Where a prevailing plaintiff succeeded on only some claims, the court should make a two-part inquiry: “First, did the plaintiff fail to prevail on claims that were unrelated to the claims on which he succeeded? Second, did the plaintiff achieve a level of success that makes the hours reasonably expended a satisfactory basis for making a fee award?  Here, the trial court slashed plaintiff’s fees from the requested $800,000 to $125,000 largely based on its finding that plaintiff’s retaliation claim was unrelated to his discrimination and harassment claims on which he lost.  This decision holds that the trial court’s reasoning and result were an abuse of discretion because it was necessary for plaintiff to prove his discrimination and harassment claims in order to show that he had reason to make the complaint that led to the retaliation.  Evidence of the facts regarding the alleged underlying discriminatory and harassing conduct about which plaintiff had complained was relevant to establish, for the retaliation cause of action, the reasonableness of his belief that conduct was unlawful.
