A permissioned blockchain is used in a lawful interception, LI, context. Participants include a law enforcement agency, LEA, function, a LI mediation and delivery function, MF/DF, and an intercepting network function. A smart contract registered in the blockchain includes conditions associated with intercept related information, IRI, and/or communication content, CC, transactions. Registration is made in the blockchain of IRI and/or CC transactions performed by the participants during LI of a communication between two entities in a telecommunication network. The registered IRI and/or CC transactions are propagated among the participants and the smart contract is executed to verify whether or not the registered IRI and/or CC transactions are compliant with the smart contract. The participants are then informed about whether or not the registered IRI and/or CC transactions are compliant with the smart contract.
