The Services Directive obliges Member States to cooperate with each other and give mutual assistance in the supervision of service providers. Competent authorities of different Member States have to exchange information with each other and carry out checks, inspections and investigations upon request. They also have to send an alert to other Member States in cases relating to a service activity that could cause serious damage to the health or safety of persons or to the environment. For this purpose the Commission in cooperation with Member States established an electronic system for the exchange of information (IMI).
