[¶ 1.] Seventy-two former students of St. Paul’s School brought suit against four entities claiming that they were responsible for mental, physical and/or sexual abuse during the years 1947-1954 and 1958-1973. The circuit court granted summary judgment in favor of all defendants, concluding that a statute of limitations barred the claims. Thereafter, ten of the students moved to amend the complaint attempting to show a timely filing. Before the circuit court’s ruling on the motion to amend, nine of the students filed this appeal. Notwithstanding the filing of the appeal, the circuit court held a hearing on the merits and denied the motion to amend. The nine students now appeal the dismissal of their sex abuse claims and the denial of their motion to amend. We affirm in part, reverse in part, and remand.
I
[¶ 2.] The former students attended St. Paul’s School (School) in Marty, South Dakota, located on the Yankton Sioux Reservation. Students allege that the Catholic Diocese of Sioux Falls operated the School; and Blue Cloud Abbey, Sisters of the Blessed Sacrament, and the Oblate Sisters of the Blessed Sacrament provided teachers and staff. It is undisputed that in 1975, the School was closed as a Roman Catholic school and was relinquished to the tribal government of the Yankton Sioux *661 Tribe. The following year, the School’s assets were transferred to the Marty Indian School Board, Inc. No claim is made against the Tribe or the Marty Indian School Board.
[¶ 3.] The complaint provides no specifics, such as the names of the alleged abusers, when and where the abuse occurred, or the nature of the students’ claimed injuries. After some discovery, Defendants moved for summary judgment on the sex abuse claims 1 arguing that the statute of limitations had expired. The circuit court granted Defendants’ motion, concluding students did not present sufficient evidence that the “time the victim[s] discovered or reasonably should have discovered that the injury or condition was caused by the [abuse]” occurred within three years of commencing the suit as required in SDCL 26-10-25. The circuit court reasoned that Defendants’ initial showing reflected that the three-year statute had expired, and the students’ responsive affidavits failed to satisfy their burden of demonstrating a disputed issue of fact in avoidance of the statute of limitations defense. The court stated:
[A]s a matter of law, [Defendants] ha[ve] demonstrated that [students] have filed all their claims beyond the time allowed by ... 26-10-25 and, therefore, [students] have the burden of demonstrating that an exception to these statutes of limitations will excuse [their] untimely filing. Furthermore, the [c]ourt determines, as a matter of law, that [students] have failed to set forth specific facts in their Affidavits as required by SDCL 15-6-56(e) and have failed to present any evidence to support any exception to the applicable statute of limitations.
SDCL 26-10-25 is a “discovery” statute, and with respect to the students’ responsive showing regarding the discovery of their injuries, the circuit court elaborated:
The facts provided by the complaint, the interrogatory answers, depositions and affidavits are absolutely void of any specific information. The affidavits are boiler plate and generally set forth in conclusory fashion that the [students] discovered the condition resulting from the conduct within the last three years but does not detail specifically when the discovery was made; how the connection was made; and where this discovery took place. Because there is no specific factual information provided by the [students], SDCL 26-10-25 cannot provide an exception to the statute of limitations defense against the [students’] claims based on sexual abuse. 2
*662 The circuit court finally concluded that fraudulent concealment and estoppel by duress were not supported by the record, and that estoppel by duress was not a viable legal theory in South Dakota. Because the court dismissed the students’ claims on the statute of limitations, it did not consider the Diocese’s arguments that it had no control, supervision, or official relationship with the School, and that the students’ claims are barred by the constitutional principle of separation of church and state. The circuit court also did not address the Diocese’s and Oblate Sisters’ argument that SDCL 26-10-25 applies only to perpetrators and not third party entities who employed the alleged perpetrators.
[¶ 4.] After entry of the circuit court’s order dismissing all claims, ten students moved to amend the complaint in an attempt to show a timely filing by setting forth more specific facts. Before the circuit court’s ruling on this motion to amend, nine students filed this appeal. Notwithstanding the appeal, the circuit court held a hearing on the merits and denied the motion to amend. The court did not consider the question of its jurisdiction once a notice of appeal had been filed.
[¶ 5.] The nine students now appeal raising two issues:
Whether the circuit court erred in granting Defendants’ motion for summary judgment; and
Whether the circuit court erred in denying the students’ motion for leave to amend the complaint.
II
[¶ 6.] “Under our familiar standard of review in summary judgment cases, we decide only whether genuine issues of material fact exist and whether the law was correctly applied.”
Bordeaux v. Shannon County Sch.,
Ill
[¶ 7.] The issue in this appeal is whether students commenced their actions within the time allowed by SDCL 26-10-25. That statute provides:
Any civil action based on intentional conduct brought by any person for recovery of damages for injury suffered as a result of childhood sexual abuse shall be commenced within three years of the act alleged to have caused the injury or condition, or three years of the time the victim discovered or reasonably should have discovered that the injury or condition was caused by the act, whichever period expires later.
SDCL 26-10-25 (emphasis added).
[¶ 8.] As previously noted, the circuit court concluded that the students failed to carry their burden of establishing an exception to the statute of limitations. The court stated: Defendants “demonstrated that [students] have filed all their claims beyond the time allowed by ... [SDCL] 26-10-25 and, therefore, [students] have the burden of demonstrating that an exception to these statutes of limitations will excuse [their] untimely filing.” In reviewing this decision, we first discuss who had the summary judgment burden on this defense. 4 We then determine whether the party with that burden established entitlement to summary judgment.
[¶ 9.] SDCL 26-10-25 is an affirmative defense, and the burden of proof to establish affirmative defenses is on the party who seeks to rely on it.
Clancy v. Callan,
[¶ 10.] The Defendants failed to make that showing. The only evidence Defendants provided at this stage of the summary judgment proceeding was that: students acknowledged that the abuse happened decades ago when the School was allegedly operated and controlled by Defendants; some students acknowledged in discovery that they did not claim repressed memory of the abuse; and- the School was transferred to the Tribe in 1975. Although these facts were sufficient to make a presumptive showing that
some
of the students had been aware of the
abuse
for more than three years preceding the suit, it did not show that all of the students were aware of the abuse for the requisite period. More importantly, Defendants must have also introduced evidence presumptively showing that the students discovered or reasonably should have discovered that their injury or condition was caused by the abuse more than three years before commencing the suit. In our view, Defendants’ showing of knowledge of the abuse, coupled with cessation of control of the School, did not presumptively establish that students also discovered or reasonably should have discovered that their injury or condition was caused by the abuse. As noted in
Stratmeyer,
[¶ 11.] Because Defendants failed to make their initial presumptive showing that the students’ claims were not brought within the time allowed by the statute, the circuit court erred in shifting the burden to students to set forth specific facts to demonstrate their claims were timely. For the same reason, the sufficiency of the students’ responsive showing was immaterial at this stage of the summary judgment proceeding, and the circuit court erred in dismissing their claims.
[¶ 12.] There is, however, one student whose claim was correctly dismissed. Unlike the other eight students, Defendants made a presumptive showing that Orson Cuny was aware of the abuse and that his claimed injuries were causally related to the abuse more than three years before the suit was commenced. Cuny testified in his deposition that in the summer of 1982, he attended a treatment program at Sioux San Hospital in Rapid City, South Dakota to “seek help psychologically, spiritually.” He testified that during this psychological treatment, he “brought *665 this abuse out and above and surfaced it.” He further testified that in 1984, he chose to bring the events of the abuse to the forefront to try to cope with them.
[¶ 13.] An analogous situation was considered in
Frideres v. Schutz,
We agree with Frideres that mere knowledge of abuse will not necessarily start the running of the limitations period in every case. In this case, however, Frideres had enough knowledge linking the abuse and the resultant injuries, as evidenced by her visits to her family physician and priest in search of advice, to put her on inquiry notice more than two years prior to the commencement of this action. As the Supreme Court of Iowa stated, “ ‘the statute of limitations begins to run when a plaintiff first becomes aware of facts that would prompt a reasonably prudent person to begin seeking information as to the problem and its cause.’ ” At that time, a person is charged with knowledge of facts that would have been disclosed by a reasonably diligent investigation. Because Frideres remembered the abuse and was aware of enough of its effects to seek help more than two years prior to the commencement of her action, her action is time barred.
Id. (citations omitted).
[¶ 14.] We follow the same rule. In
Strassburg v. Citizens State Bank,
[¶ 15.] In this case, Cuny’s knowledge of the abuse, coupled with his psychological treatment for his condition, was sufficient to establish constructive
*666
knowledge of the abuse and that his injury was caused by that abuse. He was therefore on inquiry notice and was required to seek out further information and pursue his claim following his discoveries in 1982. Cuny, however, failed to commence his action within three years of that time. Considering the evidence of Cuny’s knowledge and treatment, the circuit court correctly concluded that Defendants satisfied their presumptive showing that the statute of limitations had expired and the burden of identifying specific facts in avoidance of the statute shifted to Cuny.
Conway,
[¶ 16.] Cuny claims that his cause of action was fraudulently- concealed by the Defendants. This Court has recognized fraudulent concealment as an implied exception to the statute of limitations, which acts to toll the statute of limitations until the cause of action is discovered or might have been discovered by the exercise of diligence.
One Star,
[¶ 17.] Cuny also asserts tolling of the statute of limitations under the equitable theory of estoppel by duress. He acknowledges that South Dakota has not recognized this exception to the statute of limitations. For purposes of this case, however, we may assume without deciding that the exception exists because Cuny did not make the responsive summary judgment showing necessary to establish entitlement to the exception. Where it has been adopted, the exception generally requires a showing that the duress be continuous.
See Overall v. Estate of Klotz,
[¶ 18.] In this case, Cuny identified no facts suggesting that any threats continued during the thirty years after he left the School. Consequently, even if we recognized the exception, he did not make the showing necessary to satisfy estoppel by duress.
IV
[¶ 19.] Diocese argues that even if the statute of limitations was incorrectly applied at this point in the proceedings, the Diocese should be dismissed because it had no control or supervision over the *667 School. Diocese also argues that its religious relationship with the School precludes intervention by a civil court because court involvement would result in an unlawful entanglement between church and state. Diocese and Oblate Sisters finally argue that SDCL 26-10-25 applies only to perpetrators of sex abuse and not third party entities who may only be vicariously responsible on theories other than those involving intentional acts.
[¶ 20.] The circuit court granted summary judgment solely on the statute of limitations, and it declined to address these additional issues. Because we have “reversed summary judgment on the issue of the statute of limitations, we need not decide th[ese] issue[s] now.”
Williams v. Maulis,
V
[¶ 21.] Students finally argue that the circuit court erred in denying their motion for leave to amend the complaint to set forth more specific allegations of the abuse. The circuit court did not consider this motion until after it entered its final judgment dismissing all claims and after the nine students appealed that judgment to this Court. Although such an appeal generally deprives the circuit court of jurisdiction to consider further substantive matters, the circuit court held a hearing on the students’ motion and determined that there was no basis to amend, their complaint after a final judgment had been issued.
[¶ 22.] We do not reach the circuit court’s analysis because it did not have jurisdiction to act upon the motion to amend. “An appeal from a judgment or order strips the trial court of power over the subject matter of the judgment or order, and this Court has jurisdiction until the appeal is decided.”
Matter of Hoffman,
VI
[¶ 23.] Because Defendants did not meet their presumptive burden of initially showing that eight of the students filed their claim beyond the statute of limitations period, the circuit court erred in shifting the burden to students and in considering the sufficiency of the students’ responsive showing. Therefore, with the exception of Cuny, the circuit court’s dismissal is reversed. The case of the remaining eight students is remanded for further proceedings consistent with this opinion.
Notes
. The circuit court dismissed all of the non-sex abuse claims, concluding that students failed to timely commence their suit on those claims in accordance with the personal injury statute of limitations in SDCL 15-2-14(3) (1984). That ruling has not been appealed.
. The circuit court's observation of the students' responsive showing was correct. These students, like the majority of the seventy-two plaintiffs in this case, submitted nearly identical affidavits resisting summary judgment. Only one affidavit was dated, and all contained the identical factual averments as the plaintiffs in
One Star v. St. Francis Mission,
This type of undated, identical, boilerplate affidavit is inadequate to meet the requirements of SDCL 15-6-56(e).
See Baatz v. Arrow Bar,
Nevertheless, as is discussed hereinafter, the students’ failure to respond with legally sufficient affidavits is of no consequence because the Defendants' showing in support of their motion for summary judgment was insufficient to shift the burden to students to specify facts supporting avoidance of the statute of limitations.
. We recognized this distinction in
Bordeaux,
stating, “those resisting summary judgment must show that they will be able to place sufficient evidence in the record at trial to support findings on all the elements on which they have the burden of proof.”
Bordeaux,
¶ 14,
. At one point in these proceedings, the circuit court stated that SDCL 26-10-25 was an exception to the general assault and personal injury statutes of limitations, and as an exception, the students had the initial burden of proof. SDCL 26-10-25 is not an exception to the general assault and personal injury statutes of limitations. Neither the title of the act nor the body of the enactment creating this statute suggest that it was an exception to other statutes of limitations. See 1991 SD Sess Laws ch 219 § 1. The circuit court, however, ultimately changed its view of SDCL 26-10-25. The court correctly concluded that Defendants carried the initial burden of presumptively showing that the students' claims were brought beyond the requirements of SDCL 26-10-25, and students only had the responsive burden of demonstrating an exception to this statute. See supra ¶ 3.
Defendants Blue Cloud Abbey and Oblate Sisters of the Blessed Sacrament also argue that SDCL 26-10-25 is not the applicable statute of limitations because that statute, enacted in 1991, did not exist at the time of the alleged abuse. Therefore, they assert that the statutes of limitations for personal injury and intentional torts apply, and the students’ claims are time-barred and cannot be revived. We held to the contrary in
Stratmeyer v. Strat-meyer,
concluding that the statute applied retrospectively, further stating that "[i]t is obvious from a plain reading of SDCL 26-10-25 ... that the Legislature intended SDCL 26-10-25 to apply to all acts of intentional childhood sexual abuse conduct.”
. Other cases that have recognized some form of the exception include
Bank of Penfield v. Colclough,
