In Spanish, pro triggers Condition C effects under reconstruction: it cannot c-command a lower copy of an A'-moved phrase that contains a coreferring R-expression. However, an overt subject pronoun does not. It is argued that this is not due to possible differences in the structural positions of pro and overt pronouns (cf. Cecchetto 2000 for Italian.) Developing ideas proposed in Safir 1999, and drawing on parallel effects in ellipsis constructions, this paper argues that this is due to constraints on Vehicle Change (VC). Whereas a c-commanding coindexed pro prevents an R-expression from undergoing VC, an overt pronoun does not.
