This is an appeal from an order of the Dane County Circuit Court, Robert R. Pekowsky, Circuit Judge, in a proceeding under sec. 974.06, Stats.,1 to vacate a judgment of conviction or, in *171the alternative, order a new trial for defendant Bárbaro Escalona-Naranjo (Escalona-Naranjo). Escalona-Naranjo argued that his conviction resulted from a denial of his state and federal right to effective assistance of counsel under art. I, secs. 7 and 8 of the Wisconsin Constitution2 and the sixth and fourteenth *172amendments to the United States Constitution.3 By order dated March 9, 1992, the court dismissed Escalona-Naranjo's amended sec. 974.06 motion. The court concluded that each of the issues raised in Escalona-Naranjo's motion had been raised in initial postconviction motions to the circuit court, and on appeal. As such, a motion under sec. 974.06 could not be used to review issues which were or could have been litigated on direct appeal.
The court of appeals certified Escalona-Naranjo's appeal from the circuit court decision to this court, pursuant to sec. (Rule) 809.61, Stats.
*173The issue in this case is whether Escalona-Naranjo is prohibited from raising his claim of ineffective assistance of trial counsel in a postconviction motion under sec. 974.06, Stats., if such a claim could have been raised in a previously filed sec. 974.02 motion and/or on direct appeal. We conclude that Escalona-Naranjo could have raised the ineffective assistance of trial counsel claim in postconviction motions under sec. 974.02, Stats.4 Therefore, we hold that Escalona-Naranjo is precluded from raising that issue in a sec. 974.06 motion. We now affirm the order of the circuit court dismissing Escalona-Naranjo's sec. 974.06 motion.
In December, 1984, a criminal complaint was filed, charging Escalona-Naranjo with two counts of possession of controlled substances with intent to deliver, in violation of secs. 161.14(4)(n), 161.14(4)(t), and 161.41(lm)(b), Stats. 5 Escalona-Naranjo was convicted of both counts following a jury trial in February, *1741986. Though the initial date for sentencing was to occur in May, 1986, trial counsel filed a motion to vacate the conviction and requested an inquiry as to Esealona-Naranjo's mental condition. A competency hearing was held in August of that year, wherein Escalona-Naranjo was determined to be competent for sentencing.
Following Esealona-Naranjo's sentencing in September, 1986, defense counsel filed a notice of intent to seek postconviction relief. See sec. 809.30(2)(b), Stats. Pursuant to sec. 974.02, Stats., postconviction motions for a new trial, competency redetermination, and resentencing were filed in December, 1986.
In July, 1987, the circuit court issued a memorandum decision denying Esealona-Naranjo's motion to vacate the judgment and order a new trial. The court stated that the "defendant has failed to show the existence of error sufficient to justify an order vacating the *175judgment and granting a new trial. Nor has defendant shown that the cumulative impact of the challenged evidentiary decisions was sufficiently prejudicial to require grant of defendant's motion."
After the court of appeals affirmed the judgment of the circuit court, Escalona-Naranjo filed a sec. 974.06, Stats., motion in July, 1990. An amended motion was filed in February, 1991. Escalona-Naranjo claimed relief because his conviction resulted from a denial of his right to effective assistance of trial counsel under art. I, secs. 7 and 8 of the Wisconsin Constitution and the sixth and fourteenth amendments of the United States Constitution. Specifically, Escalona-Naranjo argued that certain evidence and testimony admitted at trial should have been objected to by trial counsel and that the failure to object resulted in a waiver of the right to appeal on these issues.
The state, in its motion to summarily dismiss Escalona-Naranjo's sec. 974.06 motion, argued that all of the alleged errors claimed had been previously raised in the 1986 postconviction motion and on appeal. The state contended that merely rephrasing the issues submitted on appeal would not constitute the basis for a sec. 974.06 motion.
The circuit court adopted the reasoning of the state and dismissed the sec. 974.06 motion. Escalona-Naranjo sought further review by the court of appeals. Certifying the case to this court, the court of appeals stated that even though Escalona-Naranjo waived certain evidentiary issues because he did not object at trial, the sec. 974.06 motion may have raised new issues not decided on direct appeal.
This case involves the construction of sec. 974.06, Stats. A question of statutory construction is a question *176of law which this court decides independently and without deference to the reasoning of the lower courts. Pulsfus Farms v. Town of Leeds, 149 Wis. 2d 797, 803-04, 440 N.W.2d 329 (1989) (citing Sacotte v. Ideal-Werk Krug & Priester, 121 Wis. 2d 401, 405, 359 N.W.2d 393 (1984), and Ball v. District No. 4, Area Board, 117 Wis. 2d 529, 537, 345 N.W.2d 389 (1984)). See also City of Muskego v. Godec, 167 Wis. 2d 536, 545, 482 N.W.2d 79 (1992) (with the construction of a statute, an appellate court is not bound by a trial court's conclusions of law and decides the matter de novo).
PURPOSE OF SECTION 974.06, STATS.
With the exception of subsection (4), sec. 974.066 is a direct adaptation of 28 U.S.C. sec. 2255.7 The federal statute attempted to provide "an expeditious remedy for correcting erroneous sentences without resorting to habeas corpus." Angela B. Bartell, Comment, Wisconsin Post Conviction Remedies — Habeas Corpus: Past, Present and Future, 1970 Wis. L. Rev. 1145, 1152 [hereinafter Wisconsin Post Conviction Remedies]. See also U.S. Code Congr. Serv. 1248 (1949) (Act of May 24, 1949). In fact, as applied in Wisconsin, the postconviction motion procedure under sec. 974.06 was "designed to replace habeas corpus as the primary method in which a defendant can attack his conviction after the time for appeal has expired." Howard B. Eisenberg, Post-Conviction Remedies in the 1970's, 56 Marq. L. Rev. 69, 79 (1972).
In 1972, this court stated that
*177[t]he postconviction motion under sec. 974.06, Stats., is not a substitute for a motion for a new trial. A sec. 974.06 motion can be made only after the defendant has exhausted his direct remedies which consist of a motion for a new trial and appeal. A sec. 974.06 motion is limited in scope to matters of jurisdiction or of constitutional dimensions. The motion must not be used to raise issues disposed of by a previous appeal.
Peterson v. State, 54 Wis. 2d 370, 381, 195 N.W.2d 837 (1972) (footnote omitted). See also Nichols v. State, 73 Wis. 2d 90, 241 N.W.2d 877 (1976); Sass v. State, 63 Wis. 2d 92, 216 N.W.2d 22 (1974).
By contrast, the language of subsection (4) of sec. 974.06 was adapted from the Uniform Post-Conviction Procedure Act. See 11 U.L.A. 477 (1974). First approved in 1955 by the National Conference of Commissioners on Uniform State Laws and the American Bar Association, it was revised by the same bodies in 1966. The primary purpose of the act was to compel a prisoner to raise all grounds regarding postconviction relief in his or her original, supplemental or amended motion, thereby cutting off successive frivolous motions.8 See sec. 8 of the uniform act [Waiver of *178Claims]; see also Wisconsin Post Conviction Remedies, 1970 Wis. L. Rev. at 1153. In 1980, the new Post-Conviction Procedure Act was approved and superseded the 1966 version. The substance of sec. 8 is now embodied in sec. 12 [Affirmative Defenses-Res Judicata-Misuse of Process].
Though Wisconsin did not formally adopt the Uniform Post-Conviction Procedure Act, the purpose underlying the original sec. 8 was incorporated into sec. 974.06(4). Contrary to the assertion of the dissent in this case, the purpose of sec. 974.06(4) is clear: to require criminal defendants to consolidate all their postconviction claims into one motion or appeal.9
ESCALONA-NARANJO 'S SECTION 974.06 MOTION WAS PROPERLY DISMISSED
Escalona-Naranjo argues that neither the circuit court nor the court of appeals directly addressed any claim that trial counsel's failure to object to the admission of certain evidence or testimony at trial resulted in ineffective assistance of counsel. As a result, he contends that the claim of ineffective assistance of trial counsel in the sec. 974.06 motion should not be pre-*179eluded because it is being raised now for the first time and is a distinct issue from those previously considered. In his sec. 974.02 motion for postconviction relief, requesting a new trial, Escalona-Naranjo alleged that he was deprived of his due process right to a fair trial, in part, for the following reasons:
(1) The court improperly admitted testimony regarding a search warrant, which evidence was overly prejudicial to the defendant and consisted of impermissible hearsay;
(2) The court improperly permitted substantial inadmissible hearsay to be used against the defendant;
(3) The court permitted the introduction of substantial evidence of other crimes which were not relevant and which were prejudicial to the defendant;
(4) The court improperly admitted the testimony of police officers regarding matters beyond their competence; and
(5) The court improperly permitted the introduction of extrinsic evidence of the credibility of a confidential informant, in violation of sec. 906.08(2), Stats.
However, in the circuit court's memorandum decision and order, these challenges were directly addressed. In each case, the court noted that either (a) the defendant failed to show that evidence was improperly admitted or (b) no objection was made at trial to the introduction of certain testimony or evidence. The court concluded that the failure to raise a timely objection operated as a waiver of any future challenge to the evidence.
Additionally, it must be noted that two companion postconviction motions were filed on the same day as the motion for a new trial. Those motions called for a competency redetermination or, in the alternative, *180resentencing. In each of those motions, Escalona-Naranjo specifically alleged that he was denied effective assistance of counsel at his competency hearing and his sentencing but never alleged ineffective assistance of his trial attorney.10
Escalona-Naranjo argues that any failure to raise the issue of ineffective assistance of counsel in his sec. 974.02 motion for a new trial or on direct appeal does not constitute a waiver, because the issue is one of constitutional dimension. Escalona-Naranjo looks to this court's decision in Bergenthal v. State, 72 Wis. 2d 740,242 N.W.2d 199 (1976), as controlling.
During his trial for first-degree murder, Bergen-thal requested an in camera inspection of materials possessed by the state, which he claimed were exculpatory. Upon review, the circuit court concluded the materials were not exculpatory and had them sealed in a brown envelope for subsequent appeal purposes. Id. at 746. During postverdict motions, Bergenthal raised 100 claims of error and, for a second time, challenged the failure of the court to disclose the contents of the envelope. On appeal, 99 claims of error were raised, but not the circuit court's failure to disclose the contents of the envelope. Id. at 745-46. Though the court's ruling on the exculpatory nature of the materials in the envelope was not challenged on direct appeal, the materials themselves were not transferred to this court for review when direct appeal was taken. Id. at 746.
After this court affirmed Bergenthal's 'conviction, he challenged the denial of access to the allegedly exculpatory materials in a sec. 974.06 motion. The cir*181cuit court denied the motion, stating that the issue had been disposed of on direct appeal and that, therefore, "the motion could not be used as a vehicle for a second appeal on grounds already reviewed." Id. at 745. This court disagreed and stated that
[e]ven though the issue might properly have been raised on appeal, it presents an issue of significant constitutional proportions and, therefore, must be considered in this motion for postconviction relief.
Id. at 748.
We now overrule the holding in Bergenthal which stated that although a defendant fails to raise a constitutional issue on appeal, the issue still must be considered when raised in a subsequent sec. 974.06 motion. The plain language of subsection (4) clearly provides when a sec. 974.06 motion is appropriate. First, all grounds for relief under sec. 974.06 must be raised in a petitioner's original, supplemental, or amended motion. Contrary to statements by the dissent, there is no legislative history which restricts "original, supplemental or amended motion" to a motion brought solely under sec. 974.06. Further, such a conclusion could not be reached even if we were to look to the drafting language of section 8 of the Uniform Post-Conviction Procedure Act.
Second, if the defendant's grounds for relief have been finally adjudicated, waived or not raised in a prior postconviction motion, they may not become the basis for a sec. 974.06 motion. The language of subsection (4) does not exempt a constitutional issue from this limitation, unless the court ascertains that a "sufficient reason" exists for either the failure to allege or to ade*182quately raise the issue in the original, supplemental or amended motion.11
*183Even if the Bergenthal court was aware, as the dissent asserts,12 that the origin of subsection (4) was distinct from the rest of sec. 974.06, it failed to properly address the fact that it was designed as a means to compel a prisoner to consolidate all grounds for relief, including constitutional grounds, in his or her original, supplemental or amended motion.13
Additionally, the Bergenthal decision appears to rely on Loop v. State, 65 Wis. 2d 499, 502, 222 N.W.2d 694 (1974), wherein this court stated: "Issues of constitutional dimension can be raised on direct appeal and can also be raised on 974.06 motions." We note, how*184ever, that although the defendant in Loop filed a sec. 974.06 motion requesting a new trial, he had not previously filed a sec. 974.02 motion or pursued a direct appeal. As a result, no ground for relief had been either raised or finally adjudicated in an earlier postconviction motion or appeal. In Loop, this court simply held that "where a direct appeal is not taken, a defendant is [not] foreclosed from raising an alleged error of constitutional dimension in a sec. 974.06 motion . . .." Id. at 502.
In contrast, Bergenthal did appeal, raising 99 claims of error but not challenging the circuit court's ruling on the allegedly exculpatory materials in the sealed envelope. By failing to properly apply sec. 974.06(4), the Bergenthal court allowed the defendant to raise that one remaining issue in a sec. 974.06 motion.
As applied in the instant case, subsection (4) clearly does not preclude Escalona-Naranjo from raising, even at this time, an issue of constitutional dimension which for sufficient reason was not asserted or was inadequately raised in his original, supplemental or amended postconviction motions. However, Escalona-Naranjo raised the issue of ineffective assistance of counsel in two of his sec. 974.02 motions. At the same time, he already knew that his trial attorney had failed to object to what he believed to be inadmissible evidence. He chose not to make that allegation in those motions and has not alleged any sufficient reason why a court should now entertain that same claim in a sec. 974.06 motion.
The dissent criticizes this decision because "it treats direct appeals and motions under sec. 974.06 identically in interpreting sec. 974.06(4). They are not to be treated the same for purposes of sec. 974.06(4)." *185Dissenting op. at 190. However, the dissent cites no authority for that proposition. The plain language of sec. 974.06(4) states that "[a]ny ground... not so raised . . . in the proceeding that resulted in the conviction or sentence or in any other proceeding the person has taken to secure relief may not be the basis for a subsequent motion . . .." (Emphasis added.) Again, nowhere in the statute is it stated that a sec. 974.06 motion should be treated differently from a direct appeal or a sec. 974.02 motion.
We need finality in our litigation. Section 974.06(4) compels a prisoner to raise all grounds regarding postconviction relief in his or her original, supplemental or amended motion. Successive motions and appeals, which all could have been brought at the same time, run counter to the design and purpose of the legislation.
Contrary to the assertion of the dissent, we are not foregoing fairness for finality nor do we abdicate our responsibility to protect federal constitutional rights. We simply apply the plain language of subsection (4) which requires a sufficient reason to raise a constitutional issue in a sec. 974.06 motion that could have been raised on direct appeal or in a sec. 974.02 motion. The dissent fails to explain why it is now unfair to tell Escalona-Naranjo, or other criminal defendants and their attorneys, that constitutional claims which could have been raised on direct appeal or in a sec. 974.02 motion cannot later be the basis for a sec. 974.06 motion.
Section 974.08(4) was not designed so that a defendant, upon conviction, could raise some constitutional issues on appeal and strategically wait to raise other constitutional issues a few years later. Rather, the defendant should raise the constitutional issues of *186which he or she is aware as part of the original postcon-viction proceedings. At that point, everyone's memory is still fresh, the witnesses and records are usually still available, and any remedy the defendant is entitled to can be expeditiously awarded.
In its motion to dismiss Escalona-Naranjo's sec. 974.06 motion, the state's written argument to the circuit court began: "When are these cases ever completed? It appears that as long as some lawyer can come up with a new theory the appeals continue." During the process of filing a series of sec. 974.02 postconviction motions in 1986, Escalona-Naranjo had available to him a complete record of the trial and postverdict proceedings. He claimed ineffective assistance of the counsel who handled the competency and sentencing hearings but chose not to raise that same issue with respect to his trial attorney. We conclude that he has not alleged a sufficient reason as to why his allegation of ineffective assistance of trial counsel could not have been raised when he filed his sec. 974.02 motion for a new trial. The circuit court properly dismissed his motion.
By the Court. — The order of the circuit court is affirmed.
Section 974.06, Stats., reads as follows:
974.06 Postconviction procedure. (1) After the time for appeal or postconviction remedy provided in s. 974.02 has expired, a prisoner in custody under sentence of a court or a person convicted and placed with a volunteers in probation program under s. 973.11 claiming the right to be released upon the ground that the sentence was imposed in violation of the U.S. constitution or the constitution or laws of this state, that the court was without jurisdiction to impose such sentence, or that the sentence was in excess of the maximum authorized by law or is otherwise subject to collateral attack, may move the court which imposed the sentence to vacate, set aside or correct the sentence.
(2) A motion for such relief is part of the original criminal action, is not a separate proceeding and may be made at any time.
The supreme court may prescribe the form of the motion.
(3) Unless the motion and the files and records of the action conclusively show that the person is entitled to no relief, the court shall:
(a) Cause a copy of the notice to be served upon the district attorney who shall file a written response within the time prescribed by the court.
(b) If it appears that counsel is necessary and if the defendant claims or appears to be indigent, refer the person to the state public defender for an indigency determination and appointment of counsel under ch. 977.
(c) Grant a prompt hearing.
(d) Determine the issues and make findings of fact and conclusions of law. If the court finds that the judgment was rendered without jurisdiction, or that the sentence imposed was not authorized by law or is otherwise open to collateral attack, or that there has been such a denial or infringement of the constitutional rights of the person as to render the judgment vulnerable to collateral attack, the court shall vacate and set the judgment aside and shall discharge the person or resentence him or her or grant a new trial or correct the sentence as may appear appropriate.
(4) All grounds for relief available to a person under this section must be raised in his or her original, supplemental or *171amended motion. Any ground finally adjudicated or not so raised, or knowingly, voluntarily and intelligently waived in the proceeding that resulted in the conviction or sentence or in any other proceeding the person has taken to secure relief may not be the basis for a subsequent motion, unless the court finds a ground for relief asserted which for sufficient reason was not asserted or was inadequately raised in the original, supplemental or amended motion.
(5) A court may entertain and determine such motion without requiring the production of the prisoner at the hearing. The motion may be heard under s. 807.13.
(6) Proceedings under this section shall be considered civil in nature, and the burden of proof shall be upon the person.
(7) An appeal may be taken from the order entered on the motion as from a final judgment.
(8) A petition for a writ of habeas corpus or an action seeking that remedy in behalf of a person who is authorized to apply for relief by motion under this section shall not be entertained if it appears that the applicant has failed to apply for relief, by motion, to the court which sentenced the person, or that the court has denied the person relief, unless it also appears that the remedy by motion is inadequate or ineffective to test the legality of his or her detention.
Article I, secs. 7 and 8 of the Wisconsin Constitution provide in relevant part as follows:
Rights of accused. Section 7. In all criminal prosecutions the accused shall enjoy the right to be heard by himself and counsel; to demand the nature and cause of the accusation against him; to meet the witnesses face to face; to have compulsory process to compel the attendance of witnesses in his behalf; and in prosecutions by indictment, or information, to a speedy public trial by an impartial jury of the county or district wherein the offense shall have been committed; which county or district shall have been previously ascertained by law.
*172Prosecutions; double jeopardy; self-incrimination; bail; habeas corpus. Section 8. . . . (1) No person may be held to answer for a criminal offense without due process of law, and no person for the same offense may be put twice in jeopardy of punishment, nor may be compelled in any criminal case to be a witness against himself or herself.
The sixth amendment to the United States Constitution reads:
In all criminal prosecutions, the accused shall enjoy the right to a speedy and public trial, by an impartial jury of the State and district wherein the crime shall have been committed, which district shall have been previously ascertained by law, and to be informed of the nature and cause of the accusation; to be confronted with the witnesses against him; to have compulsory process for obtaining witnesses in his favor, and to have the Assistance of Counsel for his defence.
The fourteenth amendment, sec. 1, provides:
All persons bom or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside. No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any State deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.
Section 974.02, Stats., provides in relevant part:
974.02 Appeals and postconviction relief in criminal cases. (1) A motion for postconviction relief other than under s. 974.06 by the defendant in a criminal case shall be made in the time and manner provided in ss. 809.30 and 809.40. An appeal by the defendant in a criminal case from a judgment of conviction or from an order denying a postconviction motion or from both shall be taken in the time and manner provided in ss. 808.04(3), 809.30 and 809.40....
(2) An appellant is not required to file a postconviction motion in the trial court prior to an appeal if the grounds are sufficiency of the evidence or issues previously raised.
Section 161.14(4)(n), Stats., lists phencyclidine, commonly known as "POP," as an hallucinogenic drug and controlled substance.
Section 161.14(4)(t), Stats., lists tetrahydrocannabinols, commonly known as "TCH," as an hallucinogenic controlled *174substance. It is contained in marijuana, obtained from marijuana or chemically synthesized.
Section 161.41(lm)(b), Stats., reads as follows:
161.41 Prohibited acts A — penalties....
(lm) Except as authorized by this chapter, it is unlawful for any person to possess, with intent to manufacture or deliver, a controlled substance. Intent under this subsection may be demonstrated by, without limitation because of enumeration, evidence of the quantity and monetary value of the substances possessed, the possession of manufacturing implements or paraphernalia, and the activities or statements of the person in possession of the controlled substance prior to and after the alleged violation. Any person who violates this subsection with respect to:
(b) Except as provided in pars, (c), (cm) and (e) to (h), any other controlled substance classified in schedule I, II or III, may be fined not more than $15,000 or imprisoned for not more than 5 years or both[.]
Section 974.06 was enacted as ch. 255, sec. 63, Wis. Laws of 1969, effective July 1,1970.
Enacted June 25, 1948, ch. 646, 62 Stat. 967; amended May 24,1949, ch. 139, sec. 114, 63 Stat. 105.
In the Commissioners' Prefatory Note, the rationale for the proposed uniform act was discussed. Of great concern was the increased federal-state conflict resulting from the use of a federal habeas corpus writ by state prisoners. Abuses which had arisen in connection with federal habeas corpus would, according to the commissioners, be eliminated by means of constructive action at the state level. Thus, the Uniform Post-Conviction Procedure Act was designed in part to (1) provide a single, unitary, postconviction remedy to be used in place of other state remedies; (2) provide a remedy for all grounds for attacking the validity of a conviction or sentence in a criminal case; and (3) require the applicant to present all claims for *178attack on the conviction or sentence at the initial postconviction proceeding, unless sufficient reason was given as to why a ground for relief was not raised or adequately asserted at that proceeding. See 11 U.L.A. at 479-82.
At the time of the 1966 revision of the Uniform Post-Conviction Procedure Act, the Commissioners' Prefatory Note articulated a similar intent:
[The act] requires an applicant to present all of his claims for attack on his conviction or sentence in his initial post-conviction proceeding....
11 U.L.A. at 481.
The parties subsequently stipulated to the granting of postconviction relief in the form of a de novo sentencing hearing. Thereafter, Escalona-Naranjo withdrew his postconviction motion with regard to a competency redetermination.
In State v. Klimas, 94 Wis. 2d 288, 288 N.W.2d 157 (Ct. App. 1979), the defendant filed a sec. 974.06 motion and appeal challenging the constitutionality of his conviction for first-degree murder. Klimas claimed that the circuit court's refusal to allow psychiatric testimony regarding his mental state at the time of the murder and the refusal to submit a manslaughter instruction to the jury deprived him of due process of law. Id. at 291. The court of appeals held that
[a] defendant's failure to raise the issue on direct appeal was not a 'knowing, voluntary and intelligent waiver' within the meaning of the statute, and that he had a 'sufficient reason' for failing to assert them at that time. Moreover, the issues presented on this appeal are issues of significant constitutional magnitude.
Id. at 299 (footnote omitted).
We overrule that part of Klimas which relied on the Bergen-thal conclusion that all constitutional issues must be considered in postconviction relief proceedings. However, at the time of Klimas' direct appeal, this court had not yet decided the case of Schimmel v. State, 84 Wis. 2d 287, 267 N.W.2d 271 (1978). Schimmel followed the case of Hughes v. Matthews, 576 F.2d 1250 (7th Cir. 1978), which held that the exclusion of psychiatric testimony regarding a defendant's mental capacity to form the intent to kill, coupled with a jury instruction stating the defendant is presumed to have intended the natural and probable consequences of his acts, unconstitutionally relieves the state of its burden of proving intent beyond a reasonable doubt. The exclusion of such testimony deprived the defendant of his sixth and fourteenth amendment rights to present a defense. Under Hughes and Schimmel, the psychiatric evidence in Kli-mas should have been admitted. Klimas, 94 Wis. 2d at 296-97.
Since the effect of subsequent law was not foreseen at the time of the appeal, a "sufficient reason" existed as to why certain issues were not raised in the earlier motion.
The dissent would have us assume that the presence of Justice Connor Hansen at a November, 1969, meeting of the Judicial Council Criminal Procedure Code Revision Committee subsequently validated the court's reasoning in Bergenthal. Dissenting op. at 188-189. Though Justice Hansen stated at the meeting that this court favored "some kind of omnibus postcon-viction remedy," the legislative history from which this decision is drawn is devoid of any further comment by him regarding an understanding of the scope or limitations imposed by subsection (4).
Subsection (4) was incorporated as a part of sec. 974.06 by ch. 255, sec. 63, Wis. Laws of 1969, effective July 1, 1970. A comparable limiting provision was not incorporated into 28 U.S.C. sec. 2255 until September, 1976, effective February, 1977. Rule 9(b) of the rules governing sec. 2255 proceedings for the United States district courts states:
Successive motions. A second or successive motion may be dismissed if the judge finds that it fails to allege new or different grounds for relief and the prior determination was on the merits or, if new and different grounds are alleged, the judge finds that the failure of the movant to assert those grounds in a prior motion constituted an abuse of the procedure governed by these rules.
(As amended Pub. L. 94-426, sec. 2(9), (10), Sept. 28, 1976, 90 Stats. 1335).
