The plaintiffs in these cases were members of the certified plaintiff class in Haverty v. Commissioner of Correction, 437 Mass. 737 (2002) (Haverty), an action for declaratory and injunctive relief, in which we held that inmates at the Massachusetts Correctional Institution at Cedar Junction (Cedar Junction) must be afforded the due process procedures set forth in the regulatory scheme governing the former departmental segregation unit (DSU), 103 Code Mass. Regs. §§ 421.00 (1994) (DSU regulations), before being segregated in restrictive conditions in the so-called East Wing of the prison for nondisciplinary reasons. Id. at 762-763. In separate actions filed in the Superior Court, the plaintiffs sought compensatory and punitive damages for the time they spent confined in the East Wing alleging that they had been deprived of the procedural safeguards to which they were entitled. The defendants raised, by means of motions to dismiss filed pursuant to Mass. R. Civ. P. 12 (b), 365 Mass. 754 (1974), the affirmative defenses of res judicata and qualified immunity. After hearing arguments on both motions, a judge in the Superior Court concluded that the plaintiffs’ claims for damages were not barred by their prior class action for declaratory and injunctive relief. The judge, however, allowed the defendants’ motions on the ground of qualified immunity, concluding that the defendants had not violated “clearly established statutory or constitutional rights” when they assigned prisoners to the East Wing in disregard of the DSU regulations. The parties filed cross appeals, and the appeals were consolidated in the Appeals Court. We transferred the cases here on our own motion and now affirm the judgments of dismissal.
1. A description of the background events precipitating these appeals is recited in full in Haverty. See id. at 741-747. We summarize the material facts. Litigation challenging conditions in the State correctional system, in which inmates were held in near solitary confinement in the DSU at Cedar Junction and at the Massachusetts Correctional Institution at Norfolk, for [414]*414indeterminate periods of time and for reasons other than disciplinary sanctions, resulted in a single justice of this court directing the department to promulgate new regulations, applicable to all State correctional facilities, governing the transfer of inmates from the general prison population to any DSU unit. See Hoffer vs. Fair, No. SJ-85-0071 (Mar. 3, 1988). In 1993, those regulations were enacted and are now codified at 103 Code Mass. Regs. §§ 421.00.3
In 1995, in response to escalating levels of gang-related incidents, and an increasingly violent prison population throughout the department, the commissioner decided to eliminate use of the DSU and to divide Cedar Junction (at that time the Commonwealth’s only maximum security prison) into two “wings,” the East Wing and the West Wing.4 The East Wing consists of eight units, each with forty-five one-man cells; the West Wing has three units, each with seventy-two one-man cells. Conditions are materially more restrictive in the East Wing. There, inmates are held in virtual solitary confinement for twenty-two and one-half hours each day; have only limited recreational time and few job opportunities; and eat all meals in [415]*415their cells.5 Inmates housed in the West Wing, by contrast, are allowed out of their cells for as much as fifteen hours each day (all day on weekends) and interact with other prisoners throughout those times. They eat meals in a communal dining hall and enjoy greater visitor privileges than those in the East Wing. Assignment to the East Wing generally is not imposed for a specific disciplinary offense, but rather to allow prison officials to maintain control of the prison population and to secure the safety of prisoners and staff. Until the time of our decision in Haverty, no procedural protections were provided before a prisoner was placed in the East Wing, or during the time he remained there, beyond the six-month classification review received by all prisoners in the system pursuant to 103 Code Mass. Regs. § 420.09 (1995) (entitling all prisoners housed in any correctional facility in Commonwealth, no matter the level of security, to receive review of their status every six months). Placement in the East Wing, and the amount of time a prisoner remained there, was solely at the discretion of the superintendent of Cedar Junction. See Haverty, supra at 746. The Haverty plaintiffs, certified as a class of “all prisoners who are now confined or may at some point be confined at [Cedar Junction] in any housing unit other than the DDU” (see note 5, supra), sought injunctive relief against the practice of placing prisoners in segregated confinement in the East Wing for nondisciplinary reasons, absent compliance with the DSU regulations. Relying on numerous decisions of this court, and of the Appeals Court, suggesting, in essence, that, where conditions in a segregated unit, however named by correction officials, are substantially similar to those in the DSU, the unit must be dealt with as a DSU, at least for purposes of procedural requirements, the plaintiffs contended that the conditions of isolation in the East Wing were nearly identical to those in the DSU and, therefore, [416]*416that the department’s failure fully to comply with DSU regulations before placing or transferring an inmate to the East Wing was unlawful. See, e.g., Longval v. Commissioner of Correction, 404 Mass. 325, 330 (1989) (to prevail on State due process claim, plaintiff required to show substantial similarity between DSU and administrative segregation unit at the Massachusetts Correctional Institution at Concord); Kenney v. Commissioner of Correction, 393 Mass. 28, 34 (1984) (inmate may be transferred to DSU only in compliance with departmental regulations); Royce v. Commissioner of Correction, 390 Mass. 425, 429-430 (1983) (prison officials may not abuse discretion by confining inmates in restrictive housing under “awaiting action status” as means to accomplish punishment immune to procedures set forth in [former] DSU regulations); Gilchrist v. Commissioner of Correction, 48 Mass. App. Ct. 60 (1999); DeLong v. Commissioner of Correction, 46 Mass. App. Ct. 353, 355-358 (1999); Martino v. Hogan, 37 Mass. App. Ct. 710, 721 (1994). We agreed with this position and, in a divided decision, held that the department may not lawfully place prisoners in the East Wing without first affording them the procedural protections required by the DSU regulations. See Haverty, supra at 740.6 In order to effectuate our decision in “an orderly and safe manner,” we remanded the case to the Superior Court to determine the timing and manner of implementing the procedures required by the regulations. See id. at 764. 7
2. As the parties moving for dismissal on res judicata grounds, [417]*417the defendants have the burden of establishing the elements of claim preclusion. See Kobrin v. Board of Registration in Med., 444 Mass. 837, 843 (2005). The defendants have not met their burden in this case. Although our cases in this area are few, we see no reason why the doctrine of claim preclusion would not apply to class action litigation, so that a valid, final judgment is conclusive on all of the members of a plaintiff class.

See Haverty, supra at 740.6 In order to effectuate our decision in “an orderly and safe manner,” we remanded the case to the Superior Court to determine the timing and manner of implementing the procedures required by the regulations. See id. at 764. 7
2. As the parties moving for dismissal on res judicata grounds, [417]*417the defendants have the burden of establishing the elements of claim preclusion. See Kobrin v. Board of Registration in Med., 444 Mass. 837, 843 (2005). The defendants have not met their burden in this case. Although our cases in this area are few, we see no reason why the doctrine of claim preclusion would not apply to class action litigation, so that a valid, final judgment is conclusive on all of the members of a plaintiff class. See Aspinall v. Philip Morris Cos., 442 Mass. 381, 397 n.19 (2004). The doctrine only operates, however, to bar further litigation of “all matters that were or should have been adjudicated in the [original class] action.” Heacock v. Heacock, 402 Mass. 21, 23, 24 (1988) (explaining doctrine as ramification of policy considerations underlying mie against splitting cause of action). See O’Neill v. City Manager of Cambridge, 428 Mass. 257, 259 (1998). It does not apply in circumstances where a party has neither the incentive, nor the opportunity, to raise the claim in an earlier lawsuit. See id., and cases cited. In Aspinall v. Philip Morris Cos., supra, we suggested that, in circumstances where the unique experiences of potential members of a plaintiff class would defeat the “commonality of interests” requirement for class certification pursuant to G. L. c. 93A, principles of claim preclusion would not operate to bar a class member from future pursuit of claims for personal injury unsuitable for class treatment. The same principles of fairness and judicial efficiency hold true with respect to a class certified, as was the Haverty class, under Mass. R. Civ. P. 23, 365 Mass. 767 (1974), a rule which, like G. L. c. 93A, does not allow a member of a certified class not wishing to be bound by the class litigation to “opt out.” See J.W. Smith & H.B. Zobel, Rules Practice § 23.2, at 94 (1975) (“the standard for binding absentees by a class action judgment is simply fundamental fairness”).8
This position accords with Federal law.9 In fact, it appears that “every federal court of appeals that has considered the [418]*418question has held that a class action seeking only declaratory or injunctive relief does not bar subsequent individual suits for damages.” Hiser v. Franklin, 94 F.3d 1287, 1291 (9th Cir. 1996), cert. denied, 520 U.S. 1103 (1997). See Fortner v. Thomas, 983 F.2d 1024, 1030-1032 (11th Cir. 1993) (“It is clear that a prisoner’s claim for monetary damages or other particularized relief is not barred if the class representative sought only declaratory and injunctive relief, even if the prisoner is a member of a pending class action”); 18A C.A. Wright, A.R. Miller, & E.H. Cooper, Federal Practice and Procedure § 4455, at 460-464 (2d ed. 2002) (“an individual who has suffered particular injury as a result of practices enjoined in a class action should remain free to seek a damages remedy even though claim preclusion would defeat a second action had the first action been an individual suit for the same injunctive relief”).
3. We turn now to the defendants’ claim of qualified immunity. “[Gjovemment officials performing discretionary functions generally are shielded from liability for civil damages insofar as their conduct does not violate clearly established statutory or constitutional rights of which a reasonable person would have known.” Rodriques v. Furtado, 410 Mass. 878, 882 (1991), quoting Harlow v. Fitzgerald, 457 U.S. 800, 818 (1982). See Shedlock v. Department of Correction, 442 Mass. 844, 859 (2004). The standard is entirely objective. See Harlow v. Fitzgerald, supra at 815-816 (subjective standard incompatible with policy rationale of precluding insubstantial lawsuits from proceeding to trial); Clancy v. McCabe, 441 Mass. 311, 322-323 (2004), quoting Anderson v. Creighton, 483 U.S. 635, 640 n.2 (1987) (objective standard promotes policy that “insubstantial claims against government officials be resolved prior to discovery and on summary judgment if possible”).10 In order to overcome an asserted defense of qualified immunity, the right [419]*419must be clearly established at the time of the alleged violation. See Siegert v. Gilley, 500 U.S. 226, 232 (1991). To be “clearly established” for purposes of qualified immunity, the contours of the right allegedly violated must be sufficiently definite so that a reasonable official would appreciate that the conduct in question was unlawful. See Shedlock v. Department of Correction, supra, citing Anderson v. Creighton, supra at 640. The United States Court of Appeals for the First Circuit has noted that “qualified immunity sweeps so broadly that ‘all but the plainly incompetent or those who knowingly violate the law’ are protected from civil rights suits for money damages.” Hegarty v. Somerset County, 53 F.3d 1367, 1373 (1st Cir. 1995), quoting Hunter v. Bryant, 502 U.S. 224, 229 (1991).
Analysis of the qualified immunity defense generally requires a two-part inquiry into whether, “[t]aken in the light most favorable to the party asserting the injury ... the facts alleged show the officer’s conduct violated a constitutional right,” and, if so, whether the right was clearly established so that “it would be clear to a reasonable officer that his conduct was unlawful in the situation he confronted.” Gutierrez v. Massachusetts Bay Transp. Auth., 437 Mass. 396, 403-404 (2002), quoting Saucier v. Katz, 533 U.S. 194, 201, 202 (2001). In light of our holding in Haverty, only the second inquiry is in issue here.
As far back as 1983, a reasonable prison official would have known that a prisoner could not lawfully be assigned to the DSU without abiding by mandatory language contained in regulations, then in effect, governing the placement of prisoners in the DSU. See Royce v. Commissioner of Correction, 390 Mass. 425, 427-428 (1983) (“Once an agency has seen fit to promulgate regulations, it must comply with those regulations,” citing regulations governing DSU placement then in effect, 103 Code Mass. Regs. §§ 421.01 et seq. [1978]). See also Kenney v. Commissioner of Correction, 393 Mass. 28, 34 (1984) (inmate may be transferred to DSU only in compliance with departmental [420]*420regulations). In 1989, we reaffirmed this principle and extended its application to a challenge, brought by the plaintiff Longval, to his transfer, on two occasions, to an administrative segregation unit at the Massachusetts Correctional Institution at Concord (Concord), without a hearing and the prior authorization of the commissioner, as required by G. L. c. 127, § 39, and by DSU regulations then in effect. See Longval v. Commissioner of Correction, 404 Mass. 325, 327 (1989). We held that, in order to prevail on that aspect of his summary judgment motion concerned with violations of DSU regulations, the plaintiff was required to show that there was no dispute of material fact as to the “substantial similarity” between the DSU and the administrative segregation unit in which he had been held. See id. at 330. We cautioned that “[c]ertainly, the department and the commissioner may not sidestep statutory and regulatory provisions stating the rights of an inmate as to his placement in a DSU by assigning as a pretext another name to such a unit.” Id. at 328-329, citing Royce v. Commissioner of Correction, supra at 429-430.11 In Hoffer v. Commissioner of Correction, 412 Mass. 450 (1992), we again clarified that departmental compliance with DSU regulations, before removing a prisoner from the general prison population and isolating him in the DSU, is constitutionally required and emphasized that the department’s failure to so comply would, in appropriate cases, entitle a prisoner to “compensation, beyond nominal damages, for the loss of liberties which resulted from the deprivation of due process.” Id. at 455.
In 1995, in Sandin v. Conner, 515 U.S. 472 (1995), the Supreme Court of the United States abandoned its prior methodology for analyzing claims brought by State prisoners alleging that conditions of their confinement amounted to an [421]*421unconstitutional deprivation of due process, and concluded that the due process clause is implicated only when the challenged deprivation involves an “atypical and significant hardship on the inmate in relation to the ordinary incidents of prison life.” Id. at 484. See DeLong v. Commissioner of Correction, 46 Mass. App. Ct. 353, 355-358 (1999) (providing in-depth Sandin analysis). In subsequent actions brought by prison inmates alleging due process violations for noncompliance with procedures allegedly due them, the plaintiffs generally attempted to demonstrate, as a factual matter, that the conditions of their confinement imposed an “atypical and significant hardship” that created a protected liberty interest under Sandin v. Conner, supra, or that the conditions were substantially the same as those in the former DSU and, thus, compliance with DSU regulations was mandatory under State law.
In 1996, on consideration of a motion for summary judgment filed by the plaintiff in Gilchrist v. Commissioner of Correction, 48 Mass. App. Ct. 60 (1999), a judge in the Superior Court issued a declaratory judgment stating that placement of prisoners in the so-called “Phase III” unit of the East Wing (a designated restrictive unit that, apparently, was the product of organizational changes preceding the 1995 reorganization at Cedar Junction), absent compliance with the DSU regulations, was unlawful. See id. at 62. The judge enjoined the commissioner and prison officials from placing the Gilchrist plaintiff in the Phase BJ unit without affording him those rights contained in the DSU regulations. See id. In 1999, the Appeals Court vacated the declaration and the injunction, concluding that there was a genuine issue whether conditions in the Phase IB unit were, in fact, the “substantial equivalent” of the DSU and remanded the case to the Superior Court for such a determination. Id. at 64-66 (“the factual material upon which the judge based her conclusion . . . while indicating that the restrictions imposed on the two groups of inmates may be equally harsh, does not present a sufficiently full picture of their living conditions to justify the award of summary judgment”). In another case decided by the Appeals Court earlier that year, DeLong v. Commissioner of Correction, 46 Mass. App. Ct. 353, 355, 357 (1999), the focus was on whether the plaintiffs “punitive segregation” in [422]*422a “modular unit” at Cedar Junction imposed an “atypical and significant hardship” that would create a liberty interest under Sandin v. Conner, supra. The Appeals Court again remanded the case to the Superior Court for a factual analysis of the particular conditions of the plaintiffs confinement. See DeLong v. Commissioner of Correction, supra at 357-358. See also Martino v. Hogan, 37 Mass. App. Ct. 710, 721 (1994).
Consideration of the above cases leads us to conclude that, at the time that the plaintiffs were held in segregated confinement in the East Wing, in 1996 and throughout October, 2002, it was “clearly established” that the law required department officials to afford inmates the procedural protections contained in the DSU regulations before placing them in segregated conditions that were substantially similar to those in the former DSU. It remained a legitimate factual question, however, whether the conditions in the East Wing, under which the plaintiffs were held, sufficiently mirrored those in the former DSU so as to make compliance with the DSU regulations mandatory, as a matter of “clearly established” State law, before prisoners were placed there.12 While Haverty resolved that question, the defendants could have reasonably (but we now know mistakenly) concluded, prior to October 10, 2002, the date the Haverty opinion was issued, that the law did not compel their compliance with the DSU regulations.13 Even then, in a strongly worded dissent in Haverty, three Justices [423]*423of this court stood by the position that DSU regulations were not applicable to the East Wing and that the court’s holding otherwise was, in fact, “contrary to their purpose and the judicial and regulatory history leading to their enactment.” Haverty, supra at 764 (Cordy, J., dissenting, with whom Cowin and Sosman, JJ., joined). Although the dissenting Justices acknowledged points of similarity between conditions in the East Wing and the DSU, they also argued the existence of what were, in their views, significant and material differences between the two units. See id. at 767-768 (Cordy, J., dissenting, with whom Cowin and Sosman, JJ., joined).
In Haverty, we declared in unambiguous terms that compliance with DSU regulations is mandatory, under State law, before prison officials may transfer a prisoner to the East Wing. See id. at 762-763. If Justices on this court reasonably could differ as to whether conditions in the East Wing call DSU regulations into play, however, it cannot fairly be said that a reasonable official would have understood their applicability. In the wake of Haverty, when a different member of the Haverty plaintiff class, Kevin Dahl, sought monetary compensation, pursuant to 42 U.S.C. § 1983 (2000), for his invalid confinement in the East Wing absent compliance with DSU regulations, the Appeals Court, in an unpublished memorandum of decision, concluded that qualified immunity was available to the defendants because the law, before our decision in Haverty, was not “clearly established.” See Dahl v. Commissioner of Correction, 61 Mass. App. Ct. 1118 (2004). This result was so obvious that the [424]*424Justices, on the panel decided the appeal under the court’s rule 1:28, a matter of disposition reserved for cases and issues lacking substantial merit. The conclusion in the Dahl case was correct. Based on the law discussed, the defendants have the benefit of qualified immunity.
4. The judgments of dismissal are affirmed.
So ordered.
