Right to free gathering Act of Supplements and Alterations to the Law on Public Gathering stipulated that no public gatherings could be held within 100 meters of buildings in which the Croatian Parliament, President of Republic, the Croatian Government or the Constitutional Court are located or are in session (the Parliament, Government and the Court are all located at
St. Mark's Square) On 6 July 2011, Constitutional Court ruled that this law, which restricts a Constitutional liberty – the right to free gathering, was not passed by the majority necessary to override the Constitution on that matter. The Court's decision was that the law shall be put out of effect at a date specified by the Court. The Court also provided Parliament with the necessary number of representatives which must confirm the Act to make it legitimate.
2013 referendum and same-sex unions On 14 November 2013, Constitutional Court in a 13–0 statement sent to the State Election Commission stated that there is no constitutional obstacle to hold a
2013 referendum on defining marriage as a union between men and a woman, in the same time pointing out that the referendum revealed numerous problems in the
Referendum law and opened a number of legal questions that required answers. Nevertheless, the Court stressed that decision on the referendum was passed by a majority of 104 MPs and that since it was made with more votes than the majority needed to even change the Constitution itself, the referendum should be held. In addition, the Court asked Croatian Parliament to "provide a stable regulatory framework of the referendum process that meets the standards of a democratic society as soon as possible". The Court also decided that "any amendments to the Constitution which would define marriage as being union between a man and a woman should not have any effect on the further development of the legal framework of the institution of same-sex unions in accordance with the constitutional requirement that everyone in Croatia has the right to be respected and right of legal protection of their personal and family life and human dignity". The Court pointed out that it had never received any request or proposal to review the constitutionality of the provisions of the
Family Law that regulated marriage as a union between a man and woman, or provisions of the
Law on Same-Sex Unions. The Court therefore considered that the referendum on the definition of marriage is not a referendum on the right to respect for family life, because it is constitutionally guaranteed to all persons, regardless of sex and gender, and is under the direct protection of both, the Constitutional Court itself and the European Court of Human Rights. In conclusion, the Court warned that "incorporation of legal institutes in the constitution shouldn't become a systemic phenomenon" and that exceptional individual cases must be justified by being connected, for example, with deep-rooted social and cultural characteristics of the society.
Abortion On 21 February 2017, Constitutional Court announced that it held in a 12–1 decision that it won't accept constitutional complaints submitted by the conservative NGO's
Croatian Movement for Life and Family (in 1991) and
In the Name of the Family (in 2010) to review conformity of the 1978
Law on Health Measures for the Realization of the Right to Freely Decide on Childbirth with the Constitution. According to Court's decision, it recognized constitutionally guaranteed value of unborn being and not its right to life but rather public interest of the state to protect it. The Court considered that abortion as a constitutional or a human right doesn't exist. According to the Court, the right of privacy of women, which includes the right of freedom, dignity and the protection of family and private life, exists, which gives woman autonomy to a certain period (in Croatia 10 weeks after conception) during which woman can freely decide whether she wants to give birth or not, but after that period of time birth becomes public interest which protects the right to life of the unborn. With this decision, the Court obligated the
Croatian Parliament to enact new law within two years and has warned it to take into account the fact that existing law contains certain institutions that no longer exist in the Croatian constitutional order (since the Law is based on the
1974 Yugoslav Constitution) and that the adoption of the
1990 Croatian Constitution built a brand new legal and institutional framework of health, social, scientific and educational system. New law should determine the educational and preventive measures "so that abortion should be an exception". In sole
dissenting opinion, Judge Miroslav Šumanović, among other things, stated that the 1978 Law should be formally and substantially aligned with the Constitution, abolished with a deferment effect, that the new one should be enacted, and that it is the duty of the state to protect the right to live of the unborn being.
Oversight of Criminal Law Amendments (2025–2026) Following the 2024 introduction of the "Unauthorized Disclosure of Investigative Content" (Article 307a of the Criminal Code), the Constitutional Court began reviewing petitions regarding its impact on freedom of expression. In early 2026, the Court stated that any application of the law must respect the European Court of Human Rights standards on "public interest" and the protection of journalists. ==Composition==
