   <hidden TTP98-30  Reparametrization Invariance of Heavy Quark Effective Theory at         O(1/m_Q^3) > We extend the investigation of the reparametrization invariance
 of Heavy Quark Effective Theory to O(1/m_Q^3).
 We show that to this order reparametrization invariance
 can only be maintained if the the reparametrization transformation 
 is renormalized properly.
