This is an appeal from an order taxing costs in a disqualification proceeding,1 dated May 12, 1966, and entered May 14, 1966, in the Wayne county circuit court by visiting circuit judge Fred N. . Searl. The facts are well stated in Judge Searl’s *27opinion granting respondent’s motion to assess costs, as follows:

“The principal case of Harvey v. Lewis has been in the courts since 1952, see opinion in Harvey v. Lewis, (1959), 357 Mich 305. Circuit judge John V. Brennan was originally assigned the case and filed an opinion on the merits of the original controversy. Subsequently a receiver was appointed. Judge Rashid entered the case in 1957, after other judges who had heard it either died, retired or became disqualified.

“In January or February 1966 plaintiffs filed a petition to disqualify Judge Rashid and it was heard before the writer of this opinion, who was assigned the case by the court administrator. After a two-day trial and at the conclusion of plaintiffs’ testimony, a motion to dismiss was granted, and subsequently an order entered dismissing the petition to disqualify.

“The proofs consisted of the claims (1) that Judge Rashid made erroneous orders in the receivership matter; (2) that in 1952 when he was an assistant prosecutor he had taken part in a coroner’s inquest involving a member of the Lewis family, some members of which are defendants here; and (3) that an employee of the receiver has been incompetent or worse.

“There was offered no evidence to show any connection between Judge Rashid and the Lewis family in the years that followed 1952, and there was no evidence of any kind indicating that Judge Rashid had any prejudice or bias in fact.

“As stated, Judge Rashid had been acting in the ease some 9 years and in that period of time it appeared that plaintiffs had taken at least 19 appeals and had prevailed in none of them. One is pending at the present time in the Court of Appeals.

“In one of the appeals the Court stated, 364 Mich 494;

*28“ ‘Per Curiam. Appeal dismissed for failure to comply with order of May 2, 1961, appellants’ brief and appendix being grossly lacking in tbe requirements of propriety and grossly disregarding the requirements of a fair presentation of tbe issues involved to tbe Court. Court Rule No 70, § 5 (1945). Case remanded to circuit judge for assessment of damages. Greenough v. Greenough (1958), 354 Mich 508; Harden v. Widovich (1960), 359 Mich 566 and 361 Mich 422. Costs to appellees.’ ”

Appellants raise 2 issues on appeal: (1) May a circuit judge after a full bearing on a petition to disqualify another circuit judge exercise discretion to assess costs, including reasonable attorney fees, against tbe petitioner under GCR 1963, 111.6? (2) Is a question of public policy involved in a good faith disqualification proceeding ?

Tbe statutory authority to tax costs is set forth in chapter 24 of PA 1961, No 236 (CLS 1961, § 600-.2401 et seq. [Stat Ann 1962 Rev § 27A.2401 et seq.]). Section 2401 provides in part:

“Except as otherwise provided by statute, tbe supreme court shall by rule regulate the taxation of costs.”

Section 2405 provides in part:

“Tbe following items may be taxed and awarded as costs unless otherwise directed:

“(2) Matters specially made taxable elsewhere in tbe statutes or rules. * * *

“(6) Any attorney fees authorized by statute or by court rule.”

Respondent and appellee relies on tbe authority granted to tax costs in special matters as provided in GCR 1963, 111.6:

“Unwarranted Allegations and Denials. If it appears at the trial that any faot alleged or denied by *29a pleading ought not to have been so alleged or denied and such fact if alleged is not proved or if denied is proved or admitted, the court may, if the allegation or denial is unreasonable, require the party making such allegation or denial to pay to the adverse party the reasonable expenses incurred in proving or preparing to prove or disprove such fact as the case may be, including reasonable attorney fees.”

Appellants do not cite and we fail to find any statute concerning costs applicable to unwarranted allegations and denials in pleadings.2 In the absence of such a statute, we conclude the court rule in question is operative.

Plaintiffs assert that the appellee, Judge Rashid, is not an adverse party and therefore cannot claim costs under GCR 1963, 111.6. It is conceded that he is a respondent. However, plaintiffs fail to cite any authority indicating that a respondent in disqualification proceedings is not an adverse party.

The word “adverse” in legal proceedings has been said to be equivalent to or synonymous with “opposing” and “opposite.” 2 CJS, Adverse, p 503. It is quite evident that Judge Rashid stood opposite plaintiffs. His adverse position is evidenced not only by the various pleadings and memoranda entered, but also by the 2 days of hearing on the motion to disqualify. The narrow question therefore becomes: Was respondent Judge Rashid a party to the disqualification proceeding ?

In 54 CJ, Respondent, p 726, it is stated in part as follows:

*30“Any one who answers or responds may properly he called a ‘respondent/ ‘Respondent’ is not a technical word, bnt is often used as meaning the defendant in a snit in personam or the claimant in a snit in rem. Originally, ‘respondent’ was the term used to designate the person against whom a bill in equity was exhibited; the party who makes an answer to a bill or other proceeding in chancery; the person upon whom an ordinary petition in the court of chancery, or a libel in admiralty, is served, and who is, as it were, a defendant thereto.” (Footnotes omitted; Emphasis supplied.)

Through counsel, Judge Rashid answered the motion to disqualify, and plaintiffs’ subsequent reply to this answer stated:

“A. Plaintiffs:

“1. Deny that said answer is by A. Albert Sugar or by any other ‘attorney’ and say that since it is signed and verified by respondent it is Judge Rashid’s answer.”

This Court has been unable to find any case directly on point in this jurisdiction. For the reasons herein stated concerning the general rule of law applicable to “respondents” we find the term “adverse party” as set forth in GfCR 1963, 111.6 to encompass the respondent circuit judge named in the motion to disqualify brought under GCR 1963, 405.

Judge Searl made certain findings in his opinion granting repondent’s motion for awarding costs. We repeat them here as follows:

“Turning now to rule 111.6. Did it appear at the trial that any fact alleged by the plaintiffs’ motion to disqualify ‘ought not to have been so alleged’ ?

“The court found that none of the grounds set forth for the alleged disqualification were sustained.

“1. There was not a scintilla of evidence to support the charge that Judge Rashid was biased or *31prejudiced, in fact, in favor of or against either the plaintiffs or the defendants.

“2. The allegation that Judge Rashid had made erroneous orders was wholly without merit. ‘Prejudice or bias can never be based solely upon a decision in the due course of judicial proceedings.’ Justice Wiest in Crowley, Milner & Co. v. Macomb Circuit Judge (1927), 239 Mich 605, 613. To the same effect is Kolowich v. Ferguson (1933), 264 Mich 668; Mahlen Land Corp. v. Kurts (1959), 355 Mich 340, 350.

“Moreover, there was no proof of erroneous decisions. One decision is presently being appealed to the Court of Appeals. Plaintiffs attempted to appeal 19 others and met with no success in any of them. For examples of some of these appeals, see Harvey v. Lewis (1961), 363 Mich 232; Harvey v. Lewis (1961), 364 Mich 493.

“3. The allegation of disqualification because of misconduct of an employee was equally without merit. Counsel for plaintiffs attempted to show some connection between Judge Rashid and the employee, but wholly failed. The nearest thing to proof was the fact that as assistant prosecuting attorney he had apparently questioned the employee during the course of the 1952 inquest, and some photographer had taken a picture while he was talking to the employee. Much more connection between plaintiffs’ counsel and the employee was shown. In Judge Brennan’s opinion, which plaintiffs offered in evidence, the employee was described as a member of plaintiffs’ counsel’s legal household. Whether this conclusion was warranted was not an issue in the disqualification case and was not decided. The fact remains that there was no evidence that connected Judge Rashid with the employee in any regard.

“This brief review makes it abundantly clear to the mind of the judge who heard the matter, at least, the allegations made by plaintiffs were wholly with out merit and should not have been made.

*32“Judge Rashid was placed in a position, where he could have 3 choices: One, he could permit the matter to proceed without contest on his part and thus give the impression that he did not deny the truth of the allegations made. Secondly, he could appear in person, a course that has never been recommended for lawyers and certainly not for judges. Finally, he could employ counsel to adequately represent him. He followed the latter course, and this I believe was fully justified.

“Naturally the attorney who had to review 13 years of litigation had to spend much more time than would usually be required to defend a disqualification motion. There is no evidence to dispute the claim that he spent 60 hours, which included 2 days in court. Nor is there any dispute that $25.00 per hour is a fair charge to be made in the city of Detroit.

“The question is, who is going to stand the loss, Judge Rashid, the attorney who rendered the services, or the plaintiffs who brought the unwarranted proceedings ?

“I find that Judge Rashid is entitled to receive from plaintiffs the reasonable expenses incurred in the preparation and trial necessary to defend the unwarranted charges made against him ‘including reasonable attorney fees.’ I also find that $1,500 is a reasonable attorney fee.” (Emphasis supplied.)

The findings of Judge Searl under the facts were proper and fully justified. We agree that the plaintiffs’ allegations of prejudice and bias were made without any factual basis and were unreasonable and therefore should not have been made. A circuit judge whose integrity, probity and candor is questioned in a motion to disqualify has a duty to defend the conduct of the court in which he is presiding. This is especially true where after acting in a case for some 9 years, unwarranted allegations of prejudice and bias are made. The reasonableness of the *33attorney fees has not been questioned on this appeal, nor do we question them.

Plaintiffs word their second issue thus: Is a question of public policy involved in a good faith disqualification proceeding ?

In equitable proceedings involving questions of public interest or public policy the Supreme Court denies costs where the matters for its consideration are apparently brought in good faith. Case v. City of Saginaw (1939), 291 Mich 130; White v. Welsh (1939), 291 Mich 636; Lewick v. Glazier (1898), 116 Mich 493; School District No. Thirteen v. Dean (1868), 17 Mich 223; People v. Auditors of Wayne County (1858), 5 Mich 223.

The question as posed of whether there is immunity from taxation of costs because of public policy need not be considered where plaintiffs are shown not to have proceeded in good faith.

The overall record bears out the trial court’s finding of an absence of a good faith proceeding. Therefore, plaintiffs are not to be cloaked with an immunity which otherwise might have been present were a good faith proceeding undertaken; The rule concerning no costs to be awarded because of public policy has no application here.

The taxation of costs is neither a reward granted the prevailing party nor a punishment imposed on the losing party. It is but a part of the burden of litigation and this is presumed to have been known by plaintiffs when bringing their petition.

Affirmed. Costs to appellee.

(dissenting). In my opinion the rule permitting the assessment of reasonable costs for unreasonable allegations or denials is intended to *34cover bad faith pleading. I have so concluded not only because I believe that where access to the courts is involved an objective standard is essential for the sound administration of justice, but also because it appears that, when first promulgated, it was expressly stated the rule was intended to cover “bad faith” pleading.

Michigan is a fact-pleading State, and both the language and history of the rule indicate an intention to cover only underlying facts unreasonably pleaded rather than ultimate fact.

I.

GCR 1963, 111.6 [for full text, see majority opinion, page 28] first appeared substantially in its present form as rule No 17, § 10, Michigan Court Rules (1931).1 The 1931 rules were adopted on the basis of work done by a commission established pursuant to PA 1927, No 377. The commission’s final amended report contains the following explanation of that section:

“This section is new and is intended to discourage denials made in bad faith.”2

Thus, the provision before us was designed to discourage bad faith pleading, first as to denials only and later, by amendment effective in 1963,3 allegations as well as denials. The basic language is the

*35same and the gloss on the rule set forth in the report of the commission remains.

It also appears that while the format of the 1931 section was new, the concept was not entirely new. Sections 7 and 8 of rule 23, Michigan Circuit Court Rules (1916), provided the defendant shall pay to the plaintiff the reasonable expense incurred by the plaintiff in proving or preparing to prove the material allegations the defendant shall not in good faith have intended to controvert. It is this concept of penalizing denials not in good faith (circuit court rules of 1916) and bad faith denials (court rules of 1931) carried forward subsequently for both allegations and denials (general court rules of 1963) that is before us.

There are substantial policy reasons for limiting the rule’s application to bad faith pleading, as its history indicates it was intended to be limited. Countless lawsuits are started or defended on a subjective belief in their merits, rather than after an objective determination of reasonable or probable cause for entertaining such belief. Lawyer or litigant may properly rely on the discovery procedures designed to assist one in proving pleaded allegations or denials. A litigant is not expected to establish he has reason to believe he will be able to prove a fact before proceeding with discovery in respect to that fact.4 Nor may he be penalized with the cost of discovery or other proceedings because after exhausting discovery he is unable to establish a fact sought to be proved.

*36Unless the operative effect of GrCR 1963, 111.6 is limited to those situations where it was known at the time the fact was pleaded that it conld not he proved,5 the rule could he utilized to penalize any litigant who fails to prove any fact essential to his case. Lawsuits commenced and defended with a hope and a prayer have proved successful. Litigants have obtained evidence which they had no assurance they could obtain at the time they pleaded, or indeed any reasonable expectation of being able to obtain. As the result of vigorous preparation or happenstance, the truth came out, the fact was proven and a meritorious position vindicated. The majority would penalize those not so fortunate and permit a trial judge to impose the entire cost of the lawsuit on the unsuccessful litigant if, on the basis of failure to have produced evidence supporting a fact pleaded, the judge concludes the allegation or denial of that fact was “unreasonable.” Failure of proof will then become the basis for assessment of actual costs in the trial judge’s discretion as a matter of course, subject to our limited powers of review.

II.

The trial judge’s findings resolve6 into 2 basic propositions, (1) that some of the arguments advanced by petitioners were legally insufficient, i.e., *37those concerning allegedly erroneous orders, and (2) that there was a failure to offer any evidence the judge sought to be disqualified was prejudiced.

Surely, the order appealed from should be set aside to the extent the award is apportionable to the successful legal argument that petitioners’ allegations were legally insufficient, or to preparation to disprove such legally insufficient allegations. There can be no justification for awarding “reasonable expenses incurred in proving or preparing to prove or disprove such fact”, if the fact is insufficient as a matter of law, as then there is no need factually to disprove it. If it be said the successful counsel might or could not have known in advance the court would rule favorably on his claim the allegations were legally insufficient, then how can it properly be held — if successful counsel is in doubt as to the outcome — that the unsuccessful litigant made allegations which “ought not to have been” made or that were “unreasonable.”

The trial judge did not find the petitioners proceeded in bad faith. It appears from his findings *38that he concluded he was authorized to make an award because he had found petitioners failed to produce any evidence in support of their petition to disqualify. That should not be enough. Failure of proof is not uncommon. It would radically transform the opportunity to litigate meritorious cases if the unsuccessful litigant legitimately may fear that upon the conclusion of the trial the fact of failure of proof coupled with the trial judge’s subjective evaluation of the reasonablenes of such failure could, if such determination is adverse to the unsuccessful litigant, result in the assessment of all the expenses of the lawsuit against him.

Unless controlled by an objective standard, there is real danger the power to assess reasonable expenses could and would be employed ad hominem against unpopular lawyers or litigants and ad hoc to discourage unpopular complaints or defenses. If the standard is subjective, it might prove difficult to avoid focus, albeit not intentionally, on the attorneys or litigants involved and the trial judge’s general reaction to the case.

It is, I think, significant that while there are numerous rules and decisions concerning the power of appellate courts7 to tax costs where an appeal is brought in bad faith, little has been done in regard to the same problem at the trial level.8 Perhaps this is because of the difficulty of appraising bad faith at the trial level and the danger of unduly discouraging meritorious presentations.9

*39III.

The rule speaks of a fact alleged or denied and the expenses of “proving or preparing to prove or disprove such fact.” I think it apparent from the language and history of the rule that “fact” means underlying fact rather than ultimate fact.

Michigan is a fact-pleading State.10 A comparison of sections 7 and 8 of rule 23 of the circuit court rules (1916) shows that the distinction between the underlying fact and all the facts was then recognized.11 The concept carried forward from those rules to the 1931 rules and from the 1931 rules to the 1963 rules was that for bad faith pleading in respect to an underlying fact, the cost of proving or preparing to prove or disprove “such fact” and that fact alone could be assessed.

The trial judge and the majority read the rule as authorizing an award to the successful litigant of all reasonable costs actually incurred in the preparation and conduct of the entire trial, because of a failure to prove a particular fact alleged. There *40is nothing in GCR 1963, 111.6 which compels that conclusion. The rule’s history and language are in opposition.

I would define unreasonable pleading as bad faith pleading, and bad faith pleading as allegation or denial of a fact known to be false at the time pleaded. I would permit assessment of reasonable expenses only to the extent incurred in “proving or preparing to prove or disprove such fact.” (Emphasis supplied.)

The problem of providing representation to a circuit judge unjustly charged, as in this case, deserves attention, but its solution should not be achieved by a sweeping interpretation of GCR 1963, 111.6 which will so importantly affect many other cases.

I respectfully find it necessary to dissent.
