Though in the past, federal circuit courts — when reviewing denial of benefits cases governed by ERISA — used to defer to the decisions made by the plan administrator (pursuant to the “abuse of discretion” standard), the law in many states has since changed significantly.
Many states have prohibited the use of discretionary provisions (transferring responsibility for claims handling and determinations from plan administrators to insurers).
In these states, ERISA jurisprudence now requires that the court review the denial of benefits decision in accordance with the “de novo” standard, which requires that the court review the denial of benefits as if no prior decision had been made (pertaining to the facts at-issue).
By reviewing denial of benefits claims de novo, the court empowers ERISA beneficiaries to a significant degree — you must present the facts that support your claim, and the court will evaluate whether you should have received benefits in accordance with the language/terms of the applicable plan.
