Over twenty-four centuries ago, a Greek philosopher warned that “[hjaste in every business brings failures.” VII Herodotus, Histones, ch. 10. This appeal illustrates that courts are no exception to the rule. The tale follows.
I
Plaintiffs, former members of the Zoning Board of Appeals of Tewksbury, Massachusetts, claimed that defendants (the town and various municipal officials) had ousted them in derogatiоn of their First Amendment guarantees. They brought this civil rights action in federal district court seeking, inter alia, reinstatement and money damages. The case proceeded uneventfully through the discovery phase. The day of trial found the parties ready for a full-dress courtroom confrontation. But even as the attorneys surveyed prospective jurors, a visiting judge, new to the ease, directed defendants to move then and there for summary judgment. The judge accepted a perfunctory oral motion and gave the parties thirty minutes in which to prepare for argument. Plaintiffs objected to this procedure without avail. Following a hearing that consisted mainly of counsels’ haranguing, the judge again brushed aside plaintiffs’ protest anent the procedure and informed thе parties that he would issue a bench decision three days later. When the litigants appeared as ordered, a further exchange occurred, culminating in the entry of summary judgment for defеndants. This appeal ensued.
*55 Although we understand defendants’ entreaties that we turn a blind eye to procedural irregularities and focus instead on whether the presence of genuine issues of material fact can be discerned, we decline to delve into the substantive aspects of plaintiffs’ cause of action. Given the case’s posture, leapfrogging to the merits would display much the same disregard for established protocol that marred the district court’s performance. Courts cannot make up new rules as they go along, whether to prоmote notions of judicial economy or to suit a judge’s fancy. Because the lower court employed a flawed procedural regime, we reverse its ruling, vacate the judgment, and reinstate the case for trial. 1

Although defendants moved orally for summary judgment, their motion was made at the direction of the court. Placing substance over form, we regard what transpired as the functional equivalent of a
sua sponte
grant of summary judgment. To be sure, district courts possess the power to trigger summary judgment on their own initiative,
see, e.g., Jardines Bacata, Ltd. v. Diaz-Marquez,
Although summary judgment is a useful shortcut leading to final adjudication on the merits in a relatively small class of cases, its proper province is to weed out claims that dо not warrant trial rather than simply to clear a court’s docket. To allow summary judgment, a court must find, after studying the parties’ evidentiary proffers and giving the benefit of reasonable doubt to those against whom the motion is directed, that there is no genuine issue of material fact in dispute and that the motion’s proponent is entitled to judgment as a matter of law. See Fed. R.Civ.P. 56(c). Since Rule 56 provides in part that motions for summary judgment “shall be served at least 10 days before the time fixed for the hearing,” and expressly allows nonmovants to “serve opposing affidavits” at any time priоr to the day of the hearing, id., summary judgment targets should be secure in the knowledge that they will have at least ten days in which to formulate and prepare their best opposition to an impending motion. In our view, this notice requirement is not mere window dressing.
Sua sponte
summary judgments are a special subset. There are two particular conditions precedent that attach when the subset is deployed. First, the discovery phase must be sufficiently advanced that the court can make an accurate determination of “whether a genuine issue of material fact does or dоes not exist,”
Jardines Bacata,
*56
Waiver aside,

it is well settled in this circuit that all summary judgmеnt proceedings, including those initiated by the district judge, will be held to the standards enunciated in Rule 56 itself.
See Donate-Romero v. Colorado,
Ill
Against this backdrop, it is painfully apрarent that the case at bar comprises an especially egregious example of a court, obviously well intentioned, nonetheless unfairly sandbagging litigants. When plaintiffs appеared for trial, they had no inkling that the judge might entertain, let alone initiate, a hearing on summary judgment. 3 By like token, plaintiffs were afforded thirty minutes, rather than the minimum period of ten days allotted by Rule 56, in order to prepare for the hearing and marshal their evidence in opposition to brevis disposition. It is, moreover, no sufficient answer to say that plaintiffs were on notice to be рrepared for trial; trial preparation is neither the same as, nor an acceptable substitute for, the special sort of preparation, e.g., securing affidavits, needed to oppose a motion for summary judgment.
In addition to the flaws already discussed, the procedure employed below contained a further vice. The “motion” for summary judgment was never reduced to writing and, in point of fact, was never fully articulated either by defendants’ counsel or by the district judge. It is a bedrock rule of civil litigation that a party who has exercised due diligence is entitled to be apprised of his opponent’s theory of the case, and that rule has particular force in the summary judgment milieu. See, e.g., D.Mass.Loc.R. 56.1 (stipulating that motions for summary judgment must “include a concise statement of the material facts of record as to which the moving party contends there is no genuine issue to be tried,” together with paginated references to deposition transcripts and other relevant documentation). The rule was flouted in this instance.

We need go no further. 4 Sua sponte summary judgment is a remedy which, although available, must be handled with care. In this tricky area of the law, an unduе emphasis on speed is a surefire way to court reversal. So it is here: having determined that the proceedings below were undertaken too hastily and without a proper proрhylaxis, we sustain the appeal.

Notes
. We express no opinion as to whether defendants should be allowed, at this late date, to file a properly authenticated motion for summary judgment in the court below. That matter — as well as the related matter of the viability of such a motion, if filed — is for the district court.
. In the summary judgment context as elsewhere, notice can be waived.
See, e.g., Osbakken
v.
Venable,
. Defendants had not previously filed any dispos-itive motions despite the fact that the suit had been pending for over two years.
. We recognize that, in some jurisdictions, improper notice anent a summary judgment initiative may be considered harmless error, circumstances permitting.
