Opinion by
In this medical malpractice case, plaintiffs, Lance and Theresa Erskine, appeal the judgment entered on a jury verdict in favor of defendants, Gloria Beim, M.D., and Alpine Orthopaedics & Sports Medicine, P.C., on the basis that the trial court improperly struck one of their expert witnesses for failure fully to disclose testimonial history. Defendants conditionally cross-appeal, in the event we reverse, on the basis that the trial сourt improperly struck three of their expert witnesses, two for failure fully to disclose testimonial history and one for other reasons. We reverse and remand for a new trial at which all experts stricken for failure to disclose testimonial history shall be allowed to testify, but subject to other sanctions that the court may impose, if any.
*227 I. Background
During trial, plaintiffs moved to preclude testimony from two defense experts for incomplete disclоsure of testimonial history, relying on several court of appeals decisions, including Trattler v. Citron,
During the pendency of this appeal, the supreme court announced Tratéler II, which held that "preclusion оf expert witnesses for failure to provide testimonial history is a disproportionate sanction."
We agree with plaintiffs that Trattler II should be applied retroactively, that they are not precluded from relying on it by their position below, and that it requires the judgment be reversed and the case remanded for a new trial at which all experts stricken for failure fully to disclose their testimonial histories shall be allowed to testify.
II. Retroactivity
We first address and reject defendants' contention thаt we should depart from the general rule that judicial decisions are applied retroactively. Martin Marietta Corp. v. Lorenz,
To determine whether Trattler II should be given only prospective effect, we apply a three-part test: first, the decision must establish a new principle of law; see-ond, the merits of each case must be weighed by looking to whether retrospective application will further or retard thе purpose and effect of the rule in question; and third, the inequity imposed by retroactive application must be weighed to avoid injustice or hardship. See Marines v. Indus. Comm'n,
A. New Rule of Law
To establish a new rule of law, a judicial decision must either resolve an issue of first impression not clearly fоreshadowed by prior precedent or overrule clear past precedent on which the litigants may have relied. Id.
Here, the following statements in Trattler II suggest that it did not establish a new rule of law:
The Trattler II majority stated that the trial court had "misread C.R.C.P. 37(c)(1)"182 P.3d at 683 . It did not find that C.R.C.P. 37(c)(1) was ambiguous. Rather, it interpreted Rule 37 by looking to the plain language. See Curlin v. Regional Transp. Dist.,983 P.2d 178 , 180 (Colo.App.1999) ("the supreme court's decision ... merely determined" whаt "the plain language of [the statute]" required); Jaimes v. State Farm Mut. Auto. Ins. Co.,53 P.3d 743 , 747 (Colo.App.2002)("In a case of first impression before it, the supreme court in DeHerrera [v. Sentry Ins. Co.,30 P.3d 167 (Colo.2001)] interpreted § 10-4-609(1), an unambiguous statute ... The court did not overrule any of its prior precedent, nor did it resolve an issue of first impression not clearly foreshadowed by prior precedent. ...").
e The Trattler II majority did not overrule its prior cases interpreting Rule 37(c)(1), Cook v. Fernandez-Rocha,168 P.3d 505 (Colo.2007), and Todd v. Bear Valley Vill Apartments,980 P.2d 973 (Colo.1999), but rather distinguished them because "the evidence that was precluded was the evidence that was not disclosed." *228182 P.3d at 681 . See Curlin,983 P.2d at 180 ("the court noted that its decision was consistent with the result reached in two prior decisions by different divisions of this court.").
e The Trattler II majority also stated, "We reaffirm the principle that sanctions should be directly commensurate with the prejudice caused to the opposing party."182 P.3d at 682 (emphasis added). See Rocky Mountain Power Co. v. Colorado River Water Conservation District,646 P.2d 383 , 389 (Colo.1982) (a new rule of law is not created if a decision reaffirms the holdings of prior decisions}.
In contrast to these statements, when discussing the court of appeals decisions in Woznicki v. Musick,
These court of appeals decisions were final. Compare Williams v. Trailmobile, Inc.,
Thus, because the first factor is not free of doubt, we consider the second and third factors. See Martin Marietta Corp. v. Lorenz,
B. Further or Retard Operation
We conclude that retroactive application of Trattler II furthers its operation.
The Trattler II majority emphasized that "it is unreasonable to deny a party an opportunity to present relevant evidence based on a draconian application of pretrial rules."
These statements show that retroactive application of Trattler II would further its purpose by allowing parties who have been precluded from presenting relevant expert testimony, based on incomplete disclosure of the expert's testimonial history, the opportunity to present such testimony at retrial. Cf. People in Interest оf C.A.K.,
C. Injustice or Hardship
We also conclude that retroactive application of Tratétler II will not result in injustice or hardship.
In People in Interest of C.A.K.,
[There are two justifications for a denial of retroactive effect. The first is the protection of persons who have relied on the earlier state of the law; the second is the protection of stability in areas where society attaches particular importance to stability.
[[Image here]]
The reliance factor is more persuasive when the change in the law at issue concerns pre-litigation conduct that becomes the subject of later litigation, because most acts, onee done, cannot be undone ... Here, the conduct that is governed by the change in the law can be undone. The case could be remanded for a new trial, and the parties would then begin again at square one.
*229
See also Cash v. Califano,
Here, applying Traitler II retroactively neither bars claims nor undercuts vested rights. Rather, the parties would be allowed to present additional relevant expert testimony that was improperly stricken. Further, retroactive application of Trattler II will not erode any stability interests. See People in Interest of C.A.K.,
Defendants fail to show any hardship created by retroactive application. See Marinez,
Instead, they argue that because plaintiffs "created the situation they now complain of" it would be inеquitable-and therefore unjust-for them to take the opposite position on appeal. For the reasons discussed in Section III below, however, we discern nothing inequitable per se in allowing a party on appeal to obtain the benefits of a post-trial supreme court decision.
Moreover, applying Trattler II retroactive-Ty benefits all parties. As also discussed in Section III below, two of defendants' experts who were stricken based on failure to disclose testimonial history shall be allowed to testify on retrial. Thus, while defendants face the risk of an adverse outcome on retrial, because this factor is common to all retroactive applications it cannot establish hardship or injustice in the absence of vested rights or stability interests as discussed above.
Accordingly, we conclude that the three-part test for detеrmining retroactive application of a judicial decision requires us to apply Trattler II here.
III. Invited Error
We next address and reject defendants' contention that the doctrines of invited error and judicial estoppel preclude plaintiffs from relying on Trattler ILI.
The judicial estoppel doctrine requires "parties to maintain a consistency of positions in the proceedings, assuring promotion of truth and preventing the parties from deliberately shifting positions to suit the exigencies of the moment." Estate of Burford v. Burford,
The invited error doctrine prevents a party from inducing an erroneous ruling and then seeking to benefit by appealing that error. A party's affirmative action during litigation triggers this doctrine and usually bars appellate review of any alleged error arising from such action. Vista Resorts, Inc. v. Goodyear Tire & Rubber Co.,
Here, defendants argue that because plaintiffs moved to strike their experts for failure fully to disclose testimonial history based on Carlson, Svendsen, and Trattler I, plaintiffs cannot now change their position and rely on Trattler II to argue that the trial court erred by striking their own expert for the same reasons. We are not persuaded.
*230
For judicial estoppel to apply, five cireumstances must be present, including "the inconsistency must be part of an intentional effort to mislead the court." American Guarantee and Liability Ins. Company v. King,
Under the invited error doctrine, a party is prevented frоm "inducing an inappropriate or erroneous [ruling] and then later seeking to profit from that error." Horton v. Suthers,
Defendants cite no case in Colorado applying these doctrines to preclude an appellant from relying on a post-trial supreme court opinion despite having argued otherwise below based on cases overruled by that opinion. We reject such a limitation because it would frustrate the general application of judicial decisions retroactively. Further, "(al contrary rule wоuld induce parties to drown the trial judge with reservations." United States v. Charley,
We are not persuaded otherwise by defendants' reliance on Maiz v. Virani,
Here, in contrast, the supreme court had denied certiorari in Svendsen and granted certiorari on another ground in Carison, which it affirmed. We discern nothing in our supreme court's prior C.R.C.P. 37(c)(1) cases that predicted Trattler II. Defendants cite no trend in federal cases interpreting the comparable federal rule that foretold Trattler II. See Hensley v. CSX Transportation, Inc., No.
Accordingly, we conclude that neither invited error nor judicial estoppel precludes plaintiffs from relying on Trattier II.
IV. Trattler II
Finally, we agree with plaintiffs that under Traitler II the trial court erred by striking one of their expert witnesses for failure fully to disclose tеstimonial history. Plaintiffs concede, and we agree, that for the same reason the trial court erred by striking two of defendants' experts.
The Trottler II majority held that C.R.C.P. 87(c)(1) "only requires the preclusion of undisclosed evidence."
Here, concerning two of defendants' experts the trial court explained:
I think the Svendsen case is rather inflexible. And it reaffirms the concept that the failure to disclose is not harmless almost as a matter of law.
[[Image here]]
So it seems to me the disclosures were not made and were not made prior to the deposition; that Rule 37 compels that the witness not be allowed to testify.
(Emphasis added.) Then as to plaintiffs' expert, the court said:
[The expert] has testified that there are probably some trials missing and the rule is very clear that you have to list both deposition and trial testimony.
[[Image here]]
So for those same reasons, I'll exclude [the expert's] testimony.
Observing that a C.R.C.P. 37 sanction "is automatic and self-executing," the court did not consider any of the alternative sanctions in C.R.C.P. 87(c)(1).
Because this analysis was rejected in Trattler II, we conclude that the trial court erred by striking these three expert witnesses. We are not persuaded otherwise by defendants' argument that the trial court acted within its discretion because C.R.C.P. 87(b)(2)(B) permits preclusion of evidence for nondisclosure.
C.RCP. 87(c)(1) provides that a court "may impose other appropriate sanctions, which ... may include any of the actions authorized pursuant to subsections (b)(2)(A), (b)(2)(B), and (b)@(C) of this Rule." C.R.C.P. 87(b)(2)(B) authorizes an order "refusing to allow the disobedient party to support or oppose designated claims or defenses, or prohibiting him from introducing designated matters in evidence."
Here, as in Trattler II, the trial court did not consider C.R.C.P. 37(b)(2)(B) because it believed C.R.C.P. 37(c)(1) required preclusion of the experts. However, even if the trial court had done so, as explained in Trait-ler II, "(tlo properly exercise its discretion to impose an appropriate sanction, the trial court should first look to the nature and severity of the violation and then to the alternative sanctions specified in the rule."
Thus, on remand the trial court "may consider rescheduling depositions or trial, payment of attorney fees and costs, contempt proceedings against the experts, admitting evidence of the noncompliance, instructing the jury that noncompliance may reflect on the credibility of the witness, or any other sanction directly commensurate with the prejudice caused." Trattler II, 182 P.38d at 683. But we conclude that preclusion of expert testimony for incomplete disclosure of testimonial history, absent bad faith, would be disproportionate. Id. at 688..
Accordingly, we further conclude that the trial court erred by striking one of plaintiffs' experts and two of defendants' experts for failure to provide complete testimonial histories.
Having so concluded, we need not address plaintiffs' alternate argument that their failure fully to disclose the expert's testimonial history was substantially justified or harmless. See Traitler II,
V. Cross-Appeal
As noted above, we agree with defendants that their two experts who were stricken for failure fully to disclose testimonial histories should be allowed to testify on retrial. However, as to defendants' third expert, who was stricken for other reasons, Trattler II does not apply.
*232 We decline to address defendants' contention on cross-appeal that the trial court erred by striking this expert because he "was not endorsed or made available" before the deadline for expert depositions.
According to defendants' Statement of Relevant Facts:
Plaintiffs argued that [the expert] should be precluded from testifying because his deposition was not taken before ... the court imposed deadline. [The expert's] father-in-law was terminally ill with cancer and [the expert's] wife had to travel to visit her father while [the expert] took care of their two small children.
However, defendants make no argument and cite no authority as to why the trial court's ruling striking this witness was an abuse of discretion. See People in Interest of D.B.-J.,
Reversal and remand for a new trial does not automaticаlly reopen discovery. See Cleveland By and Through Cleveland v. Piper Aircraft Corp.,
However, our holding does not preclude defendants from moving the trial court for leave to reopen discovery to afford plaintiffs an opportunity to depose their third expert, and on the basis of such a deposition, if it is allowed, to request that the court reconsider its ruling striking this expert.
VL Cost Award
Given our conclusion that the underlying judgment must be reversed, the award of costs against plaintiffs is vacated. See Nichols v. Burlington Northern & Santa Fe Ry.,
The judgment is reversed and the case is remanded with directions.
