R. B. Burns, P. J.

Plaintiff, a citizen "environmentalist” organization, sued in equity to rescind the sale of "excess land” by defendant highway department to defendant Northern Michigan Inns. Defendants prevailed on the merits via summary judgment. Northern Michigan Inns then filed a motion for taxation of costs and for leave to pay and tax more than the ordinary fees for expert testimony (totaling $3,640.18). Plaintiff appeals the *387trial court’s grant of this motion, and appeals the court’s denial of plaintiffs similar motion.

Plaintiff and the Amici Curiae urge an omnibus treatment of the issues raised on appeal; we are requested to aid in "developing a common law of environmental quality”, to avoid a "chilling impact on citizen-initiated environmental litigation in Michigan”, to "establish general standards or guidelines for the apportioning of costs in environmental lawsuits”. Defendants, in turn, urge a simple affirmance.

The authority for an award of fees and costs, including taxable attorney fees and reasonable expert witness fees, is statutory. MCLA 600.2405; MSA 27A.2405, MCLA 600.2164; MSA 27A.2164. It is denoted in MCLA 600.2401; MSA 27.2401 that "[e]xcept as otherwise provided by statute, the supreme court shall by rule regulate the taxation of costs”. The controlling court rule is GCR 1963, 526.1:

"In any action or proceeding, costs shall be allowed as of course to the prevailing party, except when express provision therefor is made either in a statute or in these Rules, or unless the court otherwise directs, for reasons stated in writing and filed in the cause.” (Emphasis added.)

Falling within the "except when express provision * * * in a statute” supervention is the appropriate section of the Environmental Protection Act (EPA), MCLA 691.1203(3); MSA 14.528(203X3): "Costs may be apportioned to the parties if the interests of justice require.” (Emphasis added.)

Construed in concert, as they must be, these provisions yield one indisputable principle: the award of costs and fees in cases such as this is within the broad and unfettered discretion of the *388trial judge, a discretion that must, however, be recognized and exercised. We only look to see if such discretion has been exercised, and, if so, abused.

The trial court’s opinion on defendant Northern Michigan Inn’s motion reveals his mistaken belief that he had "a very limited area of discretion”; the court seems to consider the "prevailing party” language of GCR 1963, 526.1 to rise nearly to the authority of an order. Further, it appears that the court was unaware of the permissive apportionment provision of MCLA 691.1203(3); MSA 14.528(203X3). We must, therefore, remand for a reevaluation of the respective parties’ motions for costs and fees by a valid exercise of the trial judge’s previously unrecognized discretion.

However, we do not mean to imply a result. In this regard, plaintiffs contention that apportionment of fees is "mandated” by the EPA is clearly wrong. The trial judge must reach the result that "the interests of justice require”. He may agree with Amici Curiae that apportionment is an appropriate remuneration for a plaintiff that has borne the expense of performing "a valuable public service” by airing "important public issues”; he may agree with defendants concerning the often great expense necessary to "defend against unwarranted allegations”.

It is not necessary or appropriate for this Court to lay down "rules” regarding "private attorneys general”. We similarly reject as undesirable the concept that we must articulate "guidelines and principles” to structure the traditional flexibility of the exercise of equitable discretion. The trial judge gets sufficient guidance from the statutory directive that he serve "the interests of justice”. Determinations as to fee and cost awards must of *389necessity be made through full consideration of the unique facts presented in each individual case. Again, our role is limited to a review to determine a possible abuse of that discretion.

One more point needs to be covered. Plaintiff argues in the alternative that no costs should have been awarded because a "public question” was involved. While it has been the frequent and traditional policy of our appellate courts to deny costs in "public question” cases, we specifically disavow the pronouncement of City of Berkley v Holmes, 34 Mich App 417, 429; 191 NW2d 561 (1971), that any such award constitutes "an abuse of discretion”. Our policy is wholly superseded by MCLA 691.1203(3); .MSA 14.528(203X3) for suits brought under the EPA; suits that, incidentally, inevitably involve public questions.

The cause is remanded. Costs to abide final results.
