In а case reminiscent of Coleridge’s storied seafarer, who was doomed to tell the same tale over and over again, see Samuel T. Coleridge, Rime of the Ancient Manner (1798), plaintiff-appellant Willard Stewart invites us to reexamine, narrow, or distinguish our holding in DiGiovanni v. Traylor Bros., Inc.,
I. BACKGROUND
We divide our depiction of the relevant bаckground into three segments. The facts are mostly undisputed. Consistent with the conventional summary judgment praxis, we take the few controverted facts in the light most flattering to the nonmov-ant (here, the appellant). See McCarthy v. Northwest Airlines, Inc.,
A. The Dredge.
The SUPER SCOOP is a large floating-platform its exact dimensions do not appear in the record equipped with a clam-shell bucket. It operates as a dredgе, removing silt from the ocean floor and dumping the sediment onto one of two scows that float alongside. Once the scows are full, tugboats tow them out to sea and dispose of the dredged material.
Though largely stationary, the SUPER SCOOP has navigation lights, ballast tanks, and a dining area for the crew. Crew members control the clamshell bucket by manipulating a tag-line cable attached to a counterweight. The SUPER SCOOP is incapable of self-propulsion. Crew members use anchors and cables to achieve positional movement at near-glacial speeds. The SUPER SCOOP typically moves once every two hours, covering a distance of thirty to fifty feet. Its scows also lack any means of self-propulsion. Tugboats normally are used to achieve movement. Alternatively, the dredge’s crew drops a bucket from the dredge into one of the scow’s hoppers; by manipulating the cables, the crew then swings the bucket so that it guides the scow around the dredge.
The SUPER SCOOP is classified as an industrial vessel, and as such, it is required to register and comply with safety regulations issued by the Coast Guard and the United States Departmеnt of Transportation. Similarly, the American Bureau of Shipping has issued a load-line certificate to the SUPER SCOOP.
B. The Incident.
Defendant-appellee Dutra Construction Company (Dutra) hired the appellant, a marine engineer, to maintain the mechanical systems of the SUPER SCOOP. Du-tra purposed to use the SUPER SCOOP to help construct an immersed-tube tunnel across the Boston Harbor. The оperational plan called for floating prefabricated tube sections to the site, sinking the tubes into a previously dredged trench, and then covering the sunken tubes with backfill.
The appellant began work in late 1991. The SUPER SCOOP started to dig the cross-harbor trench needed for the tunnel. The process was long and laborious. It was still ongoing on July 15, 1993. On that date, however, the SUPER SCOOP lay idle bеcause one of its scows (Scow No. 4) was out of commission and the other was at sea.
C. The Travel of the Case.
The appellant subsequently sued Dutra in the United States District Court for the District of Massachusetts. One count of his complaint invoked the Jones Act. After a substantial period of pretrial discovery, Dutra moved for summary judgment on all counts. See Fed.R.Civ.P. 56. In due course, the district court, ruling ore terms, denied the motion as to certain counts, but granted brevis disposition on the Jones Act count. This interlocutory appeal follоwed.
II. APPELLATE JURISDICTION
We turn briefly to the threshold issue of appellate jurisdiction. See BIW Deceived v. Local S6,
In civil cases, the usual source of appellate jurisdiction is 28 U.S.C. § 1291 (conferring appellate jurisdiction over “final decisions” of the district courts). Here, however, the order granting partial summary judgment did not dispose of all thе claims asserted. Thus, this court lacks jurisdiction under section 1291. See North Carolina Nat’l Bank v. Montilla,
Withal, there are exceptions to the “final judgnent” rule and one such exception pertains here. Congress, in its wisdom, has enacted a special statute that permits immediate appeals from interlocutory district court orders “determining the rights and liabilities of parties to admiralty cases in which apрeals from final decrees are allowed.” 28 U.S.C. § 1292(a)(3). Thus, an interlocutory order in an admiralty case can be appealed immediately so long as it conclusively determines the merits of a particular claim or defense. Martha’s Vineyard Scuba Headquarters, Inc. v. Unidentified, Wrecked and Abandoned Steam Vessel,
The case at hand satisfies that requirement: thе district court’s order determining, as a matter of law, that the SUPER SCOOP was not a vessel in navigation within the purview of the applicable Jones Act jurisprudence (and that, therefore, the appellant had no cognizable claim under that statute) plainly implicates section 1292(a)(3). Accordingly, we have jurisdiction to hear and determine this appeal.
III. THE MERITS
Having reachеd the merits, we first frame the issue. We then group the appellant’s arguments and address them under two headings.
A. Framing the Issue.
The Jones Act provides in pertinent part:
Any seaman who shall suffer personal injury in the course of his employment may, at his election, maintain an action for damages at law, with the right of trial by jury....
46 U.S.C. app. § 688(a). Congress enacted this legislation in 1920 to protect sea
Over time, the Court has untangled some of thе doctrinal knots. Although the Jones Act itself does not use the word “vessel,” the Court has placed a gloss on the statute. This gloss clarifies that a prospective plaintiffs status as a seaman (and, therefore, his eligibility to sue under the Jones Act) depends, in the first instance, on his connection to a “vessel in navigation.” McDermott Int’l, Inc. v. Wilander,
In many cases, the deceptively simple question of whether a particular floating object is a vessel in navigation reduces to a question of fact. See Chandris,
A. Stare Decisis.
In attempting to convince us that the district court erred in not deeming the SUPER SCOOP a vessel in navigation for Jones Act purposes, the appellant runs headlong into controlling precedent. Eight years ago, this court, sitting en banc, confronted a case in which a plaintiff had sustained injuries while working aboard the barge BETTY F. We described the barge as follows:
The BETTY F was a barge, 100 feet in length, with a 40 foot beam and a raked bow and stern, and with nautical еquipment, such as navigation and anchor lights. In all respects it met the commonly understood characteristics of a vessel, and, indeed, was inspected by the Coast Guard. It had no means of self-propulsion, except that positional movement could be achieved by manipulating its spud anchors. Its current use was to float at the Jamestown, Rhode Island, bridge, beаring a crane that was being used for bridge construction.... It had been at the Jamestown bridge for a month. It was positioned about the bridge, and moved away from the pilings at night, to prevent damage.
DiGiovanni,
DiGiovanni, whose main responsibility was to handle a tag-line to guide the crane, slipped and fell while standing on the deck of an appurtenant supply barge (which served as a work platform). Id. at 1121. He attempted to sue under various theo
The appellant exhorts us to scuttle the holding of DiGiovanni, denouncing the standard it embodies as impractical, unwise, and inconsistent with the decisions of other courts (including the Fifth Circuit). But our precedent-based system of justice places a premium on finality, stability, and certainty in the law, particularly in the field of statutory construction. See Hubbard v. United States,
We do not pledge this allegiance blindly. We recognize that “stare decisis is neither a straightjacket nor an immutable rule.” Carpenters Local Union No. 26 v. United States Fid. & Guar. Co.,
In Williams, we also noted that on rare occasions a circuit precedent, though not directly overruled or superseded, nonetheless might crumble in the face of compelling authority. See id. We speculated that this might occur, say, when persuasive case law postdating “the original decision, although not directly controlling, nevertheless offers a sound reason for believing that the former panel, in light of fresh developments, would change its collective mind.” Id. We аre dubious that this scenario can ever play out where, as here, a panel of a court finds its path blocked by an earlier decision of the full court. Cf. Ewing v. Williams,
In this case, all roads lead to Rome. DiGiovanni has not been overruled by a higher authority and remains good law. Even if we assume, for argument’s sake, that in some extraordinary circumstance a panel might be warranted in declaring an earlier en banc decision obsolete and refus
C. Other Arguments.
The appellant’s remaining arguments take a different tack. He posits that, even under DiGiovanni, the SUPER SCOOP qualifies as a’ vessel in navigation. This argument depends, in the last analysis, on the appellant’s ability to distinguish the SUPER SCOOP from its DiGiovanni counterpart, the BETTY F. Like the district court, we are unable to discern a meaningful distinction.
To begin with, the appellant claims that the DiGiovanni standard does not apply to the SUPER SCOOP at all because that standard only applies to “barges or other floats.” DiGiovanni,
In the first place, when the Di-Giovanni court spoke of “floats,” that word was meant to encompass a wide variety of objects. Surely, a dredge falls within its sweep. To read DiGiovanni more narrowly, as the appellant urges, would strip the en banc court’s holding of all practical meaning.
In the second place, the term “vessel in navigation,” as it has been employed in the Jones Act context, is a term of art. Jones Act recovery hinges not on the physical characteristics of a structure or on how others might view it, but, rather, on the structure’s function and use. Thus, in DiGiovanni, the court refused to place decretory significance on maritime classifications or equipage. See id. Indeed, the DiGiovanni dissent made exactly the same sort of plea that the appellant makes here, see id. at 1124-25 (Torruella, J., dissenting), and the full court nonetheless held the BETTY F not to be a vessel in navigation for Jones Act purposes.
The appellant next notes that, according to the DiGiovanni court, a barge or float may be considered a Jones Act vessel if “its purpose or primary business” is navigation or commerce. Id. at 1123. Seizing on this statement, he alleges thаt the SUPER SCOOP qualifies under this rubric. In his view, dredging itself is a form of navigation and transportation; to dredge, the SUPER SCOOP must transport the clamshell bucket and associated equipment across the harbor, and must cause the dredged material to be carried out to sea. He notes, too, that the SUPER SCOOP was situated in the harbor at the time of the accident, had a captain and a crew (but nо shoreside employees), and carried navigational equipment.
This construct distorts the functional analysis that we endorsed in Di-Giovanni. That analysis focuses on primary functions and, at bottom, dredging is primarily a form of construction. Any navigation or transportation that may be required is incidental to this primary function. In this respect, the only real 'distinction between the SUPER SCOOP and the
The appellant has one last fallback position. He maintains that even if the SUPER SCOOP was not a vessel in navigation, Scow No. 4 the structure on which he was working when the accident occurred was a vessel in navigation because it was actually in transit at that time. Building on this foundation, he argues that since Scow No. 4 was part of the SUPER SCOOP’s flotilla, liability under the Jones Act should attach.
This argument, too, is targeted at an exception to the rule laid down in Di-Giovanni. There, we recognized that, even if a floating structure’s primary purpose was not navigational, workers nonetheless might be considered seamen within the contemplation of the Jones Act if the structure “is in actual navigation or transit” at the time an injury occurred. Di-Giovanni,
First and foremost, the appellant’s status as a seaman depends upon the movement vel non of the SUPER SCOOP, not the incidental positioning of an appurtenant scow. The determinative factor in this equation is that the appellant was assigned permanently to (i.e., was part of the crew of) the SUPER SCOOP, not Scow No. 4. See Bennett,
In an effort to sail around this obstacle, the appellant asseverates that we should attach significance to Scow No. 4’s movement at the time of the accident because the scow was a part of the SUPER SCOOP’s flotilla. This asseveration misconstrues Supreme Court precedent. The Court has held that a plaintiffs relationship to a fleet of vessels, rather than to a particular ship, can establish the connection needed to confer seaman status. ' Harbor Tug & Barge Co. v. Papai,
IV. CONCLUSION
We need go no further. Given the on-point precedent established by the en banc court less than a decade ago and the absence of any trialworthy issue of material fact, the SUPER SCOOP is not a “vessel in navigation” аs that term has developed in the jurisprudence of the Jones Act. Consequently, the lower court appropriately jettisoned the Jones Act count.
Affirmed.
Notes
. In fact, there are two appeals before us but the second is from the district court's denial of a rehearing. Because it adds nothing to the dimensions of the case, we proceed as if the appеllant had filed only an appeal from the entry of the order granting partial summary judgment.
. In Williams, we also spoke of a subsequent decision of the court itself, sitting en banc.
. Like the SUPER SCOOP, the BETTY F possessed "the commonly understood characteristics of a vessel”; for instance, it was registered with the Coast Guard, obliged to comply with various safety regulations applicable to ships, and had navigation lights, ballast tanks, and the like. See DiGiovanni,
