Case assignment is from CourtListener’s PACER-derived docket records: a partial sample, not a complete caseload, reflecting the judge last assigned each case. How we count.
On appeal
Of 78 of Roll’s decisions reviewed on the merits by the U.S. courts of appeals in our data, 62 were affirmed, 12 reversed or vacated, and 4 affirmed in part and reversed in part. This is a historical count of appellate outcomes for cases we could match, not a judgment of the judge, and not a complete record. How we count.
In our data, Roll authored 45 published opinions for the court (1992–2009). Most cited: Yslava v. Hughes Aircraft Co. (44 citations).
A selective record from published opinions in the CourtListener corpus, not every ruling; most unpublished district orders are not included. Counts and rankings are objective and recomputable: how we count. We describe the record, not the judge.
