This paper began with pointing with the theoretical weaknesses of the Chain Uniformity Condition (CUC) which is based on the uniformity condition (Chomsky, 1992; Chomsky & Lasnik, 1993). To solve the problems, I introduced the refined CUC and Barriers with a new adjunction condition that is adopted from Frampton (1990). Concerning the problems raised by subject/object asymmetry and Wh-in-situ constructions, I have introduced a [+p] feature (Watanabe, 1991). In order to develop a more general theory, I have separated the I-to-C Raising (or [T+AGRs]-to-C Raising) into two parts: the one part occurring before Spell-Out by [+p], and the other after Spell-Out by [T+AGRs]. I assumed that erasure of offending traces in the Spec of AGRsP in the overt syntax through L-marking by [+p] does not influence the judgement of grammaticality at all. I have shown that with the help of the constraints developed in this paper we can explain the cases of the movement of Wh-in-situ at LF.
