Dеfendant appeals the trial court’s order granting plaintiffs’ motion for class certification. We affirm.
This is not the first time this matter has been before this Court. In a prior appeal, this Court set forth the background facts:
In the late 1950’s and early 1960’s, the City of Warren planted silver maple trees on public easements between the sidewalk and street curb in front of residents’ homes. In 1967, the city prohibited further planting of silver maples because they grow quickly and should have been planted away from structures and streets to avoid interferenсe with sewers and sidewalks. As the trees matured, their roots outgrew the space in which they were planted, and began to bore into the plaintiffs’ adjacent private property. The roots invaded and obstructed the sewer pipes which resulted in raw sewage and water backups into plaintiffs’ homes. The roots also grew upward and lifted the concrete sidewalk blocks which caused the sidewalk to be uneven and dangerous. The roots also destroyed the surface of plaintiffs’ lawns and killed grass and vegetation. Also, рlaintiffs spent a considerable amount of time and money for cleaning and repairs after their homes were flooded with raw sewage.
Because of certain provisions in the Warren Code, plaintiffs may not remove the silver maples and those residents who have tried to obtain a permit from the Director of Parks and Recreation to remove the trees have been repeatedly ignored or denied permission to do so. Defendant has not compensated plaintiffs for the damage caused by its trees, but has enacted various ordinances in order to help alleviate the problem. These measures include a cost-sharing plan for sidewalk replacement and the formation of a Sidewalk and Tree Board of Review. [Hill v City of Warren, unpublished opinion per curiam of the Court of Appeals, issued February 4, 2003 (Docket No. 229292).]
*303 Plaintiffs seek redress as a class encompassing all property owners in the city who are similarly affected. Defendant opposes class certification. Plaintiffs’ substantive claims include trespass-nuisancе, negligence, and governmental taking.
This litigation was commenced by Robert and Shirley Hill
1
in their individual capacities, and they filed an amended class action complaint shortly thereafter. The trial court originally denied their timely motion for class certification, concluding that the litigation would entail too much individualized fact-finding. Plaintiffs filed an application for leave to file an interlocutory appeal in this Court, in Docket No. 229292. This Court initially denied leave to appeal, but on reconsideration issued a peremptory order reversing the trial court and remanding the case for entry of an order granting class certification. Unpublished order of the Court of Appeals, entered January 29, 2001 (Docket No. 229292). Defendant sought leave to appeal in our Supreme Court, and our Supreme Court in an unpublished order, entered March 5, 2002 (Docket No. 118639), held that application in abeyance pending its decision in
Pohutski v City of Allen Park,
On remand, some additional discovery took place. Plaintiffs then filed a “renewеd motion for class certification.” The trial court observed that its initial denial had “always been a close decision,” and after “much careful consideration of the record and pleadings filed since the Court’s initial decision denying class certification,” it had become persuaded that class certification was the superior way for the action to proceed. It therefore granted class certification. Defendant applied for leave to appeal, which this Court denied for failure to persuade this Court of the need for immediate appellate review. Unpublished order of the Court of Appeals, entered April 11, 2005 (Docket No. 259706). Defendant then applied for leave to appeal in our Supreme Court, which, in lieu of granting leave to appeal, remanded the case to this Court for consideration as on leave granted. Our Supreme Court further directed us to
consider whether Pohutski v City of Allen Park,465 Mich 675 (2002), affects the class certification issue in this case. Pohutski held that § 7 of the governmental tort liability act, MCL 691.1407, does not permit a trespass-nuisance exception to governmental immunity, but rulеd that this holding would be applied only to cases brought on or after April 2, 2002. In light of Pohutski, are issues relating to putative plaintiffs unnamed as of April 2, 2002, sufficiently disparate from issues relating to plaintiffs who were named as of April 2, 2002, to the extent that certification of a single class containing both groups of plaintiffs would be inappropriate under MCR 3.501(A)(1)? [474 Mich 916 (2005).]
The matter is therefore now before this Court for consideration as on leave granted.
*305 Defendant first argues that the trial court was procedurally precluded from considering plaintiffs’ “rеnewed motion for class certification” by statute, case-law, or court rule. We disagree.
Interpretation of a statute is a question of law reviewed de novo on appeal.
Veenstra v Washtenaw Country Club,
Under MCR 3.501(B)(1), a plaintiff who files a complaint that includes class action allegations must move for class action certification within 91 days of filing the complaint, except by stipulation of the parties or on motion for good cause shown. If the plaintiff fails to do so, the class action allegations may be stricken unless the plaintiff shows excusable neglect. MCR 3.501(B)(2). “If certification is denied or revoked, the action shall continue by or against the named parties alone.” MCR 3.501(B)(3)(e). Defendant argues that even if plaintiffs could file a renewed motion after the remand order from our Supreme Court, plaintiffs would have been required to do so within 91 days thereof, which plaintiffs failed to do.
*306
There are no published cases in Michigan
2
substantively addressing the pertinent provisions of the court rule, or the amended version of the рredecessor rule, former GCR 1963, 208.2(A), which specified 90 days instead of 91 but was otherwise virtually identical to the current MCR 3.501(B)(1). The committee comments to Rule 208.2(A) indicate that the addition of a timing requirement was “designed to prevent cases from remaining pending for extended periods without the propriety of a class action being raised.” 1 Honigman & Hawkins, Michigan Court Rules Annotated (2d ed), 1984 pocket part, p 341. Furthermore, the court rules explicitly permit a trial court to
de
certify a class at any time after certification, and thus requires “that motions for decertification be treated as distinct and independent motions that implicate the same considerations as a motion to certify a class action, rather than as a motion for reconsideration.”
Tinman v Blue Cross & Blue Shield of Michigan,
Defendant next argues that plaintiffs’ renewed motion was really a motion for reconsideration that was
*307
impermissible because it was not made within the 14-day period permitted under MCR 2.119(F). Although the trial court treated the motion as one for reconsideration, plaintiffs did not present it as such. As a general matter, courts are permitted to revisit issues they previously decided, even if prеsented with a motion for reconsideration that offers nothing new to the court. MCR 2.119(F)(3);
Smith v Sinai Hosp of Detroit,
Defendant’s final procedural argument is that the “law of the case” doctrine precludes the trial court from reversing its initial denial of class certification, given that its denial had been affirmed by our Supreme Court. “The law of the case doctrine provides that if an
*308
appellate court has decided a legal issue and remanded the case for further proceedings, the legal issue determined by the appellate court will not be differently decided on a subsequent appeal in the same case where the facts remain materially the same.”
Grace v Grace,
Our Supreme Court’s holding was not, as defеndant asserts, that denial of class certification was
the correct result.
Rather, our Supreme Court held that the circuit court’s “denial of class certification was not clearly erroneous.” The clear error standard provides that factual findings are clearly erroneous where there is no evidentiary support for them or where there is supporting evidence but the reviewing court is nevertheless left with a definite and firm conviction that the trial court made a mistake.
A&M Supply Co v Microsoft Corp,
In other words, the clear error standard of rеview must, by definition, accommodate the possibility of multiple “right” results, or at least “permissible” results, similarly to the abuse of discretion standard. Underlying both standards is the possibility that the reviewing court could have reached a different result had it been in the shoes of the trial court, or that the reviewing court suspects an error occurred but lacks a sufficient basis to justify reversal. Again, our Supreme Court was not definitely and firmly convinced that the trial court made a mistake in denying class certification. That cannot be construed as a determination that the trial court would have made a mistake in
granting
class certification. The cases defendant cites in support of its position are all significantly distinguishable because they all entailed an
explicit, affirmative determination
of a point of law that was subsequently disregarded after a remand. We particularly note
Reeves v Cincinnati, Inc (After Remand),
Defendant argues that class certification was substantively improper. We disagree.
*310
A trial court’s ruling regarding certification of a class is reviewed for clear error, meaning that the ruling will be found clearly erroneous only where there is no evidence to support it or there is evidence but this Court is nevertheless “left with a definite and firm conviction that a mistake has been made.”
Zine v Chrysler Corp,
The first enumerated factor is numerosity. MCR 3.501(A)(1)(a). There is no particular number of members necessary, nor need the number be known with preсision “as long as general knowledge and common sense indicate that the class is large.” Zine, supra at 287-288. However, the class must be sufficiently well-defined and the members sufficiently well-identified that a reasonable estimate of the number of members can be determined. Id. Although plaintiffs’ assertion that there are some 7,000 “problem trees” is unlikely to be the precise number, and although we agree with defendant’s assertion that not every “problem tree” will necessarily equate to a class member, we find this factor amply satisfied. The newspаper articles submitted, as well as a letter from defendant’s officials and defendant’s decision to amend its ordinances apparently because of the tree problem, all support the conclusion that there are thousands of trees causing problems to homeowners’ properties. General knowledge and common sense likewise indicate that there are thousands of putative class members. Defendant contends that this *311 factor is unmet because the precise number should be easily ascеrtained. However, the precise number does not need to be ascertained. Furthermore, common sense and general knowledge indicate that, out of thousands of homes in a residential area, there might be a certain amount of turnover in home ownership. Joinder of the homeowners as individuals would therefore likely necessitate regularly moving plaintiffs in and out of the case, so identifying them with precision may not be as simple and straightforward as defendant suggests.
The second factor, and the most significant to this litigation, is whether there exists a common question of fact or law that applies to the entire class, the resolution of which as a general issue will advance the litigation. MCR 3.501(A)(1)(b); Zine, supra at 289; A&M Supply Co, supra at 599. This factor does not require all issues in the litigation to be common; it merely requires the common issue or issues to predominate over those that require individualized proof. Id. This also relates to “the fifth factor in that if individual questions of fact predominate over common questions, the case will be unmanageable as a class action.” Zine, supra at 289 n 14. The parties agree that a common questiоn of defendant’s liability exists and that individualized questions of how much damage each class member has suffered exist. The question before us is whether the trial court clearly erred in concluding that the predominating issue or issues to be resolved in the litigation are generalized and common to the class. We conclude that it did not.
Defendant asserts that the homeowners have sustained a wide variety of damages ranging from raw sewage flooding their basements, to cracked sidewalks, to unattractive lawns; moreover, the homeowners have likеly undertaken a wide variety of prophylactic or *312 corrective actions. Defendant also notes that each homeowner would need to prove that any damage actually came from trees planted by the city on the public easement in front of the homeowner’s property. Defendant therefore contends that class certification would be unwarranted because this matter would degenerate into a procession of “mini-trials.” However, plaintiffs have presented photograрhs and deposition testimony from defendant’s then-current director of parks and recreation 3 indicating that establishing whether any homeowner had suffered damages from city-planted trees is likely to be simple and easy. Plaintiffs have also provided a list of bills from plumbers indicating that sewer lines were plugged with roots. Most individualized fact-finding would concern the amount of damage, not the existence of damage. The amount of damage need not be uniform as long as the trial court has some basis for concluding “that all members of the class had a common injury that could be demonstrated with generalized proof, rather than evidence unique to each class member.” A&M Supply Co, supra at 600.
The individualized determinations of the extent of damage will not predominate over the common question whether defendant is liable at all for damage caused by its trees. We further note that defendant’s letter to homeowners, signed by defendant’s service division administrator and apparently drafted by defendant’s deputy mayor, which discusses “[t]he dreaded property maintenance ordinance” and the fact that trees planted by prior city administrations wеre destroying sidewalks, implies that defendant itself recognizes that its liability is a predominating common issue. *313 We find no clear error in the trial court’s determination that the predominant issues were generalized, not individual.
Under the third factor, “the claims or defenses of the representative parties [must be] typical of the claims or defenses of the class.” MCR 3.501(A)(1)(c);
A&M Supply Co, supra
at 601. Factual differences between the class members’ claims are not inherently fatal to certification, but their claims must share a legal theory and “ ‘ “core оf allegation.” ’ ”
Neal v James,
*314
The final factor asks “whether a class action, rather than individual suits, will be the most convenient way to decide the legal questions presented, making a class action a superior form of action,” the primary concern being that of practicality and manageability.
A&M Supply Co, supra
at 601; MCR 3.501(A)(1)(e). Under MCR 3.501(A)(2), the trial court is explicitly required to consider a number of subfactors in making its dеtermination regarding the fifth factor. Our Supreme Court has explained that this fifth factor is “essentially the same” as the “convenient administration of justice” consideration required under former GCR 1963, 208, and it is essentially a practicality test.
Dix v American Bankers Life Assurance Co of Florida,
Defendant further argues that, even if this matter proceeds as a class action, plaintiffs’ trespass-nuisance claims remain unavailable to any parties not explicitly named as plaintiffs as of April 2, 2002, when our Supreme Court decided
Pohutski.
We disagree. Defendant relies on
Lessard v City of Allen Park,
Finally, defendant argues that the unnamed class members face individualized questions pertaining to the applicable statutes of limitations. Although any statutory period of limitations is tolled with regard to described class members upon the filing of a class action complaint, MCR 3.501(F)(1), the period resumes running “on entry of an order denying certification of the action as a class action.” MCR 3.501(F)(2)(c). However, “[i]f the circumstance that brought about the resumption of the running of the statute is superseded by a further order of the trial court. .. the statute of limitations shall be deemed to have been tolled continuously from the commencement of the action.” MCR 3.501(F)(3).
In
Cowles v Bank West,
Here, there has been no change in the claims or the “generic identities of the potential plaintiffs.” And significantly, the trial court’s conclusion that its earlier denial of class certification had been incorrect superseded the “circumstance that brought about the resumption of the running of the statute.” Therefore, there is no limitations period on the unnamed class members’ becoming part of the litigation. Furthermore, our Supreme Court’s discussion of the policies in Cowles supports the conclusion that Pohutski is intended to apply to cases rather than to parties: as long as defendant was generally aware of the claims and parties it would face, the fact that the parties were not explicitly named should not be an impediment to their joining a pending class action suit in the future.
*317 In summary, we find no procedural or legal impediment to the trial court’s revisiting its earlier denial of class certification. We also find no clear error in the trial court’s finding that class certification is appropriate. Finally, we find no procedurаl or legal impediment to extending class membership with regard to all claims in this matter to class members who were not explicitly named in the initial complaint or as of April 2, 2002.
Affirmed.
Notes
Because they subsequently sold their home in Warren, they are no longer parties to this suit.
Federal Rule of Civil Procedure 23 has no similar time limitations, likely making any federal precedent inapplicable. See
Tinman v Blue Cross & Blue Shield of Michigan,
The director is the person who, by operation of defendant’s ordinances, has complete and exclusive control over trees in front of residences, including whether to permit their removal. Warren Ordinances §§ 38-2, 38-13.
