Lawyers for Maricopa County Sheriff Joe Arpaio face a Monday deadline for filing an appellate brief over a ruling that concluded the sheriff's office has systematically racially profiled Latinos in its patrols.
Arpaio has appealed a May ruling by U.S. District Judge Murray Snow that found the sheriff's office has racially profiled and unreasonably prolonged the detentions of people who were pulled over.
The sheriff also has appealed Snow's order last fall that ordered the appointment of an official to monitor the agency to see if it's following the remedies called for by the judge.
Arpaio vigorously denies the racial profiling allegations.
His lawyers are expected to blame federal authorities for providing some of Arpaio's deputies with faulty immigration enforcement training.
