The Davao Region of the Philippines has a well-developed banana industry.  A 2006 study commissioned by the Department of Health found that aerial spraying of pesticides was having negative effects on the health of residents of Kamukhaan (Camocaan), Davao del Sur province, and it recommended the aerial spraying be banned.  In 2007, Davao City passed an ordinance banning aerial spraying of pesticides, and encouraged ground spraying instead.  Banana companies (Pilipino Banana Growers and Exporters Association (PBGEA), Davao Fruits and Lapanday Agricultural Development) questioned the legality of the ban in court, and filed a lawsuit against the City of Davao seeking to strike down the ordinance as unconstitutional.  The Regional Trial Court allowed villagers affected by the pesticide spraying to intervene in support of the City and its ordinance, and the villagers have since become a party to the case.

The Regional Trial Court found that the ordinance was constitutional, but this decision was reversed by the Court of Appeals in 2009, despite a filing by the Office of the Solicitor General stating that the ordinance is valid and constitutional.  Davao City and the villagers brought this decision to the Supreme Court for review.  The Court of Appeals has granted an injunction on the implementation of the subject ordinance, which means that banana companies are able to continue using the aerial spraying method while the Supreme Court reviews the case.

In August 2016, the Supreme Court ruled that the Davao City ordinance banning aerial spraying of pesticides was unconstitutional.
