SYNTAX: filter which requires an (overtly realized) NP argument to be case marked, or be associated with a case position. EXAMPLE: this filter rules out (i). No case is assigned to the subject position of the complement of seems; only by moving to the subject position of the matrix clause can John satisfy the case filter: it is assigned case there.
(i) a * it seems [ John to be angry ] b John seems [ ti to be angry ]More recently, the case filter has been reduced to the visibility condition. See also chain condition.
