Lau has recently proposed a generalised theory of gravitation incorporating time-dependent cosmological and gravitational terms which is consistent with Dirac's large numbers hypothesis. It is shown that all vacuum solutions in this theory are identical to those of Einstein's theory with a cosmological constant. In particular, solar system experiments cannot be used to test the theory.
