What is the name of your state? NY If in your past, as a teenager, and in twenties, you were arrested and received an ACD, didn't get in trouble again with these incidents, but approximately 10 years later you have a situation where the DA wants to have hearing to see if she can bring up your past, I was always led to believe that an ACD was sealed after 6 months as long as you didn't get into trouble, so if it is a sealed document how can she open it after 10 + years.
