Secrecy of communication vs the Federal Law "On operational-search activity"?

Question

Telecom operators

The telecom operator receives a request from the authorities to provide data about customers accessing a certain resource on the Internet (a certain domain name) in the period of interest.
In the text of the request, there is a reference to paragraphs 1 and 2 of Article 7 of the Federal Law “on operational-search activities”. The request itself is included in the "inquiry" activity.
Question: is such a request the basis for the transfer of the requested data?

Answer 1

In the same law there is an interesting article 8 :

Conducting operational-search measures that restrict the constitutional rights of a person and a citizen to the secrecy of correspondence, telephone conversations, postal, telegraphic and other messages transmitted over electric and postal networks , as well as the right to inviolability of the home, is allowed on the basis of a court decision ...

Answer 2

Undoubtedly. Naturally, the request must be on official letterhead and with details.

Answer 3

Do not be like a known office that closed a known site on a useless piece of paper by an investigator. Only courts.

Answer 4

Just a request is not a reason, you need a corresponding court decision. You can refer to the same FZ-152
