The present litigation arose out of a complaint filed with defendant Department of Civil Rights in 1976. Eventually plaintiff brought this suit seeking an order for superintending control. The circuit court issued an order of superintending control on June 4, 1980, and defendant appeals as of right.
On March 1, 1976, Ludy Crain filed a charge of unlawful discrimination against plaintiff with defendant. Defendant issued a charge against plaintiff based on this complaint on July 24, 1978, and subsequently filed an amended charge on October 16, 1979, seeking $20,000 in damages for emotional distress.
In the meantime defendant held public hearings in connection with the enactment of a rule concerning depositions in its adjudicatory hearings. Eventually it issued rule 37.15, which was promulgated on October 2, 1979, and which took effect October 17, 1979. The rule states:
"Rule 15. In accordance with the Michigan general court rules, the commission or any member thereof, or the director, on its own motion or on the application of 1 of the parties, may take or cause to be taken depositions of witnesses residing within or without the state.” 1979 AC, R 37.15.
*100Before 1977, GCR 1963, 302.1 read:
"After commencement of an action, any party may take the testimony of any person, including a party, by deposition upon oral examination or written interrogatories for the purpose of discovery or for use as evidence in the action or for both purposes. In all actions pending before any probate court, commissioner of claims appointed by a probate court, arbitrator, referee, circuit court commissioner, justice of the peace, or other court not expressly covered by these rules or before any administrative agency in the exercise of judicial functions, depositions may be taken and used in accordance with these rules for use as evidence only and not for the purposes of discovery and only admissible evidence shall be taken.”
However, this court rule was amended effective March 3, 1977. It now states:
".1 When Depositions May Be Taken. After commencement of an action in any court, any party may take the testimony of any person, including a party, by deposition on oral examination or written interrogatories for the purpose of discovery or for use as evidence in the action or for both purposes.”
After receiving the amended complaint, plaintiff issued a notice of deposition. In response, defendant issued a final order stating that pursuant to rule 37.15 it would not allow plaintiff to depose Mr. Crain because plaintiff intended a discovery deposition and not an evidentiary deposition. In its ruling, defendant explained that it had been unaware of the change in GCR 1963, 302.1 and therefore never intended to incorporate the amended rule. Defendant also ruled that, in any event, rule 37.15 gave the commission discretion to deny discovery depositions.
On February 6, 1980, plaintiff brought suit in *101Ingham County Circuit Court asking for a declaratory judgment, or, in the alternative, an order for superintending control. Both parties soon filed motions for summary judgment. On April 9, 1980, in a hearing before the trial court, plaintiffs motion was granted. An order of superintending control was issued on June 4, 1980, and defendant appeals.
Defendant raises two issues on appeal. First, defendant contends that an order of superintending control should not have been issued inasmuch as the Administrative Procedures Act allows a plaintiff to test administrative rules through a declaratory judgment. MCL 24.264; MSÁ 3.560(164). This is a case of first impression under the Michigan Administrative Procedures Act.
The general guidelines for an order of superintending control were enunciated in People v Flint Municipal Judge, 383 Mich 429, 431; 175 NW2d 750 (1970): "the proper office of superintending control [is to review] the discretion of an examining magistrate. * * * Superintending control, like mandamus, lies to require the magistrate to perform a function where the magistrate has a clear legal duty to act.” This order may be used to review administrative procedures. Gerber Products Co v Anderson, Clayton & Co, 76 Mich App 410; 256 NW2d 754 (1977). However:
"The superintending court does not substitute its judgment or discretion for that of the magistrate; neither does it act directly in the premises. Rather it examines the record made before the magistrate to determine whether there was such an abuse of discretion as would amount to a failure to perform a clear legal duty; and in such case, the superintending court orders the magistrate to perform his duty.” People v Flint Municipal Judge, supra, 432.
*102Basically the grant or denial of such an order is within the discretion of the trial court and the Court of Appeals on review will disturb it only if there is an abuse of discretion. Attorney General v Recorders Court Judge, 92 Mich App 42; 285 NW2d 53 (1979).
However, the order of superintending control is governed by GCR 1963, 711:
".2 Policy Concerning Use. If another adequate remedy is available to the party seeking the order, a complaint for superintending control may not be filed.
".4 Jurisdiction.
"(b) When an appeal in the Supreme Court, the Court of Appeals, or the circuit court is available, that method of review must be used. If superintending control is sought and an appeal is available, the complaint for superintending control must be dismissed.”
In other words, the circuit court properly exercises superintending control over inferior tribunals only if another plain, speedy, and adequate remedy is not available. Farmers State Bank of Concord v Dep’t of Commerce, Financial Institutions Bureau, 77 Mich App 313; 258 NW2d 496 (1977). However, superintending control does not supersede the use of normal appellate procedure when such an appeal would be available and adequate for that purpose. Radke v Employment Security Comm, 37 Mich App 104; 194 NW2d 395 (1971).
In this case, in our opinion, the trial judge abused his discretion in ordering superintending control because a declaratory judgment could have been used to adequately safeguard plaintiffs interests. Yet, in so ruling, we express no disagreement *103with Chrysler Corp v Civil Rights Comm, 68 Mich App 283, 289; 242 NW2d 556 (1976):
"We do not read GCR 1963, 711.2 as requiring a judicial 'hands off policy towards an administrative tribunal acting without authority. * * * It only requires consideration of other avenues of review open to the party requesting an order of superintending control.”
Chrysler is distinguishable from the present case because it did not present the issue of a declaratory judgment. Instead the Court ruled that the Civil Rights Commission had erred in ruling on the preliminary question of its power to act upon complaints filed under the 90-day limitation period. Because this ruling came two-and-one-half years after plaintiff had raised the question by its motion to dismiss, the normal review processes were inadequate.. On the other hand, in the present case, plaintiff brought the suit for an order of superintending control as an alternative to an order for a declaratory judgment. Such an order would have been just as quick as. an order for superintending control.
Defendant cites Cahill v 15th Dist Judge, 393 Mich 137; 224 NW2d 24 (1974), in support of its position. However, Cahill is distinguishable because there the plaintiff had alleged that he properly represented a class of similarly situated persons. Therefore the Supreme Court allowed superintending control because he was challenging general practices and was claiming for a class of persons. Recently, a case closer to plaintiff’s position was decided. In In re Smith, 106 Mich App 621; 308 NW2d 586 (1981), this Court ruled that an order of superintending control did properly issue where the defendant had been improperly denied a court reporter even when demanded. *104Even though the plaintiffs did not allege a general practice or a class action, it was noted that the courts would be burdened by requiring each victimized plaintiff to appeal his own case (especially where such a clear right is involved). However, in this case, the right is not so clear (as will be developed later in this opinion) and plaintiff has an additional remedy unavailable to the litigants in either Smith or Cahill: the declaratory judgment provision of the Administrative Procedures Act. Through this provision, plaintiff can just as easily bind defendant in not only the Ludy Crain matter but also in future matters (in fact, for other similarly situated litigants as well); thus the courts are just as easily relieved of the time-wasting case-by-case appeal process rejected in Smith.
Therefore, we remand this case back to the circuit court with instructions to end the order of superintending control. Since the question of the regulation’s interpretation will be raised again on remand, it is necessary to address it at this time.
We have concluded that the trial court did not err in its interpretation of rule 37.15. In our view, full discovery is a benefit to the truth-seeking function of any tribunal. Consequently, we believe that any administrative rule which seeks to restrict discovery should be critically examined.
In this case, the applicable rule, 37.15, merely states that depositions may be granted. The rule does not distinguish evidentiary and discovery depositions. As such, we feel that under iule 37.15 a litigant has a right to expect serious consideration by the Michigan Civil Rights Commission of whether discovery depositions are really needed in the cause. Where a rule authorizes the commission to exercise its discretion, it is not enough for it to say that the commission always exercises its dis*105cretion to prohibit the action in issue. Compare, Cleveland-Cliffs Iron Co v First State Ins Co, 105 Mich App 487, 497; 307 NW2d 78 (1981), Croda v Sarnacki, 106 Mich App 51; 307 NW2d 728 (1981) (Bronson, J., dissenting).
We agree with Judge Maher that, where an ambiguity appears in an administrative rule, the agency’s interpretation is extremely persuasive. However, we find no ambiguity in rule 37.15. We acknowledge that OCR 1963, 302.1 was amended in 1977 and that this change in the rules was supposedly unknown by the commission before it promulgated rule 37.15. However, since rule 37.15 actually took effect in October, 1979, some two- and-one-half years after the relevant amendment to GCR 1963, 302.1, we cannot accept defendant’s argument that the commission never really intended to allow discovery depositions. We see only inherent unfairness to the litigant who relies on the literal language of an administrative rule when the agency which has promulgated that rule subsequently attempts to rewrite it under the guise of "interpretation” because it was negligent in enacting a rule which really did not embody its desires in the first place. In such situations, the administrative agency, not the litigant, should suffer the consequences of its negligence.
Reversed and remanded for further proceedings in accordance with this opinion. We retain no jurisdiction. No costs, neither party having prevailed in full.
