Subjecting public administration to the rule of law requires the existence of the system of legal guarantees. Basic importance must be attributed here to prevention guarantees among which one should distinguish legal institutions of different character, organizational, substantive and procedural character. Repressive guarantees, that is deducing legal consequences from breaching the law by public administration of the rule of law must consider protection of rights acquired by individual. It is not permissible to shift legal consequences of breaching the constitutional rule of legality onto individual. Individual should possess - in trust to public authorities - right to expect that entire activity of aforementioned authorities is the consequence of legality and not lawlessness. Establishing the system of guarantees of subjecting public administration to the rule law should be based on institutions which should eliminate its infringements. Of course, system of legal guarantees of the rule of law cannot be closed only to the preventive guarantees. Such system doesn’t create a ‘perfect’ model of public administration for which unfamiliar is contravention of the rule of law. Nonetheless, repressive guarantees should complement the system of preventive guarantees. Disposition of the right to defense by individual should be one of the element of aforementioned completeness.
