This is another in the protracted series of cases requiring interpretation of section 170.6 of the Code of Civil Procedure. The sole issue turns upon whether a notice of motion to disqualify a trial judge is timely when filed prior to a proceeding on an indirect contempt which is supplementary to a domestic relations action. For the reasons *679 which we set forth below, we have concluded that such notice of motion is not timely.
Dora S. McGlenny, now deceased, 1 initiated a divorce action against defendant James E. McGlenny on October 5, 1961. Judge John F. McCarthy presided at all of the numerous contested hearings in the action. 2 In the year and one-half succeeding the filing of suit Judge McCarthy heard evidence and rendered decisions relating to alimony, custody and support of the McGlenny children, 3 and appointment of a receiver to administer the McClennys ’ property. 4
On April 25, 1963, four and one-half months after Judge McCarthy granted plaintiff an interlocutory decree of divorce and awarded her custody of Eobin Lyn McGlenny, defendant filed a notice of motion requesting that Judge McCarthy modify the custody order by awarding custody of Eobin Lyn to defendant. On the following day plaintiff obtained an order to show cause re contempt, signed by Judge McCarthy, based upon defendant’s refusal to return Eobin Lyn to plaintiff’s custody after a recent visitation period. On May 10, 1963, plaintiff obtained a second order to show cause re contempt, signed by Judge McCarthy, based upon defendant’s sale of several items of personal property in violation of the receivership order and upon defendant’s failure to keep records of money received and obligations paid as required by the receivership order.
Defendant’s motion and the two contempt matters were
*680
noticed for hearing on May 22 before Judge McCarthy. Within five days of the time set for such hearing defendant filed a notice of motion and affidavit of prejudice under section 170.6 of the Code of Civil Procedure seeking to disqualify Judge McCarthy from hearing the pending contempt matters. Judge McCarthy denied the motion to disqualify on the ground that the contempt proceeding was a continuation of the original action within the meaning of
Jacobs
v.
Superior Court
(1959)
Defendant now seeks a writ of prohibition to restrain Judge McCarthy from hearing the pending contempt proceedings.
We turn first to a discussion of several recent cases which have established the principles which control the interpretation to be given section 170.6. We then show how the principles established by these cases apply to the instant ease. We finally indicate why the defendant’s formal categorization of contempt proceedings as quasi-criminal does not suffice to defeat the conclusion that the motion to disqualify was not timely.
Section 170.6 of the Code of Civil Procedure provides that no judge shall try any action or special proceeding when it is established by an affidavit that he is prejudiced against a party or attorney so that the party or attorney cannot, or believes he cannot, obtain a fair and impartial trial before such judge. Pacts showing prejudice need not be alleged or proved; upon the timely making of a motion of disqualification, supported by an affidavit alleging prejudice, the case or matter, without any further act or proof, must be assigned to another judge for trial or hearing. “In no event shall any judge entertain such motion if it be made . .. after swearing in the first witness or the giving of any evidence or after trial of the cause has otherwise commenced.” (Code Civ. Proc., § 170.6, subd. (2).)
In denying defendant’s motion pursuant to section 170.6 the trial court correctly relied upon
Jacobs
v.
Superior Court, supra,
The decision in Jacobs compels us to focus our inquiry upon the single question of whether the contempt proceeding in the instant ease is a continuation of the original domestic relations action or whether it is a separate and independent proceeding.
The result of the Jacobs case has been a catenation of cases fashioning basic rules for determining whether a particular proceeding is a continuation of a prior action or a separate and independent action. These cases fall into two general groups. One group includes those decisions in which the section 170.6 motion is made after the commencement of the principal action but prior to the undertaking of supplementary proceedings. The other includes decisions in which the motion is made prior to the commencement of the principal action but after the undertaking of preliminary proceedings. We proceed to a discussion of both groups of cases.
Several cases have held that a motion pursuant to section 170.6 is riot timely when made prior to supplementary proceedings similar to the instant contempt proceeding. In

(1963)

Several eases have also held that a section 170.6 motion comes too late when filed after the judge has decided preliminary contested matters. Thus in
Michaels
v.
Superior Court
(1960)
*684
Thus the holding in
Jacobs
y.
Superior Court
has been frequently applied, restated, and amplified. . The gravamen of the
Jacobs
decision establishes that a proceeding-is a continuation of the original action out of which it arises if it involves “substantially the same issues” as the original action. The most recent case interpreting the section,
Oak Grove School Dist.
v.
City Title Ins. Co., supra,
In applying to the instant situation the principles announced by the cases, we note the substantial degree of similarity and even identity between the issues to be raised in the pending contempt proceeding and the issues previously presented to Judge McCarthy. A considerable imbrication occurs because in the original proceedings Judge McCarthy considered a broad array of issues relating to the jurisdiction of his court and the validity of the orders allegedly contemned. These issues may properly be urged in the pending contempt proceeding.
(Brady
v.
Superior Court
(1962)
Although the issues to be presented in the contempt proceeding may not be identical in every particular to the issues previously submitted to Judge McCarthy, the questions involving the interpretation of the orders allegedly contemned, and indeed, the issue of whether defendant in fact violated Judge McCarthy’s orders, are “matters
necessarily relevant and material to the issues involved in the
[original] action.”
(Oak Grove School Dist.
v.
City Title Ins. Co., supra,
Finally, as the court said in Jacobs, the “judge who tried the case ... is ordinarily in the best position to pass upon the questions involved,” and to hear matters involving the same or closely related issues. (Jacobs v. Superior Court, supra, 53 *685 Cal.2d 187, 191.) The instant action has been in Judge McCarthy’s court for over a year and one-half. 12 Prior to the hearing on the section 170.6 motion Judge McCarthy has presided at seven separate hearings involving contested issues in the ease. 13 Some of these contested matters involve difficult problems raised in a determination of child custody; others involve highly complex problems relating to the receivership of the family assets. 14 Judge McCarthy is the only judge familiar with the extensive and complicated facts and issues of this litigation. In the words of the Jacobs case, Judge McCarthy is “in the best position to pass upon the questions involved.” (Id. at p. 191.)
Turning to defendant’s countercontention, we note that he relies upon the quasi-criminal nature of contempt proceedings in presenting a twofold proposition. He first argues that because he may suffer criminal sanctions by virtue of the contempt proceeding, we should resolve all judicial doubt in his favor by sustaining the timeliness of his motion; he next contends that the quasi-criminal nature of contempt in itself converts the proceeding into a separate action.
As to the first argument, section 170.6 draws no distinction between civil and criminal actions.

Superior Court, supra,
Chief Justice Gibson, writing in
Pappa
v.
Superior Court, supra,
As we have stated, defendant’s second position rests upon the theory that we must hold that contempt proceedings are separate
because
they are quasi-criminal in nature. Dictum in the case of
In re Gould
(1961)
*687
We have noted
supra
that
Pappa
rejects an interpretation of section 170.6 which emphasizes the criminal nature of the proceeding in question. Moreover,
Pappa
makes it clear that section 170,6 is not to be treated as a “procedural safeguard” in the sense meant by the dictum in
In re Gould.
The issue in
Pappa
turned upon whether the two defendants held adverse interests for purposes of deciding if each of them would be. entitled to a section 170.6 challenge. The court distinguished cases defining adverseness for purposes of the constitutional right to counsel, stating that, [a] different situation is presented where, as here, a limited privilege is involved which would not be available in the absence of a special statute and cannot be exercised except in accordance with that statute.” (
In any event, the dictum in In re Gould cannot be considered an immutable prescript. The cases have clearly held that contempt proceedings for some purposes do constitute continuations of the action from which they emanate. In a situation analogous to the instant case, the courts of this state have consistently ruled that indirect contempt proceedings may be maintained against a party over whom the court acquired personal jurisdiction in the principal cause, although notice of the order to show cause in the contempt matter was served only on the alleged contemner’s attorney. 19
Thus the proper resolution of the present case cannot rest upon defendant’s formal categorization of contempt as quasi-criminal; a more fruitful approach lies in an evaluation of the actual function performed by the contempt proceeding. In domestic relations cases in particular, that function is one of enforcement of the court’s orders. As the respondent court explained: “In deciding this question, consideration should *688 be given to the fact that ... [although] generally contempt proceedings are considered as separate criminal proceedings, it would appear that dbinestic -relations actions are peculiar in this respect—that for the support and custody of minor children, as well as other domestic relations matters, the decrees of the court-must constantly be implemented by supplementary proceedings' in the nature of contempt. ” 20
In domestic relations actions the courts must exercise a continuing jurisdiction- over the parties and over the subject matter of the action.
21
The trial court must perform continuing supervisory - and enforcing functions, and the contempt proceeding is one of the court’s two principal means of performing these functions.
22
In the early case of
Mitchell
v.
Superior Court
(1912)
To hold that the contempt proceeding in the present case constitutes a separate and independent action would unduly impede the administration of justice. As respondent court *689 recognized, “many defendants are constantly before the courts on contempt matters, and if each of these is to be considered a separate proceeding for the purpose of section 170.6, a not inconsiderable amount of judicial juggling will be required. ”
Acceptance of defendant’s position would permit litigants to obtain, by repeated cycles of a contemptuous act and a motion based upon section 170.6, a perpetually fresh fdrum for testing disadvantageous decisions. We cannot ignore in defendant’s position the potentiality for abuse of section
170.6. We cannot permit a device intended for spare and protective use to be converted into a weapon of offense j and thereby to become an obstruction to efficient judicial administration.
We conclude that the contempt proceeding in the instant action is a continuation of the original domestic relations action, and that Judge McCarthy properly denied defendant’s motion under section 170.6.
The alternative writ is discharged and the petition for a peremptory writ is denied.
Gibson, C. J., Traynor, J., Schauer, J., McComb. J., Peters, J., and Peek, J., concurred.
Notes
Mrs. McGlenny’s estate is represented in this action by a special administrator, the Farmers and Merchants Trust Company of Long Beach.
The following matters were tried before Judge McCarthy: the initial contested hearing on alimony pendente lite, child custody, and child support of October 25, 1961; the initial contested hearing on the appointment of a receiver of January 17, 31 and February 23, 1962; the contested hearing on the expansion of the receivership of July 18 and 19, 1962; the contested hearing on the modification of support awards of July 27, 1962; the hearing resulting in the interlocutory decree of December 13, 1962; the contested hearing on defendant’s motion to dissolve the receivership of March 5, 1963.
The court awarded custody of Robert Wayne and Debra Sue MeClenny to defendant, and Robin Lyn McGlenny to plaintiff.
The court ordered a receiver to take possession of all of the real and personal property of both plaintiff and defendant, to collect all rents, issues, and profits of the property, and to pay plaintiff alimony and child support in accordance with the court’s orders. The court expressly enjoined both parties from interfering with the activities of the receiver and ordered them to deliver any property in their possession to the receiver.
The court’s holding is summarized in the following statement: “If a disqualification were permitted under section 170.6 in matters which are continuations of a prior proceeding, it would mean that the judge who tried the case, and who is ordinarily in the best position to pass upon the questions involved, could by a mere general allegation of prejudice ... be disqualified from hearing such matters as motions for modification of a support order or an injunction, as well as motions for change of custody of children. Such procedure would make it possible for litigants to gamble on obtaining a favorable decision from one judge, and then, if confronted with an adverse judgment, allow them to disqualify him without presenting facts showing prejudice, in the hope of securing a different ruling from another judge in supplementary proceedings involving substantially the same issues.” (Id. at p. 191.)

Defendant waived findings of fact to the August 2, 1962, order expanding the receivership. The order followed two full days of testimony before Judge McCarthy. The pending contempt proceeding involves alleged violations by defendant of the August 2 order, and Judge McCarthy is the only judge who knows the evidence upon which he based the order.
Section 170.6, as originally enacted in 1957 did not provide for disqualification in criminal cases. The court in

The Legislature enacted a predecessor to section 170.6 in 1937. This statute, Code of Civil Procedure section 170.5, was identical in substantive effect to the present section 170.6, except that it did not require an affidavit of bias or prejudice. In 1938 this court held section 170.5 unconstitutional on the ground that it constituted an unwarranted interference with the orderly processes of the courts.
