Abney: The 2004 Section 5814 Penalty Rules Reached Earlier Delays Decided Later

By Aneeta Mishra and Timothy Chan

Published May 15, 2026

Abney v. Aera Energy addressed transition rules for Labor Code section 5814 after the 2004 reform legislation changed penalty remedies.

The date of the finding controlled the new remedy

The amended statute applied where the adjudication of unreasonable delay occurred on or after June 1, 2004.

Earlier conduct was not automatically outside the amendment

A delay beginning before the operative date could still be evaluated under the new provision when the finding came later.

Section 5814(c) resolved accrued claims in specified circumstances

The Board applied the amendment’s conclusive-presumption mechanism from its operative date.

The new limitations rule governed later-filed actions

Claims pursued on or after the operative date were subject to the limitations provision added in section 5814(g).

Key takeaways

• Build a timeline of payment, notice, cure, filing, and adjudication.
• Identify which version of section 5814 governs each event.
• Test statutory presumptions and limitations independently.
• Preserve the evidence supporting or rebutting unreasonable delay.
