We present a new calculation of the renormalized HQET Lagrangian at order
O(1/m_Q^2) and discuss the consequences of the BRST invariance of QCD and the
reparameterization invariance of HQET. Our result corrects earlier, conflicting
calculations and sets the stage for the calculation of the renormalized
currents at order O(1/m_Q^2).
