The media are free to take into account information that is transmitted through leaks, under certain conditions:
The source of the leak must be known to the media to which it is leaked.
The theme of the leak must have public relevance.
There should be good reasons for publishing the information without waiting. Achieving a competitive advantage is not reason enough.
It should be established that the subject or the document is classified as secret or confidential, definitively or for the long-term, and is not simply under embargo for a few hours or days.
Leaks should be communicated knowingly and willingly by the source and should not be obtained by dishonest methods (bribery, blackmail, bugging, housebreaking or theft).
The publication should not violate rights and secrets self-evidently deserving of protection.
