This may be termed ＂norms of legality＂ in relation to the effect of juristic acts （Rechtsgeschaft）.

In determining whether legal acts that contravene public law are valid, the objectives of the related public laws must be examined and the principle of proportionality applied to limit the interpretation of the objectives of the public law in question, in order to further distinguish obligations in public law from those in private law.
