"Well-settled is the rule that good faith is always presumed and the Chapter on Human Relations of the Civil Code directs every person, inter alia, to observe good faith which springs from the fountain of good conscience. Specifically, a public officer is presumed to have acted in good faith in the performance of his duties. Mistakes committed by a public officer are not actionable absent any clear showing that they were motivated by malice or gross negligence amounting to bad faith. ‘Bad faith’ does not simply connote bad moral judgment or negligence. There must be some dishonest purpose or some moral obliquity and conscious doing of a wrong, a breach of a sworn duty through some motive or intent or ill will. It partakes of the nature of fraud. It contemplates a state of mind affirmatively operating with furtive design or some motive of self-interest or ill will for ulterior purposes." (Collantes v. Marcelo, 556 Phil. 794, 806 [2007].)
