After 15 years of closure with cps can they used against you? Can we file to be revert?

In 2001 cps charge me with eminent danger to my 4 kids because a was married to a Dr. That was charge with dui , but 4 month later they return my kids back to my the natural mother he was the step father. Case was completely close in September if 2002 saying this case is dismissed and close from the court ducked. Now after 15 years I The cps has place under my care my granddaughter age 1 months 1/2 and after 13 month they ask me to do a Homefinding process and my case of 15 that I wasn't guilty of any drugs, abused directly to any of my children but yet they using that initial intake to remove my granddaughter and place with the natural mother who was trying to commit suicide 2 in 3 month and have a mister minor put in jell for lifting to the court and yet they said that is a better place. I have never see such of tragedies again a person that all alone never hurt one of my kids or done never drugs, never alcohol or any think agains the law but yet they removed her now 1 year and 2 month with the same allegations saying my home is not qualified to care for her??? Please is one out their can see why this is so wrong and what can I do other then plead the judge to place her back.
