Because this is an interlocutory appeal which involves us but peripherally in the merits of the case, we offer an abbreviated account of the proceedings and a decurtate explanation concerning the lone matter which lies within our present ken.
I
Plaintiff-appellee Dennis J. Domegan, a state prisoner, sued various administrators and correctional officials at the Massachusetts Correctional Institute — Walpole (MCI-Walpole), claiming that they had run afoul of 42 U.S.C. § 1983 and the Massachusetts Civil Rights Act, Mass.Gen.Laws ch. 12, §§ 11H & 111 (West 1986), in several ways: (1) inflicting cruel and unusual punishment upon him in violation of the Eighth and Fourteenth Amendments to the United States Constitution and the Massachusetts Declaration of Rights, (2) depriving him of liberty without due process of law contrary to the Fourteenth Amendment, and (3) interfering with rights secured by state law. Defendants (appellants before us) sought partial summary judgment on the basis that they were quali-fiedly immune from the prayers for money damages.
See generally Anderson v. Creighton,
— U.S. -,
II
Defendants want to bite off far more than we can allow them to chew. They profess to seek immediate review of (1) the grant of partial summary judgment in plaintiffs favor, (2) the denial of their cross motion for
brevis
disposition on qualified immunity grounds, and (3) the rebuff of their effort to obtain reconsideration and clarification. Yet all three of these rulings are interlocutory; none are “final decisions” within the meaning of 28 U.S.C. § 1291. Because finality is lacking, they are not immediately appealable “unless appellate jurisdiction attaches in some other fashion.”
In re Recticel Foam Corp.,
The middle item in this list of three —the order refusing partial summary judgment on the ground of qualified immunity —is properly before us under the collateral-order exception to the finality rule.
See Mitchell v. Forsyth,
It is too plain to warrant citation of authority that the district court’s grant of partial summary judgment in Domegan’s favor — a grant which left unresolved his Eighth Amendment and state-law claims, and which, as to due process, adjudicated only liability and not damages — is not a final order; it cannot be said to “resolv[e] the contested matter, leaving nothing to be done except execution of the judgment.”
United States v. Metropolitan Dist. Comm’n,
III
On the main issue, we conclude that the record amply supports the district court’s rejection of appellants’ Rule 56 motion. To explicate our thinking, we look first at the facts as pleaded, and then at the applicable law. In the course of this exposition, we undertake neither to resolve conflicts in the record nor to effectuate credibility determinations. We instead “accept[ ] at face value the facts as presented by [the nonmov-ant],”
Bonitz,
A. Factual Mosaic. Plaintiff’s relevant factual averments, repeated under oath, are as follows. During the spring of 1983 Domegan was housed in the departmental segregation unit at MCI-Walpole. The prison then had a policy, known as the Alternate Feeding Program (AFP), which placed inmates who had thrown food or human waste on a specially administered diet for several successive days. 3 While subject to AFP, the affected inmate’s solid steel cell door was shut. During the currency of an AFP impost, the door was opened only when necessary for administrative purposes. This was contrary to the usual practice which prevailed in the segregation unit. The AFP utilized a steady, unvarying diet of bread and cheese, supple *1063 mented solely with the tap water available in the cells. To receive these rations, an inmate was required to turn on the cell’s light and lie face down on his cot. Prison officials styled the AFP as an “administrative remedy;” under that rubric, inmates were afforded neither notice nor any prede-privation procedure by which they could challenge the imposition of the regimen.
Domegan was twice placed on AFP after prison officials unilaterally determined that he had thrown food or waste. During the May confinement (which lasted 7V2 days), Domegan received only four meals. That July, during 5 days under the AFP regimen, he received none. The reason for this enforced asceticism, appellee claims, was that defendants shut off the supply of water and electricity to his cell while he was subject to the AFP. Because he could not switch on the light in order to comply with requirements for receiving even the Spartan fare which the AFP permitted, he went hungry. Appellant further alleges that, even had he received his stipulated allotment of bread and cheese, his diet would still have been nutritionally inadequate.
B.
Discussion.
In this posture of the case, the denial of partial summary judgment evidences the district court’s conclusion that, “if the facts are as asserted by the plaintiff, the defendants] [are] not immune.”
Mitchell,
Qualified immunity is an affirmative defense which, if successfully pleaded and maintained, discharges officials from the need to stand trial on damage claims. The defense is unavailable when an official has violated a “clearly established” right.
Harlow,
Prison officials must act “within the normal limits or range of custody which the conviction has authorized the State to impose.”
Meachum v. Fano,
The Commonwealth concedes that the AFP could not have been permanently or regularly imposed upon a prisoner. Dome-gan has alleged facts sufficient to give credence to his plaint that the programmed diet failed to meet minimum requirements for daily nutritional adequacy. Moreover, taking his sworn allegations as true, as Rule 56 requires, the AFP was imposed under conditions that isolated Domegan for lengthy periods, behind a windowless and constantly closed steel door, without water or electricity. We have scant doubt that in 1983 the state of the law was such that reasonable prison officials should have known that they lacked authority to place an inmate on a nutritionally inadequate diet and simultaneously isolate him for many days without electricity or water without *1064 affording him even the thinnest sliver of due process.
Certainly the statutes and regulations pertaining to state prisoners and prison conditions did not empower appellants to undertake such acts. Quite to the contrary, the Commonwealth’s laws, as applicable at the time, specified that each inmate “shall” be provided a “full” meal each day, even in “isolation units.” Mass.Gen. Laws ch. 127, § 40 (West 1974). Even when in “segregated units,” inmates “shall” be provided “regular meals.” Mass.Gen.Laws ch. 127, § 39 (West 1974). The statutory framework hollowed out no interstice wherein an inmate might be deprived of both “regular” and “full” meals. And the drafters’ use of the imperative form is telling; the statutes undeniably embody “language of an unmistakably mandatory character....”
Hewitt,
In this case, the Commonwealth has not only employed mandatory language, but it has employed language which, on its face, does not contemplate that an inmate may be deprived under any circumstances of the substantive predicate. Thus, not only does the substantive right to a “full” or “regular” meal appear to be guaranteed, but such a right also appears to be virtually absolute. The statutory scheme is clear: at least in non-exigent circumstances, prison officials must provide regular meals to an inmate in segregation and full meals to one in isolation. In neither case was it within their discretion to provide inadequate meals 5 — let alone meals constrained by conditons precedent that a prisoner could not hope to meet.
Appellants’ discretion to deny a convict electricity and water were, at the time, similarly circumscribed. Statutes in force required that cells be outfitted with “light, ventilation and adequate sanitation facilities.” Mass.Gen.Laws ch. 127, § 40 (West 1974). And if the officials had any doubt concerning the statute’s meaning, they need only have consulted the relevant regulations. Had they done so, the requirements of electric light, Mass.Regs.Code tit. 105, §§ 450.340, 450.343 (1979), working toilet and sink, Mass.Regs.Code tit. 105, § 450.113 (1979), and “... a safe and sanitary supply of water ...,” Mass.Regs.Code tit. 105, § 450.126 (1979), would have been apparent to them.
We need not belabor the obvious.
Mitchell
teaches that, on an inquiry such as this, we are not to “consider the correctness of the plaintiff’s version of the facts....”
Let us add one further observation. Faithful to this circuit’s exposition of the
*1065
Mitchell
protocol, we make no distinction at this stage which depends upon the extent to which any individual defendant’s conduct may or may not have contributed to the described harm.
See Bonitz,
Moreover, even if it can be argued that the Court’s later opinion in
Anderson v. Creighton, supra,
has undercut this aspect of the
Bonitz
model — a matter as to which we presently essay no view — it would not avail appellants. All of their pertinent filings below spoke exclusively to their collective liability. No meaningful attempt at individuation was made. It is too familiar to warrant string citation that we will not consider arguments which could have been, but were not, advanced below.
See, e.g., Clauson v. Smith,
For both of these reasons, the matter of differentiated liability is not properly before us at this moment. And because the record, as we read it, contains sworn, fact-specific allegations which demonstrate the unquestionable clarity of the right violated, the district court did not err in denying appellants’ motion for partial summary judgment on qualified immunity grounds.
IV
Appellants have made an additional request which we address briefly. They say that because the district court denied their motion without oral argument and without delineating specific findings and conclusions, we should remand for correction of these perceived shortcomings. 6 In this case, we decline to do so.
As we have stated with echolalic regularity, the district courts have considerable discretion in deciding whether or not to allow oral argument on a dispositive motion.
E.g., Cia. Petrolera Caribe, Inc. v. Arco Caribbean, Inc.,
In this case, eschewal of oral argument was well within the pale: the question was an essentially legal one, the matters pertaining to qualified immunity were adequately documented, and the parties’ contentions were fully developed. Ordinarily, a district court will not be held to have misused its discretion in refusing argument when the complaining party can “point[ ] to no single, definable aspect of its position which could not have been adequately presented by a written submission.”
HMG Property Investors, Inc. v. Parque Industrial Rio Canas, Inc.,
Nor does the lack of specific findings constitute a meaningful assignment of error. The Civil Rules specifically direct that “[fjindings of fact and conclusions of law are unnecessary on decisions of motions under Rules 12 or 56_” Fed.R. Civ.P. 52(a). The rationale for this provision is patent: by definition, summary judgment can be granted only upon a show *1066 ing that “there is no genuine issue as to any material fact,” FecLR.Civ.P. 56(c), thus rendering district court “factfinding” pleo-nastic.
We do not mean to suggest that written opinions or bench decisions which explicate a trial judge’s reasoning are not useful to an appellate tribunal. We value such insights. Without them, we are sometimes forced to remand in order to apprehend the basis for decision below.
E.g., Pearson v. Fair,
V
We need go no further. Defendants’ motion for partial summary judgment based on the doctrine of Harlow immunity was appropriately rejected at this stage of the proceedings. Moreover, it was within the district court’s discretion to determine that motion without either (1) oral argument, or (2) the filing of a written opinion. And, as we explain in the text, we do not have jurisdiction to consider presently any of the other matters which appellants seek to raise.
The order denying partial summary judgment on qualified immunity grounds is affirmed. The case is remanded to the district court for further proceedings. Costs to appellee.
Notes
. As we have said before, our collateral-order jurisdiction depends on the existence of four essentials:
The order must involve: (1) an issue essentially unrelated to the merits of the main dispute, capable of review without disrupting the main trial; (2) a complete resolution of the issue, not one that is "unfinished” or “inconclusive"; (3) a right incapable of vindication on appeal from final judgment; and (4) an important and unsettled question of controlling law, not merely a question of the proper exercise of the trial court’s discretion.
United States v. Sorren,
. We acknowledge that our precedents are somewhat murky as to whether we must, on a
Mitchell
motion, go beyond the complaint to ascertain whether the record as a whole presents some genuine issue as to a material fact sufficient to bar qualified immunity.
Compare, e.g., Feliciano-Angulo v. Rivera-Cruz,
.The AFP, as described herein, has not been used at MCI-Walpole since November 1, 1983. It has been replaced by modified versions which, at last glance, bore little resemblance to the original.
. Although this is so, the procedural due process requirements which attend administrative confinement are considerably less formal than those which attend disciplinary segregation.
Compare, e.g., Hewitt v. Helms,
. We express no opinion as to whether or not the mandated menu of bread, cheese, and water was so nutritionally deficient as to transgress either the Constitution or applicable statutes and regulations. We note merely that Domegan has alleged such a deficiency and has created a genuine issue of fact as to it. This allegation, given the stipulated diet, is not so implausible that it can be disregarded at this stage of the proceedings.
. Insofar as the request implicates rulings other than the denial of qualified immunity, it is beyond the scope of our interlocutory reconnaissance, and we take no view of it.
