I just received a denial letter of my CWL. I was denied because i was in a mental hospital at the age of 12 or 13 for about 3 weeks. I am now 21. I am serving on active duty in the army national guard. I just don't understand why i was denied because of that so long ago. They said I could file a petition of a district court judge but i don't know how? Can anyone provide any information on this.
