Rivera and Crump: The Section 4650 Penalty Does Not Attach to Lump-Sum Proceeds

By Aneeta Mishra and Timothy Chan

Published September 13, 2026

Rivera and Crump consolidated two disputes over whether Labor Code section 4650(d)'s automatic increase reaches benefits converted into lump-sum payments.

The cases involved commutation and settlement proceeds

Rivera concerned a commuted permanent-disability award, while Crump concerned death benefits resolved through a compromise and release.

Section 4650 addresses periodic indemnity

The Board read the statutory timing rules as governing recurring temporary- and permanent-disability installments.

Conversion to a lump sum changed the payment character

Once benefits were commuted or settled for a single amount, the proceeds were no longer payments due on the periodic schedule described by section 4650.

Other delay consequences remained analytically separate

The decision distinguished the automatic section 4650(d) increase from issues such as interest and an unreasonable-delay penalty under section 5814.

Key takeaways

• Identify whether the overdue obligation is periodic indemnity or a lump sum.
• Separate section 4650(d), interest, and section 5814 theories.
• Track the approval order and the actual payment due date.
• Preserve the payment ledger and the character of each component.
