Mosquito fogging operations in parts of Jolly Harbour have been temporarily suspended following a High Court hearing on Tuesday, as a legal dispute between a homeowner and a developer continues to unfold.

The matter, involving freeholder Cyprian Kowalczyk and Caribbean Developments (Antigua) Limited (CDAL), came before the High Court of Justice on May 5, 2026, before Madam Justice Birnie Stephenson. Following the hearing, mosquito fogging in the area around Kowalczyk’s home has been temporarily halted pending further order of the court.

The application was filed on April 14, 2026, and first set down for April 28, a notably fast turnaround for a contested civil matter in Antigua. Kowalczyk said the hearing was later rescheduled to May 5 at approximately one hour’s notice.

Procedural concerns raised

Kowalczyk, who is representing himself in the proceedings, raised a number of procedural concerns. He stated that while he was permitted to appear and address the bench, he was not allowed to sit at counsel’s table. Instead, he had to use spare chairs in the well of the court to hold his materials, laptop, and the courtroom microphone used to address the judge.

He argued that this arrangement is difficult to reconcile with Rule 1.1 of the Eastern Caribbean Supreme Court Civil Procedure Rules 2023, which requires that cases be dealt with justly and that parties be placed, as far as possible, on equal footing. He said the situation, combined with the challenges of self-representation, placed him at a structural disadvantage against a defendant with full legal representation.

Kowalczyk also stated that several fellow Jolly Harbour freeholders who support his case and attended the hearing were not admitted to the courtroom. He said the judge indicated that the matter was being heard in chambers. While Section 15(9) of the Constitution of Antigua and Barbuda provides that proceedings should ordinarily be held in public, Section 15(10) allows certain interlocutory matters to be heard in chambers.

Kowalczyk questioned whether the chambers designation alone justified their exclusion, particularly in a case that directly affects other freeholders exposed to the same fogging programme.

Evidence and materials questioned

During the hearing, concerns were reportedly raised about both the volume of materials submitted and the type of evidence presented. Kowalczyk stated that he filed approximately a dozen peer-reviewed scientific studies and a similar number of legal authorities, many of which were between 20 and 30 pages in length.

He described this as a challenge faced by self-represented litigants, noting that submitting too little material could result in criticism that a case has not been properly made out, while submitting extensive documentation may draw concerns about volume.

Among the evidence presented was a recent photograph exhibited to an affidavit sworn by his wife, showing swelling around their eleven-year-old daughter’s eyes on April 28, 2026, taken about a day after a fogging event. Kowalczyk said the court questioned why no medical expert report had been filed and raised the possibility that the image could have been generated by artificial intelligence, despite his wife swearing under oath that she took the photograph.

He maintained that expert medical reports are not required at the interim stage of proceedings and noted that an official audio recording of the hearing exists as the record of what transpired.

Substantive legal arguments

In his submissions, Kowalczyk framed the central issue as whether one freeholder may release a chemical mist from its land that drifts onto another freeholder’s property, interfering with that owner’s use and enjoyment of their home and their natural right of way to the public road. He argued that the common law does not permit such interference.

He also referred the court to a decision from a United States court in which similar relief, including a buffer zone to prevent a truck-mounted ultra-low-volume mosquito fogger from operating near a private home, was granted on comparable facts. He argued that the relief he is seeking is neither new nor unprecedented.

Addressing concerns raised from the bench about mosquitoes as a public nuisance and disease vector, Kowalczyk acknowledged having contracted dengue fever himself. However, he argued that scientific studies submitted to the court indicate that high-frequency adulticide fogging does not effectively reduce mosquito populations and may worsen the problem by killing natural predators and promoting resistance.

He pointed to alternative mosquito control methods, including larviciding with Bacillus thuringiensis israelensis (Bti), source reduction, and biological control, noting that his application does not seek to restrain these approaches.

Health and safety concerns

Kowalczyk said his primary concern is the long-term health impact on his family, particularly his children. He noted that the manufacturer’s label for the chemical product Zenivex E20 limits applications to no more than 25 per site per year.

According to the materials he submitted, more than 36 spray events had already taken place in the area by the time of the hearing, exceeding the recommended annual limit with several months remaining in the year. He emphasized that this limit is based on a safety threshold derived from risk assessments by the United States Environmental Protection Agency (EPA), designed to protect vulnerable populations such as toddlers.

He also noted that fogging often occurs in areas where residents, including mothers with young children, are present.

Property rights and legal authority

Kowalczyk further argued that there is no contract, statute, or regulatory licence permitting CDAL to release chemical aerosol onto his registered freehold land. He challenged the characterization of Jolly Harbour as a managed community, describing it instead as a “scheme of development” in which individual buyers hold independent registered titles.

He added that while CDAL continues to demand payments related to his property, those matters are the subject of separate legal proceedings and are not part of the current application.

Pre-action correspondence

The court also examined whether efforts had been made to resolve the matter prior to litigation. Kowalczyk stated that he presented correspondence showing that CDAL’s attorneys have not responded to him since May 2025, despite written objections sent in January, March, and April 2026 requesting that fogging in the area around his home be stopped.

Next hearing date

Following submissions, the court ordered a temporary halt to mosquito fogging in the vicinity of Kowalczyk’s property. The matter is scheduled to return to court on June 4, 2026, when the terms and duration of any continuing relief are expected to be considered.

The proceedings are ongoing.
