In April 2008, Carroll granted in part and denied in part a motion for summary judgment by a group of Latino professors at Maricopa Community College, who had objected to their college's failure to discipline a math professor who distributed emails containing multiple racially charged and politically incorrect statements about immigration. In May 2010, a 3-judge panel of the 9th Circuit Court of Appeals overturned the judge's ruling, holding that academic freedom protected the right of the math professor to speak his mind on controversial issues.
