Common questions
Which countries are bound by the Budapest Convention?+
It is open to Council of Europe members and non-members that accede to it, including the United States and Japan, but a number of major states, including Russia, have not ratified it, which limits its reach as a universal cybercrime framework.
How does the Budapest Convention help with evidence stored in another country?+
It establishes mutual legal assistance procedures and expedited preservation requests, letting an investigating state ask a signatory where data is hosted to preserve or produce it, which is faster than relying solely on traditional mutual legal assistance treaties.
Does the Budapest Convention define what counts as a cyber offence uniformly across signatories?+
It sets minimum categories, such as illegal access and computer-related fraud, that each signatory must criminalise, but implementation details, penalties, and procedural rules still vary by domestic legislation, so the Convention harmonises baseline obligations rather than creating one uniform criminal code.
