A declarative mechanism is provided in the context of lawful interception (LI). A manifesto with information that specifies LI of a communication service or application is created and declared by a service or application provider who, is subject to LI. The declaration takes place in that the manifesto is provided from a first LI function to other LI functions in a communication system. LI data (e.g., call data record, intercept related information and call content) is subsequently generated during LI according to the manifesto by a point of interception within the service or application. The point of interception delivers the LI data to a mediation and delivery function that then forwards it to a law enforcement agency. The law enforcement agency knows how to read and manage the LI data from the manifesto.
