The participation totals for the National Consultation were verified by the President of the Hungarian Chamber of Civil Law Notaries on 7 December 2017.
Based on the notarised totals, 2,171,500 National Consultation questionnaires were returned by post (this number does not include responses that were submitted via the internet). The verification was performed on the basis of daily delivery documents that confirm the number of National Consultation return envelopes that were received by the Hungarian Post Office on the given day, and which were delivered to the NISZ National Info-communications Services Company. The public notary also prepared identical copies of these documents, which he attached to the notarial certificate.
A copy of the notarial certificate is available here.
