You can submit an application to the Constitutional Court if you believe that your human rights have been violated by a legal provision or an individual decisions taken by state bodies, bodies of local and regional self-government and legal persons vested with public authority.
However, there are some conditions which you have to take into account before you can submit a complaint:
The Constitutional Court will only accept and examine an application about a violation of your human rights.
example The Court will not accept your application if you complain about the inefficiency of an organizational structure of the government.
You cannot complain about the violation of another person’s human rights, unless you have a right to represent that person.
example You can complain about the violation of another person’s human rights if you have been granted a power of attorney allowing you to do that or if you have a legal right to represent that person (for example you are a parent of a minor or you are a legal guardian).
The Constitutional Court cannot investigate a potential violation of your rights if you have not first tried to resolve the problem using all the usual complaint mechanisms that are available under Croatian law.
example If you believe that certain legal provision does not allow you access to a regular court, you should try to apply to that court first and ask to accept your claim. If that court refuses to accept your claim, you must appeal that decision to all available instances of appeal. Only then you can complain to the Constitutional Court.
The Constitutional Court can exceptionally initiate proceedings in response to a constitutional complaint even before all legal remedies have been exhausted.
These proceeding are initiated in cases when the competent court of justice did not decide within a reasonable time about the rights and obligations of the party, or about the suspicion or accusation for a criminal offence, or in cases when the disputed individual act grossly violates constitutional rights and it is completely clear that grave and irreparable consequences may arise for the applicant if Constitutional Court proceedings are not initiated.
