On June 27, 1972, the city notified Kalikow Realty Company (Kalikow) that a defect in the sidewalk abutting its premises needed repair. Kalikow responded by letter indicating that the sidewalk had been repaired, and that Kalikow would maintain the sidewalk in a safe condition until its construction of the premises was complete. Approximately two years later, while the premises were still under construction, a pedestrian was injured as a result of a defect in the sidewalk abutting Kalikow’s premises. The pedestrian sued the city and the contractor for negligence. Kalikow was neither sued nor impleaded by the city. The jury verdict and $95,486.46 judgment were against the city only. After satisfying the judgment, the city, in a separate action, sought indemnification from Kalikow. Special Term granted summary judgment in favor of the city.
Initially, the instant case should be distinguished from those cases in which indemnification is granted as against an impleaded third-party defendant. Impleader permits, and, in fact, encourages a third-party defendant to defend the main action himself; the third-party defendant "stands in the shoes” of the defendant and may assert any defenses the defendant may have against the plaintiffs main claim. (See, CPLR 1008; Phillips v Chevrolet Tonawanda Div., 43 AD2d 891, 892 [4th Dept 1974].) Impleader implicitly acknowledges that if a defendant is reasonably certain of receiving an indemnity judgment over, his defense of the main action may be less than zealous. (Siegel, NY Prac § 163, at 204.)
Here, Kalikow was never made a party to the underlying personal injury action and was never afforded the opportunity it would have had as an impleaded third-party defendant to controvert the claims asserted by the plaintiff therein. (Contrast, Burke v City of New York, 2 NY2d 90 [1956], and Rogers v Dorchester Assocs., 32 NY2d 553 [1973] [where the proposed indemnitors were joined in the main action].) While this does not prevent the city from seeking indemnity in a separate action, it leaves unanswered the question of whether the city adequately defended against the judgment upon which the present derivative claim is based. Certainly, a cause for indemnification is deprived of its equitable underpinnings when it is unsupported by a showing that the main action was *485properly defended. I do not think it can be said that the city has made such a showing in this case.
The record contains only minor excerpts from the trial transcripts and a conclusory affidavit in which counsel for a city departmental agency attests to the competency of the city’s defense; counsel’s opinion is based primarily upon the city trial attorney’s experience and reputation and the fact that the money judgment was less than the amount the injured party sought in the complaint. I cannot agree that this is a sufficient basis to establish the adequacy of the city’s performance. At a minimum, the record should contain a transcript of the proceedings in which the underlying liability determination was rendered so that an independent judgment can be made as to whether the damages awarded were a fair reflection of the plaintiff’s injuries and whether, upon the entire record, the city’s conduct of the defense was as vigorous as it would have been had the prospect of indemnification not existed. Absent such a showing, I do not think the city has made out a prima facie case for indemnification. At best, the city’s showing leaves an open factual issue respecting its advocacy as a defendant in the personal injury action, barring summary disposition of the case. (See, Rotuba Extruders v Ceppos, 46 NY2d 223 [1978].)
Moreover, in my view, the application of the doctrine of implied indemnity in the circumstances here obtaining is inappropriate. While there is, arguably, some basis in precedent for so employing the doctrine, resort to its use should be tempered by careful consideration of its underlying rationale and the policy consequences resulting from its application.
The city has been directed by the Legislature to maintain its sidewalks in good condition. This duty is nondelegable. If the duty may not be delegated, neither may liability for its nonperformance be effectively shifted to another.
While section 230 of the New York City Charter requires a property owner to "install, reconstruct, repave and repair the sidewalk in front of or abutting such property”, it also provides that "[a]ll such work shall be done * * * in accordance with such specifications and regulations as may be prescribed by the transportation administration”. It is the administration’s duty to determine "[w]henever * * * a sidewalk should be * * * repaired”. It is additionally the administration’s duty to cure a defect left unremedied by a property owner who has been put on notice and, thereafter, to charge the owner for the repair. Clearly, section 230 does not shift the responsibility of maintaining and repairing public sidewalks to the *486abutting landowner. Indeed, the cases hold that a statutory provision such as section 230 of the New York City Charter is "merely regulatory in nature and does not impose tort liability upon an abutting owner” (Jacques v Maratskey, 41 AD2d 883 [3d Dept 1973]; see, City of Rochester v Campbell, 123 NY 405 [1890]).
The Legislature clearly intended that the city would remain primarily responsible for maintaining its streets in good condition, and indeed, there is no reason to effectively shift the responsibility by employing the doctrine of implied indemnity. The city is plainly capable of maintaining its sidewalks. In this respect it is to be contrasted with the building owner in Rogers v Dorchester Assocs. (supra, at 561), who was "ill-equipped to service the complicated, delicate, and potentially dangerous elevator apparatus.” (See also, supra, at 566.) Under the circumstances in Rogers, where there was no option but to delegate the duty imposed by statute, indemnification was appropriate because the owner’s liability was truly vicarious. The city’s liability in the present case, however, reflects its actual failure to do what it could have and should have done to avoid the complained-of harm.
As was ably stated by Justice Eder in his concurrence in Burke v City of New York (supra, at 95-96), " 'Implied indemnity’ is a doctrine 'based upon principles of equity’ (Trustees of Geneva v. Brush Elec. Co., 50 Hun 581, 584) evolved by the courts to ameliorate in exceptional circumstances 'the rigor of the rule which forbids recourse between wrongdoers.’ (Washington Gas Light Co. v. District of Columbia, 161 U. S. 316, 327.) It is applied only in situations where the relationship between joint tort-feasors to one another or to the event indicates such a difference in their respective delinquencies that one may be said to be actually or primarily, and the other only legally or secondarily, responsible for the happening of the consequent damages.” Classic common-law indemnification situations concern vicariously liable tort-feasors and tort-feasors guilty of the acts or omissions causing harm: e.g., master and servant; employer and negligent employee; automobile owner and negligent driver; building owner and independent contractor exclusively responsible for maintenance of the building or parts thereof (as in Rogers v Dorchester Assocs., supra). In time, the doctrine of implied indemnification was broadened so that "one who was cast in damages for negligence could, if his negligence were merely 'passive’, nevertheless shift his liability to the tort-feasor whose negligence was considered 'active’.” (D’Ambrosio v City of New *487York, 55 NY2d 454, 461 [1982]; see, e.g., Burke v City of New York, supra; and, e.g., City of Brooklyn v Brooklyn City R. R. Co., 47 NY 475, 478 [1872].)
The necessity of applying the active/passive criteria in indemnification situations has been largely eliminated by Dole v Dow Chem. Co. (30 NY2d 143 [1972]), which permits the very recourse between wrongdoers, the absence of which was formerly ameliorated by application of the doctrine of implied indemnity. "Dole rejected the unpredictable result of attempting to shift entire liability based upon the theory of whose negligence was greater, and adopted the more realistic approach of holding joint tort-feasors liable according to their respective degrees of fault.” (D’Ambrosio v City of New York, supra, at 462.) The Dole rule was not intended to overturn basic and satisfactory principles of common-law indemnification, but was instituted to address those situations where tortfeasors shared responsibility for causing the harm. (See, Rogers v Dorchester Assocs., supra, at 565-566.)
Where, as here, the Legislature has placed with the city the duty of protecting the public from defective sidewalks and streets and the city is clearly capable of meeting the obligation (cf., Rogers v Dorchester Assocs., supra), there is no reason in law or policy why the city should not bear the consequences of negligently entrusting its duty to Kalikow. As the city’s actual fault is the predicate for its liability, it must share responsibility with Kalikow for the resulting harm. (Cf., D’Ambrosio v City of New York, supra.)
The natural consequence of the majority’s decision is, I think, most unfortunate, for it tends to provide municipal corporations with a means to avoid the performance of their duties respecting the repair and maintenance of sidewalks and streets. I very much doubt that the equitable doctrine of implied indemnity was intended to so facilitate the transfer of a statutorily imposed nondelegable public obligation. Indeed, given the position the majority now takes, I can see no obstacle to the routine issuance of letters to property owners offering forebear anee by the city in exchange for the owner’s promise to maintain the abutting sidewalk in good condition. Upon the owner’s assent to this attractive proposition, the city would in effect avoid its supposedly nondelegable duty, as it would be assured of complete and summary relief from the consequences of its negligence.
Accordingly, I dissent and would reverse to the extent of denying the city’s motion for summary judgment and remanding for further proceedings.
