We show that near the transition temperature T/subc/ the relaxation time introduced in Leggett and Takagi's phenomenological theory of spin relaxation in superfluid $sup 3$He is equal to the relaxation time of a normal-state quasiparticle at the Fermi energy at T/subc/, and is independent of the superfluid state. Combescot and Ebisawa's relaxation time is found to diverge as (T/subc/-T)$sup -1$$/$$sup 2$. These results are obtained by deriving and solving exactly the Boltzmann equation for quasiparticles in the superfluid.
