Abstract
For a class of quantifier-free logical theories, axiomatized by conditional equivalences, we prove a completeness result of the form: if a theory T from the class generates the uniquely terminating conditional rewrite rule system, and a partition T1 ∪ T2 of T satisfies certain structural properties, then an arbitrary unquantified formula Ω is a theorem of T1 ∪ T2 iff the leaves of any proof tree for Ω are theorems of T1.
