This paper presents an empirical generalization about scope restrictions for DPs hosting a relative clause with Antecedent Contained Deletion, indicating that scopal (non-)commutativity between the host DP and elements inside the RC constrains the scope possibilities of the host DP. The authors argue that explaining this interaction requires an amendment to the matching analysis of relative clauses such that there is at some point in the derivation not only a copy of the NP but a copy of the entire host DP including D inside the relative clause.
