The Republic of Slovenia's constitution, adopted in December 1991, contains no provisions on political parties or their financing. The Political Parties Act contains detailed rules regarding these sources of financing, mostly those from private donations, budgetary allocations and companies owned by the parties. Slovenian law prohibits political parties from receiving funds from abroad. However, the law is very vague and raises numerous questions, such as the right of parties to collect regular membership fees from members residing abroad. State budget allocations are an important source of funding for Slovenian political parties. The National Television Act prescribes that Slovenian national television has to give a certain part of its program time to the political parties for free so that they can present their platforms and candidates to voters. The financing of Slovenian parties is generally regulated by party constitutions. However, detailed provisions on financing are included in other party documents, usually in some kind of party regulations dealing with party financing.
