We comment on the conclusion by Teng et al. [J. Phys. D: Appl. Phys. {\bf 42}, 135111 (2009)] that the Bir-Aronov-Pikus mechanism is more important than the D'yakonov-Perel' mechanism at high carrier density in intrinsic bulk GaAs. We point out that the spin relaxation is solely from the D'yakonov-Perel' mechanism.
