D'AGOSTINI
v.
CITY OF ROSEVILLE
Docket No. 56395, (Calendar No. 5).
Supreme Court of Michigan.
Argued October 9, 1975.
Decided April 1, 1976.
Joseph P. Puzzuoli and Felice V. Iafrate for plaintiff.
Wenger, Vande Vrede & Lavigne, P.C., for intervening defendants.
LINDEMER, J.
Plaintiff owns two adjacent parcels of land within the City of Roseville. He petitioned the Roseville Planning Commission to rezone his property from single-family residential to multi-family residential. His petition was denied on March 19, 1973. Plaintiff then sought to obtain rezoning from the city council, but on April 24th, it voted to deny his request. Finally plaintiff commenced *187 this lawsuit in Macomb Circuit Court, seeking to enjoin the City of Roseville from interfering with plaintiff's proposed use of his property. On December 17, 1973, appellants, neighboring property owners situated within 300 feet of the subject property, filed a petition to intervene as of right, pursuant to GCR 1963, 209.1(3). The trial court denied intervention on February 28, 1974, upon the ground that appellants failed to meet the requirement of the court rule, and the Court of Appeals denied review. This Court granted the application for leave to appeal in order to consider the propriety of the trial court's action. We find the trial court to be in error and reverse.
GCR 1963, 209.1(3) reads:
".1 Intervention of Right. Anyone shall be permitted to intervene in an action
* * *
"(3) upon timely application when the representation of the applicant's interest by existing parties is or may be inadequate and the applicant may be bound by a judgment in the action".
The primary source of this rule was Rule 24 of the Federal Rules of Civil Procedure. At the time of the adoption of GCR 1963, 209.1(3) the parallel Federal rule, FR Civ P, 24(a)(2) read:[1]
"Upon timely application anyone shall be permitted to intervene in an action * * * when the representation of the applicant's interest by existing parties is or may *188 be inadequate and the applicant is or may be bound by a judgment in the action."
Because of the similarity of the state and Federal provisions we deem it proper to look to the Federal courts for guidance.
GCR 1963, 209.1(3) requires three elements:
a. Timely application;
b. Representation of the applicant's interest by existing parties is or may be inadequate;
c. Applicant may be bound by a judgment in the action.
All of the above must be present in order for the applicant to qualify for intervention of right, and we believe they are.
a. Timely application.
It is a general rule that a right to intervene should be asserted within a reasonable time. Laches or unreasonable delay by the intervenors is a proper reason to deny intervention. For general statements of the law see School District of the City of Ferndale v Royal Oak Township School District No 8, 293 Mich 1; 291 NW 199 (1940) (applying prior Michigan law). 59 Am Jur 2d, Parties, §§ 161, et seq., pp 593, et seq.
In this case there were no allegations of unreasonable delay and we find no basis in the record for denying intervention on this ground.
b. Representation of the applicant's interest by existing parties is or may be inadequate.
When deciding to deny intervention the trial judge held that GCR 1963, 209.1(3) "requires first inadequacy of representation, and secondly distinction of issues between themselves and that of the principal defendant".
This statement is in error. The intervenor satisfies the requirements of the court rule by establishing that his representation is or may be inadequate. *189 Significantly, the United States Supreme Court has remarked:
"The requirement of the Rule is satisfied if the applicant shows that representation of his interest `may be' inadequate; and the burden of making that showing should be treated as minimal. See 3B Moore, Federal Practice, § 24.09-1[4] (1969)." Trbovich v United Mine Workers of America, 404 US 528, 538, fn 10; 92 S Ct 630; 30 L Ed 2d 686 (1972).
The State of Illinois has a statute which closely parallels the language of our court rule. In Bredberg v City of Wheaton, 24 Ill 2d 612; 182 NE2d 742 (1962), the Illinois Supreme Court stated sound reasons why adjacent landowners should be permitted intervention into a zoning case.
"Statutes providing for intervention are remedial and are liberally construed. And, as was stated by the Joint Committee who drafted our act: `Intervention is frequently desirable to allow a person to protect an interest jeopardized by pending litigation to which he is not a party or to avoid relitigation in another suit of issues which are being litigated in a pending suit.' This language has singular application here where the Bredbergs, as owners of immediately adjoining property, were possessed of rights which would be adversely affected by the granting of the counterclaim, and whose interest in the ligitation [sic] far exceeded that of the general public or other owners in the area. Moreover, we may consider that the city, the only defendant named in the counterclaim, is primarily concerned with the city-wide zoning pattern and cannot be guided solely by a consideration of individual hardships. Under such circumstances the legitimate objects and purposes of the city could well result in compromises to the detriment of individual rights such as those of the Bredbergs. Indeed, demonstrative in this case is the fact that the city of Wheaton has taken no appeal from the judgment finding its ordinance invalid in its application *190 to a portion of the Booth property." Bredberg, supra, 623-624. (Citations omitted.)
We agree with these reasons and find that the intervenors in this suit have met the second requirement.
c. Applicant may be bound by a judgment in the action.
We recognize a split in authority has developed over the interpretation of the word "bound". Courts are divided over whether "bound" should be read in the narrow legal sense that the petitioner must be bound under the principles of res judicata or whether the term should be read in the broader sense that, as a practical matter, the petitioner's ability to protect his interest would be substantially affected. Plaintiff urges that we adopt res judicata as our standard. He contends that under a res judicata approach the intervenors would not be bound and therefore they should not be allowed to intervene as of right. However, we believe there are strong policy reasons to adopt a broader reading of the court rule. The express use of the words "may be" in the rule, read in the context of its purpose, demonstrates that a mere possibility that the judgment will be binding is sufficient to permit intervention.
Additionally, a res judicata construction of GCR 209.1(3) poses a serious dilemma, by which it might prove impossible for an absent party to qualify for intervention.
"If the representation of an absent party is inadequate, he cannot be bound by the judgment in the action, and thus cannot intervene, while if the representation is adequate, he does not meet the second half of the test of Rule 24(a)(2) and still cannot intervene." 2 Barron and Holtzoff, Federal Practice and Procedure (Cum Supp 1970), § 597, p 135. (Footnotes omitted.) *191 The Court of Appeals faced this problem in Davidson v City of Pontiac, 16 Mich App 110, 118; 167 NW2d 856 (1969).
"To avoid this dilemma something less than res judicata should be required before it can be said that the applicant may be `bound.' It was noted in the Advisory Committee's Notes to amended Rule No 24, Federal Rules of Civil Procedure that `the deletion of the "bound" language * * * frees the rule from undue preoccupation with strict considerations of res judicata.' Avoiding this preoccupation, in what sense might the appellant be `bound' by the adjudication of this matter? The injunction sought here will prejudice his exercise of the right to petition unless he can secure dissolution of the injunction by collateral attack."
We agree with the Court of Appeals that the broader standard should apply. Under that standard intervenors satisfy the final element of the court rule.
Reversed and remanded to the trial court. No costs, a public question being involved.

NOTES
[1]  FR Civ P, 24(a)(2) was amended, eff. July 1, 1966, to read: "when the applicant claims an interest relating to the property or transaction which is the subject of the action and he is so situated that the disposition of the action may as a practical matter impair or impede his ability to protect that interest, unless the applicant's interest is adequately represented by existing parties".
