¶1(concurring). I agree that the convictions should *345be affirmed. I also agree with the majority’s reasoning in the cases involving Gomes, Taylor, and Aguinaldo Fernandes. In the case involving Amaldo Fernandes (Amaldo), however, I do not believe that affirmance of the conviction requires the discussion set forth in part 5 of the majority’s opinion, nor do I believe that affirmance requires us to reach out for the majority’s broad and sweeping declaration, ante at 333, that “an individual may not forcibly resist even an unlawful entry into his residence by one who he knows or has good reason to believe is a police officer engaged in the performance of his duties.”
¶2As the majority observes, Arnaldo argues here that he received ineffective assistance of counsel because his attorney failed to request an instruction to the effect that “an official’s attempt to enter a home illegally entitles the defendant to use reasonable force to resist the entry.” He argues that
“[t]he jury should have been so [instructed] in order to properly assess whether the officers used excessive force in attempting to arrest [Amaldo], his brother, and their guests, and in determining whether [Amaldo’s] attempt to close the door, per the officers’ testimony, constituted an assault and battery.”
¶3Neither rationale, however, entitled Amaldo to the instruction he claims his attorney failed to seek. Insofar as forceful resistance of an arrest is concerned, Commonwealth v. Moreira, 388 Mass. 596 (1983), squarely held that individuals are not entitled to use force to resist even an unlawful arrest. Insofar as the door closing was concerned, Amaldo was convicted of assaulting two officers, Coyne and Tse, only one of whom, Coyne, was at the door when Amaldo was attempting to close it. Arnaldo also had been charged with assault and battery by means of a dangerous weapon, i.e., the door, on Coyne. At the close of the Commonwealth’s evidence, however, the judge entered a required finding of not guilty in Amaldo’s favor on the dangerous weapon charge because there had been no evidence that Arnaldo “struck” Coyne with the door. Accordingly, Amaldo did not need the jury’s assessment of whether the force he applied *346to the door amounted to an assault and battery; the judge already had ruled that it did not.
¶4Beyond that, it is virtually inconceivable that failure to give the requested instruction, under whatever rationale, materially affected the outcome of Amaldo’s trial. The absence of a material impact, without more, means that Amaldo cannot prevail on his claim of ineffective assistance, for we have said many times that
“[t]o prevail on a claim of ineffective assistance of counsel, a defendant must establish (1) that his representative’s performance reflected ‘serious incompetency, inefficiency, or inattention . . . falling measurably below that which might be expected from an ordinary, fallible lawyer,’ Commonwealth v. Saferian, 366 Mass. 89, 96-97 (1974); and (2) that these shortcomings deprived him of ‘an otherwise available, substantial ground of defence’ or otherwise materially affected the outcome of his trial. Id. at 96. See Commonwealth v. Fanelli, 412 Mass. 497, 503 (1992).”
¶5Commonwealth v. Scullin, 44 Mass. App. Ct. 9, 11 (1997).
¶6Only two percipient witnesses, Officer Coyne and Amaldo, testified about the events at the door. If the jury believed Arnaldo, then no assault and battery of any kind occurred.
¶7That being the case, I see no reason to use this case as a vehicle for announcing a broad new rule that one’s fellow citizens assembled and sworn as jurors have no right — under any circumstances — to assess the reasonableness of a forceful but nonassaultive effort to prevent an unbidden policeman’s lawless nighttime entry into a dwelling.
¶8Sanctity of the home is, as the majority recognizes, ante at 341, a core principle in our constitutional order. See Miller v. United States, 357 U.S. 301, 307 (1958); United States v. United States Dist. Ct., 407 U.S. 297, 313 (1972); Commonwealth v. Panetti, 406 Mass. 230, 234 n.5 (1989); Commonwealth v. Marquez, 434 Mass. 370, 374-375 (2001). That principle produced the rule that the official who enters a dwelling with neither warrant nor justification for warrantless entry is a trespasser, see Commonwealth v. Wright, 158 Mass. 149, 159 (1893),
¶9Power conceded, though, the real question is not whether the rule should be restrained but to what degree and under what circumstances. The answer clearly implicates important aspects of the relationship between citizen and State. Providing such answers only when a case clearly requires them is the essence of judicial restraint. See Lockhart v. Attorney Gen., 390 Mass. *349780, 784 (1984); McMaster, petitioner, 12 Mass. App. Ct. 972, 973 (1981). See generally, e.g., Commonwealth v. Bartlett, 374 Mass. 744, 749 (1978); Ruggieri v. Somerville, 10 Mass. App. Ct. 43, 44 (1980). Cf. Bickel, The Least Dangerous Branch: The Supreme Court at the Bar of Politics 114-115 (1962). I would apply that restraint here, decide the case on narrower grounds that are entirely adequate for its disposition, and save consideration of the broader principle the majority has embraced for the case in which the broader principle, as it now exists or as it is reformulated, must necessarily determine the outcome.
¶10-That being the case, Amaldo could have, but did not, request an instruction removing the force he applied to the door as a possible basis for an assault and battery conviction.
¶11Amaldo testified that he opened the door when the police asked him to, responded to their inquiries by telling them he lived there, but declined their requests for proof that he did so. He then tried to close the door, but Officer Coyne put his foot against it to prevent him from doing so. Amaldo then asked Coyne to “kindly remove his foot from [his] property,” suggested that Coyne and Officer Tse go around to the front of the house to ask his mother who he was, and reached for his wallet. As he reached for his wallet, Amaldo testified, Coyne reached in through the then open door, grabbed him by the shirt and, with the assistance of Tse, pulled him out into the yard, threw him against the side of the house, hit him with a flashlight, and sprayed him with mace. He then was handcuffed, beaten, and dragged through some bushes before winding up in a police cruiser.
¶12Officer Coyne testified that, after Amaldo declined to provide his name, and while Coyne had his foot in the door, Coyne told Officer Tse to go to the front of the house to inquire of the mother in accordance with Arnaldo’s request. After Tse left, Amaldo tried to push the door closed. Coyne told him to stop. At that point, Amaldo shoved Coyne in the chest. That prompted Coyne to attempt to place Amaldo under arrest by grabbing his shirt, entering the vestibule of the apartment as he did so. In response, Amaldo
“began hitting Coyne, punching him and kicking him multiple times. Coyne pushed [Amaldo] against the vestibule wall .... [but] could not control [him]. At some point Coyne and [Amaldo] ended up on the floor; Coyne did not know how they got there. Tse was present again, and with Tse’s assistance, Coyne . . . got Amaldo out of the vestibule into the area between the houses. Coyne . . . was able to get one handcuff on [Amaldo] but could not get to the other handcuff .... Coyne eventually assisted in taking [Amaldo] to a police car, but recalls that [Amaldo] was still fighting when he was handcuffed. Coyne also testified that [Amaldo] was dragging his feet and would not walk under his own power; but kept pulling back.”
¶13Coyne’s testimony was, of necessity, recreated by stipulation of the Commonwealth and Amaldo’s attorney after some unexplained mishap resulted in its omission from the official recording of the trial.
¶14Although the issue that Amaldo raises in this case is simply whether use of reasonable force to resist a police officer’s unlawful entry into a dwelling is a defense to a charge of assault and battery, the majority’s rule goes well beyond that issue and, on its face, would prohibit use of force to resist an unlawful entry whether or not that force produced an assault and battery.
¶15I cannot agree that the pertinent language in Commonwealth v. Wrightis dictum. See ante at note 13. The defendants in Wrighthad been charged with assault and battery. The victim was a police officer and “deputy fish commissioner” whom the defendants forcibly repelled when he boarded their sloop to arrest them for trading in short lobsters. The court held that the officer had no right to arrest the defendants without a warrant and then, in the passage of pertinence, stated, “If [the officer] had no right to arrest the defendants without a warrant, and he boarded the sloop for that purpose, he was a trespasser, and the question for the jury would be whether the defendants used excessive force in defending themselves and their property.” 158 Mass. at 159. In support of that proposition, the court cited three cases, one of which, Commonwealth v. Clark, 2 Metc. 23 (1840), dealt solely with a person’s right to use reasonable force to remove trespassers from his property.
