If you are dealing with an ERISA benefit denial, the words buried in the plan documents can shape almost everything that happens later in court. A few lines about who gets to “interpret,” “decide,” or “determine” eligibility may influence whether a judge takes a fresh look at the claim or gives the plan administrator significant deference.
That is why reading plan language carefully can matter so much.
In this post you’ll learn how courts generally approach the standard of review in ERISA cases, what kinds of phrases often signal discretionary authority, where those phrases usually appear, what red flags to watch for, and why a close reading of the plan may become part of a larger litigation strategy. If you want a broader overview before diving in, this plain-English explanation of how courts review benefit denials gives helpful background.

In ERISA denial cases, the standard of review often affects how much deference a court gives the decision-maker. In Firestone Tire & Rubber Co. v. Bruch, the U.S. Supreme Court explained that a denial of benefits is reviewed de novo unless the plan gives the administrator or fiduciary discretionary authority to determine eligibility or construe plan terms. When that discretionary language is present, a more deferential review may apply. That basic framework remains the starting point in ERISA benefits litigation. Justia’s summary of Firestone describes the rule directly, and the Legal Information Institute’s ERISA materials reflect the same general structure.
In practical terms, de novo review usually means the court examines the dispute without giving built-in deference to the administrator’s interpretation. A deferential standard, often described as abuse of discretion or arbitrary-and-capricious review depending on the circuit, tends to make the administrator’s wording choices in the plan much more important. That is one reason many claim files end up turning on language that looked harmless at first glance.
One of the easiest ways people get tripped up is by reading the wrong document first.
A denial letter might quote plan language, but the real question is usually whether the governing plan documents actually grant discretionary authority. Under ERISA, plans are subject to formal claims-procedure rules, and the Department of Labor explains that these rules impose minimum procedural requirements for employee benefit plans covered by the statute. See the Department of Labor’s claims procedure guidance and the related compliance assistance publication on 29 C.F.R. § 2560.503-1.
When looking for standard-of-review clues, people often examine:
That list matters because not every document carries the same legal weight. In CIGNA Corp. v. Amara, the Supreme Court drew an important distinction between an SPD and the actual plan terms. In general terms, SPDs communicate with participants, but they do not automatically become the plan itself. That can matter a lot where an SPD contains discretionary language, but the controlling plan document does not. The Supreme Court’s discussion in Amara is frequently cited for that point.
