  This chapter of the proceedings for the Ninth Meeting on CPT and Lorentz
Symmetry is dedicated to the Hamiltonian formulation of the minimal
gravitational Standard-Model Extension. Some theoretical questions associated
with the latter shall be reviewed. First, we recall the properties of the
Hamiltonian, which was computed elsewhere, and discuss how it is linked to the
modified Einstein equations. Second, we describe how the covariant and
Hamiltonian formulations are shown to be consistent with each other.
