In this paper we present and discuss the relativistic correlation function in a bipartite system of two electrons, originating from the $e^{-}{e}^{-}e^{-}{e}^{-}$ scattering of a polarized electron beam on an unpolarized target. We also calculate and investigate the probabilities of the definite outcomes of spin-projection measurements performed by two observers. The presented results might help in experimentally verifying whether relativistic quantum theory is able to reproduce the behavior of real quantum systems.
