Can a plaintiff be denied or reduced an attorney's fee award if he fails to prove only nominal damages?

* As the majority opinion points out in another footnote, "nominal damages can be grounds for denying or reducing an attorney's fee award." See Majority Opinion at [page 317, note 5]; see also Farrar v. Hobby, 506 U.S. 103, 115, 113 S.Ct. 566, 575, 121 L.Ed.2d 494 (1992) ("When a plaintiff recovers only nominal damages because of his failure to prove an essential element of his claim for monetary relief, the only reasonable fee is usually no fee at all."
