 The Commission intended to correct the problem of inconsistent multiple orders by only allowing the support orders to be modified based upon a single state's law.In theory, states A, B and C could only modify a support order based upon the original state's substantive law; thus, all the support orders should be identical.In practice, however, this rule created ambiguities concerning whether child support guidelines are procedural or substantive, and if substantive, whether application of that substantive law contravened some public policy.
