  The Transactional Interpretation has been subject at various times to a
challenge based on a type of thought experiment first proposed by Maudlin. It
has been argued by several authors that such experiments do not in fact
constitute a significant problem for the transactional picture. The purpose of
this work is to point out that, when the relativistic level of the
interpretation is considered, Maudlin-type challenges cannot even be mounted,
since the putative 'slow-moving offer wave,' taken as subject to contingent
confirmation, does not exist. This is a consequence of the Davies relativistic
quantum-mechanical version of the direct-action theory together with the
asymmetry between fermionic field sources and bosonic fields. The Maudlin
challenge therefore evaporates completely when the relativistic level of the
theory is taken into account.
