These rules are not suspended in cases where conclusions must be drawn from agreed or uncontradicted facts. In such instances, “[e]ven ... where elusive concepts such as motive or intent are at issue, summary judgment may be appropriate if the non-moving party rests merely upon conclusory allegations, improbable inferences, and unsupported speculation.” Medina-Munoz v. R.J. Reynolds Tobacco Co., 896 F.2d 5, 8 (1st Cir.1990). The outcome depends upon the cogency of the conclusion which the movant asks the court to draw. When, as in the case before us, only a single conclusion is plausibly inferable from the uncontradicted facts, Rule 56 can properly be invoked. See, e.g., Oliver v. Digital Equip. Corp., 846 F.2d 103, 109 (1st Cir.1988); Binkley Co. v. Eastern Tank, Inc., 831 F.2d 333, 337 (1st Cir.1987).
III. THE MERITS
Plaintiff, as if bent on out-heroding Herod, see generally W. Shakespeare, Hamlet, Act III, sc. ii (1601), harangues stridently that brevis disposition of his complaints contravened both the general purposes of Title III and the specific rationale behind the statute’s consent exception. Turning up the volume, however, cannot mask the paucity of content contained in plaintiffs argumentation.
A. The Law.
Although plaintiff repeatedly declaims that wire communications are “protected absolutely from illegal interception,” that rallying cry — like most sloganeering — overstates the proposition. Title III was intended to prohibit all interceptions “except those specifically provided for in the Act.” United States v. Giordano, 416 U.S. 505, 514, 94 S.Ct. 1820, 1826, 40 L.Ed.2d 341 (1974). Congress, in its wisdom, chose to insert a myriad of exceptions and restrictive definitions into Title III, purposely leaving certain wire communications unprotected. See, e.g., 18 U.S.C. § 2511(1) (prohibiting intentional interception and disclosure “[ejxcept as otherwise specifically provided”); see also Camacho v. Autoridad de Telefonos de Puerto Rico, 868 F.2d 482, 489 (1st Cir.1989) (discussing some types of legal interceptions); United States v. Axselle, 604 F.2d 1330, 1334 (10th Cir.1979) (Title III outlaws only “willful” intercepts). Accordingly, there is little to be gained by pejorative declamations; the question is simply whether a particular intercept runs afoul of the statute’s imperatives.
18 U.S.C. § 2511(2)(d),
supra note 4, outlines a Title III exclusion applicable “where one of the parties to the communication has given prior consent to such interception....” We agree with the Second Circuit that “Congress intended the consent requirement to be construed broadly.”
United States v. Amen, 831 F.2d 373, 378 (2d Cir.1987). In this spirit, we — and other courts — have held that Title III affords safe harbor not only for persons who intercept calls with the explicit consent of a conversant but also for those who do so after receiving implied consent.
See United States v. Willoughby, 860 F.2d 15, 19 (2d Cir.1988),
cert. denied, — U.S. —, 109 S.Ct. 846, 102 L.Ed.2d 978 (1989);
Amen, 831 F.2d at 378;
Watkins v. L.M. Berry & Co., 704 F.2d 577, 581 (11th Cir.1983);
Campiti v. Walonis, 611 F.2d 387, 393 (1st Cir.1979). Acknowledging the doctrinal vitality of implied consent, however, does not address its parameters — nor can we suggest any pat, all-purpose definition. In the Title III milieu as in other settings, consent inheres where a person’s behavior manifests acquiescence or a comparable voluntary diminution of his or her otherwise protected rights.
Cf., e.g., United States v. Garcia-Rosa, 876 F.2d 209, 217-18 (1st Cir.1989) (discussing consent in fourth amendment context),
cert. denied, — U.S. —, 110 S.Ct. 742, 107 L.Ed.2d 760 (1990);
Pan Eastern Exploration Co. v. Hufo Oils, 855 F.2d 1106, 1126-27 (5th Cir.1988) (discussing consent re doctrine of conversion);
Calderon Rosado v. General Elec. Circuit Breakers, Inc., 805 F.2d 1085, 1087 (1st Cir.1986) (discussing consent under Civil Rules); 17 C.J.S.
Contracts § 132 (1955); 86 C.J.S.
Torts § 12 (1955).
Of course, implied consent is not constructive consent. Rather, implied con
