This passage can be compared to the common understanding and processing of utterances in ordinary conversation (Smolka and Pirker 2016), in which semantic content is only a vehicle for getting to the "speaker's meaning" or what is communicated-a richer content "to which meaning and obvious background assumptions have both contributed" (Soames 2008, 411; see also Butler 2016;Carston 2013;Horn 1995;Miller 1990). Legal interpretation does not differ essentially from ordinary interpretation, even though legislative speech is one-sided (there is nobody who can immediately answer back) and the basic presumption governing such texts is that the author used the language to convey ideas (Sinclair 1985, 390). However, pragmatic principles constitute a dimension of rationality which is necessary for the understanding of
