The Scindia Duty to Intervene: When a Vessel Owner Has to Step In

The Short Answer

The third of the three duties a vessel owner owes under Scindia Steam Navigation Co. v. De Los Santos is the duty to intervene. It is the narrowest of the three duties and applies in a specific factual scenario: a hazard develops during the contractor's work, the vessel owner becomes aware of it, and the contractor — exercising what the courts call "obviously improvident judgment" — intends to continue the work anyway. In that situation, the vessel owner is required to step in, warn workers, halt the operation, or otherwise act to prevent the foreseeable injury.

The duty is rarely the primary theory in a §905(b) case. The turnover duty handles conditions that existed before the work began; the active control duty handles ongoing situations where the vessel owner has remained involved or retained control. The duty to intervene fills a narrow gap between them — situations where the hazard arose after turnover and outside the vessel owner's control, but the vessel owner learned of it and saw the contractor preparing to ignore it. When the gap is real, the duty applies.

The Duty to Intervene at a Glance

The vessel owner has a duty to intervene when both of these conditions are met:

1. The vessel owner has actual knowledge of a hazard during the contractor's operations.
2. The vessel owner has actual knowledge that the contractor, in the exercise of obviously improvident judgment, intends to proceed with the work in the face of the hazard — and therefore cannot be relied on to remedy it.

When both conditions are met, the vessel owner must intervene. Failure to intervene supports liability under §905(b). The duty is significantly narrower than the turnover or active control duties because it requires actual knowledge — not constructive knowledge, not what a reasonable inspection would have revealed — of both the hazard and the contractor's obviously improvident decision to ignore it.

What §905(b) and Scindia Set Up

Section 905(b) of the Longshore and Harbor Workers' Compensation Act preserves a covered worker's right to sue the vessel owner for negligence even though the Act's exclusive-remedy provision bars suits against the direct employer. Scindia Steam Navigation Co. v. De Los Santos, 451 U.S. 156 (1981), defined what a vessel owner's negligence duty actually means in that context. The opinion set out three distinct duties: the turnover duty, the active control duty, and the duty to intervene.

The default rule, central to Scindia, is that the vessel owner has no general obligation to inspect or supervise the contractor's operations once turnover is complete. The vessel owner is entitled to rely on the contractor's professional judgment and experience. The active control duty is the principal exception to that default — it applies when the vessel owner stays involved in or retains control over the work. The duty to intervene is a secondary exception. It applies when, despite no active involvement, the vessel owner learns of a specific hazard and learns that the contractor is going to proceed anyway in obviously improvident judgment.

The narrower scope of the duty to intervene reflects the rule it carves out from. Scindia wanted the vessel owner to be able to rely on the contractor's expertise; the duty to intervene applies only when that reliance has become unreasonable because the vessel owner has affirmatively learned that the contractor is going to make a clearly bad decision.

The Two-Part Test

The Fifth Circuit's clearest statement of the duty appears in Randolph v. Laeisz, 896 F.2d 964, 971 (5th Cir. 1990): the duty to intervene requires (1) knowledge of the hazard and (2) knowledge that the contractor, in the exercise of obviously improvident judgment, means to work on in the face of it and therefore cannot be relied on to remedy it.

Each element does real work.

Element 1: Actual Knowledge of the Hazard

The knowledge requirement is actual knowledge, not constructive knowledge. The duty to intervene is not breached because the vessel owner should have known about a hazard. It is breached because the vessel owner actually knew about it and didn't act.

This is a meaningful narrowing. The turnover duty extends to defects the vessel owner would have known of through reasonable inspection. The active control duty can attach to conditions that would be apparent to someone exercising the kind of oversight that retained control implies. The duty to intervene does not. The plaintiff has to prove the vessel owner actually knew.

Knowledge can be proven by direct evidence — a complaint to a vessel-owner employee, an incident report, a logbook entry, an email — or by circumstantial evidence sufficient to support the inference. But the inference is not automatic from facts that should have alerted the vessel owner. The required finding is that the vessel owner did, in fact, know.

Element 2: Obviously Improvident Judgment

The second element is the harder one in most cases. The vessel owner must know not only of the hazard but also that the contractor intends to continue working in the face of it and that the contractor's decision to do so is "obviously improvident."

"Obviously improvident" is not the same as "negligent" or "unreasonable." The Fifth Circuit has used the phrase to signal that the contractor's decision must be clearly wrong in a way that a vessel owner observing it would recognize as such. A contractor making a borderline judgment call doesn't trigger the duty. A contractor proceeding in the face of a hazard that any reasonable vessel owner would see as a serious problem does.

The element is meant to preserve the Scindia default of vessel-owner reliance on the contractor's expertise. The vessel owner doesn't have to second-guess every decision. The vessel owner has to step in only when the contractor's decision has become obviously bad — at which point the reliance the default protects is no longer reasonable.

How Courts Have Actually Applied the Duty to Intervene

The duty produces relatively few reported decisions on its own, but the recurring patterns are recognizable.

Hazards reported to the vessel and ignored. When a contractor's worker reports a hazard to the vessel owner — through the captain, a vessel-owner supervisor, or any other channel — and the vessel owner takes no action while the contractor's work proceeds, the duty to intervene is squarely implicated. The actual-knowledge element is satisfied by the report itself. The obviously-improvident element depends on whether continuing the work was clearly wrong given what the report disclosed.

Hazards observed by the vessel's crew. When the vessel's own crew sees a problem during the contractor's operations — a piece of equipment failing, a procedure being performed unsafely, a worker placed in a foreseeable danger zone — and the crew tells the vessel owner nothing while the work continues, the duty applies if the vessel owner is appropriately charged with what its crew observed. The doctrine treats the vessel owner's organizational knowledge as the knowledge of the crew acting in the scope of employment.

Hazards documented in the vessel's records. Logbook entries, incident reports, near-miss documentation, safety meeting minutes — anything that records the existence of a hazard known to the vessel owner before the injury — supports actual knowledge for the duty-to-intervene analysis. Defense efforts to characterize these records as "routine" or "administrative" often fail. The documents speak to what the vessel owner knew.

The obviously-improvident threshold. The Fifth Circuit and other courts have generally required that the contractor's decision to proceed be clearly bad, not merely debatable. A contractor making a defensible call about how to handle a difficult situation does not put the vessel owner on the hook to intervene. A contractor pushing workers into a known hazard without any reasonable justification does.

What This Means If You Were Hurt

The duty to intervene is rarely the only theory in a §905(b) case, but it can be the decisive one in particular fact patterns. A few practical points:

1. Document who knew and when. The actual-knowledge element is often the central battlefield. Anything in writing that puts the vessel owner on notice of the hazard — a report, an email, a log entry, a safety-meeting record — matters. So does testimony about verbal reports to the vessel's officers or to vessel-owner supervisors.

2. The duty is rarely your only theory. The duty to intervene is typically pleaded in the alternative to the turnover duty (for conditions that existed at turnover) and the active control duty (for situations where the vessel owner stayed involved). Plaintiffs usually plead all three. Losing on one doesn't matter if a parallel theory carries.

3. The duty bridges the gap between the other two. Sometimes the strongest argument is that the hazard developed during operations (so the turnover duty is weaker), the vessel owner wasn't actively controlling the area (so the active control duty is weaker), but the vessel owner clearly learned of the hazard and saw the contractor going forward anyway. That is the duty-to-intervene scenario.

4. The vessel owner's knowledge is provable through ordinary discovery. Logs, emails, incident reports, supervisor testimony, crewmember depositions — all the things a §905(b) case develops in the ordinary course. The "actual knowledge" requirement is meaningful but it is not insurmountable. Cases where the vessel owner actually knew tend to leave evidence.

5. "Obviously improvident" is a fact-intensive standard. Whether the contractor's decision to proceed was obviously bad is the kind of question juries decide. Summary judgment on the duty to intervene is appropriate only when the evidence allows no reasonable disagreement. In contested cases, the question goes to a jury.

How the Duty to Intervene Connects to the Other Two Scindia Duties

The three Scindia duties cover different points in the work and different categories of hazard.

• The turnover duty addresses the condition of the vessel at the moment of turnover. It includes defects the vessel owner knew or would have known through reasonable inspection. The "open and obvious" defense is available against it.
• The active control duty addresses ongoing operations where the vessel owner has retained or assumed control — through active involvement, retained equipment or areas, or custom/contract. The "open and obvious" defense is not available against it.
• The duty to intervene addresses the narrower scenario of a hazard arising during operations, in an area the vessel owner does not actively control, where the vessel owner gains actual knowledge of the hazard and of the contractor's obviously improvident intent to proceed.

The three duties are not mutually exclusive. A particular injury may implicate one, two, or all three. Plaintiffs typically plead all three theories in the alternative; defendants typically focus their summary judgment briefing on the duty most vulnerable to attack (often the turnover duty, where open-and-obvious is available). The plaintiff's job is to keep the alternatives alive — losing on one duty doesn't matter if another duty independently supports liability.

When the Case Has More Than a Duty-to-Intervene Fight

A clean duty-to-intervene claim — where the vessel owner clearly knew of a hazard, the contractor was clearly going to proceed despite it, and the contractor's decision was clearly bad — is unusual. Most §905(b) cases involve a duty-to-intervene theory pleaded alongside one or both of the other two Scindia duties.

When a duty-to-intervene theory runs alongside other complications — a foreign-flagged vessel that triggers personal-jurisdiction analysis, an injury on the Outer Continental Shelf that brings OCSLA situs questions, a contested seaman-status finding that determines whether §905(b) or the Jones Act governs, or a forum-selection clause attempting to send the case offshore — the §905(b) briefing has to coordinate with the rest of the case.
