Any person can make a claim to CPS and CPS must act on these claims, regardless. Since they have to investigate and CPS has pretty much unlimited powers in dealing with children. If you had a signed agreement with CPS and they violated that signed agreement, then you could have a breach of contract claim against them. Additionally, what you could have is a suit under state law for a violation of your constitutional rights if they unlawfully used the information against you in direct contravention to the law. However, the rules of evidence are for use in the courtroom, not in enforcement or investigative matters, therefore, you cannot hang your hat on that as the basis for your suit. You should hire an attorney to represent you and file your complaint against CPS and if you cannot afford an attorney ask the state bar about the pro bono programs in your area.
