In the modern state based on the rule of law, the right to a reasoned decision is one the most important procedural safeguards as well as a fundamental element of procedural legality the aim of which is the protection of the parties’ rights. Precise, comprehensive and substantial reasoning enables the party to get acquainted with the reasons for the decision and contributes to a greater acceptance of the decision. Moreover, a reasoned decision is a prerequisite for an effective remedy in which the legality of the decision is being reviewed and which indirectly prevents arbitrary decisions of the public authorities. A decision is a unilateral and authoritative measure, issued by competent administrative or other government authority, local authority or bearer of public authority as a superior body in the context of exercising of public authority. Therefore, the procedural legality of individual acts is particularly important.
