Does the doctrine of qualified immunity prevent an individual from suing an official in their individual capacity?

7 All defendants were sued in their individual as well as official capacity. The district court ruled that the appellants' action against appellees in their individual capacities was defeated by the application of the doctrine of qualified immunity to these appellees. Although the district court did not directly address appellants' action against appellees in their official capacities, the doctrine of sovereign immunity must be found to have been implicitly applied by the district court. To the extent that appellees were sued in their official capacities, these claims are barred by the doctrine of sovereign immunity. See Gilbert v. DaGrossa, 756 F.2d 1455, 1458-59 (9th Cir.1985).
