Abstract
Within a general operational framework I show that a-causality at a distance of "local actions" (the so-called "no-signaling") is a direct consequence of commutativity of local transformations, i.e. of dynamical independence. On the other hand, the tensor product of Quantum Mechanics is not just a consequence of such dynamical independence, but needs in addition the Local Observability Principle.
