Can cps get a court order for me to release a past private drug /Alcohol ua in a shelter care herring.?

YES, CPS can and will do anything and can do so legally under the "best interest of the child" facade, Children need protection but CPS is out of control and some of the actions they take is harder on the children than what the people are accused of. Back to your question, keep in mind that anything they ask for the judge will grant so they will get the records at some point.}{
