The copyright to this work was owned by the federal authorities of the former Socialist Federal Republic of Yugoslavia, whose assets are now held jointly by its successor states according to the Agreement on succession issues of 2004 [1]. The Yugoslav successor states have variously enacted legislation that places certain official state documents such as law texts into the public domain.

See e.g. Art. 8.2.1 of the copyright law of Croatia [2]: "official texts in the domain of legislation, administration, judiciary (acts, regulations, decisions, reports, minutes, judgments, standards, and the like) and other official works and their collections, which are published for the purpose of officially informing the public".

This template must not be used on its own. To establish PD status it must be used only with an appropriate license template such as {{PD-Croatia-exempt}}. You must make sure the file content has been declared as public domain by the laws of the relevant successor state.

According to the Slovene Copyright Act, this image is in the public domain.
