Is a plaintiff entitled to an attorney's fee for hours spent on an unsuccessful claim?

Defendant is correct that generally "[w]here the plaintiff has failed to prevail on a claim that is distinct in all respects from his successful claims, the hours spent on the unsuccessful claim should be excluded in considering the amount of a reasonable fee." Hensley v. Eckerhart, 461 U.S. 424, 440 (1983). However, "[w]here a lawsuit consists of related claims, a plaintiff who has won substantial relief should not have his attorney's fee reduced simply because the district court did not adopt each contention raised."
