This paper proposes a new case-based approach to some facts observed in complement clauses in Korean. Its core lies in the following hierarchy: lexical/oblique case >> verbal case >> default case. This paper shows that among others, case conversion on the embedded subject in the ECM environment, i.e., from nominative to accusative, follows from the particular conception of nominative as the absence of case valuation advanced by Preminger and his co-workers (2014, 2015) according to which case is not contingent on agreement. This approach also deals with contrasts in ellipsis of complement clauses. In addition, this paper points out that a labeling system proposed by Cecchetto and Donati (2010) does not extend to Korean, and claimed that a moving element does not reproject a label.
