An “Adjournment of Contemplation of Dismissal (ACOD)” is an adjournment of the action without date ordered with a view to ultimate dismissal of the accusatory instrument in furtherance of justice.  The granting of an ACOD shall not be deemed to be a conviction or an admission of guilt.  Upon the dismissal of the accusatory instrument, the arrest and prosecution shall be deemed a nullity and the defendant shall be restored, in contemplation of law, to the status he occupied before his arrest and prosecution.
