The law of sustainable development shall be able to meet the challanges of clarity, enforceability, thus one should try to be more specific then it is acceptabel in the wider the political context. Several international documents, conventions, even EU legislation wants to come closer to the problem. If we wish to translate the content into the legal language, then there are some elements of such a legal system, which we would like to underline: inter-generational equity and right to environment, public participation, cooperation, integration, precaution and subsidiarity.

The concept of the responsibility to protect has emerged in the practice of the United Nations in the past years, inducing much criticism in the literature.

A szlovákiai ügyészség alkotmányos jogállása és törvényi szabályozása hosszú ideje vita tárgya. Az érdeklődés egyik oka kétségkívül az, hogy az ügyészség tevékenységének, hatáskörének szabályozása a szakmai és a laikus nyilvánosságot is érinti.
