“…The law is written in legal language; nevertheless, it is based on natural language, which is ‘open-textured’ (Hart et al, 1994; see also the polemic article by Schauer, 2011).

Hart and Ronald Dworkin, which has been continued to this day by their followers (Dworkin, 1963; Hart et al, 1994; Himma, 1999; Mallett, 2014; Ranchordás and De Waard, 2015; Raz, 1998; Steiner, 1976; Vila, 2013). The central issue in the discussion is not the existence of judicial discretion, but its scope.…”
