In most cases, checking of signatures is centralised and carried out by the central electoral commission (Albania, Latvia, Lithuania, Russia – where at least 40% of the required number of signatures are checked) or an equivalent body (Hungary, Malta).  In Italy, a special office of the Court of Cassation is responsible for this task; in Switzerland, it is the Federal Chancellery; in “the former Yugoslav Republic of Macedonia”, the department of state administration in the Ministry of Justice.  In Poland, the Speaker of the Sejm checks that the required number of signatures has been collected; if this is not the case, a further two weeks are allowed; the list of signatures may be sent to the state electoral board if there is any doubt about the validity of the signatures.  In the case of any dispute, the Supreme Court takes the final decision. In Portugal, parliament may request that the competent authorities check the signatures by sampling.  In some countries, signatures may be checked at local level: in Georgia, all signatures must be confirmed by a notary or the local authority (although this does not also rule out checks at national level); in the Netherlands, signatures were checked by the town hall under the temporary law. In Croatia, the referendum committee is responsible for checking the lists of signatures.
