The First Circuit affirmed the dismissal of a malicious prosecution claim brought by a mother who was arrested after relocating with her child to Texas without her former partner's permission. The court held that the plaintiffs failed to prove the defendants acted with malice or presented false information to secure an arrest warrant, as required to overcome the presumption of probable cause.

Marilyn Besosa-Noceda moved from Puerto Rico to Texas with her minor child to accept a job offer, without obtaining permission from the child's father, Emmanuel Santiago-Melendez. Santiago, upset by the move, filed a criminal complaint alleging that Besosa had illegally deprived him of custody. Based on Santiago's sworn statement, a Puerto Rico police officer and a prosecutor sought an arrest warrant. A municipal judge initially found no probable cause, but a superior court judge later reversed that finding at a revision hearing and issued the warrant. Besosa was arrested in Texas, extradited to Puerto Rico, and detained until she demonstrated a lack of probable cause at a preliminary hearing, which led to the dismissal of the criminal charges. Besosa then sued the officer, the prosecutor, and the prosecutor's supervisor in federal court, claiming malicious prosecution under 42 U.S.C. § 1983 and Commonwealth law. The district court granted summary judgment for the defendants, ruling that the existence of a probable cause finding by a judge barred the claim absent evidence of fraud, and that Besosa had no right to be present at the warrant hearings. Besosa appealed, arguing that the district court erred by ruling on summary judgment while a discovery dispute was pending and that the defendants had violated her rights by presenting false information.

The First Circuit affirmed the district court's grant of summary judgment, addressing the appeal on two primary grounds: procedural default regarding discovery and the substantive merits of the malicious prosecution claim. First, the court rejected Besosa's argument that the unresolved discovery dispute regarding a subpoena barred the summary judgment ruling. The court clarified that while discovery may be open, a district court is not required to wait for its resolution unless the opposing party properly invokes Federal Rule of Civil Procedure 56(d). Besosa failed to file a Rule 56(d) motion explaining why she needed more time to gather essential facts, and thus waived the argument that the discovery dispute prevented a fair adjudication. Second, the court analyzed the merits of the § 1983 malicious prosecution claim. To succeed, Besosa had to prove that the defendants caused her seizure without probable cause and that the criminal proceedings terminated in her favor. While the charges were dismissed, the court noted that a dismissal alone does not prove the absence of probable cause at the time of the arrest. Because the arrest was based on a judicial warrant, Besosa could only prevail by proving a violation of the standard set in Franks v. Delaware. This requires showing that a government official presented material information in bad faith, knowing it was false, or with reckless disregard for the truth. The court found no evidence that Officer Rivera or Prosecutor Santana failed to investigate sufficiently; the law does not require officers to exhaust every lead or investigate fully when they have no reason to doubt the veracity of the accuser. Besosa identified no 'red flags' that would have alerted the defendants to the falsity of Santiago's claims. Furthermore, the court noted that Besosa could not rely on the second Rule 6 hearing to prove falsity because the record lacked an English translation of that proceeding, and there was no evidence that the original defendants were present or responsible for any statements made by a substitute prosecutor at that hearing. Finally, the court rejected the claim that Besosa was denied a right to be present at the warrant hearings, noting that neither federal nor Commonwealth law grants an absolute right to attend such proceedings. The court concluded that without evidence of knowing falsehoods or reckless omissions, the probable cause finding by the judge was sufficient to defeat the malicious prosecution claim.

The decision reinforces the high bar for plaintiffs seeking to sue for malicious prosecution when an arrest warrant has been issued by a judge. It clarifies that the subsequent dismissal of criminal charges does not automatically establish a lack of probable cause for civil liability. Instead, plaintiffs must present specific evidence that the warrant was obtained through fraud or reckless disregard for the truth. The ruling also serves as a cautionary note for appellate litigants regarding the necessity of translating foreign-language documents and the strict procedural requirements for invoking Rule 56(d) to preserve discovery disputes. The case is remanded with instructions to affirm the district court's judgment, leaving the defendants free from liability.
