Two elements of the statute have been subject to the interpretation of the
Supreme Court: who qualifies as a “prevailing party,” and how courts should calculate “reasonable attorney’s fees.”
Prevailing party The Supreme Court has interpreted Section 1988(b) to apply in different ways to prevailing plaintiffs and prevailing defendants. Prevailing plaintiffs ordinarily should receive an attorney's fee award unless the award would be unjust. On the other hand, a prevailing defendant is only awarded fees if the litigation is unreasonable, frivolous, or meritless. The Supreme Court has also clarified in
Buckhannon Board & Care Home, Inc. v. West Virginia Dept. of Health and Human Resources (2001) that to prevail means to obtain a judicial decree on the merits of the case. This means that in order to be eligible for attorney's fees, there must be a court-ordered change in the legal case, or something in the court records that determines a winner.
Lackey v. Stinnie (2025) further clarified that a preliminary injunction does not qualify as a judicial decree, even when the case is
mooted by the challenged law's repeal, because it does not involve a full merits analysis.
Reasonable attorney's fees While the law itself does not explain what is a reasonable fee, both the House and Senate Reports accompanying the Act expressly endorse the analysis set forth in the case
Johnson Highway Express, Inc.
Johnson Highway Express, Inc. identifies 12 factors to be considered in calculating a reasonable attorney's fee: • the time and labor required; • the novelty and difficulty of the question • the skill required to perform the legal services properly; • the preclusion of other employment by the attorney due to acceptance of the case; • the customary fee; • whether the fee is fixed or contingent; • time limitations imposed by the client or the circumstances; • the amount involved and the results obtained; • the experience, reputation, and ability of the attorney; • the "undesirability" of the case; • the nature and length of the professional relationship with the client; and • awards in similar cases.
Hensley v. Eckerhart, , announced certain guidelines for calculating a reasonable attorney's fee under 1988(b), which involved at the basic level the number of hours reasonably expended on the case multiplied by a reasonable hourly rate. In addition, “the fee award should not be reduced simply because the plaintiff failed to prevail on every contention raised in the lawsuit.”
City of Riverside v. Rivera, , affirmed that the amount of damages a plaintiff recovers is certainly relevant to the amount of attorney's fees to be awarded under 1988. It is, however, only one of many factors that a court should consider in calculating an award of attorney's fees. The court rejected the proposition that fee awards under 1988(b) should necessarily be proportionate the amount of damages a civil rights plaintiff actually recovers. The Senate explicitly considered the possibility of a case where there are little or no damages and said that the attorney's fees awarded should “not be reduced because the rights involved may be nonpecuniary in nature.” == Amendments and legislative challenges ==
