  In this short note, we prove a comparision theorem between Levine-Serp\'e's
equivariant higher Chow groups of an algebraic variety equipped with an action
of a finite group and ordinary higher Chow groups of its fixed points. As a
consequence, we show that the equivariant motivic spectral sequence degenerates
rationally. This yields a Riemann-Roch Theorem for equivariant algebraic
$K$-theory.
