  The first evidence of anomalous Josephson effect is reported in mesoscopic
superconductor-normal metal-superconductor (SNS) junctions forming a crosslike
Andreev Interferometer in the absence of magnetic and spin-orbit interactions
normally required to break time-reversal and inversion symmetries. From
conductance measurements of the out-of-equilibrium weak link, we determine a
voltage-controlled spontaneous phase that resembles a $\varphi_0$-junction. The
temperature and voltage dependences together with a dissipative term in the
current-phase relation strongly suggest that the mechanism underlying the
observed phenomenon relies on electron-hole asymmetries.
