  We report on a microscopic Refined Resonating Group Model (RRGM) calculation
of scattering of $p$ off ${}^3{\rm He}$ employing the Argonne-$v_{14}$ and the
Bonn nucleon-nucleon potentials without three-nucleon forces at low energies up
to 30 MeV. The calculated phase-shifts verify the well-known proton analyzing
power $A_y$-problem. We demonstrate that with corrected ${}^3P_2$ phase-shifts
experimental differential cross-section and analyzing power data can be
explained.
