It is claimed that the hierarchy of legal effect is determined by conditional relationship, and the fact that the Hong Kong National Security Law is formulated in accordance with the Hong Kong Basic Law would determine that the legal effect of the former is inferior to that of the latterHowever, the hierarchy of legal effect is different from its validityA certain conditional relationship can only determine the validity and cannot determine the hierarchy of legal effectThe terminology“norm hierarchy”includes two different thingsThe first is the norm rank determined by a certain conditional relationship, which is the hierarchical relationship between two normsThe second is the hierarchy of legal effect as a kind of legal force derogation relationship, which is the hierarchical relationship between two types of norms, essentially a kind of conflict ruleThe setting of the hierarchy of legal effect is chosen by legislators after consideration of various factors according to the countrys political system and historical traditions, and is not restricted by conditional relationsAlthough a conditional relationship does not determine the hierarchy of legal effect, it can affect the application of the rules of the hierarchy of legal effectBased on the conditional relationship, the lowerlevel norms can inherit the priority application status of the higherlevel norms on which they are based in the higherlevel law, so that lowerlevel norms have priority over other higherlevel norms.
