Since then she has remained in the U.S. Marine Corps Reserve and currently is a Colonel. For approximately ten years, she worked as an appellate defense counsel at the Navy-Marine Corps Appellate Review Activity in Washington, D.C.

Ms. Zimmermann has handled many interesting cases as lead counsel in both military and civilian courts. For example:

  • The Court of Appeals for the Armed Forces set aside a guilty verdict, reversing the Air Force Court of Criminal Appeals on an unlawful command influence issue. The Air Force initially planned to retry the case, but later dismissed the charges before trial.
  • The military judge granted her motion to suppress the prior testimony of the complaining witness in an Army rape case, resulting in all charges being dismissed. He was also found not guilty at an Article 15, UCMJ proceeding (nonjudicial punishment) that followed.
  • The state court trial judge granted her motion to suppress all evidence after an illegal police stop, and then acquitted her client in a DWI case when the state completed its case.
  • Although she did not represent him at the first trial, she successfully litigated a Motion for New Trial on behalf of a client convicted of felony intoxication assault in state court. The trial judge set aside the client’s conviction based on the proven claims of the deprivation of Constitutional rights at the first trial.  She remained on the case and on retrial, the client got probation for a Class B misdemeanor.
  • The military judge granted her motion to dismiss a rape charge against an Air Force officer, but the Air Force Court of Criminal Appeals reversed. The Court of Appeals for the Armed Forces then reversed the lower court and dismissed the charge.
  • After an Air Force officer was convicted of sexual assault at trial, she represented him on appeal and the Air Force Court of Criminal Appeals reversed. She prepared to retry the case, but the Air Force dismissed the case after the Article 32, UCMJ preliminary hearing.
  • She represented on appeal an Air Force officer convicted of rape; the Air Force Court of Criminal Appeals upheld the conviction but the Court of Appeals for the Armed Forces reversed the lower court and dismissed the charge.
  • The Air Force Court of Criminal Appeals found legal error and ordered new post-trial processing in the case of an Air Force officer convicted of assault and sentenced to a dismissal from the Air Force; after the appeal, the convening authority approved a sentence without a dismissal.
  • She represented on appeal an Air Force officer convicted of sexual assault; the Air Force Court of Criminal Appeals found the evidence factually insufficient and dismissed the charge.
