We have proven rigidity for the Lichnerowicz-type eigenvalue estimate for the Kohn Laplacian on strictly pseudoconvex three manifolds with nonnegative CR Paneitz operator and positive Webster curvature. This conditions for this rigidity include the manifold having a nonnegative CR Paneitz operator and positive Webster curvature.
