The quantum Hall effect, observed in a two-dimensional electron gas subjectedto a perpendicular magnetic field, imposes a 1D-like chiral, downstream,transport of charge carriers along the sample edges. Although this pictureremains valid for electrons and Laughlin's fractional quasiparticles, it nolonger holds for quasiparticles in the so-called hole-conjugate states. Thesestates are expected, when disorder and interactions are weak, to harborupstream charge modes. However, so far, charge currents were observed to flowexclusively downstream in the quantum Hall regime. Studying the canonicalspin-polarized and spin-unpolarized $\nu=2/3$ hole-like states in GaAs-AlGaAsheterostructures, we observed a significant upstream charge current at shortpropagation distances in the spin unpolarized state
