Abstract
A locality condition on the θ-role assignment is proposed and the Case Criterion, a combination of the Case Filter and the Case Realization Condition, is formulated in terms of the notion of chain. It is shown that the distributional properties of clausal arguments are explained by these fairly simple conditions together with other principles in UG. It is also noted that the theory in this paper, if correct, will constitute a counterargument to the Visibility Hypothesis proposed in the recent literature of GB theory.
