On February 7,1963, the plaintiff was arrested under two bench warrants issued by the Superior Court pursuant to original informations filed by the state’s attorney. One information, in two counts, charged the plaintiff with the crime of kidnapping in violation of General Statutes § 53-27 and with the crime of rape in violation of General *593 Statutes §53-238. The other information charged him with the crime of robbery with violence in violation of General Statutes §53-14. The prevailing Connecticut procedure was followed in conformity with General Statutes § 54-43 so that the warrants were issued without facts supported by oath or affirmation from which the judge or court could independently determine that probable cause existed for their issuance. On February 8, 1963, the plaintiff was presented in the Superior Court and pleaded not guilty to all three counts. On February 14, 1963, he was again presented and, on that date, pleaded guilty to all three counts. On both appearances before the Superior Court he was represented by experienced counsel.
On March 12, 1963, the court adjudged him guilty on all counts and sentenced him to imprisonment in the state prison. He took no appeal and was committed to prison, where he has since been confined. The period allowed for an appeal expired in March, 1963. General Statutes § 54-95; Practice Book § 601.
On November 9, 1965, this court decided, in
State
v.
Licari,
*594 Thereafter, on January 18, 1966, the plaintiff, acting pro se, filed the present application for a writ of habeas corpus in which he sought “an order dismissing the information against him, [and] directing his immediate release.” The writ issued, and, on February 24, 1966, the court appointed counsel to represent the plaintiff. Following a hearing, the court, on June 28,1966, dismissed the plaintiff’s petition and thereafter granted his application for a review, by this court, of “the question of whether or not the Licari doctrine should be given retrospective application” to the plaintiff’s case.
The parties have made no issue, and consequently we need not decide, whether habeas corpus is a proper vehicle to raise the question presented. Habeas corpus provides a special and extraordinary legal remedy for illegal detention.
Bissing
v.
Turkington,
The plaintiff does not complain that either information failed adequately to inform him of the charges made against him. His guilt of those charges is admitted. No claim is made, nor could one properly be made, that, when the plaintiff was adjudged guilty, the Superior Court lacked jurisdiction of the subject matter. Gfeneral Statutes §§ 54-17, 54-42. His only claim is that his conviction must be set aside because the arrest warrants by which he was brought before the court were, if the Licari case is given restrospective effect, illegal.
In six récent criminal cases we have accorded partial retrospective application to changes in the law announced by the United States Supreme Court.
State
v.
Wilkas,
*596
We have twice dealt with the retrospective application of overruling decisions in civil cases.
Chykirda
v.
Yanush,
The United States constitution neither requires nor prohibits the retrospective application of a decision overturning prior pronouncements of the law.
Linkletter
v.
Walker,
The
Licari
case “amounted merely to a recognition and acceptance, and, indeed, an application, by Connecticut of settled law as laid down by the Supreme Court of the United States in cases such as
Giordenello
v.
United States,
In the present case, the state claims that, by his pleas of not guilty and guilty, while represented by experienced counsel, the plaintiff consented to the jurisdiction over his person and waived any defect in the bench warrants.
State
v.
Bishop,
It is the proper presentment of the information— not the arrest — which is essential to initiate a criminal proceeding.
Tracy
v.
Williams, 4
Conn. 107, 112. Arrest and detention are primarily for security purposes and not for the purpose of conferring jurisdiction. See
Pelak
v.
Karpa, 146
Conn. 370, 372,
On two recent occasions, the validity of bench warrants has been attacked on the authority of the
Lic'ari
case. In
State
v.
Darwin,
The proper way to raise an issue of an illegal arrest is by a plea to the jurisdiction. In proper sequence, such a pleading must precede the joinder of issue on the information by a plea of not guilty or guilty. The effect of the failure to make such
*600
a plea to the jurisdiction is to waive the question of the jurisdiction of the person.
Ford
v.
United States,
The plaintiff suggests to us no way in which he has been denied due process of law or has suffered prejudice requiring a retrospective application of the Licari case. He was charged with three very serious crimes and was convicted on his own admission of his guilt. The state did not, as it did in the Licari case, fail to contest the claim that the accused had not consented to the jurisdiction of his person and waived the illegality of the warrants.
A question of jurisdiction, which may not be waived or which may not be conferred by consent, must, of course, be considered and decided whenever it appears. No such question was present in the Licari case because, as already stated, the issue of *601 jurisdiction of the person present in that ease, unlike jurisdiction of the subject matter, could be consented to or waived.
In the case now before us, the state has claimed that the plaintiff did, by pleading to the informations, waive the illegality of the warrants and consent to the jurisdiction of his person. The burden of proof on that issue rested on the state.
State
v.
Licari,
The fundamental basis for testing whether a decision should be given retrospective effect is whether the rule which it lays down goes “to the fairness of the trial — the very integrity of the fact-finding process.”
Linkletter
v.
Walker,
There is no error.
In this opinion the other judges concurred.
