarest, 905 F. Supp. at 1442
    (citing Colorado v. Demarest, No. 90 SC
    439 (Order filed Nov. 19, 1990)).1
    1
    In this second motion, Mr. Demarest contended that: (1) he did not receive
    a constitutionally adequate competency hearing prior to trial; (2) exculpatory evidence
    was improperly excluded at trial; (3) on direct appeal of his conviction, the Colorado
    12
    In May 1991, Mr. Demarest filed in the United States District Court for the District
    Court of Colorado the instant petition for a writ of habeas corpus pursuant to 28 U.S.C. §
    2254. The federal petition combined the allegations of his first state post-conviction
    motion with many of the allegations of his second motion. In particular, Mr. Demarest
    alleged that: (1) he received ineffective assistance of counsel in violation of the Sixth and
    Fourteenth Amendments; (2) the Colorado Court of Appeals relied on matters not in the
    record in deciding his direct criminal appeal, thereby violating his Fifth and Fourteenth
    Amendment rights; (3) the Jefferson County District Court failed to hold an adequate
    hearing regarding his competency to stand trial, thus violating the Fifth and Fourteenth
    Amendments; (4) the Colorado Court of Appeals violated his Fifth and Fourteenth
    Amendment rights by reviewing the denial of the post-conviction motions without the
    complete record and without briefing or argument; (5) the Jefferson County District Court
    violated his Fifth and Fourteenth Amendment rights by refusing to consider the
    voluntariness of his statements to deputy sheriffs; and (6) the Colorado Court of Appeals
    violated his Fifth, Sixth, and Fourteenth Amendment rights by failing to remand his case
    for a new trial in light of a new decision.
    Court of Appeals improperly failed to apply recent law in violation of his constitutional
    rights by deciding the case without the full record; (4) cases decided during his direct
    appeal entitled him to a new trial; and (5) the prosecutor introduced unduly prejudicial
    evidence.
    13
    The federal district court assigned the case to a magistrate judge. Upon review of
    the record of the state court proceedings, the magistrate judge issued a recommendation
    concluding that the petition should be granted because Mr. Demarest had received
    ineffective assistance of counsel at the state murder trial in violation of the Sixth
    Amendment. A federal district court judge then reviewed this recommendation and
    remanded the case to the magistrate judge for further proceedings regarding the issue of
    whether Mr. Cohan’s acts and omissions prejudiced Mr. Demarest, “i.e., whether, but for
    [Mr.] Cohan’s errors, there was a reasonable possibility that the outcome of Demarest’s
    case would have been different.” 
    Demarest, 905 F. Supp. at 1443
    .
    In October 1994, the magistrate judge held an evidentiary hearing. In support of
    his ineffective assistance of counsel claim, Mr. Demarest called several witnesses who
    had not testified in the state court post-conviction proceedings. Dr. Richard Cohen, a
    colo-rectal surgeon, testified that he had performed hemorrhoid surgery on Mr. Demarest
    shortly before trial and had prescribed narcotics and tranquilizers for him. A cellmate of
    Mr. Demarest’s testified that he was in severe pain and took a great deal of medication
    during the period of the trial. Dr. Kathy Vedeal, a toxicologist, testified that the
    prescription drugs that Mr. Demarest was taking at the time of trial could have caused
    impaired mental ability, mental confusion, and decreased alertness.
    Mr. Demarest also introduced evidence at the hearing before the magistrate judge
    challenging the blood-spatter evidence offered by the prosecution at trial. Dr. Donald
    14
    Kennedy, a fluid dynamics expert, testified that there was no scientific basis for the
    inferences that Detective Hopkins drew from the pattern of blood stains at the murder
    scene.
    Mr. Demarest then introduced testimony from Eileen Bausch and Mark Davidson
    regarding the scratches on Mr. Demarest’s hands. Ms. Bausch testified that she must
    have seen Mr. Demarest’s hands at the dentist’s office. She added that during her
    testimony at Mr. Demarest’s trial in Jefferson County in 1981, she was nervous and her
    memory was cloudy. Ms. Bausch said because she misunderstood the prosecutor’s
    question at trial, she had incorrectly stated that she had not seen Mr. Demarest’s hands.
    She added that if Mr. Cohan had interviewed her prior to trial, she would have stated
    clearly in her trial testimony that there were no scratches on Mr. Demarest’s hands and
    face when he came into the dentist’s office.
    Similarly, Mark Davidson, the volunteer fireman who had spoken to Mr. Demarest
    in Mr. Demarest’s front yard on the day of the murder, testified at the evidentiary hearing
    that he had observed Mr. Demarest pounding his hands into the gravel. Like Ms. Bausch,
    Mr. Davidson said that if Mr. Cohan had interviewed him prior to trial, he would have
    testified at trial that Mr. Demarest had pounded his fists into the gravel.
    Mr. Demarest also presented testimony from Dr. William Rehg, one of the
    psychiatrists who treated him after the murder. Dr. Rehg stated that, in the days after the
    murder, Mr. Demarest suffered from adult situational reaction syndrome in response to
    15
    severe, acute stress and was treated with several medications. Finally, Mr. Demarest
    called Lee Foreman, a legal expert who testified that Mr. Cohan’s representation was
    constitutionally deficient and that, if Mr. Cohan’s mistakes had not occurred, the result of
    Mr. Cohan’s trial probably would have been different. Mr. Foreman focused on Mr.
    Cohan’s failure to argue for the suppression of Mr. Demarest’s statements to the police,
    his failure to present medical and psychiatric evidence to the jury to explain Mr.
    Demarest’s emotional reactions, his failure to challenge the state’s blood-spatter
    evidence, and his failure to interview witnesses before trial.
    After the evidentiary hearing, the magistrate judge issued a second
    recommendation concluding that Mr. Demarest had been deprived of his right to effective
    assistance of counsel and that his petition for a writ of habeas corpus should be granted.
    The federal district court agreed with the magistrate judge’s recommendation. The court
    first concluded that in pursing the theory that Ms. Sheppard was the real murderer,
    seeking to establish this fact by questioning her at trial, failing to interview the state’s
    witnesses, and failing to conduct any investigation of his own, Mr. Cohan’s
    representation of Mr. Demarest at trial “‘fell below an objective standard of
    reasonableness.’” Demarest, 905 F. Supp at 1446-50 (quoting Strickland v. Washington,
    
    466 U.S. 668
    , 687 (1984)). The district court then concluded that “[Mr.] Cohan’s failure
    to investigate the State’s case against [Mr.] Demarest, consider alternative defense
    theories, interview the Prosecution’s witnesses, and present the jury with medical
    16
    evidence relating to [Mr.] Demarest’s psychological state in the days following [Mr.]
    Hyams’ murder materially prejudiced [Mr.] Demarest.” 
    Id. at 1453.
    “Absent [Mr.]
    Cohan’s failings,” the court continued, “there is a reasonable probability that the outcome
    of [Mr.] Demarest’s trial would have been different.” 
    Id. at 1454.
    Accordingly, the court
    granted Mr. Demarest’s petition for a writ of habeas corpus. See 
    id. at 1456.
    II. DISCUSSION
    A. Application of the Antiterrorism and Effective Death Penalty Act
    As a preliminary matter, we must decide what version of the habeas corpus statutes
    to apply. Sections 101-06 of the Antiterrorism and Effective Death Penalty Act of 1996
    (AEDPA), Pub. L. No. 104-132, 110 Stat. 1214 (1996), signed into law on April 24,
    1996, amend §§ 2244 and 2253-55 of chapter 153 of Title 28 of the United States Code
    (federal statutes concerning habeas corpus proceedings). The state argues that this court
    should apply the AEDPA to Mr. Demarest’s habeas petition. Mr. Demarest responds that
    because his habeas petition was filed in the district court in 1991, well before the AEDPA
    was enacted, application of its provisions to this case would afford the statutory
    amendments an improper retroactive effect.
    The circuits have reached contrasting conclusions regarding the applicability of
    the AEDPA to cases filed before its effective date. In Edens v. Hannigan, 
    87 F.3d 1109
    ,
    1112 n.1 (10th Cir. 1996), this circuit concluded that the AEDPA did not apply to a non-
    17
    capital case in which the initial habeas petition was filed before April 24, 1996. See also
    Boria v. Keane, 
    90 F.3d 36
    , 38 (2d Cir. 1997) (per curiam) (concluding that the AEDPA
    does not apply to habeas petitions filed before April 24, 1996). In Lindh v. Murphy, 
    96 F.3d 856
    (7th Cir. 1996), rev’d, 
    117 S. Ct. 2059
    (1997), the Seventh Circuit disagreed,
    holding that the AEDPA should be applied to all pending cases.
    The Supreme Court granted certiorari in Lindh and resolved this conflict. 
    See 117 S. Ct. at 2062
    . The Court noted that, in contrast to the provisions concerning non-capital
    cases, Congress included a section in the AEDPA regarding capital cases that stated that
    it applied “‘to cases pending on or after the date of enactment of this Act.” 
    Id. at 2063
    (quoting AEDPA § 107(c)). Reading the AEDPA as a whole, the Court concluded that
    the Act “reveals Congress’s intent to apply the amendments to chapter 153 [regarding the
    habeas corpus statutes for non-capital cases] only to such cases as were filed after the
    statute’s enactment.” Id at 2063.2 As a result, the Court held that “the new provisions of
    chapter 153 generally apply only to cases filed after the [AEDPA] became effective.” 
    Id. at 2068.
    Mr. Demarest’s habeas petition was filed in the district court in 1991, well before
    the AEDPA’s April 24, 1996, effective date. Accordingly, we conclude that the AEDPA
    does not apply to these proceedings.
    2
    The Court did note that Congress did provide that a few specific sections of
    the AEDPA were applicable to pending non-capital cases. See 
    Lindh, 117 S. Ct. at 2063
    .
    None of those specific provisions was at issue in Lindh or in the instant case.
    18
    B. Exhaustion of State Remedies
    Under the doctrine of exhaustion, a state prisoner must generally exhaust available
    state court remedies before filing a habeas corpus action in federal court. See Picard v.
    Connor, 
    404 U.S. 270
    , 275 (1971); Hernandez v. Starbuck, 
    69 F.3d 1089
    , 1092-93 (10th
    Cir. 1995), cert. denied, 
    116 S. Ct. 1855
    (1996). At the time Mr. Demarest filed his
    habeas petition in the federal district court, the doctrine was codified at 28 U.S.C. §
    2254(b), which provided:
    :             An application for a writ of habeas corpus in behalf of a
    person in custody pursuant to the judgment of a State court
    shall not be granted unless it appears that the applicant has
    exhausted the remedies available in the courts of the State, or
    that there is either an absence of a State corrective process or
    the existence of circumstances rendering such process
    ineffective to protect the rights of the prisoner.
    The doctrine reflects the policies of comity and federalism between the state and federal
    governments, a recognition that “‘it would be unseemly in our dual system of government
    for a federal district court to upset a state court conviction without an opportunity to the
    state courts to correct a constitutional violation.’” 
    Picard, 404 U.S. at 275
    (quoting Darr
    v. Burford, 
    339 U.S. 200
    , 204 (1950), overruled on other grounds by Fay v. Noia, 372
    U.S. 391(1963)).
    The exhaustion doctrine requires a state prisoner to “fairly present[]” his or her
    claims to the state courts before a federal court will examine them. 
    Picard, 404 U.S. at 275
    ; see also Nichols v. Sullivan, 
    867 F.2d 1250
    , 1252 (10th Cir. 1989) (discussing fair
    19
    presentation requirement). “Fair presentation” of a prisoner’s claim to the state courts
    means that the substance of the claim must be raised there. The prisoner’s allegations and
    supporting evidence must offer the state courts “a ‘fair opportunity’ to apply controlling
    legal principles to the facts bearing upon his constitutional claim.” Anderson v. Harless,
    
    459 U.S. 4
    , 6 (1982) (citing 
    Picard, 404 U.S. at 276-77
    ). Therefore, although a habeas
    petitioner will be allowed to present “‘bits of evidence’” to a federal court that were not
    presented to the state court that first considered his claim, evidence that places the claims
    in a significantly different legal posture must first be presented to the state courts. Jones
    v. Hess, 
    681 F.2d 688
    , 694 (10th Cir. 1982) (quoting Nelson v. Moore, 
    470 F.2d 1192
    ,
    1197 (1st Cir. 1972)).
    In the instant case, the state argues that Mr. Demarest failed to exhaust his state
    remedies by failing to fairly present his ineffective assistance of counsel claim to the
    Colorado state courts. The state focuses on several witnesses at the federal evidentiary
    hearing: (1) Eileen Bausch and Mark Davidson who stated that, if they had been
    interviewed by Mr. Demarest’s attorney before his state court trial, they would have given
    testimony at the trial that directly supported Mr. Demarest’s assertion that he scratched
    his hands by pounding them onto the driveway after finding Mr. Hyams’s body; (2) Dr.
    Donald Kennedy, who challenged the scientific basis of the evidence offered at trial by
    the state’s blood-spatter expert; (3) Lee Foreman, the legal expert who testified at the
    federal evidentiary hearing that Mr. Cohan should have interviewed witnesses, presented
    20
    a blood-spatter expert like Dr. Kennedy to challenge the state’s evidence, and presented
    medical and psychiatric testimony to the jury to explain Mr. Demarest’s emotional
    breakdowns in the days after Mr. Hyams’s murder; and (4) Dr. Kathy Vedeal, a
    toxicologist, and Dr. William Rehg, a psychiatrist, who testified as to Mr. Demarest’s
    mental state during the period after Mr. Hyams’s murder. The state argues that these
    witnesses offered evidence at the federal evidentiary hearing that significantly altered Mr.
    Demarest’s ineffective assistance of counsel claim, placing it in a much stronger legal
    posture than in the state court proceedings. Because the Colorado state courts did not
    have an opportunity to consider this evidence, the state maintains, Mr. Demarest has
    failed to exhaust his state remedies by failing to present his ineffective assistance of
    counsel claims to the state courts.
    Mr. Demarest responds that, with regard to the testimony of Mr. Foreman and
    Drs. Kennedy, Vedeal, and Rehg, the state has waived the defense of failure-to-exhaust.
    He notes that the state failed to object to their testimony at the evidentiary hearing before
    the magistrate judge and did not challenge their testimony in its written objections to the
    magistrate judge’s findings and recommendations. As to Ms. Bausch and Mr. Davidson
    (whose testimony the state did challenge in the district court proceedings for failure-to-
    exhaust), Mr. Demarest contends that this evidence did not fundamentally alter his claim
    that his trial counsel was ineffective in failing to interview witnesses before trial. As a
    21
    result, he contends, the new testimony offered by these two witnesses at the federal
    evidentiary hearing does not contravene the exhaustion requirement.3
    1. The State’s Alleged Waiver
    The exhaustion requirement, although not to be lightly overlooked, is not
    jurisdictional. See Granberry v. Greer, 
    481 U.S. 129
    , 131 (1987); 
    Hernandez, 69 F.3d at 1092-93
    . As a result, there are circumstances in which a state may be deemed to have
    waived the exhaustion defense such that a federal court may consider the merits of a
    petitioner’s claims--even though those claims have not been fairly presented to the state
    3
    On appeal, Mr. Demarest also briefly argues that this court need not analyze
    the evidence presented at the federal evidentiary hearing because the evidence presented
    to the Jefferson County District Court in support of his motion for post-conviction relief
    under Colorado Rule of Criminal Procedure 35(c) is sufficient to establish that he
    received ineffective assistance of counsel pursuant to Strickland v. Washington, 
    466 U.S. 668
    , 687 (1984). See Aple’s Br. at 21-22. We are not persuaded by this argument.
    Although the evidence presented at the state court hearing provides ample support
    for the first element of the Strickland analysis, that trial counsel’s errors “fell below an
    objective standard of reasonableness,” 
    Strickland, 466 U.S. at 688
    , there is little concrete
    evidence in the state court record to establish the second Strickland element, that there is
    a “reasonable probability that, but for counsel’s unprofessional errors, the result of the
    proceeding would have been different.” 
    Id. at 694.
    In particular, the evidence presented
    by Mr. Demarest at the state court hearing does not establish what effect the interviewing
    of witnesses before trial and the presentation of expert witnesses by defense counsel at
    trial would have had on result of the murder case. Without evidence in the state court
    record as to how witnesses would have testified differently if they had been interviewed
    or as to what defense experts would have said to challenge the state’s scientific evidence,
    the prejudicial effect of trial counsel’s errors is highly speculative.
    In light of the insufficiency of the state court record, we must therefore proceed
    to analyze the evidence presented by Mr. Demarest at the federal evidentiary hearing and
    then to determine whether he has exhausted his state court remedies.
    22
    courts. See 
    Granberry, 481 U.S. at 131
    .4 In Granberry, the Supreme Court noted that
    when the state answers a habeas petition, it is obligated to advise the district court
    whether the petitioner has exhausted all available remedies. See 
    id. at 134.
    However, in
    instances in which the state has failed to raise a failure-to-exhaust defense in the district
    court proceedings, the courts of appeals may “take a fresh look at the issue,” determining
    “whether the interests of comity and federalism will be better served by addressing the
    merits forthwith or by requiring a series of additional state and district court proceedings
    before reviewing the merits of the petitioner’s claim.” 
    Id. In the
    instant case, the state has candidly conceded that its failure to object to the
    testimony of Mr. Foreman and Drs. Kennedy, Vedeal, and Rehg was “an unfortunate
    oversight.” See Aplt’s Opening Br. at 31. Moreover, we emphasize that, in order to
    afford the district court a reasonable opportunity to fairly adjudicate the relevant issues in
    the case, the defense of failure-to-exhaust should be raised as soon as reasonably possible,
    a practice that the state did not follow here when it specifically objected to only the
    Bausch and Davidson testimony at the federal hearing.
    4
    We note that the AEDPA amendments to 28 U.S.C. § 2254 change the
    Granberry rule with regard to cases filed after April 24, 1996. Under the amended
    version of § 2254(b)(3), “A State shall not be deemed to have waived the exhaustion
    requirement or be estopped from reliance upon the requirement unless the State, through
    counsel, expressly waives the requirement.” 28 U.S.C. § 2254 (b)(3) (1996). In the
    instant case, because Mr. Demarest filed his habeas petition in federal court in 1991, we
    apply Granberry rather than the amended version of § 2254(b)(3).
    23
    Nevertheless, considering the comity and federalism interests at issue in this case,
    we conclude for several reasons that the state’s failure to specifically object to the
    testimony of Mr. Foreman and Drs. Vedeal, Rehg, and Kennedy should not be deemed a
    waiver of the failure-to-exhaust defense as to these witnesses. First, unlike several of the
    decisions that have found a waiver of the defense, the state here did not completely fail to
    raise the issue before the district court ruled on the petition. See Hannon v. Maschner,
    
    981 F.2d 1142
    , 1146-47 (10th Cir. 1992) (declining to consider a failure-to-exhaust
    defense when the issue was not raised until oral argument on the motion to reconsider the
    order granting the writ); Stone v. Godbehere, 
    894 F.2d 1131
    , 1135 (9th Cir. 1990)
    (declining to consider the defense when the state failed to raise it at any point in the
    district court proceedings). Not only did the state object to the testimony of Ms. Bausch
    and Mr. Davidson (on the grounds that this testimony had not been presented to the state
    courts), but it also objected to the federal evidentiary hearing. See Rec. vol. I, doc. 46. In
    its objection, the state contended that because Mr. Demarest had been afforded an
    opportunity to develop his claims in the state court proceedings, an evidentiary hearing in
    the federal district court was improper. Although the state’s objection did not refer to the
    testimony of particular witnesses--a practice which would have been highly preferable if
    it sought to invoke the failure-to-exhaust defense--its contention that the state court
    record was sufficient to adjudicate Mr. Demarest’s claim and that new evidence should
    not be taken did raise the comity and federalism concerns on which the exhaustion
    24
    requirement is based. Accordingly, applying Granberry, we conclude that the state may
    now raise the failure-to-exhaust defense as to the referenced testimony of Mr. Foreman
    and Drs. Kennedy, Vedeal, and Rehg (as well as Ms. Bausch and Ms. Davidson). Cf.
    Caballero v. Keane, 
    42 F.3d 738
    , 741 (2d Cir. 1994) (rejecting argument that a habeas
    petitioner waived a failure-to-exhaust argument by failing to raise it in the federal district
    court proceedings because “[a]n important unresolved issue has not yet been considered
    by the state courts, and a procedure especially suited to air this issue is still available.”).
    2. Fair Presentation of Mr. Demarest’s Claims to the State Courts
    Because the state did not specifically raise the defense of failure to exhaust with
    regard to the testimony of Mr. Foreman and Drs. Vedeal, Rehg, and Kennedy, the district
    court did not consider the impact of that testimony on the issue of whether Mr.
    Demarest’s ineffective assistance of counsel claim had been fairly presented to the state
    courts. However, with regard to Ms. Bausch and Mr. Davidson, the district court agreed
    with Mr. Demarest that their testimony was “supplementary evidence of [Mr.] Cohan’s
    failure to investigate.” 
    Demarest, 905 F. Supp. at 1446
    . According to the district court,
    “The testimony [Ms.] Bausch and [Mr.] Davidson gave at the evidentiary hearing does
    not alter the nature of [Mr.] Demarest’s claim, nor does it significantly bolster the claim
    so as to substantially influence the ultimate determination of [Mr.] Demarest’s petition for
    writ of habeas corpus.” 
    Id. The district
    court found the Bausch and Davidson testimony
    25
    analogous to the new evidence presented to the federal district court in Vasquez v.
    Hillary, 
    474 U.S. 254
    (1986), which the Supreme Court characterized as not altering the
    nature of the habeas claim that had been presented to the state courts, see 
    id. at 260.
    See
    
    Demarest, 905 F. Supp. at 1446
    .
    In analyzing the parties’ arguments and the district court’s conclusions, we are
    guided by this circuit’s decision in Jones v. Hess, 
    681 F.2d 688
    (10th Cir. 1982), and by
    Fourth and Fifth Circuit decisions adopting similar reasoning, see Wise v. Warden,
    Maryland Penitentiary, 
    839 F.2d 1030
    (4th Cir. 1988); Dispensa v. Lynaugh, 
    826 F.2d 375
    (5th Cir. 1987). In Jones, the habeas petitioner asserted a claim that the trial judge
    was biased. In the federal court proceedings, the petitioner introduced three ex parte
    letters from the allegedly biased judge to the prosecutor concerning the petitioner’s case.
    The letters had not been introduced in the state court proceedings. This circuit concluded
    that the judge’s ex parte letters “transformed the claim of bias and prejudice into a
    significantly different and more substantial claim,” placing the claim “in a significantly
    different and stronger posture than it was when the state courts considered it.” 
    Jones, 681 F.2d at 693-94
    . The court therefore held that the petitioner’s bias claim was properly
    dismissed for failure to exhaust state court remedies. See 
    id. at 694.
    The Fourth and Fifth Circuits have adopted an approach similar to Jones in
    concluding that new evidence presented at a federal evidentiary hearing warranted
    dismissal of a habeas claim for failure to exhaust. In Wise, the habeas petitioner alleged
    26
    that the state had withheld exculpatory evidence that a witness who testified against him
    at trial had entered into an agreement with state. See 
    Wise, 839 F.2d at 1034
    . At the
    federal evidentiary hearing, the petitioner introduced for the first time the actual
    agreement between the state and the witness. The Fourth Circuit held that the agreement
    constituted new evidence that significantly altered the nature of the petitioner’s claims.
    As a result, the court concluded, the petition should be dismissed for failure to exhaust.
    “The state court, which has never been presented with this critical evidence, must be
    given the opportunity to evaluate the claim in its new posture and to make the relevant
    findings of fact to which the federal courts must in turn defer.” 
    Id. Similarly, in
    Dispensa, the habeas petitioner challenged the reliability of the
    victim’s in-court identification of him as well as the procedures used by police to elicit
    the victims’s pretrial, out-of-court identification. See 
    Dispensa, 826 F.2d at 376
    , 379. At
    the federal evidentiary hearing, the petitioner offered expert testimony from a
    psychologist regarding the victim’s choice of words and emotional state during the in-
    court identification. Additionally, in the federal hearing, the habeas petitioner described
    the out-of-court identification procedures in a manner that differed significantly from the
    description he had given in the state court proceedings. The Fifth Circuit held that the
    habeas petition should be dismissed for failure to exhaust because the petitioner’s
    changed testimony as well as the new expert testimony placed his claim in a significantly
    stronger posture than when he presented the claim to the state courts. See 
    id. at 379-80.
    27
    See also Joyner v. King, 
    786 F.2d 1317
    , 1320 (5th Cir. 1986) (noting that a petitioner who
    presents a weak case to the state court and a strong case to the federal court fails to satisfy
    the exhaustion requirement); Sampson v. Love, 
    782 F.2d 53
    , 54-55, 58 (6th Cir. 1984)
    (dismissing habeas petition for failure to exhaust when new evidence presented in the
    federal hearing showed that jurors knew about petitioner’s previous sentence); Brown v.
    Estelle, 
    701 F.2d 494
    , 495 (5th Cir. 1983) (“Where a federal habeas petitioner presents
    newly discovered evidence or other evidence not before the state courts such as to place
    the case in a significantly different and stronger evidentiary posture than it was when the
    state courts considered it, the state courts must be given an opportunity to consider the
    evidence.”); cf. Williams v. Washington, 
    59 F.3d 673
    , 677-79 (7th Cir. 1995) (concluding
    that the introduction of new evidence in federal court did not contravene exhaustion
    requirement because new evidence merely contained information that was available from
    other sources contained in the state court record).
    In the instant case, we apply the analysis followed by Jones and similar decisions
    to the new evidence offered by Mr. Demarest in the federal evidentiary hearing. As
    explained below, consideration of the testimony of the new witnesses leads us to conclude
    that Mr. Demarest’s ineffective assistance of counsel claim was not fairly presented to the
    state courts.
    28
    a. Testimony of Eileen Bausch and Mark Davidson
    In the state court hearing on his ineffective assistance of counsel claim, Mr.
    Demarest offered testimony from his trial counsel acknowledging that he had failed to
    adequately investigate the case and failed to interview certain witnesses. Although trial
    counsel listed particular witnesses that he failed to interview, he did not mention Ms.
    Bausch or Mr. Davidson.5 Moreover, at no point in the state post-conviction proceedings
    did Mr. Demarest even mention the testimony of Ms. Bausch or Mr. Davidson or contend,
    as he did so vigorously in the federal proceedings, that if Mr. Cohan had interviewed
    them prior to trial, they would have testified in a manner that would have substantially
    strengthened Mr. Demarest’s defense regarding the cause of the scratches on his hand.
    We disagree with the district court’s conclusion that “[Ms.] Bausch and [Mr.]
    Davidson’s testimony [at the federal evidentiary hearing] does not significantly change
    the nature of [Mr.] Demarest’s allegations.” Demarest, 905 F. Supp at 1446. Ms. Bausch
    and Mr. Davidson’s testimony constituted significant evidence that Mr. Cohan’s failure to
    interview them prejudiced Mr. Demarest’s defense. As the district court itself observed,
    Ms. Bausch testified at the federal hearing that had Mr. Cohan interviewed her before
    5
    Mr. Cohan listed the following witnesses that he failed to interview: Detective
    Hopkins (the state’s blood-spatter expert), the state’s pathologist, the medical personnel who
    treated Mr. Demarest at St. Anthony’s hospital, the personnel who drove Mr. Demarest to the
    hospital on the day of the murder and after he collapsed during the interrogation on February 12,
    1981, and the neighbor who waited with Mr. Demarest for emergency personnel to arrive. See
    Rec. vol. V, State v. Demarest, No. CR. 81-259, vol 3, at 17-19, 27 (Tr. of Evidentiary Hr’g of
    Dec. 2, 1985).
    29
    trial, he could have elicited from her testimony that she observed Mr. Demarest’s hands at
    the dental office on the morning of the murder but did not remember seeing scratches on
    his hands. In the words of Mr. Demarest’s legal expert in the federal proceedings, “the
    significance of [Ms. Bausch’s testimony] . . . can’t be over dramatized.” Rec. vol. III, at
    216 (Tr. of Evidentiary Hr’g of Oct. 17, 1994). Similarly, Mr. Davidson stated that if Mr.
    Cohan had interviewed him before trial, he would have testified that he remembered
    observing Mr. Demarest pounding his hands on the gravel driveway after discovering Mr.
    Hyams’s body. The testimony of both these witnesses supports the contention that more
    thorough pretrial preparation by Mr. Cohan would have uncovered evidence that very
    significantly strengthened Mr. Demarest’s defense. However, because this testimony was
    not presented in the state post-conviction proceedings, the state courts were deprived of
    the opportunity to assess the prejudicial effect of Mr. Cohan’s failure to interview Ms.
    Bausch and Mr. Davidson.
    We also disagree with the district court’s conclusion that “the introduction of the
    additional testimony is similar to the circumstances presented in Vasquez.” 
    Demarest, 905 F. Supp. at 1446
    . In Vasquez, in response to a request from a federal district court
    for evidence clarifying and supplementing the state court record, the petitioner submitted
    additional affidavits and a computer analysis to support the allegation that the state had
    improperly excluded African-Americans from a grand jury. See 
    Vasquez, 474 U.S. at 258-59
    . The Supreme Court held that the new evidence did not circumvent the
    30
    exhaustion requirement. As to the new affidavits, the Court noted that they were
    introduced to support allegations that were already supported by evidence in the state
    court record. As to the computer analysis, the Court said that it added nothing that was
    not intrinsic to any grand jury discrimination claim. See 
    id. at 260.
    Unlike the new evidence in Vasquez, the new evidence obtained from Ms. Bausch
    and Mr. Davidson does not merely supplement evidence in the state court record; it is
    more like a 180 degree turn. No evidence in the state court record indicates that a
    pretrial interview of these two witnesses by Mr. Demarest’s counsel would have produced
    credible testimony so highly favorable to his defense. Vasquez fails to support the district
    court’s conclusion that Ms. Bausch and Mr. Davidson’s new testimony did not
    significantly change the nature of Mr. Demarest’s allegations.
    b. Blood-spatter Evidence
    We reach the same conclusion as to the new testimony offered by Mr. Demarest
    regarding the state’s blood-spatter evidence. As noted above, in the state court
    proceedings, Mr. Demarest did allege that Mr. Cohan had failed to challenge the
    qualifications of Dr. Herbert MacDonell, the state’s first designated blood-spatter expert.
    Mr. Demarest also alleged that Mr. Cohan had failed to effectively cross-examine
    Detective Dick Hopkins, the witness who actually testified at the trial regarding the
    blood-spatter evidence. Additionally, Charles Hoppin, the legal expert who testified at
    31
    the state evidentiary hearing opined that Mr. Demarest’s trial attorney should have
    interviewed the state’s expert witnesses and should have consulted with an independent
    blood-spatter expert in order to properly evaluate and respond to the state’s evidence. See
    Rec. vol. V, State v. Demarest, No. CR 81-259, vol. 3 at 92-98 (Tr. of Evidentiary Hr’g of
    Dec. 2, 1985).
    However it was not until the federal evidentiary hearing that Mr. Demarest offered
    evidence from Dr. Donald Kennedy challenging the scientific basis of the state’s expert
    testimony. Dr. Kennedy began his testimony at the federal hearing by examining the
    manual on blood-spatter evidence written by Dr. MacDonell, the witness initially
    designated as the state’s expert. Detective Hopkins, the state witness who actually
    testified at trial regarding the blood-spatter evidence, attended Dr. MacDonell’s course
    and relied on his manual in reaching his conclusions. According to Dr. Kennedy’s
    testimony, the manual indicated that Dr. MacDonell lacked a basic understanding of the
    fluid dynamics of blood droplets.
    Dr. Kennedy proceeded to explain numerous specific errors in Dr. MacDonell’s
    manual. He criticized the experiments that it described, characterizing them as “poor high
    school science.” Rec. vol. II at 46 (Tr. of Evidentiary Hr’g of Oct. 17, 1994). He
    explained that Dr. MacDonell did not understand basic principles of fluid dynamics such
    as viscosity and surface tension. He described several measurements pertaining to the
    32
    fluid dynamics of blood droplets--the bond number, the Weber number, and the Reynolds
    number--and said that Dr. MacDonell lacked a basic understanding of these concepts.
    Then, Dr. Kennedy offered explanations of the ways in which Detective Hopkins’s
    trial testimony reflected Dr. MacDonell’s limited scientific understanding. He disagreed
    with Detective Hopkins’s statement that one could determine the type of weapon used by
    applying the principles of fluid dynamics to the blood droplets found at a crime scene. He
    also questioned Detective Hopkins’s opinions as to the sequence of events leading up to
    the murder, as to the type of weapon used, and as to the physical characteristics of the
    murderer (i.e. that the murderer was a strong, right-handed man), stating that fluid
    dynamics did not allow one to draw definitive conclusions about these matters.
    Essentially, Dr. Kennedy’s testimony regarding the state’s blood-spatter evidence
    was that the “physics are wrong, so the science is wrong, so the conclusions are wrong.”
    See Rec. vol. II at 64 (Tr. of Evidentiary Hr’g of Oct. 17, 1994). No evidence of this
    kind was presented in the state court proceedings. Thus, it was not until after Dr.
    Kennedy’s testimony in the federal court proceedings that Mr. Demarest could point to
    evidence that an adequate pretrial investigation by Mr. Cohan would have uncovered
    strong scientific evidence that could be used to challenge the state’s witnesses.
    Mr. Demarest’s new expert testimony from Dr. Kennedy resembles the new expert
    testimony offered by the petitioner in the Fifth Circuit’s decision in 
    Dispensa, 826 F.2d at 379-80
    . As in that case, the new evidence offered by Mr. Demarest through Dr. Kennedy
    33
    and Mr. Foreman transformed his claim from one involving only general allegations of
    failing to investigate and cross-examine and only a minimal showing of prejudice into one
    involving a concrete reference to a qualified expert who could have been produced at trial
    to rebut the scientific basis of the state’s case. We therefore conclude that Mr.
    Demarest’s allegations regarding his trial counsel’s failure to challenge the state’s blood-
    spatter evidence were not fairly presented to the state courts.
    c. Medical and Psychiatric Evidence
    We reach the same conclusion as to the medical and psychiatric evidence that Mr.
    Demarest produced at the federal evidentiary hearing to demonstrate how his mental state
    during the period shortly after Mr. Hyams’s murder could have been explained to the jury.
    At the federal hearing, Mr. Demarest presented three witnesses on this subject who did
    not testify in the state court proceedings: (1) Dr. Kathy Vedeal, a toxicologist, who
    testified about the effects of medication taken by Mr. Demarest after the murder and
    stated that the medication could have blurred his thinking; (2) Dr. William Rehg, a
    psychiatrist, who testified about Mr. Demarest’s mental state when Mr. Demarest was
    questioned by law enforcement officers and explained that Mr. Demarest’s highly
    emotional state could have been caused by feelings of shock and grief over the death of a
    friend; and (3) Lee Foreman, Mr. Demarest’s legal expert, who testified that Mr.
    Demarest’s trial counsel should have introduced medical and psychological evidence such
    34
    as that given by Drs. Vedeal and Rehg to explain why Mr. Demarest had difficultly giving
    consistent and coherent answers when he was interrogated. According to Mr. Foreman, a
    competent defense attorney could have used this evidence to rebut the prosecution’s
    contention that Mr. Demarest’s confused answers and emotional reactions reflected
    consciousness of guilt and to establish that Mr. Demarest had acted as would someone
    who had recently learned that a friend had been murdered. See Rec. vol. III at 269-272
    (Tr. of Evidentiary Hr’g of October 18, 1994).
    Like the new testimony of Ms. Bausch and Mr. Davidson and the new blood-
    spatter evidence, Mr. Demarest did not present this contention and supporting evidence to
    the state courts in the post-conviction proceedings. In the state proceedings, Mr.
    Demarest alleged that his trial counsel had failed to discover medical records that could
    have been used to challenge the voluntariness of his statements to the police, thereby
    providing the basis for a motion to suppress. However, Mr. Demarest never alleged in the
    state court proceedings that medical and psychiatric evidence could be used to explain his
    emotional state to the jury in a manner that supported his innocence. Thus, the testimony
    given by Drs. Vedeal and Rehg and by Mr. Foreman at the evidentiary hearing
    significantly strengthened Mr. Demarest’s contention that his trial counsel was ineffective
    in failing to present medical and psychiatric evidence to explain his emotional reactions to
    the jury. Thus, this aspect of Mr. Demarest’s ineffective assistance of counsel claim was
    also not fairly presented to the state courts.
    35
    In summary, like the new evidence offered in the federal proceedings in Jones,
    Wise, Dispensa, and similar cases, the new evidence submitted to the district court by Mr.
    Demarest transformed his ineffective assistance of counsel claim into one that was
    “significantly different and more substantial.” See 
    Jones, 681 F.2d at 693
    . In the state
    court proceedings, Mr. Demarest made general allegations concerning his trial counsel’s
    failure to investigate the case and interview witnesses. However, in the federal
    proceedings, those general allegations were supported by testimony of several witnesses
    concerning the prejudicial effect of his trial counsel’s deficient performance. Therefore,
    upon considering the new testimony of Ms. Bausch, Mr. Davidson and Mr. Foreman, and
    Drs. Kennedy, Vedeal, and Rehg, we conclude that Mr. Demarest has failed to exhaust his
    state court remedies regarding his ineffective assistance of counsel claim
    C. Procedural Bar
    Generally, when a habeas petitioner has failed to exhaust his state court remedies,
    a federal court should dismiss the petition without prejudice so that those remedies may
    be pursued. See 
    Jones, 681 F.2d at 694
    (affirming dismissal of habeas claim without
    prejudice for failure to exhaust); see also 
    Dispensa, 826 F.2d at 381
    (reversing the district
    court’s grant of a writ and remanding the case with instructions to dismiss without
    prejudice). However, in considering unexhausted claims, federal courts should consider
    whether, upon dismissal of the claims, the petitioner would then be able to raise them in
    36
    the state courts. “[I]f the court to which Petitioner must present his claims in order to
    meet the exhaustion requirement would now find those claims procedurally barred, there
    is a procedural default for the purposes of federal habeas review.” Dulin v. Cook, 
    957 F.2d 758
    , 759 (10th Cir. 1992) (citing Coleman v. Thompson, 
    501 U.S. 722
    , 735 n.1
    (1991)).
    Here, Mr. Demarest filed his ineffective assistance of counsel claim in the state
    courts pursuant to Rule 35 of the Colorado Rules of Criminal Procedure. Rule 35
    authorizes the state court to vacate a conviction that was imposed in violation of the laws
    or constitutions of the United States or Colorado. See Col. R. Crim. P. 35(c)(2)(I). Rule
    35(c)(3) provides in part that “[t]he court need not entertain a second motion or
    successive motions for similar relief based upon the same or similar allegations on behalf
    of the same prisoner.” Col. R. Crim. P. 35(c)(3). Accordingly, in order to determine
    whether Mr. Demarest would now be procedurally barred from bringing an ineffective
    assistance of counsel claim in state court based on the new evidence presented at the
    federal hearing, we must consider how the Colorado courts have interpreted Rule
    35(c)(3)’s prohibition of second and successive motions.
    The Colorado Supreme Court has held that “‘[w]here a post-conviction application
    is filed, it should contain all factual and legal contentions of which the applicant knew at
    that time of filing, and failure to do so will, unless special circumstances exist, ordinarily
    result in a second application containing such grounds being summarily denied.’”
    37
    Turman v. Buckallew, 
    784 P.2d 774
    , 780 (Colo. 1989) (en banc) (emphasis added)
    (quoting People v. Scheer, 
    518 P.2d 833
    , 835 (Colo. 1974)) (emphasis added); see also
    People v. Hubbard, 
    519 P.2d 945
    , 948 (Colo. 1974) (en banc) (“If a second or successive
    motion is filed, it may be summarily dismissed without a hearing unless the trial judge
    finds that the failure to include newly asserted grounds for relief in the first Crim. P.
    35(b) motion is excusable.”). Several Colorado decisions describe the kind of “special
    circumstances” that warrant the consideration of successive Rule 35 motions.
    The lack of counsel in post-conviction proceedings is one such special
    circumstance. The Colorado Supreme Court has held that “in the absence of a knowing
    and intelligent waiver, the assistance of counsel is essential in post-conviction
    proceedings, unless the asserted claim for relief is wholly unfounded.” 
    Hubbard, 519 P.2d at 948
    (citing Haines v. People, 
    454 P.2d 595
    (Colo. 1969) and Kostol v. People,
    
    447 P.2d 536
    (Colo. 1968)). Given the convicted defendant’s right to post-conviction
    counsel, the Colorado Supreme Court reasoned, it is possible for a full review of the
    defendant’s claims to be accomplished in a single post-conviction proceeding and “no
    justification exists for condoning successive and often repetitive motions for post-
    conviction relief.” 
    Id. In contrast,
    when a defendant represents himself pro se, he or she
    cannot reasonably be expected to raise all of his or her claims in a single proceeding. See
    
    id. (“The case
    law recognizes that as a practical matter without the assistance of counsel,
    a convicted defendant would be hard-pressed to assemble into a single Crim. P. 35(b)
    38
    motion all of the legal arguments which might result in post-conviction relief.”). As a
    result, Colorado courts have allowed defendants to file successive petitions after the
    denial of earlier petitions filed pro se. See, e.g., People v. Naranjo, 
    738 P.2d 407
    , 409
    (Colo. Ct. App. 1987) (“[S]ince [the] defendant did not have legal representation during
    the course of his first Crim. P. 35(c) proceeding, he is not necessarily precluded from
    relying upon other grounds for relief in his present motion.”).
    As the state here acknowledges, see Aplt’s Opening Br. at 30 n.7, another special
    circumstance that may warrant the consideration of a successive Rule 35 motion is the
    ineffective assistance of counsel in post-conviction proceedings. The Colorado Court of
    Appeals has held that the right to counsel in post-conviction proceedings includes the
    right to effective assistance of counsel under the standards established by the United
    States Supreme Court in 
    Strickland, 466 U.S. at 690
    . See People v. Hickey, 
    914 P.2d 377
    , 379 (Colo. Ct. App. 1995). As a result, the Court of Appeals concluded, the failure
    to provide effective assistance of counsel in a post-conviction proceeding is tantamount to
    failing to provide counsel at all. See 
    id. Hickey thus
    suggests that, like the complete
    absence of counsel in a post-conviction proceeding, ineffective assistance of counsel in
    such a proceeding may constitute a special circumstance that allows allow the court to
    consider a second or successive Colo. Crim. P. 35(c) motion. 
    Id. But see
    People v.
    Goldman, 
    923 P.2d 374
    , 374-75 (Colo. Ct. App. 1996) (refusing to follow procedure
    adopted in Hickey--remanding Rule 35(c) proceeding to the trial court to consider claim
    39
    alleging ineffective assistance of counsel in the Rule 35(c) proceeding--because this claim
    was not first raised in the trial court).
    In addition to the complete lack of counsel and ineffective assistance of counsel,
    the Colorado courts have suggested several other circumstances that may justify the
    consideration of successive post-conviction motions. For example, the announcement of
    a new legal principle after the first motion has been filed may warrant consideration of a
    successive motion. See People v. Allen, 
    843 P.2d 97
    , 101 (Colo. Ct. App. 1992)
    (“Because the defendant did not know of the changed double jeopardy legal standard
    when he filed his first Crim. P. 35(c) motion . . . his application for relief is not barred. . .
    .”), rev’d on other grounds, 
    868 P.2d 379
    (Colo. 1994). The discovery of new evidence
    may also constitute a special circumstance justifying consideration of a successive
    motion. See 
    Hubbard, 519 P.2d at 948
    .
    In the instant case, Mr. Demarest has offered no explanation as to why his counsel
    in the Rule 35(c) proceeding in state court did not present the significant new evidence
    that was subsequently produced at the federal hearing. Accordingly, we are unable to
    determine from the record before us whether Mr. Demarest’s failure to present this
    evidence in the state court proceedings was caused by the kind of “special
    circumstances,” see 
    Turman, 784 P.2d at 780
    ; 
    Scheer, 518 P.2d at 835
    , that would allow
    the filing of a second or successive post-conviction motion under Col. R. Crim. P. 35.
    (e.g., ineffective assistance of post-conviction counsel, the discovery of new evidence, or
    40
    a change in the law). We note that the state has requested that we remand the case to the
    district court for a determination of whether Mr. Demarest’s ineffective assistance of
    counsel claim based on the new evidence would be procedurally barred under Colorado
    law. In light of the insufficient record before us, we agree that remand is warranted to
    address that issue.6
    In the event that the district court finds that Mr. Demarest’s ineffective assistance
    of counsel claim (based on the new evidence discussed above) would not be procedurally
    barred under Colorado law, it should dismiss the claim without prejudice so that it may
    now be adjudicated in the Colorado courts. Alternatively, in the event that the district
    court finds that Mr. Demarest’s claim would be procedurally barred under Colorado law,
    6
    In his appellate brief, Mr. Demarest also argues that Colorado’s procedural
    rules should not bar federal habeas relief here because they have not been applied
    regularly and consistently by the state courts. See Aple’s Br. at 36-37. In order to
    preclude federal habeas review, a state’s procedural bar rules must be both “independent”
    and “adequate.” See Steele v. Young, 
    11 F.3d 1518
    , 1521-22 (10th Cir. 1993). A
    procedural bar rule is “independent” if it is based exclusively on state law. See 
    id. at 1521.
    Although it is often difficult to determine whether a procedural bar rule is
    “adequate,” we have concluded that “state procedural bar rules [are] inadequate to
    preclude federal review where the state court has not applied the bar ‘strictly or regularly’
    to the type of claim at issue.” 
    Id. at 1522
    (citing Gutierrez v. Moriarty, 
    922 F.2d 1464
    ,
    1469-71 (10th Cir. 1991)).
    Here, because the record does not indicate why Mr. Demarest did not
    present the testimony of Eileen Bausch, Mr. Davidson, and Drs. Vedeal, Kennedy, and
    Rehg in the initial state post-conviction proceedings, it is not clear whether Colorado’s
    procedural bar rules will apply to this case and, if they do apply, what particular rule will
    be triggered. Accordingly, we leave for the district court on remand the determination, if
    relevant, of whether the particular Colorado procedural bar rules at issue, if any, are
    sufficiently “adequate” and “independent” to preclude a successive ineffective assistance
    of counsel claim based on the new evidence.
    41
    the district court should proceed to determine the federal question of whether there was
    cause for the default and actual prejudice resulting from a violation of federal law or
    whether a failure to consider Mr. Demarest’s claim would result in a fundamental
    miscarriage of justice. See Breechen v. Reynolds, 
    41 F.3d 1343
    , 1353 (10th Cir. 1994).
    D. Cause and Prejudice; Fundamental Miscarriage of Justice
    A federal court may proceed to the merits of a procedurally defaulted habeas claim
    if the petitioner establishes either cause for the default and actual prejudice or a
    fundamental miscarriage of justice if the merits of the claim are not reached. Klein v.
    Neal, 
    45 F.3d 1395
    , 1400 (10th Cir. 1995); 
    Brecheen, 41 F.3d at 1353
    . The determination
    of cause and prejudice and of fundamental miscarriage of justice are both matters of
    federal law. See Murray v. 
    Carrier, 477 U.S. at 478
    , 489 (1984); 
    Klein, 45 F.3d at 1400
    .
    Cause for a procedural default generally involves “some objective factor external
    to the defense [that] impeded counsel’s efforts to comply with the State’s procedural
    rule.” 
    Murray, 477 U.S. at 488
    . Cause may be established by showing that “the factual or
    legal basis for a claim was not reasonably available to counsel” or that there was “‘some
    interference by officials that made compliance impracticable.” 
    Id. (quoting Brown
    v.
    Allen, 
    344 U.S. 443
    , 486 (1953)). However, ineffective assistance of counsel in the post-
    conviction proceedings does not constitute cause under federal law. See 
    Coleman, 501 U.S. at 757
    (1991) (“Because [petitioner] had no [federal constitutional] right to counsel
    42
    to pursue his appeal in state habeas, any attorney error that lead to the default of [his]
    claims in state court cannot constitute cause to excuse the default in federal habeas.”).7 If
    cause is established, the petitioner must then show that he suffered actual prejudice as a
    result of the alleged violation of federal law. See 
    Klein, 45 F.3d at 1400
    ; 
    Brecheen, 41 F.3d at 1353
    .
    Alternatively, a federal court may proceed to the merits of a procedurally defaulted
    claim if the petitioner establishes that a failure to consider the claim would result in a
    fundamental miscarriage of justice. See 
    Klein, 45 F.3d at 1400
    ; 
    Breechen, 41 F.3d at 1353
    . To come within this “very narrow exception,” 
    Klein, 45 F.3d at 1400
    , the
    petitioner must supplement his habeas claim with a colorable showing of factual
    innocence. See 
    id. Such a
    showing does not in itself entitle the petitioner to relief but
    instead serves as a “‘gateway’” that then entitles the petitioner to consideration of the
    merits of his claims. 
    Brecheen, 41 F.3d at 1357
    (quoting Herrera v. Collins, 
    506 U.S. 390
    , 404 (1993)). In this context, factual innocence means that “it is more likely than not
    that no reasonable juror would have found petitioner guilty beyond a reasonable doubt.”
    Schlup v. Delo, 
    513 U.S. 298
    , 327 (1995); see also 
    Murray, 477 U.S. at 496
    (“[W]e think
    7
    As noted above, under Colorado law (which the district court should apply
    to determine whether Mr. Demarest’s claim would now be procedurally barred),
    ineffective assistance of counsel in one collateral proceeding may authorize the filing of a
    second or successive proceeding. See 
    Hickey, 914 P.2d at 379
    . In this respect, the
    Colorado law that the district court must initially apply in determining whether there is a
    procedural bar differs from the federal law that must be applied if the district court finds a
    procedural bar and is then required to proceed to a determination of cause and prejudice.
    43
    that in an extraordinary case, where a constitutional violation has probably resulted in the
    conviction of one who is actually innocent, a federal habeas court may grant the writ even
    in the absence of a showing of cause for the procedural default.”). Factual innocence
    requires a stronger showing than that necessary to establish prejudice. 
    Schlup, 115 S. Ct. at 867
    . “[T]he habeas court must make its determination concerning the petitioner’s
    innocence ‘in light of all the evidence, including that alleged to have been illegally
    admitted (but with due regard to any unreliability of it) and evidence tenably claimed to
    have been wrongly excluded or to have become available only after the trial.’” 
    Id. (quoting Judge
    Henry Friendly, Is Innocence Irrelevant? Collateral Attack on Criminal
    Judgments, 38 U. Chi. L. Rev. 142, 160 (1970)).
    Accordingly, on remand, in the event that the district court finds that Mr.
    Demarest’s ineffective assistance of counsel claim based on the new evidence discussed
    above would be procedurally barred under Colorado law, it should then determine
    whether Mr. Demarest has established cause for the default and prejudice resulting from a
    violation of federal law or that a fundamental miscarriage of justice would result if his
    claim is not considered on the merits. In that event, if Mr. Demarest establishes either
    cause and prejudice or a fundamental miscarriage of justice, then the district court should
    grant his habeas petition.8
    8
    We note that although the state has challenged the district court’s
    conclusion that Mr. Demarest has exhausted his state court remedies, it has not
    challenged the district court’s conclusion on the merits that (in light of the new evidence)
    44
    II. CONCLUSION
    As the First Circuit has written:
    The junction where federal habeas power intersects with state criminal
    processes is enswathed in a mutuality of respect between sovereigns. It is
    that principle of comity which underlies the federal courts’ unwillingness to
    adjudicate too hastily matters of fundamental federal significance arising
    out of state prosecutions. Requiring that remedies be exhausted in state
    courts is merely comity’s juridical tool, embodying the federal sovereign’s
    respect for the state courts’ capability to adjudicate federal rights.
    Mr. Demarest received ineffective assistance of counsel in violation of the Sixth
    Amendment. “‘[A] legal decision made at one stage of litigation, unchallenged in a
    subsequent appeal when the opportunity to do so existed, becomes the law of the case for
    future stages of the same litigation, and the parties are deemed to have waived the right to
    challenge that decision at a later time.’” Capps v. Sullivan, 
    13 F.3d 350
    , 353 (10th Cir.
    1993) (quoting Williamsburg Wax Museum, Inc. v. Historic Figures, Inc., 
    810 F.2d 243
    ,
    250 (D.C. Cir. 1987)). Accordingly, in the event that the district court concludes that Mr.
    Demarest’s ineffective assistance of counsel claim (based on the new evidence) is
    procedurally barred but further finds either cause and prejudice or a fundamental
    miscarriage of justice, the district court’s decision on the merits of Mr. Demarest’s
    ineffective assistance of counsel claim will be the law of the case and his habeas petition
    should be granted.
    We further note that in granting the writ, the district court imposed certain
    conditions. In particular, the court ordered Mr. Demarest’s release upon either the
    expiration of sixty days from the entry of judgment or upon the commencement of state
    proceedings to retry him for Mr. Hyams’s murder, whichever was earlier. The court also
    ordered Mr. Demarest released on bond under certain conditions. See 
    id. at 1454-56.
                   In the event that the district court, through proceedings consistent with this
    opinion, again grants Mr. Demarest’s petition (i.e., by finding procedural bar and cause
    and prejudice or a fundamental miscarriage of justice), the determination of the
    conditions on which the writ should be granted and of the conditions of Mr. Demarest’s
    release will be a matter for the district court’s discretion.
    Finally, as the parties noted at oral argument, in light of its conclusion that
    he received ineffective assistance of counsel, the district court did not address Mr.
    Demarest’s other claims. See 
    Demarest, 905 F. Supp. at 1443
    , 1454. We leave it to the
    district court on remand to determine the appropriate disposition of these other claims.
    45
    Nadworny v. Fair, 
    872 F.2d 1093
    , 1096 (1st Cir. 1989) (citations omitted). In the instant
    case, that policy of comity, reflecting the mutuality of respect between state and federal
    courts, leads us to vacate an exceptionally well-reasoned opinion by the district court, one
    that forcefully expresses the fundamental importance of a defendant’s Sixth Amendment
    right to effective assistance of counsel in a criminal proceeding. We stress that our
    opinion in this case should not be read in any way as a criticism of the district court’s
    incisive analysis of the conduct of Mr. Demarest’s trial counsel. Moreover, it is
    noteworthy that in this appeal the state has not sought to defend that conduct, and we find
    it difficult to imagine how that conduct might be characterized any differently than did
    the district court--objectively unreasonable and materially prejudicial to Mr. Demarest.
    Nevertheless, these assessments of the conduct of Mr. Demarest’s counsel, as
    strongly supported as they are, may only be reached by considering important evidence
    not presented to the state courts in the post-conviction proceedings: the new testimony of
    Ms. Bausch and Mr. Davidson, the strong scientific evidence offered in support of Mr.
    Demarest’s defense by Dr. Kennedy, and the medical and psychiatric evidence from Drs.
    Vedeal and Rehg. Therefore, our respect for the state courts requires us to remand this
    case to the district court for a determination of whether this new evidence could now be
    presented in those courts. If Mr. Demarest’s new evidence may still be presented in the
    Colorado courts, then it is those courts, rather than the federal court, that should have the
    opportunity to initially consider it. That conclusion follows directly from the Supreme
    46
    Court’s statement that “‘it would be unseemly’” in our dual system of government to
    allow a federal court to overturn a state court conviction without affording the state courts
    an opportunity to correct a constitutional violation. See 
    Picard, 404 U.S. at 275
    (quoting
    
    Darr, 339 U.S. at 204
    ).9
    Therefore, we first conclude that the interests of comity and federalism support our
    consideration of the state’s failure-to-exhaust defense as to the new blood-spatter,
    medical, and psychiatric evidence offered by Mr. Demarest at the federal hearing. Upon
    reviewing this new evidence, as well as the new evidence offered by Ms. Bausch and Mr.
    Davidson at the federal hearing, we further conclude that Mr. Demarest did not fairly
    present his ineffective assistance of counsel claim to the Colorado courts and that he
    therefore failed to exhaust his state remedies. Accordingly, we vacate the decision of the
    district court and remand the case to the district court for a determination of whether Mr.
    Demarest would now be procedurally barred under Colorado law from bringing an
    ineffective assistance of counsel claim based on the new evidence.
    If the district court determines that Mr. Demarest’s ineffective assistance of
    counsel claim would not be procedurally barred, then it should dismiss the claim without
    prejudice so that it can now be considered by the Colorado courts. Alternatively, if the
    9
    In the event that Mr. Demarest’s ineffective assistance of counsel claim is
    returned to the state courts, we note that the testimony of the witnesses at the federal
    district court hearing may in certain circumstances be admissible in the state court
    proceedings. See Colo. R. Evid. 804 (b)(1) (establishing exception to hearsay rule for
    former testimony when declarant is unavailable).
    47
    district court finds that Mr. Demarest’s claim would now be procedurally barred, it should
    then determine under the applicable federal law whether Mr. Demarest can establish
    cause and prejudice for the procedural default or, alternatively, whether a fundamental
    miscarriage of justice would result from the failure to consider the merits of the claim
    because Mr. Demarest has made a colorable showing that he is factually innocent of the
    murder of Mr. Hyams. If Mr. Demarest makes such a showing of cause and prejudice or
    a fundamental miscarriage of justice, the district court should grant Mr. Demarest’s
    petition.
    We therefore VACATE the district court’s decision and REMAND the case to the
    district court for proceedings consistent with this opinion.
