RES(NIC) is not related to NIC or to the binding theory at all, but rather to a different principle of the theory of government, still to be formulated properly, namely, the principle that traces must be in some sense governed at LF.
- Chomsky (1993), Pag. 233

RES(NIC) extends beyond "wh"-trace to variables in general and thus is a principle applying in the LF-component, presumably, as a condition on LF-representation.
- Chomsky (1993), Pag. 239

We may now tentatively reformulate RES(NIC) as in (4): (4) [NP "e"] must be locally controlled.
- Chomsky (1993), Pag. 241

[…] let us simply take "local control" to be a subcase of government [...] Then RES(NIC) is reformulated as (7): (7) [NP "e"] must be governed (in some sense).
- Chomsky (1993), Pag. 249

Some distinct principle, then, will account for the fact that "wh"-movement appears to the subject to something like the NIC [...] call it "the residue of the NIC" (RES(NIC)) […].
