Questão jurídica principal
Whether the cantonal ordinance was applied arbitrarily by treating the complainant as an 'installer' of the gaming machines.
Decisão extraída
The application was not arbitrary; a person who materially contributes to the placement of the machines and effectively controls them may be treated as an installer.
Fundamentação extraída
The ordinance does not limit liability to the business owner. It prohibits the act of installing machines for public use, and the complainant negotiated placement, shared revenue, retained control, and handled maintenance.
