Successive RSA 173-B Protection Orders: New Post-Adjudication Abuse Defeats Claim Preclusion and Opens the Door to Prior Acts as Pattern Evidence

Introduction

In J.M. v. D.E. (Supreme Court of New Hampshire, May 28, 2026), the defendant, D.E., appealed domestic-violence orders issued by the Circuit Court granting a final order of protection to the plaintiff, J.M., under RSA chapter 173-B, and denying reconsideration.

The appeal presented a focused procedural question with substantial practical consequences in domestic-violence litigation: whether a second protective-order petition must be dismissed under res judicata (claim preclusion) or collateral estoppel (issue preclusion) when it overlaps factually with an earlier petition that was dismissed, but also alleges a new development occurring after the first adjudication.

The case arose from two petitions: (1) a 2024 petition alleging physical assault, threats, and property destruction that was dismissed after hearing for failure to prove “abuse” as defined in RSA 173-B; and (2) a 2025 petition supported by videos and testimony, including evidence of threats with a firearm and renewed fear after J.M. reported the video to police and believed D.E. began driving by her residence.

Summary of the Opinion

The Supreme Court affirmed the final order of protection. It held that neither res judicata nor collateral estoppel barred the second petition because the plaintiff alleged and proved an act of abuse occurring after the first petition was adjudicated: the defendant’s prior conditional threat (“if you go to the police, I will kill you”) became a present threat once she reported him, and she then experienced subsequent conduct (suspected drive-bys) that heightened her fear.

Because a post-adjudication act of abuse was established, the Court further held that RSA 173-B:1, I authorized the trial court to consider all other acts of abuse “regardless of their proximity in time” to determine whether an ongoing pattern created a credible present threat. The Court therefore found no error in the trial court’s reliance on conduct that had been previously litigated.

Notably, the Court declined to decide the amici’s broader argument that preclusion doctrines have limited or no application in RSA 173-B cases, resolving the appeal on narrower grounds: new post-adjudication abuse defeats preclusion in any event.

Analysis

Precedents Cited

  • Walker v. Day, 173 N.H. 211 (2020)
    Cited for two core propositions: (1) the applicability of res judicata is a question of law reviewed de novo; and (2) the definition of res judicata as barring relitigation of matters actually decided and matters that could have been litigated between the same parties for the same cause of action. The Court relied on Walker to frame the standard of review and the doctrinal test.
  • Barry v. N.H. Dep't of Health and Human Servs., 170 N.H. 364 (2017)
    Cited alongside Walker for the proposition that preclusion is reviewed de novo. Its function is methodological: it reinforces that the Supreme Court independently assesses whether preclusion applies to successive proceedings.
  • Gray v. Kelly, 161 N.H. 160 (2010)
    Performed two important roles. First, it places the burden on the party asserting preclusion. Second, it supplies the Court’s articulation of “cause of action” (as the right to recover regardless of theory) and the key limitation (also emphasized in the order’s footnote): res judicata bars only claims that could have been litigated and that arose from a transaction or occurrence actually litigated previously; it does not bar claims arising from an occurrence not litigated, even if known at the time. This framework supported the Court’s conclusion that the post-adjudication change in threat status was not precluded.
  • Merriam Farm, Inc. v. Town of Surry, 168 N.H. 197 (2015)
    Cited for the “same cause of action” inquiry: whether the claims arise out of the same factual transaction or occurrence. This “transactional” approach is central to the Court’s rejection of preclusion where the second petition depended on a new post-adjudication occurrence.
  • Cook v. Sullivan, 149 N.H. 774 (2003)
    Cited for the definition of collateral estoppel as narrower than res judicata, barring relitigation of issues actually litigated and determined. The Court used it to explain why, once a post-adjudication act is shown, the second petition cannot be dismissed merely because some issues overlap.
  • L.C. v. W.C., 174 N.H. 355 (2021)
    Provided the substantive RSA 173-B standard: a petitioner must prove “abuse” by a preponderance, requiring (1) an enumerated act and (2) that the conduct constitutes a credible present threat. The Court used L.C. to organize the statutory elements and to justify the trial court’s focus on present threat.
  • Beckles v. Madden, 160 N.H. 118 (2010)
    Cited for the principle that uncertainties or indecisive wording in testimony do not automatically render evidence insufficient; credibility and weight are for the trial court. This supported affirmance despite the plaintiff acknowledging she was “speculating” about the drive-bys.
  • In the Matter of Kurowski & Kurowski, 161 N.H. 578 (2011)
    Reinforced that conflicts in testimony and credibility determinations belong to the trial court, insulating the factual basis for “present credible threat” from appellate reweighing.

Legal Reasoning

The Court’s reasoning proceeds in three steps: (1) define the preclusion doctrines and the statutory elements; (2) identify a post-adjudication act that defeats preclusion; and (3) apply RSA 173-B’s pattern-evidence rule once a qualifying post-adjudication act exists.

  1. Preclusion is legal, but its application depends on the factual “transaction/occurrence.”
    Applying Walker v. Day, Gray v. Kelly, and Merriam Farm, Inc. v. Town of Surry, the Court treated res judicata as turning on whether the second petition was the same cause of action—i.e., the same transaction or occurrence—and whether the new matter could have been litigated earlier. Collateral estoppel, under Cook v. Sullivan, would bar only issues actually litigated and determined.
  2. RSA 173-B requires a “credible present threat,” which can evolve after the first case ends.
    Using L.C. v. W.C. and RSA 173-B:1, I, the Court emphasized that protective orders are not merely backward-looking adjudications of past conduct. They are forward-looking: the court must find an enumerated act and that it creates a present credible threat. This statutory focus matters because changes after an earlier dismissal can convert prior conduct into a current threat assessment.
  3. The key “new act” was the post-adjudication shift from conditional to present threat.
    The Court identified a legally meaningful post-adjudication development: J.M. reported the firearm-threat video to police after the first petition’s dismissal, and D.E.’s prior warning that he would kill her if she reported him ceased to be hypothetical once she did so. The Court described this as a change from a conditional threat to a present threat, which “could not have been litigated in the earlier action.” That finding alone prevented dismissal under both res judicata and collateral estoppel, because the second petition was not confined to an already-adjudicated transaction/issue.
  4. Once a post-adjudication act is shown, RSA 173-B authorizes consideration of prior acts irrespective of time.
    The Court treated as undisputed that if a new act occurs after the earlier adjudication, RSA 173-B:1, I permits the court to consider “all previous alleged acts” to determine whether there is an ongoing pattern causing fear for safety or well-being. This statutory authorization justified the trial court’s use of videos and allegations that overlapped with the first petition.
  5. Appellate deference to factual findings protected the “present threat” determination.
    Although the plaintiff conceded on cross-examination she was “speculating” about seeing D.E. drive by, the Court invoked Beckles v. Madden and In the Matter of Kurowski & Kurowski to hold that uncertainty and credibility are for the trial court. Combined with the newly activated threat (reporting to police), the record supported the trial court’s “credible present threat” finding.

Impact

The decision establishes a practical, litigation-shaping rule for RSA 173-B proceedings: a second protective-order petition is not barred by res judicata or collateral estoppel when the petitioner shows a post-adjudication act of abuse or threat development, even if the petition also relies on previously litigated conduct.

Likely consequences include:

  • Lower dismissal rates for “repeat” petitions where circumstances evolve. Petitioners who previously failed to meet their burden are not categorically foreclosed from future protection when new facts arise.
  • Greater evidentiary relevance of prior incidents once a new act occurs. The opinion confirms robust use of “pattern” evidence under RSA 173-B:1, I after a new qualifying event—supporting protective orders based on cumulative risk.
  • Strategic focus on post-adjudication developments. Respondents asserting preclusion must confront whether the petitioner can point to any new act or threat change after the earlier judgment; if so, preclusion arguments weaken substantially.
  • A narrowed route to preclusion without deciding its outer limits in RSA 173-B cases. Because the Court explicitly avoided ruling on amici’s broad theory that preclusion doctrines are categorically limited in domestic-violence cases, future litigation may still test whether and when res judicata/collateral estoppel can apply absent any post-adjudication conduct.

Complex Concepts Simplified

Res judicata (claim preclusion)
A rule that generally prevents the same parties from re-litigating the same “cause of action” after a final judgment. In New Hampshire, courts often ask whether the later claim arises from the same “transaction or occurrence.”
Collateral estoppel (issue preclusion)
A narrower rule that prevents re-litigating a specific issue of fact or law that was actually litigated and decided in a prior case.
“Credible present threat” (RSA 173-B)
Not just whether something bad happened before, but whether the defendant’s conduct—viewed in context—creates a current, believable risk to the petitioner’s safety. This can change over time as events unfold (for example, when a conditional threat becomes active).
Conditional threat vs. present threat
A conditional threat depends on a future trigger (“If you do X, I’ll harm you”). A present threat exists once the condition is met or circumstances otherwise make the risk current. Here, the Court treated reporting to police as converting the defendant’s earlier conditional threat into a present safety risk.
Pattern evidence under RSA 173-B:1, I
The statute allows the court to consider older incidents—even long before the filing—when they combine with more recent conduct to show an ongoing pattern that causes fear.

Conclusion

J.M. v. D.E. clarifies how preclusion doctrines interact with New Hampshire’s domestic-violence protective-order statute. Where a petitioner demonstrates a post-adjudication act of abuse or a post-adjudication change that creates a present credible threat, res judicata and collateral estoppel do not bar a new RSA 173-B petition, and the trial court may then consider prior acts—regardless of their age—as pattern evidence under RSA 173-B:1, I.

The opinion strengthens RSA 173-B’s protective, forward-looking function: it allows courts to respond to evolving risk, rather than freezing the parties’ rights at the moment of a prior dismissal.
