The Unguarded Stairwell: Additional Insured, Exclusive Remedy and the Subcontract Waiver
Delta Builds is general contractor on a Rankin County medical office. Its CGL is an occurrence form with a $1M each-occurrence limit and a $2M general aggregate. The drywall subcontractor, Tri-State, carries $1M CGL and Mississippi workers' compensation, and the subcontract requires Tri-State to name Delta as an additional insured and to waive subrogation against Delta. Tri-State's employee Andre falls from a scaffold and sues Delta, alleging Delta's on-site superintendent left a stairwell unguarded. The scaffold was erected by Tri-State's crew using planks Delta supplied. Andre has collected comp benefits and his medical bills exceed $300,000. Delta has tendered the suit to Tri-State's carrier, which has not responded.
1. Analyze which CGL policies respond to Andre's suit against Delta, and whether the additional insured endorsement is triggered.
Read the worked answer
Both policies are potentially implicated, and the tender should not be withdrawn.
- Delta's own CGL covers Delta's direct negligence through its superintendent. The employer's liability exclusion removes injuries to Delta's own employees, not to another company's worker, so Andre is not excluded.
- Tri-State's CGL responds through the additional insured endorsement. The key question is the causal test: most ongoing-operations additional insured forms (CG 20 10 style) cover liability 'arising out of' the named insured's operations. The immediate negligence was Delta's, but Tri-State's crew erected the scaffold - that is enough nexus in most jurisdictions, since 'arising out of' is read broadly.
- The 'your work' exclusion on Tri-State's policy is a red herring: it bars damage to the insured's own completed work, not bodily injury to a third party.
- Whether Tri-State's policy is primary and non-contributory depends on the endorsement language and on the subcontract's insurance specification. Absent a primary and non-contributory requirement, both policies are primary and share.
Practical step: demand a coverage position in writing and preserve the subcontract's indemnity and insurance provisions as exhibits.
2. Tri-State's carrier argues that workers' compensation immunity bars Andre from suing Delta at all. Assess.
Read the worked answer
Largely wrong, but not frivolous.
The exclusive remedy doctrine runs against the employer - Tri-State. Andre cannot sue his own employer in tort, but a general contractor is a different entity, and an injured worker may pursue third-party claims against those who are not his employer.
The carrier's argument only gains traction through Mississippi's statutory employer / principal contractor doctrine under the Workers' Compensation Act, which can make a principal contractor liable for compensation owed to a subcontractor's employees. Where the contractor has in fact secured comp for that class of workers, it may acquire the employer's immunity. That is a fact-dependent affirmative defense, not an automatic bar, and it requires proof that the subcontract work was part of Delta's trade or business and that comp was secured for those employees.
Delta's superintendent's alleged independent negligence - leaving a stairwell unguarded - is precisely the sort of direct fault that survives immunity analysis in most jurisdictions. Advise Delta to defend on the merits while pleading the statutory employer defense in the alternative.
3. If Delta's CGL pays Andre, does Delta's insurer have subrogation rights against Tri-State?
Read the worked answer
Realistically, no - and the subcontract waiver closes the door further.
- Subrogation is derivative. Delta's insurer succeeds to Delta's rights, and Delta has no tort claim against Tri-State for Andre's injury because Tri-State is Andre's employer and is shielded by the exclusive remedy doctrine. No underlying right, no subrogation.
- The mutual waiver of subrogation in the subcontract independently allocates the risk to insurance. Delta's carrier priced that retention into the account when it underwrote the job and the certificate of insurance.
- The subtler exposure is on the other side: Tri-State's comp carrier may assert a statutory lien against Andre's recovery from Delta. Delta should point to the waiver, though whether a pre-loss contractual waiver defeats a comp carrier's statutory lien is jurisdiction-specific and should be confirmed before relying on it.
Recommendation: obtain an endorsement confirming the waiver on Delta's own CGL, and confirm Tri-State's carrier has recognized the waiver in writing.
