Abstract: In a previous paper we have derived the Landau expansion in terms of the 18 real order parameters for the ordered phases of liquid 3He in the presence of a magnetic field starting from a model hamiltonian which contains an l=1 pairing interaction of the BCS type and a contact term of the Hubbard type. In this paper we present a systematic treatment of the extrema of this Landau expansion under a so-called inertia condition which we believe to cover the physically interesting cases.
