  We report a partial-wave analysis of new data on the double-polarization
variable $E$ for the reactions $\gamma p\to \pi^+ n$ and $\gamma p\to \pi^0 p$
and of further data published earlier. The analysis within the Bonn-Gatchina
(BnGa) formalism reveals evidence for a poorly known baryon resonance, the
one-star $\Delta(2200)7/2^-$. This is the lowest-mass $\Delta^*$ resonance with
spin-parity $J^P=7/2^-$. Its mass is significantly higher than the mass of its
parity partner $\Delta(1950)7/2^+$ which is the lowest-mass $\Delta^*$
resonance with spin-parity $J^P=7/2^+$. It has been suggested that chiral
symmetry might be restored in the high-mass region of hadron excitations, and
that these two resonances should be degenerate in mass. Our findings are in
conflict with this prediction.
