Can’t understand why a state prosecutor would be involved in a civil case nor why said prosecutor would have anything to do, one way or the other, with immunity.
Civil cases are between private parties and are litigated by private attorneys.
Because it was originally sent to prosecutors for criminal charges but they dropped the charges due to lack of evidence. Shortly after a civil case was settled out of court where he made the statements that he drugged to women in order to assault them. Then criminal case happened. As the criminal case proceeded, the trial court — and an intermediate appeals court — found that no formal non-prosecution agreement ever existed. Yada, yada, yada.
