How has the court considered a motion for attorney fees under section 1021.5?

^4. We note the trial court was familiar with all of the proceedings in the validation action and with the evidence presented. Consequently, it was in a much better position than an appellate court to determine a variety of questions raised by a motion for attorney fees under section 1021.5, including the probabilities relevant to calculating an expected value. (See Chavez v. City of Los Angeles (2010) 47 Cal.4th 970, 991.)
