Katz-Postal-principle

SEMANTICS: the principle, argued for in Katz & Postal (1964), that all semantic interpretation applies to deep-structure, before the application of transformations. As a result all transformations are meaning preserving. This principle was the source of a deep controversy in generative grammar between generative semantics and interpretative semantics.
