ministerial officer

if the officer or tribunal possess jurisdiction over the subject-matter upon which judgment is passed, with power to issue an order of process for the enforcement of such judgment, and the order or process issued thereon to the ministerial officer is regular on its face, showing no departure from the law, or defect of jurisdiction over the person or property affected, then, and in such cases, the order or process will give full and entire protection to the ministerial officer in its regular enforcement against any prosecution which the party aggrieved thereby may institute against him, although serious errors may have been committed by the officer or tribunal in reaching the conclusion or judgment upon which the order or process is issued.

One whose duties are purely ministerial, as distinguished from executive, legislative, or judicial functions, requiring obedience to the mandates of superiors and not involving the exercise of judgment or discretion. See U. S. v. Bell (C. C.) 127 Fed. 1002; Waldoe v. Wallace, 12 Ind. 572; State v. Loechner. 65 Neb. 814, 91 N. W. 874, 59 In R. A. 915 ; Reid v. Hood, 2 Nott & McC. (S. C.) 169, 10 Am. Dec. 582
