*390Section 17 of the Zoning Act, G. L. c. 40A, sets out the procedural requirements for a person aggrieved by a decision of a zoning board of appeals or special permit granting authority to seek judicial review "by bringing an action within twenty days after the decision has been filed in the office of the town clerk," and further specifies *752that "[n]otice of the action with a copy of the complaint shall be given to such city or town clerk so as to be received within such twenty days." A judge of the Land Court allowed the defendant's motion for summary judgment, dismissing the plaintiffs' complaint, on the ground that the plaintiffs did not timely give the required notice to the town clerk. Because the undisputed facts in the summary judgment record establish that *391the town's assistant clerk had actual knowledge of the plaintiffs' complaint within the required time, we reverse the judgment. See Konover Mgmt. Corp. v. Planning Bd. of Auburn, 32 Mass. App. Ct. 319, 324-325, 588 N.E.2d 1365 (1992) ( Konover ).

Background. The following facts are established by the summary judgment record. The plaintiffs, Brian S. Hickey and Mary P. Hickey own land abutting the location of a proposed stairway leading to Cape Cod Bay. The Dennis building commissioner determined that the stairway would be a landscape feature not subject to the setback requirements set forth in the local zoning by-law, and not requiring a building permit.

The Hickeys unsuccessfully appealed from that decision to the defendant zoning board of appeals of Dennis (board). After voting unanimously to uphold the building commissioner's determination, the board filed its decision with the town clerk's office on April 14, 2016.

On April 20, 2016, the Hickeys timely filed their complaint appealing from the board's decision in the Land Court under G. L. c. 40A, § 17. On April 21, 2016, the Hickeys' counsel sent copies of the complaint by certified mail to each of the individual members of the board, addressed to their respective homes.2 On the same day, the Hickeys' counsel sent a package by certified mail addressed to "Chairman, Zoning Board of Appeals" at the Dennis town hall, which included copies of the same documents sent to the board members individually.

The chairman's packet was received at the Dennis town hall on April 25, 2016, where it was routed to the office of the town planner by some time on April 26, 2016. After his receipt of the chairman's packet, the town planner had a series of conversations with the assistant town clerk. At some point prior to May 4, 2016 (the end of the twenty day appeal period), the town planner told the assistant town clerk that the plaintiffs had filed their complaint in the present case in the Land Court.3 It is, in other words, undisputed that the assistant town clerk had actual knowledge that the plaintiffs had appealed from the board's decision before the *392appeal period expired.4

It is undisputed that the Hickeys' counsel did not mail a copy of the complaint to the Dennis town clerk. Moreover, neither *753the clerk nor the assistant clerk saw a copy of the Hickeys' complaint before May 5, 2016. The Hickeys' counsel's only direct communication with the town clerk's office for the purpose of providing notice of the appeal occurred by an electronic mail message dated May 5, 2016-which he sent after the town clerk certified that she had not received any notice of an appeal within the required timeframe.5

The board moved to dismiss the Hickeys' complaint, based on the failure to file notice of the appeal or a copy of the complaint with the town clerk before May 4, 2016. After the Land Court judge permitted limited discovery on the issue, the board converted its motion to one for summary judgment. The judge then allowed the motion, and entered judgment dismissing the complaint. This appeal followed.

Discussion. "[R]eceipt of notice by the town clerk is a jurisdictional prerequisite for an action under G. L. c. 40A, § 17, which the courts have 'policed in the strongest way' and given 'strict enforcement.' " See Konover, 32 Mass. App. Ct. at 322-323, 588 N.E.2d 1365, quoting from Pierce v. Board of Appeals of Carver, 369 Mass. 804, 808, 343 N.E.2d 412 (1976) and O'Blenes v. Zoning Bd. of Appeals of Lynn, 397 Mass. 555, 558, 492 N.E.2d 354 (1986). The purpose of notice to the town clerk is to provide "notice to interested persons that the decision of the board of appeals has been challenged and may be overturned." Pierce, supra at 808, 343 N.E.2d 412.

However, "[s]trict compliance with all the details of the notice provision is not required, so long as notice adequate to serve the *393purpose of the provision is given within the period limited." Costello v. Board of Appeals of Lexington, 3 Mass. App. Ct. 441, 443, 333 N.E.2d 210 (1975). By way of example, in McLaughlin v. Rockland Zoning Bd. of Appeals, 351 Mass. 678, 680, 223 N.E.2d 521 (1967), the court concluded that the purpose of the statute was met when the plaintiffs timely filed a copy of their complaint with the town clerk, even though they did not file a separate notice stating that it had been filed in court. Similarly, the court found notice adequate in Carr v. Board of Appeals of Saugus, 361 Mass. 361, 362-363, 280 N.E.2d 199 (1972), where the plaintiff timely filed a notice of the appeal with the town clerk but did not include a copy of the complaint. In Garfield v. Board of Appeals of Rockport, 356 Mass. 37, 39, 247 N.E.2d 720 (1969), the plaintiffs delivered notice that they had filed an appeal and a copy of the complaint with the town clerk at her home at 6:35 P.M. on the last day of the appeal period, after the town offices had closed. The court held that delivery to the clerk at her home satisfied the notice requirement. Ibid.

Finally, in the circumstances closest to those in the present case, notice was deemed adequate in Konover, supra. In that case, counsel for the plaintiff had prepared two sets of papers for service at the town hall-one for service on the board and the other for delivery to the town clerk. Id. at 320-321, 588 N.E.2d 1365. Both were placed together in a sealed envelope marked "Summonses to the Auburn Planning Board in the Town of Auburn."

*754Id. at 320, 588 N.E.2d 1365. The process server, unaware that the envelope contained two sets of papers, left the sealed envelope with the secretary to the town planner. Ibid. Days later, but within the appeals period, the town planner opened the envelope and walked across the hall to the town clerk's office where he told the clerk and an assistant town clerk that he had received the plaintiff's complaint. Id. at 321, 588 N.E.2d 1365. He showed the assistant town clerk the front page of the complaint-"to see if she received what I had received"-which she had not. Ibid. After that, the town planner placed all of the documents he had received into a file in the board's office, and no formal notice of the appeal was ever filed with the town clerk. Id. at 322, 588 N.E.2d 1365. In concluding that the requirements of § 17 had been met, the court observed that the "key element" in cases "relaxing the rigors of strict compliance with the zoning appeal statute" is that within the twenty-day statutory appeal period "the clerk is actually notified that an appeal-i.e., a complaint-has in fact been timely filed," id. at 324-325, 588 N.E.2d 1365, and that "it is the state of the clerk's knowledge, not the physical location of the papers, that controls."

*3946 Id. at 324-325, 588 N.E.2d 1365.

As we have observed, in the present case it is established that the clerk knew sometime before May 4, 2016, that the plaintiffs had filed a complaint in the Land Court appealing from the decision of the board of April 24, 2016, decision of the board. Since it is the state of the clerk's knowledge that controls, the requirements of G. L. c. 40A, § 17, were satisfied, and the order allowing the defendant's summary judgment motion was error.7

Judgment reversed

It is undisputed that the plaintiffs failed to give timely "[n]otice of the action with a copy of the complaint" to the town clerk as required by G. L. c. 40A, § 17. Nonetheless, they were able to depose the town clerk, the assistant town clerk and the town planner in an effort to establish that the town clerk had actual knowledge of the filing of their complaint. I believe this inquiry into the "actual knowledge" of the clerk removes the burden from where it properly should be placed, squarely on the shoulders of the plaintiffs. Where a party has failed in its statutory notice obligation, local officials should not be drawn into litigation.

I acknowledge that dismissal of an appeal is a severe sanction for failure to give timely notice to the town clerk, particularly where it appears that the plaintiffs timely filed a complaint in court to challenge the decision of the local zoning board of appeals. Given that the requirement of G. L. c. 40A, § 17, is a jurisdictional requisite to judicial review, however, see Garfield v. Board of Appeals of Rockport, 356 Mass. 37, 39, 247 N.E.2d 720 (1969), this requirement must be enforced even where it leads *755to harsh results. *3951 See Bjornlund v. Zoning Bd. of Appeals of Marshfield, 353 Mass. 757, 757, 231 N.E.2d 365 (1967) ; O'Blenes v. Zoning Bd. of Appeals of Lynn, 397 Mass. 555, 558-559, 492 N.E.2d 354 (1986) ; Costello v. Board of Appeals of Lexington, 3 Mass. App. Ct. 441, 442, 333 N.E.2d 210 (1975) ; Bingham v. City Council of Fitchburg, 52 Mass. App. Ct. 566, 566-567, 754 N.E.2d 1078 (2001).

The Hickeys argue that their failure to serve the town clerk with notice of their appeal should be excused because the assistant town clerk was told by the town planner that he had received the Hickeys' complaint. In doing so, they rely primarily on Konover Mgmt Corp. v. Planning Board of Auburn, 32 Mass. App. Ct. 319, 588 N.E.2d 1365 (1992) ( Konover ).

Under the circumstances recited in Konover, this court held that the plaintiff had adequately complied with G. L. c. 40A, § 17. In so doing, we found that the "key element" in cases "relaxing the rigors of strict compliance with the zoning appeal statute" is that within the appeals period "the clerk is actually notified that an appeal-i.e., a complaint, has in fact been timely filed." Id. at 324-325, 588 N.E.2d 1365. Referring to Garfield, supra, the Konover court wrote, "[t]he decision makes it clear that it is the state of the clerk's knowledge, not the physical location of the papers, that controls." Konover, supra at 325, 588 N.E.2d 1365. In Garfield, however, the court did not discuss the state of the clerk's personal knowledge as a basis for its decision. Instead, the court relied on the statutory language-emphasizing *396that, in contrast to G. L. c. 40A's provisions for filing the board's decision "in the office of the city or town clerk," the language relevant to judicial appeals required only that notice be given "to ... (the) city or town clerk," and did not require filing in the clerk's "office." Garfield, supra at 39, 247 N.E.2d 720.

There is, however, another "key element" that is apparent from Konover and the cases cited therein-which is that, before the notice requirement had been "relaxed," there had been an attempt by the plaintiff to provide the clerk with written notice of the appeal by some reasonably effective (albeit imperfect) means. See Konover, supra at 321, 588 N.E.2d 1365 (counsel sent out notice packet for service on town clerk). See also, McLaughlin v. Rockland Zoning Board of Appeals, 351 Mass. 678, 679, 223 N.E.2d 521 (1967)

*756(complaint was delivered to town clerk without a notice of filing); Garfield, 356 Mass. at 39, 247 N.E.2d 720 (notice and copy of complaint were delivered to clerk at home, after close of business); Carr v. Board of Appeals of Saugus, 361 Mass. 361, 361, 280 N.E.2d 199 (1972) (notice of filing was delivered to town clerk without complaint).

Moreover, in all of these cases, the clerk's "actual knowledge" of the appeal has been linked in some way to the attempt by the plaintiff to serve her with notice.2 See Konover, supra at 321, 588 N.E.2d 1365 (town planner received notice intended for clerk and informed clerk that appeal had been filed). See also, McLaughlin, supra at 679, 223 N.E.2d 521 ; Carr, supra at 361, 280 N.E.2d 199 ; Garfield, supra at 39, 247 N.E.2d 720.

In other words, in my view, Konover does not stand for the proposition that a clerk's actual knowledge of a pending appeal is necessarily dispositive of the jurisdictional question, regardless of the source from which that knowledge might flow.3 Such an exception, in all cases where the clerk has learned of an appeal by *397some happenstance independent of the plaintiff's efforts at perfecting the appeal, could negate entirely the statutory requirement that timely notice be provided to the clerk. Moreover, such an exception would have the effect of requiring town clerks (as well as other town officials) to submit to litigation discovery in every instance where the plaintiff has failed to give the formal notice required by the statute.4 While Konover and Garfield "expanded the manner in which the deadline could be met," see Bingham, supra at 571, 754 N.E.2d 1078, I *757do not believe this expansion is broad enough to encompass this situation where there has been no attempt by the plaintiff to provide the written notice to the clerk required by the statute.

Written notice is contemplated by the statute's reference to "notice of the action with a copy of the complaint." G. L. c. 40A, § 17. See County of Norfolk v. Zoning Board of Appeals of Walpole, 16 Mass. App. Ct. 930, 930, 450 N.E.2d 628 (1983) (telephone notice that appeal will be taken is nugatory because it puts nothing in record by which interested third parties would be forewarned that zoning status of land is still in question). By relying on an oral representation to satisfy the notice requirement to the town clerk, the majority further extends the exceptions to the rule. See McLaughlin, supra (copy of complaint filed with clerk); Garfield, supra (notice of appeal and copy of complaint delivered to clerk); Carr, supra (notice of appeal filed with clerk); Konover, supra (copy of complaint shown to clerk).

For these reasons, I would hold that a plaintiff seeking judicial *398zoning review is not entitled to the benefit of the town clerk's personal knowledge for purposes of satisfying G. L. c. 40A, § 17, unless that knowledge can reasonably be connected to a timely attempt to provide formal, written notice to the clerk by some reasonably effective means. Such a rule is consistent with Konover, where the court emphasized the details of the plaintiffs' counsel's attempted service on the clerk's office, and found that his failure to do so was a " 'relatively innocuous' misstep that was not 'so repugnant to the procedural scheme, so destructive of its purposes, as to call for dismissal."5 Konover, supra at 327, 588 N.E.2d 1365, quoting from Schulte v. Director of the Div. of Employment Sec., 369 Mass. 74, 79, 337 N.E.2d 677 (1975).

Here, because the plaintiffs served only the board and made no attempt to provide separate notice to the town clerk, as required by the statute, I believe the appeal was properly dismissed by the Land Court. See Pasqualino v. Board of Appeals of Wareham, 14 Mass. App. Ct. 989, 990, 440 N.E.2d 523 (1982). I would affirm.
