Donna Reilly, Etc. v. United States

Peter Reilly and Donna Reilly, husband and wife, and their minor daughter, Heather, appellees before us, brought this medical malpractice action against the United States pursuant to the Federal Tort Claims Act (FTCA), 28 U.S.C. §§ 1346(b), 2671 et seq. Following a bench trial, the United States District Court for the District of Rhode Island awarded plaintiffs $11,037,-964 in damages and entered a judgment in that amount. Reilly v. United States, 665 F.Supp. 976 (D.R.I.1987) (Reilly I). The defendant moved to set aside the judgment; the district court denied the motion. Reilly v. United States, 682 F.Supp. 150 (D.R.I.1988) (R eilly II). The United States appeals.

Appellant recites an alphabet of error: it claims, among other things, that the court below erred in—

Appointing a technical advisor;

B rushing aside a state collateral source statute;

Calculating lost earning capacity;

Declining to order staggered payments in lieu of a lumpsum award (or in the alternative, refusing to consider the cost of a periodic-payment annuity in determining damages);

Exceeding the amount of plaintiffs’ administrative claim without just cause; and

Fashioning an award which allowed du-plicative recovery.

Given the range and reach of appellant’s contentions, this futhark should be read as more limning than limitary. Yet the appeal is a mixed bag. The government has raised some close questions which deserve careful attention and analysis; we address those in the alphabetical order listed above, except that we merge the third and sixth assignments of error. On the other hand, appellant has also attempted to capitalize on avowals which are patently meritless, or procedurally defaulted, or both; those need not be mentioned specifically, but are rejected out of hand. When everything is said and done, we find that the judgment is *153 consonant with the letter of the law in all particulars save one.

I. BACKGROUND

Liability is conceded, as is the nature and extent of Heather Reilly’s injuries. See Reilly I, 665 F.Supp. at 980. Nevertheless, we deem it useful to summarize succinctly the underlying facts (borrowing heavily from the district court’s opinions) and delineate the travel of the case.

A. What Transpired. On December II, 1984, Peter Reilly was on active duty with the Navy. On that date, a gravid Donna Reilly was admitted to Newport Naval Hospital. After some six hours in labor, the electronic monitor indicated a dramatic deceleration in fetal heart rate. The district court found, supportably, that this development should have signalled the obstetrician to perform a caesarean section immediately because the baby was in danger of asphyxiation. Id. at 979. The physician instead removed the monitor and insisted on undertaking a vaginal delivery, thereby delaying the birth. When the delivery was eventually performed, it required the application of a vacuum/suction instrument to the baby’s head. The departure from prudent professional standards was palpable.

As a result of the doctor’s manifest negligence, Heather Reilly was born with severe, apparently irremediable, brain damage. The district court determined, sadly but accurately, that she was left “a helpless individual, ‘significantly delayed developmentally’ and unable to see; she will never be able to walk, talk, feed or take care of herself in any way.” Id.

B. Travel of the Case. Heather’s parents filed an administrative claim with the Navy on May 7, 1985 in the amount of $10,000,000. When the matter was not definitively resolved within six months next following, suit was brought under the FTCA. 1 The administrative claim was never amended.

Plaintiffs’ complaint sought damages for Heather’s grievous injuries and losses consequent thereto (including future-care expenses and deprivation of earning capacity). Mr. & Mrs. Reilly also sued for emotional distress and loss of love, society, and affection. See Reilly I, 665 F.Supp. at 983. After discovery was completed, a 7-day bench trial ensued. Both sides introduced expert testimony as to the calculation of damages for lost earning capacity. Appel-lees also supplied expert testimony regarding expenses for Heather’s future care, but “the government presented almost no factual argument against the necessity for and pecuniary valuation of the[se] itemized damages.” Id. at 1000. The trial came to a halt on November 26, 1986 — but, as matters turned out, more evidence was to be taken at supplementary hearings.

During the interval between the trial and the resumed hearings, the district judge attempted to enlist an economist to assist him in respect to certain technical aspects pertinent to the calculation of a damage award. Reilly II, 682 F.Supp. at 152. He approached several potential candidates. Id. at 152-53. Professor Feldman, an economist at Brown University, disqualified himself because he had previously discussed the case with the plaintiffs’ lawyer; others were contacted and one agreed to serve. Id. The judge did not inform counsel of his search. By happenstance, the government learned of it when an assistant United States Attorney (AUSA), in an apparent effort to prepare for the supplementary hearings, called Professor Feldman. The academician forthrightly informed the AUSA that he had already worked on the case at the behest of plaintiffs’ lawyer, and mentioned in passing that he had also been contacted by the judge.

The AUSA immediately requested a chambers conference. The session was held on April 10, 1987. The district judge recounted his conversations with the economists and made no bones about his intent *154 to hire one as a technical advisor. He informed all counsel that he had already contacted the Administrative Office of the United States Courts (AO) to this end, and that he was awaiting approval from the Chief Judge of the First Circuit. 2 The government voiced no contemporaneous objection to the procedure, did not ask the name of the economist whom the court intended to retain, did not ask that either the court’s instructions to the expert or the expert’s advice be reduced to writing, and did not request an opportunity to question him.

To make a tedious tale tolerably terse, the approvals were forthcoming, see Reilly II, 682 F.Supp. at 154-55 & n. 1, and the judge appointed Dr. Arthur Mead of the University of Rhode Island to act as a technical assistant to the court. The judge had two short conferences with Dr. Mead in the spring of 1987. During the same time frame, the court conducted supplemental evidentiary hearings on April 16 and May 5, 1987. On July 28, an opinion and order was issued awarding Heather Reilly $1,000,000 for pain and suffering, $1,104,641 for lost earning capacity, and $8,933,323 in respect to anticipated future care. Reilly I, 665 F.Supp. at 1008. The judge reserved the claims concerning the Reillys’ emotional distress and loss of spousal and parental consortium, and certified the underlying state-law questions to the Rhode Island Supreme Court. 3

The government moved for a new trial, amending its motion in December 1987 to add Dr. Mead’s service as a further basis for relief. The motion was denied by the district court in an erudite opinion concerned exclusively with the court’s engagement of a technical advisor. Reilly II, 682 F.Supp. 150. The court regarded all of the other grounds asserted in the motion as a rehash of arguments previously made and rebuffed. Id. at 151.

It is against this backdrop that we proceed to ponder the orthography of appellant’s alphabet of error.

II. APPOINTING A TECHNICAL AD-VISOR

The United States concedes that a district court has inherent authority to appoint an expert as a technical advisor. 4 See, e.g., Appellant’s Brief at 22-23 n. 17; Reply Brief at 1. It maintains, notwithstanding, that (1) such power is strictly circumscribed *155 by Fed.R.Evid. 706(a), 5 a rule whose protocol the district court saw no need to obey; (2) the court abused its discretion in appointing an advisor at all in this case; (3) the court’s appointee far exceeded the limited role of a technical advisor; and (4) the absence of meaningful procedural safeguards rendered utilization of the advisor fundamentally unfair. We examine these points seriatim.

A. Rule 706.

Throughout its text, Fed.R.Evid. 706 refers not to “experts” generally, but to a more exclusive class: “expert witnesses.” Because the plain language of a Civil Rule is the most reliable indicator of its meaning, we are constrained to conclude that the grasp of Rule 706 is confined to court-appointed expert witnesses; the rule does not embrace expert advisors or consultants. Accord Reed v. Cleveland Bd. of Educ., 607 F.2d 737, 746 (6th Cir.1979); of. National Organization for the Reform of Marijuana Laws v. Mullen, 828 F.2d 536, 545-46 n. 7 (9th Cir.1987) (phrase “court-appointed experts” in 28 U.S.C. § 1920(6), like the counterpart language in Fed.R.Evid. 706, refers only to expert witnesses, not to masters).

This conclusion is buttressed by the text of the advisory committee notes (Notes) accompanying Rule 706. As we read them, the Notes seem geared exclusively to expert witnesses as opposed to technical ad-visors. For example, they cite “expert witness” cases such as Danville Tobacco Ass’n v. Bryant-Buckner Assocs., Inc., 333 F.2d 202, 208-09 (4th Cir.1964) and Scott v. Spanjer Bros., Inc., 298 F.2d 928, 930 (2d Cir.1962), law review articles such as Levy, Impartial Medical Testimony-Revisited, 34 Temp.L.Q. 416 (1961) and Sink, The Unused Power of a Federal Judge to Call His Own Expert Witnesses, 29 S.Cal.L.Rev. 195 (1956), and a compendium of “expert witness” litigation. See Annotation, Trial court’s appointment, in civil case, of expert witness, 95 A.L.R.2d 390 (1964). Read thoroughly, the Notes intimate no attempt whatever to reach the subject of non-testifying experts. They do not mention any case or article dealing with that topic. Given the undeniable fact that, at common law, federal trial courts were empowered not only to designate expert witnesses, e.g., Scott, 298 F.2d at 930, but to appoint technical advisors as well, see, e.g., Ex parte Peterson, 253 U.S. 300, 312-13, 40 S.Ct. 543, 547, 64 L.Ed. 919 (1920) (Brandéis, J.), the omission of any language limitative of the latter power is, we think, telling.

We acknowledge that the question is not free from all doubt. The government, in support of its argument to the contrary, relies on a statement by two respected commentators that “the provisions of ... Rule 706 operate as restrictions on the judge’s common law power to appoint experts.” 3 J. Weinstein & M. Berger, Wein-stein’s Evidence 11706[02] at 706-15 (1988). Yet this statement, we suggest, can — and should — be interpreted to encompass only the appointment of expert witnesses. Indeed, such an interpretation would seem to be contextually indicated, as the very next sentence in the cited text predicts that: “The dissent rather than the majority opinion in a case such as Scott v. Spanjer Bros., Inc. would now prevail.” Id. at 706-15 to -16. In Scott, the dissent argued that the lower court erred in appointing an expert witness without giving reasonable notice to the parties. Scott, 298 F.2d at 932-34 (Hincks, J., dissenting). It distinguished that situation from one involving the trial judge’s inherent power to appoint an auditor — a specie of technical advisor— “whose task it was to organize and report on independent evidence — not to contribute *156 new evidence as does a witness.” Id. at 934. Judge Hincks appears to have thought that the latter circumstance did not necessitate the same sort of notice to the parties. Id. If Rule 706 is, as Wein-stein and Berger say, designed to reverse the holding in Scott and to elevate the dissent into law, then the rule should be construed consistent with Judge Hincks’s view to apply only to expert witnesses and not to those who do not “contribute new evidence.”

The substance as well as the language of Rule 706 comports with this interpretation. The rule establishes a procedural framework for nomination and selection of an expert witness and for the proper performance of his role after an appointment is accepted {e.g., advising the parties of his findings, submitting to depositions, being called to testify, being cross-examined). By and large, these modalities — though critically important in the realm customarily occupied by an expert witness — have marginal, if any, relevance to the functioning of technical advisors. Since an advisor, by definition, is called upon to make no findings and to supply no evidence, see infra Part 11(C), provisions for depositions, cross-questioning, and the like are inapposite. See Hemstreet v. Burroughs Corp., 666 F.Supp. 1096, 1124 (N.D.Ill.1987). 6

The finishing touch is in the caselaw. The United States, despite herculean efforts, has adverted to no reported cases binding the engagement of technical advis-ors with the strands of Rule 706. Without exception, the cases cited by the government for the proposition that the rule “sets out the controlling legal standard pertaining to the court’s appointment of a neutral expert,” Appellant’s Brief at 18, are “expert witness” cases, not “technical advisor” cases. See, e.g., Students of California School for the Blind v. Honig, 786 F.2d 538, 549 (9th Cir.1984), rev’d and remanded on other grounds, 471 U.S. 148, 105 S.Ct. 1820, 85 L.Ed.2d 114 (1985); United States v. Weathers, 618 F.2d 663, 664 (10th Cir.), cert. denied, 446 U.S. 956, 100 S.Ct. 2927, 64 L.Ed.2d 814 (1980); United States v. Green, 544 F.2d 138, 142 (3d Cir.1976), cert. denied, 430 U.S. 910, 97 S.Ct. 1185, 51 L.Ed.2d 588 (1977).

We conclude, therefore, that Rule 706, while intended to circumscribe a court’s right to designate expert witnesses, was not intended to subsume the judiciary’s inherent power to appoint technical advisors. The Civil Rules, after all, were never meant to become the sole repository of all of a federal court’s authority. See HMG Property Investors, Inc. v. Parque Indus. Rio Canas, Inc., 847 F.2d 908, 915 (1st Cir.1988); Brockton Sav. Bank v. Peat, Marwick, Mitchell & Co., 771 F.2d 5, 11 (1st Cir.1985), cert. denied, 475 U.S. 1018, 106 S.Ct. 1204, 89 L.Ed.2d 317 (1986).

B. Abuse of Discretion.

The government’s immediate fallback position is that, even if literal compliance with Rule 706 was not essential, the district court nevertheless abused its discretion in appointing a technical advisor at all. We concur wholeheartedly that such appointments should be the exception and not the rule, and should be reserved for truly extraordinary cases where the introduction of outside skills and expertise, not possessed by the judge, will hasten the just adjudication of a dispute without dislodging the delicate balance of the juristic role. Cf. La Buy v. Howes Leather Co., 352 U.S. 249, 255-57, 77 S.Ct. 309, 313-14, 1 L.Ed.2d 290 (1957) (discussing appropriate occasions for employment of special masters); Reed v. Cleveland Bd. of Educ., 607 F.2d at 747 (similar; use of masters permitted where desirable to “bring[ ] to the court skills and experience which courts frequently lack”).

We wish to emphasize our strongly-held view that the appointment of a technical advisor must arise out of some cognizable judicial need for specialized skills. Appro *157 priate instances, we suspect, will be hen’s-teeth rare. The modality is, if not a last, a near-to-last resort, to be engaged only where the trial court is faced with problems of unusual difficulty, sophistication, and complexity, involving something well beyond the regular questions of fact and law with which judges must routinely grapple. Although a technical advisor can be valuable in an appropriate case, the judge must not be eager to lighten his load without the best of cause.

Despite the fact that the integument as we have shaped it is a narrow one, see supra, we believe that this litigation slips fittingly within it. The ease involved esotérica: complex economic theories, convoluted by their nature, fraught with puzzlement in their application, leading to a surpassingly difficult computation of damages. Future-care expenditures and lost earnings had to be projected over a 70-year period — and for an infant with no proven financial track record. Plaintiffs’ experts differed among themselves on some points. The stakes were demonstrably high. The government was of small help. Its submission on damages, amounting to little more than a lick and a promise, can best be characterized as feeble. The one-sidedness of the evidence itself lent encouragement to the use of a technical advisor to help the court understand the theories which were bruited about. All in all, the litigation was so far outside the mainstream that the judge, in our estimation, had good reason to energize his inherent power to bring a technical advisor on board. Cf. Manual for Complex Litigation, Second (MCL 2d) § 21.54 (1985) (court may consider appointing confidential advisor in “complex litigation” and “when complicated issues are involved”). Mindful of the trier’s discretion in this regard, the charge of abuse simply will not wash.

C. The Technical Advisor’s Role.

Our decision that this was a seemly case for nominating a technical advisor and that the district court was not bound to comply with the requirements of Rule 706 in making the appointment does not end this phase of our inquiry. The government argues that, whatever may be said of the need for the appointment or its mechanics, the district court permitted Dr. Mead to roam far beyond the precincts to which a technical advisor must properly be confined. In the end, the government hints, the judge abdicated the factfinding function in favor of Dr. Mead, relying on him to resolve the merits. We find that the district court’s use of its expert in this case was limited to appropriate technical assistance, and therefore reject the government’s plea.

We start with a restatement of the principle derived from a watershed case anent technical advisors. 7 In Ex parte Peterson, 253 U.S. 300, 40 S.Ct. 543, 64 L.Ed. 919 (1920), the Supreme Court recognized that trial judges in the federal system possessed “inherent power to provide themselves with appropriate instruments required for the performance of their duties,” including the power to “appoint persons unconnected with the court to aid judges in the performance of specific judicial duties, as they may arise in the progress of a cause.” Id. at 312, 40 S.Ct. at 547. See also MCL 2d § 21.54 (indicating that court may appoint confidential advisor in complex litigation). Advisors of this sort are not witnesses, and may not contribute evidence. Similarly, they are not judges, so they may not be allowed to usurp the judicial function. See Kimberly v. Arms, 129 U.S. 512, 524, 9 S.Ct. 355, 359, 32 L.Ed. 764 (1889) (court may not, through appointment of a master or otherwise, “abdicate its duty to determine by its own judgment the controversy presented”); see also MCL 2d § 21.54 (advisors “should not be used to displace the parties’ right to a resolution of disputes through the adversarial system”); cf. La Buy v. Howes Leather Co., 352 U.S. at 256, 77 S.Ct. at 313 (special master’s role *158 is “not to displace the court”). A judge may not, for example, appoint a legal advis- or to brief him on legal issues, since “determination of purely legal questions is the responsibility of the court itself.” Reed v. Cleveland Bd. of Educ., 607 F.2d at 747. Neither may a court employ a technical advisor to “undertake an independent mission of finding facts” outside the record of the case. Johnson v. United States, 780 F.2d 902, 910 (11th Cir.1986) (citation omitted). In fine, the advisor’s role is to act as a sounding board for the judge — helping the jurist to educate himself in the jargon and theory disclosed by the testimony and to think through the critical technical problems.

In this case, it does not appear that the district judge stepped over the line. His description of how he used the advisor is illuminating:

Untrained in the nature and nuances of economic functions, unable to scrutinize the relevance of alleged independent variables or objections thereto, uncertain of the grounds and bounds of valid economic inference, this court recognized its need of a guide to lead it through the maze of economic theory and fact. To this end, [I] decided to adopt the somewhat unusual but not unprecedented procedure of procuring neutral technical advice.

Reilly II, 682 F.Supp. at 152. Put another way, the judge wrote that he needed an expert in-house “to advise and instruct [him] on the myriad and arcane aspects of economic science necessary to a just adjudication of the ... case.” Id. at 155. The judge reported to counsel at a chambers conference that he had explained to Dr. Mead the economist’s role as being to function “in the nature of a law clerk,” Joint Appendix (J.A.) at 568 — someone with whom the judge could engage in “freewheeling discussion.” Id. at 567. Judge Pettine specifically warned the advisor that if in their discourse “anything developed which I feel I want to use which is apart from the briefs, which may go into an area which the briefs did not discuss, ... I am going to feel an obligation to let counsel know.... If they want to question you, that is up to them.” Id. at 569. It is readily apparent that the district court crafted the contours of the engagement with care.

Nor can it validly be argued that the court gave mere lip service to the limitations which it imposed on the advisor’s role. The opinion on the merits indicates plainly that the judge neither relied on evidence supplied by Dr. Mead in reaching conclusions in the case nor deferred unduly to the expert in finding the facts. It takes scant analytic insight to see that the court below rejected the calculations of lost earning capacity proffered by the government’s expert not because of any new facts or theories introduced by the technical advisor, but because the witness’s testimony rested on an inadequate factual and legal basis. See, e.g., Reilly I, 665 F.Supp. at 997. Here, as in Hemstreet, supra, “the [court’s] decision ... was based on the evidence submitted by the parties.” 666 F.Supp. at 1123.

Appellant seeks to convince us that the reverse is true by pointing to the judge’s statement that he sought an expert to assist him in “reconciling the testimony of at least two outstanding experts who take opposite positions.” J.A. 273. This remark, however, proves little. It is, we think, a fair description of what a technical advisor might, with the utmost propriety, undertake. We do not read into it the sinister connotations urged by the government.

A second contention hawked by appellant is more troublesome. The government urges that because Dr. Mead received no written instructions and submitted no written report, it is unclear to what extent the district court may have allowed the boundaries to be overrun. We agree that it would have been better practice to document the interchange between jurist and advisor in some more readily retrievable fashion. Yet we perceive no fatal flaw. In a variety of contexts, we have relied on a judge’s plausible explanation of his orders, findings, and the like. See, e.g., United States v. Metropolitan Dist. Comm’n, 847 *159 F.2d 12, 14 (1st Cir.1988); Lefkowitz v. Fair, 816 F.2d 17, 22 (1st Cir.1987); Advance Fin. Corp. v. Isla Rica Sales, Inc., 747 F.2d 21, 26 n. 10 (1st Cir.1984). Here, the record fully supports the judge’s explanation of how he used Dr. Mead’s services, and the government has offered no cogent reason to doubt this explanation. Just as we have taken cognizance of, and deferred to, the trial judge’s “special role ... in elucidating the meaning and intendment of an order which he authored,” Martha’s Vineyard Scuba Headquarters, Inc. v. Unidentified, Wrecked and Abandoned Steam Vessel, 833 F.2d 1059, 1066-67 (1st Cir.1987), we have complete confidence in the accuracy of Judge Pettine’s recital. Accord Johnson v. United States, 780 F.2d at 910 (district judge’s “outside research” not reversible error because “judge stated he did not rely on those outside sources in reaching his conclusions and this appellate court relies on those representations”).

Appellant’s complaint that it was deprived of any opportunity to cross-examine Dr. Mead appears asthenic. If, as the district court stated, the advisor was not an evidentiary source, there was neither a right to cross-question him as to the economics of the situation nor a purpose in doing so. And, to the extent that it might have profited the government to grill Dr. Mead about his role in the case, the short and simple response is that, after being informed at the April 10 chambers conference that the district court intended to hire a technical advisor, the prosecutors did not ask for written specification of the advis- or’s anticipated role or attempt to reserve a right of inquiry. Even after the verdict was rendered and an objection belatedly interposed to use of the advisor, the government did not move for leave to question him. Having failed to raise that point below, the United States cannot raise it for the first time on appeal. See Aoude v. Mobil Oil Corp., 862 F.2d 890, 896 (1st Cir.1988) (assignment of error untimely where “appellant did not raise the matter below”); Clauson v. Smith, 823 F.2d 660, 666 (1st Cir.1987) (similar; collecting representative First Circuit cases); cf. Johnson v. United States, 780 F.2d at 910 (government’s failure to object to court’s “outside research” during trial constituted procedural default).

In sum, we find the record to be consistent with the district court’s announced employment of Dr. Mead as a technical advis- or. There is, moreover, simply no reasoned basis on which we can conclude that, once he was engaged, the advisor’s performance of his functions strayed beyond the proper ambit of his role. The government’s insistence to the contrary is comprised of little more than self-serving speculation and self-interested surmise.

D. Procedural Safeguards.

Appellant has one remaining shot in its sling. It protests vigorously that, even where a technical advisor may appropriately be engaged by a trial judge outside the realm of Rule 706, fundamental fairness requires that the appointment be hedged about with a panoply of procedural safeguards. Among other things, appellant urges that the district court should have given advance notice to the parties of the expert’s identity and how he was to be used; that written instructions should have been prepared regarding the expert’s duties; and that Dr. Mead should have been required to file a written report. We are quick to acknowledge that these suggestions have some merit.

We think it advisable in future cases that the parties be notified of the expert’s identity before the court makes the appointment, and be given an opportunity to object on grounds such as bias or inexperience. Cf. Hemstreet, 666 F.Supp. at 1124 (technical advisor nominated by parties, who agreed on his independence and expertise). We also think that there is much to commend the preformulation of a written “job description” for the advisor (or in lieu thereof, that the judge deliver comprehensive verbal instructions to the advis- or, on the record, in the presence of all counsel). At the conclusion of his stint, the advisor should file an affidavit attesting to *160 his compliance with the job description. 8 And we do not regard such matters as mere ritual; in an appropriate case, we would not hesitate to reverse if procedural safeguards were wholly inadequate.

Our belief in the value of such prophylactic measures, however, does not avail the government here. On April 10, the district court advised the parties that it had received permission from the paymasters in Washington to employ a technical advisor and that it had staged preliminary discussions with the intended appointee. The government did not inquire as to the expert’s identity or express any objection to the court’s use of an (unknown) expert; indeed, the United States Attorney, himself in attendance at the conference, appeared affirmatively to agree. 9 Nor did the government request that any safeguards be set in place. The record makes manifest that appellant sat back and knowingly acquiesced in the court’s unconditional hiring of an unidentified technical advisor. This was, we think, a waiver. See Johnson, 780 F.2d at 910; see generally Irons v. FBI, 811 F.2d 681, 686 (1st Cir.1987) (describing waiver as “the purposeful relinquishment of an appreciated right” and noting that it “can fairly be deduced from conduct”). Cf., e.g., Wells Real Estate v. Greater Lowell Bd. of Realtors, 850 F.2d 803, 811 (1st Cir.) (argument that trial court should have made preliminary determination waived by failure to request such action below), cert. denied, — U.S. -, 109 S.Ct. 392, 102 L.Ed.2d 381 (1988); Central Progressive Bank v. Fireman’s Fund Ins. Co., 658 F.2d 377, 381-82 (5th Cir.1981) (by failing to protest before jury discharged, party waived objection to special interrogatory that, in retrospect, submitted question of law due to conjunctive phrasing); Nimrod v. Sylvester, 369 F.2d 870, 873 (1st Cir.1966) (plaintiff who sat by when court neglected to answer jury request for supplementary instruction could not complain on appeal; because “unawareness” was “of [counsel’s] own making,” resultant error was waived).

Not only is there waiver here, but it is aggravated by an element of sandbagging. The government, knowing of the court’s plan to consult with a technical advisor, waited to see which way the wind blew. Only when the case turned out disastrously from the government’s viewpoint did appellant decide to voice its litany of concerns about the circumstances of the appointment. The record shows no valid reason why the United States, on April 10 or within a reasonable time thereafter, could not have objected to the hiring of any expert, demanded the name of the court’s candidate, or requested layer upon layer of special swaddling. Certainly, the government has offered us no persuasive reason to explain — let alone excuse — its lassitude. In our view, when a trial judge announces a proposed course of action which litigants believe to be erroneous, the parties detrimentally affected must act expeditiously to call the error to the judge’s attention or to cure the defect, not lurk in the bushes waiting to ask for another trial when their litigatory milk curdles. See Pearson v. Fair, 808 F.2d 163, 166 (1st Cir.1986) (per curiam); cf. James v. Watt, 716 F.2d 71, 77-78 (1st Cir.1983) (upholding denial of motion to amend where plaintiffs waited *161 until they lost their case before making motion), cert. denied, 467 U.S. 1209,
