Does the doctrine of qualified immunity apply to a government official who is accused of making a mistake of law, error of law or error of fact?

protection of qualified immunity applies regardless of whether the government official makes an error that is "a mistake of law, a mistake of fact, or a mistake based on mixed questions of law and fact." Pearson v. Callahan, 555 U.S. 223, 231 (2009) (internal quotation and citation omitted). "The principles of qualified immunity shield an officer from personal liability when an officer reasonably believes that his or her conduct complies with the law." Id. at 245.
