Rambo I: Increased Earning Capacity Could Support Modification Without Physical Improvement

Published August 13, 2026

Metropolitan Stevedore Co. v. Rambo concerned a longshore worker who received a permanent-partial-disability award after back and leg injuries, then acquired new skills and earned substantially more while his physical impairment remained unchanged.

The original award measured lost earning capacity

John Rambo stipulated to a permanent partial disability and a weekly wage loss. The employer paid the first 104 weeks, after which the Longshore Act special fund bore continuing liability.

New skills changed the worker’s economic position

After the award, Rambo attended crane school and obtained better-paid work as a crane and heavy-lift operator. His postaward wages greatly exceeded his preinjury earnings even though his physical condition had not improved.

Change in conditions included economic change

Section 22 permits modification based on a change in conditions or a factual mistake. The Court rejected a physical-change-only reading because disability under the Act is an economic concept tied to capacity to earn wages as well as medical condition.

The case returned for the statutory wage-capacity inquiry

The Court reversed and remanded so the agency could determine whether the higher actual wages fairly represented Rambo’s earning capacity. Later proceedings and current Longshore Act doctrine must be checked before applying the principle to a new record.

Key takeaways

• Compare preinjury wages, postinjury earnings, skills, and available work.
• Separate medical impairment from the statutory measure of earning capacity.
• Document whether actual earnings fairly represent sustainable capacity.
• Use section 22 procedures and timing rules for any modification request.
