Daniel Arceneaux, Louis Daverede, Jr., Vives Lemmon and Jules Menesses v. Amstar Corp., Amstar Sugar Corp., Tate and Lyle North American Sugars, Inc., and Domino Sugar Company
200 So. 3d 277
La.2016Background
- Plaintiffs (Barbe and Waguespack groups) sued American Sugar for occupational hearing loss allegedly from workplace noise exposure spanning 1941–2006; Continental issued occurrence-based CGL policies only for portions of that period (1963–1978) and had coverage for bodily injury only from Dec. 31, 1975–Mar. 1, 1978.
- Policy language: insurer "shall have the right and duty to defend any suit ... for bodily injury" where "bodily injury ... occurs during the policy period."
- American Sugar sought a full defense from Continental; Continental agreed to pay 25% of defense costs but reserved rights and disputed an obligation to provide a complete defense given gaps in coverage.
- Trial court ordered Continental to provide a complete defense going forward; Fourth Circuit affirmed. Louisiana Supreme Court granted review to decide whether the duty to defend can be prorated in long-latency exposure cases when policies cover only part of the exposure period.
- The court framed the question as one of contract interpretation and insurance-allocation doctrine in long-latency disease litigation (exposure/continuous-trigger theories and competing allocation methods).
- Supreme Court held the duty to defend may be prorated based on policy periods (time on the risk), reversed the trial court, and remanded for calculation of Continental’s pro rata share.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether an occurrence-based insurer's duty to defend is indivisible and requires a complete defense so long as any portion of pleaded claims potentially falls within coverage | American Sugar: policy says insurer must "defend any suit" if pleadings disclose any possibility of coverage; thus duty to defend is complete once triggered | Continental: duty to defend should be prorated when policy covers only part of the exposure period; insured should bear costs for uninsured years | Held: Duty to defend may be prorated in long-latency exposure cases; insurer pays pro rata share tied to its policy periods (time on the risk) |
| Whether defense costs allocation should follow joint-and-several (Keene) or pro rata (Forty-Eight Insulations/Owens-Illinois) method | American Sugar: favors joint-and-several so one triggered insurer cannot shift defense burden to insured for uncovered periods | Continental: favors pro rata allocation to avoid windfalls and require insured to bear uninsured periods | Held: Adopt pro rata allocation for defense costs based on policy language and exposure theory; time-on-risk proration appropriate here |
| Whether adopting pro rata proration violates reasonable expectations of parties or Louisiana law | American Sugar: full defense rule is established and equitable | Continental: proration aligns with policy terms and exposure theory; does not violate expectations or public policy | Held: Proration consistent with contract terms, exposure theory, and public policy concerns about incentivizing continuous insurance |
| Appropriate formula for allocation (time-only vs. limits×time or other factors) | American Sugar: (implicitly) formula should not reduce insurer’s defense obligations once triggered | Continental: time-on-risk is appropriate here given gaps and lack of policy limits for uninsured periods | Held: Use a time-on-the-risk proration formula for defense-cost allocation in this case; remanded to compute Continental’s percentage share |

- Ins. Co. of N. Am. v. Forty-Eight Insulations, Inc., 633 F.2d 1212 (6th Cir. 1980) (applied exposure theory and held defense costs and indemnity should be prorated; insured bears share for uninsured periods)
- Owens-Illinois, Inc. v. United Ins. Co., 650 A.2d 974 (N.J. 1994) (rejected Keene; adopted pro rata allocation and urged formulas considering time on risk and policy limits)
- Cole v. Celotex Corp., 599 So.2d 1058 (La. 1992) (Louisiana adopted exposure theory for long-latency disease; occurrence = exposure during policy period)
- Norfolk S. Corp. v. Cal. Union Ins. Co., 859 So.2d 167 (La. App. 1st Cir.) (allocation under exposure theory and proration among insurers on risk)
