The Hawaii Intermediate Court of Appeals has upheld a harassment injunction against Gio Mantelli, a resident accused of disturbing his neighbor, Jessica Reimann. The court's decision, issued on June 16, 2026, confirms the lower court's ruling that Mantelli's actions constituted harassment under Hawaii law. This ruling is significant as it highlights the legal standards for harassment and the rights of property owners to seek protection from disruptive neighbors.
The dispute began when Reimann filed a petition for a temporary restraining order against Mantelli and his co-respondent, Kristen Santos, in January 2023. Reimann alleged that Mantelli and Santos were operating a food truck business without the necessary permits and that their activities were causing significant disruptions to her health and privacy. The situation escalated when Reimann claimed that Mantelli made threats against her family, stating he would use all his resources to make their lives miserable. The case eventually reached the Intermediate Court of Appeals after Mantelli challenged the lower court's decision.
The Hawaii Intermediate Court of Appeals, consisting of Chief Judge Karen T. Nakasone and Associate Judges Katherine G. Leonard and Sonja M.P. McCullen, reviewed the case and affirmed the district court's ruling. The court found that the district court had sufficient evidence to grant the harassment injunction, which prohibits Mantelli from contacting or threatening Reimann and imposes specific restrictions on his activities near their shared property line.
The court's ruling highlighted two key points raised by Mantelli in his appeal. First, he argued that the district court failed to apply the correct legal standards for issuing a harassment injunction. Specifically, he contended that the court did not adequately consider whether his actions served a legitimate purpose or whether they would cause a reasonable person to suffer emotional distress. The court, however, found that the evidence presented clearly demonstrated that Mantelli's conduct was intended to alarm and disturb Reimann and her family.
In its opinion, the court stated, "The findings reflect that Mantelli's and Santos's conduct at the shared property line was intended to seriously alarm and continually disturb Reimann and her family." The court also noted that Mantelli's threats and actions were sufficiently alarming to justify the issuance of the injunction.
Second, Mantelli argued that the injunction was overly broad and imposed unreasonable restrictions on his lawful use of his property. He claimed that the requirement to relocate any structures within 100 yards of the shared property line was excessive. However, the court determined that the restrictions were necessary to address the specific conduct that constituted harassment and were supported by substantial evidence. The court emphasized that Mantelli had ample space on his 14-acre property to relocate activities that were causing distress to Reimann.
The court's decision has implications for future cases involving neighbor disputes and harassment claims. It reinforces the importance of protecting individuals from harassment while balancing property rights. The ruling also clarifies the legal standards that courts must consider when determining whether to grant a harassment injunction.
Moving forward, this case sets a precedent for how courts in Hawaii may handle similar disputes. It highlights the need for individuals to be aware of their rights and the legal avenues available to them if they feel threatened or harassed by neighbors. The decision also emphasizes the responsibility of property owners to ensure that their activities do not infringe upon the rights and well-being of others.
As for Mantelli, he has the option to appeal the decision to a higher court, although details regarding any potential appeal were not available in the court filing. The outcome of this case may influence how future harassment injunctions are issued and enforced in Hawaii.
