753.03 Jurisdiction of circuit courts. The circuit courts have the general jurisdiction prescribed for them by article VII of the constitution and have power to issue all writs, process and commissions provided in article VII of the constitution or by the statutes, or which may be necessary to the due execution of the powers vested in them. The circuit courts have power to hear and determine, within their respective circuits, all civil and criminal actions and proceedings unless exclusive jurisdiction is given to some other court; and they have all the powers, according to the usages of courts of law and equity, necessary to the full and complete jurisdiction of the causes and parties and the full and complete administration of justice, and to carry into effect their judgments, orders and other determinations, subject to review by the court of appeals or the supreme court as provided by law. The courts and the judges thereof have power to award all such writs, process and commissions, throughout the state, returnable in the proper county.

The circuit courts are constitutional courts with plenary jurisdiction. They do not depend solely upon statute for their powers. However in certain cases with vast social ramifications not addressed by statute, prudence requires the courts to refuse to exercise their jurisdiction. As such, circuit courts are prohibited from exercising jurisdiction regarding sterilization of incompetents. In Matter of Guardianship of Eberhardy, 102 Wis. 2d 539, 307 N.W.2d 881 (1981).

Because courts have exclusive criminal jurisdiction, criminal charges against a defendant were not collaterally estopped even though a parole revocation hearing examiner concluded that the defendant's acts did not merit parole revocation. State v. Spanbauer, 108 Wis. 2d 548, 322 N.W.2d 511 (Ct. App. 1982).
