This paper presents a formulation of continuum theory for biaxial nematic liquid crystals based upon balance laws for linear and angular momentum, and derives directly expressions for stress and couple stress. The theory so obtained is more general than the earlier theory by Saupe, having more terms in the viscous stress, but by determining conditions that this stress is derivable from a dissipation function, one recovers his version, this requiring four Onsager-Parodi relations.
