The decision to hold a referendum was made after more than 427,000 valid requests were received within six weeks, more than the required number of 300,000 requests.
Grunden til at der skulle afholdes en folkeafstemning var, at der var blevet indgivet over 427.000 gyldige anmodninger på bare seks måneder, hvilket er mere end kravet om 300.000 gyldige anmodninger for at få en folkeafstemning.
