This is a review of that part of a decision of the court of appeals,
State v. Pulizzano,
We conclude that Ms. Pulizzano was denied her constitutional rights to confrontation and compulsory process when the circuit court prohibited her from presenting evidence of the prior sexual assault of the child complainant for the limited purpose of establishing *639 an alternative source for M.D.'s sexual knowledge. Accordingly, we affirm the decision of the court of appeals. Because the case is remanded for a new trial and the second question may again be an issue, we further conclude that the circuit court abused its discretion in permitting the prosecutor's closing remarks.
Ms. Pulizzano was charged with the four counts of first degree sexual assault on November 12,1986. A preliminary examination was held on December 1, 1986, and she was bound over for trial. Prior to trial, Ms. Pulizzano requested the circuit court to permit cross-examination of M.D. regarding a prior sexual assault he had been the victim of two or three years earlier. Relying upon
State v. Padilla,
The prosecutor contended that Ms. Pulizzano failed to make an adequate offer of proof under Padilla because she failed to show sufficient similarity between the two sexual assaults to establish an alternative source for sexual knowledge. The prosecutor did not dispute that M.D. was the victim of an earlier sexual assault. The prosecutor disagreed, however, that M.D.'s testimony regarding what occurred in the previous incident would be the same as what Dr. Freund reported. The proper procedure, the prosecutor asserted, was to have M.D. examined in camera, and Ms. Pulizzano had not moved the court to do so.
The circuit court denied Ms. Pulizzano's request on the basis the evidence was excluded by the rape shield statute, sec. 972.11, Stats. The circuit court reasoned that even an adequate offer of proof under Padilla does not grant a defendant an "absolute" right to introduce evidence which otherwise would be excluded by the statute. The circuit court held that the relevance of M.D.'s prior sexual assault, if any, was substantially outweighed by considerations of unfair prejudice, confusion of the issues and misleading the jury, contrary to sec. 904.03, Stats. 1985-86. 3
At trial, M.D. testified that on August 30,1986, Ms. Pulizzano had sexual contact with him and three, other children, who ranged in age from three to five years old. Two were Ms. Pulizzano's own children, a daughter and *641 a son, while the other was, like M.D., Ms. Pulizzano's nephew. M.D., who was the only one of the children to testify, alleged that the sexual contact included fondling, fellatio, anal penetration with an object, and digital vaginal penetration. Afterwards, M.D. asserted, Ms. Puliz-zano threatened the children and told them not to tell anyone about the incident.
Ms. Pulizzano testified in her own defense and denied that she had sexual contact with the children. During the course of direct examination, Ms. Pulizzano asserted that she "would never ever do to those children what was done to me when I was little." While being cross-examined, Ms. Pulizzano further testified that as a child she had been sexually abused by her mother and sister, and that prior to that she had once been beaten and raped.
In reference to Ms. Pulizzano's testimony that she had been sexually abused as a child, the prosecutor in closing argued:
I think that, ladies and gentlemen, it's more likely when something like this has happened to you in the past when you were younger for when you've grown up to perpetuate the same type of conduct on innocent children.
Ms. Pulizzano objected to the prosecutor's argument at the time it was made and subsequently moved for a mistrial on that basis. The circuit court denied both the objection and the motion for mistrial on the ground the inference the prosecutor had drawn was "a matter of common knowledge."
On April 2, 1987, the jury returned a verdict convicting Ms. Pulizzano of all four counts, and a judgment of conviction was subsequently entered.
*642
Ms. Pulizzano appealed. The court of appeals reversed on the ground that Ms. Pulizzano's offer of proof established a "good faith" basis to cross-examine M.D. regarding the prior sexual assault.
Pulizzano,
The State petitioned this court for review, which was granted. Ms. Pulizzano did not seek cross-review of that part of the court of appeals' decision which upheld the circuit court's order excluding evidence of the alleged prior untruthful allegation of sexual assault made by M.D. We affirm that part of the court of appeals' decision reviewed and remand the case for a new tried.
The evidence Ms. Pulizzano sought to present was that M.D. had been the victim of a prior sexual assault which involved acts similar to those alleged here. Ms.
*643
Pulizzano does not contend here, nor did she in either court below, that evidence of the prior sexual assault is outside the scope of that barred by sec. 972.11, Stats. Both the circuit court and court of appeals held that the statute prohibited admission of the evidence. Although our review is independent of those courts,
State v. Sher,
We recognize that by so interpreting sec. 972.11(2)(b), Stats., our construction of the statute amounts to the same prohibition declared unconstitutional in
Herndon,
where the court of appeals struck down sec. 972.11(2)(c).
Herndon,
*645
The constitutional right to present evidence is grounded in the confrontation and compulsory process clauses of Article I, Section 7 of the Wisconsin Constitution and the Sixth Amendment of the United States Constitution.
See Washington v. Texas,
DECLARATION OF RIGHTS. . . . Rights of accused. SECTION 7. In all criminal prosecutions the accused shall enjoy the right ... to meet the witnesses face to face; [and] to have compulsory process to compel the attendance of witnesses in his behalf. . ..
The sixth amendment provides in pertinent part:
ARTICLE VI. In all criminal prosecutions, the accused shall enjoy the right ... to be confronted with the witnesses against him; [and] to have compulsory process for obtaining witnesses in his favor
The rights granted by the confrontation and compulsory process clauses are fundamental and essential to achieving the constitutional objective of a fair trial.
Chambers v. Mississippi,
We conclude that sec. 972.11, Stats., on its face does not violate a defendant's constitutional right to present evidence. We agree with the legislature's determination that generally evidence of a complainant's prior sexual conduct is irrelevant or substantially outweighed by its prejudicial effect. It is a view generally accepted by courts, legislatures, and legal writers alike, and nearly every state has enacted similar laws excluding such evidence upon that rationale. Based upon that premise, the evidence sec. 972.11 excludes does not fall within the scope of that constitutionally protected by a defendant's right to present evidence. Such a construction is consistent with the legislature's express declarations that relevant evidence not substantially outweighed by its prejudicial effect is generally admissible.
See
secs. 904.02,
4
*647
and 904.03, Stats. Because on its face the statute does not implicate a defendant's fundamental rights to confrontation and compulsory process, to withstand a constitutional challenge it need only be rationally related to a legitimate state interest.
See Rape Shield Statutes: Constitutional Despite Unconstitutional Exclusions of Evidence,
Despite the virtue of the general rule that such evidence is inadmissible, however, in the circumstances of a particular case evidence of a complainant's prior sexual conduct may be so relevant and probative that the defendant's right to present it is constitutionally protected. Section 972.11, Stats., as applied, may in a given case impermissibly infringe upon a defendant's rights to con
*648
frontation and compulsory process.
Cf. Chambers,
The State contends that only Ms. Pulizzano's right to confrontation is at issue. We disagree. Ms. Pulizzano's right to compulsory process is plainly at issue. The record reflects that Ms. Pulizzano requested the circuit court to permit Dr. Freund to testify at trial. The circuit court denied the request. Ms. Pulizzano's counsel then requested the circuit court to include in her offer of proof that Dr. Freund would testify to the contents of his report.
Our first inquiry is whether Ms. Pulizzano established that the evidence she sought to admit, that M.D. had experienced a prior sexual assault similar to those
*649
alleged here, was within the scope of that constitutionally protected by her rights to confrontation and compulsory process. The proper means for establishing that fact was an offer of proof. Padilla,
The State first argues the offer of proof failed to show that evidence of the prior sexual assault would be probative in establishing an alternative source for sexual knowledge. The State, relying upon Padilla, asserts that an in camera examination of M.D. was required to show the similarity between the two incidents. The State posits that showing cannot be made through evidence extrinsic to M.D.'s testimony, such as Dr. Freund's report. The State alternatively asserts that even if that showing can be made by extrinsic evidence, Dr. Freund's report failed to establish sufficient similarity between the prior sexual assault and those alleged here.
We disagree with the State that
Padilla
requires an
in camera
examination of M.D. as a prerequisite to Ms. Pulizzano's offer of proof. The court of appeals in
Padilla
only suggested that an
in camera
examination was one means by which the defendant in that case could have made an adequate offer of proof to support his contention.
Id.
at 430-31. The defendant there was convicted of having sexual contact with his girlfriend's ten-year old daughter. At trial, the defendant sought to introduce evidence of an alleged prior sexual assault the child suffered in order to rebut the inference that the child could not possess the explicit sexual knowledge she did unless the defendant sexually assaulted her. The defendant contended admission of the evidence was constitutionally required by
Davis.
The court of appeals
*650
recognized the validity of the inference the defendant sought to rebut and posited that under
Davis,
the evidence was potentially required to be admitted.
Padilla,
The State further argues that Ms. Pulizzano's offer of proof was insufficient because it failed to show several additional requirements set forth, in
Herndon.
In
Herndon,
the defendant sought to introduce evidence of the complainant's prior sexual conduct to show consent and a motive for fabricating the charges against him. The evidence consisted of testimony that the complainant had been arrested twice previously on prostitution charges. To gain admission of the other crimes, wrongs, or acts evidence, the court of appeals held that the defendant was required to make a six-part showing in his offer of proof.
Id.
at 129. The court of appeals held that the defendant must show that the prior acts clearly occurred; that the acts closely resembled those of the present case; that the prior act is clearly relevant to a material issue; that the evidence is necessary to the defendant's case; that the probative value of the evidence outweighs its prejudicial effect; and that there was a related pattern of behavior.
Id .
at 122-23. The State asserts that in addition to the first two tests, which are the same as those set forth in
Padilla,
Ms. Pulizzano's offer of proof should have satisfied the third, fourth and fifth
Herndon
tests. The court of appeals in this case rejected the
Herndon
tests because it determined they were not applicable where, as here, consent was not at issue.
Pulizzano,
We agree with the State that in a case of this type, a successful offer of proof must satisfy the first five of the six tests set forth in
Herndon.
Those five tests comport with the showing required by
Chambers
and
Davis
to establish a constitutional right to present evidence oth
*652
erwise excluded by a state evidentiary rule.
See Chambers,
We disagree with the State, however, that Ms. Pulizzano's offer of proof failed to satisfy the first five
Herndon
tests. An offer of proof "need not be stated with complete precision or in unnecessary detail but it should state an evidentiary hypothesis underpinned by a sufficient statement of facts to warrant the conclusion or inference that the trier of fact is urged to adopt."
Milenkovic v. State,
Having concluded that Ms. Pulizzano established a constitutional right to present evidence of the prior sexual assault M.D. experienced, it remains to be determined whether the State's interests in prohibiting the evidence nonetheless require that it be excluded. In an appropriate case, even though a defendant's right to present certain evidence is constitutionally protected, that right may have to "bow to accommodate other legitimate interests in the criminal trial process."
Chambers,
Courts and legal writers agree that the
Chambers
and
Davis
decisions set forth the standard to be applied for resolving questions pitting a state's interests in its evidentiary rules against a defendant's constitutional
*654
right to present evidence. But the courts and legal writers have disagreed on how those decisions are to be interpreted. Two general views have emerged. The first view merely requires a general balancing between the state's and defendant's interests.
See e.g., Rape Shield Statutes: Constitutional Despite Unconstitutional Exclusions of Evidence,
Our second inquiry, then, requires that the state's interests be closely examined and weighed against the
*655
force of the defendant's right to present the evidence, as measured by the first five
Herndon
tests. We conclude in this instance that Ms. Pulizzano's right to present the evidence must prevail.
Cf. Commonwealth v. Black,
We note that our conclusion that sec. 972.11, Stats., is unconstitutional as applied affects the validity of the statute only in this particular case.
Cf. Chambers,
We conclude, therefore, that the case must be remanded for a new trial. We find the harmless error rule is inapplicable. The rule is subsumed by the finding that exclusion of the evidence deprived Ms. Pulizzano of a
*656
necessary element of her defense.
See Constitutional Restraints on the Exclusion of Evidence in the Defendant's Favor: The Implications of Davis v. Alaska,
To summarize, we conclude that to establish a constitutional right to present otherwise excluded evidence of a child complainant's prior sexual conduct for the limited purpose of proving an alternative source for sexual knowledge, prior to trial the defendant must make an offer of proof showing: (1) that the prior acts clearly occurred; (2) that the acts closely resembled those of the present case; (3) that the prior act is clearly relevant to a material issue; (4) that the evidence is necessary to the defendant's case; and (5) that the probative value of the evidence outweighs its prejudicial effect. If the defendant makes that showing, the circuit court must then deter *657 mine whether the State's interests in excluding the evidence are so compelling that they nonetheless overcome the defendant's right to present it. In making that determination, the state's interests are to be closely examined and weighed against the force of the defendant's right to present the evidence, as measured by the first five Herndon factors. In this case, we conclude Ms. Puliz-zano's offer of proof was sufficient and that her right to present the evidence is paramount to the state's interests in excluding it. Accordingly, we affirm the court of appeals.
Because we remand the case for a new trial, the issue of the propriety of the prosecutor's remarks in closing argument may again arise and we therefore reach that question.
While counsel has wide latitude in closing arguments, the control of the content, duration of the argument, and the form of the closing argument are within the sound discretion of the trial court.
State v. Lenarchick,
We conclude that the circuit court abused its discretion in permitting the prosecutor to argue that because Ms. Pulizzano had been sexually abused as a child, she was more likely to have committed the alleged sexual assaults in this case. We disagree with the circuit court that the inference drawn by the prosecutor, known as the "battering parent syndrome,"
see generally
Bulleit,
The Battering Parent Syndrome: Inexpert Testimony as Character Evidence,
17 U. Mich. J.L. Ref. 653 (1984), is a matter of common knowledge. The admissibility of evidence of the battering parent syndrome has been controversial among the courts.
See id.
at 656-57. If admis
*658
sible at all, however, the courts have been uniform that it must be supported by expert testimony, both with respect to the theory itself and whether the defendant exhibits character traits consistent with that profile.
See, e.g., Sanders v. State,
We note that generally the State would be precluded from presenting evidence of the battering parent syndrome in its case-in-chief by sec. 904.04(1), Stats. 1985-86. 5 In this case, however, Ms. Pulizzano's testimony that she "would never ever do to those children what was done to me when I was little" opened the door to the State's rebutting her claim. See sec. 904.04(1)(a). We conclude that the prosecutor's argument in closing was improper, however, because it was unsupported by expert testimony. We offer no opinion as to whether evidence of the battering parent syndrome properly supported by expert testimony would be admissible in rebuttal. The absence of expert testimony in this case precludes our resolving that issue.
By the Court. — The decision of the court of appeals is affirmed; and cause remanded for a new trial and further proceedings not inconsistent with this opinion.
