\textsc{Abstract:}
This is a joint work with Prof. Ilan Hirshberg and Dr. Tattwamasi Amrutam.
Let $\Gamma$  be a discrete group with the property-AP. We give conditions for the inclusion of unital separable  C\emph{-algebras $A \subset B$  for 
which every intermediate  C}-algebra $C$, such that $A \rtimes \Gamma \subset C \subset B \rtimes \Gamma$  is a crossed product. We shall end 
this talk with some natural classes of inclusion satisfying the above mentioned conditions.
