See, e.g., Spaulding, 102 Iowa at 649, 72 N.W. at 291 (concluding that the treasurer of the commissioners of pharmacy was not a public officer because the position of treasurer “was a creation of the commission ... and at all times subject absolutely to their control”); McKinley, 228 Iowa at 1189-91, 293 N.W. at 451 (concluding that county engineer was an “official” because he furnished a bond and took an oath of office; but more importantly because several statutes defining the powers and duties of the county engineer delegated certain sovereign powers to that position); Whitney, 232 Iowa at 71, 4 N.W.2d at 398 (<HOLDING>); Hutton, 235 Iowa at 56, 16 N.W.2d at 20
