This report discusses asylum and withholding of removal immigration cases, and the application of the "one central reason" rule which dictates that asylum claimants demonstrate that an approved persecution grounds is one of the central reason they are claiming asylum. The same standard has been used in withholding of removal claim cases but a recent ruling by the U.S. Ninth Circuit Court stated that the "one central reason" rule does not apply to withholding of removal cases creating a split in opinion among courts.
