In this era of instant information and background checks these tools are more important than ever before. Whenever a person is charged with a crime, even if the person is found not guilty or the charges are dismissed an arrest record is available to the general public.
Expungement is available for cases where one didn't receive a conviction including:
"Stricken of Call with Leave to Reinstate"
"Finding of No Probable Cause"
Conviction Reversed on Appeal
Supervision Terminated Satisfactorily (this is not available for all crimes including DUI)
710 or 1410 Probation (assuming no other arrests and more than five years has passed)
Convictions for the following Felony Cases:
Class 4 Felony Prostitution
Class 4 Felony Possession of Cannabis (requires the submission of a negative drug test)
Class 4 Felony Possession of Controlled Substance (requires the submission of a negative drug test)
Executive Clemency is available for matters that cannot be sealed or expunged.
These procedures are important so that the accused who has paid his debt to society is able to be successfully re-integrated into society.
