By his complaint plaintiff in effect seeks to rescind his resignation pursuant to Civil Code, section 1689, on the ground that his consent had not been real or free within the meaning of Civil Code, section 1567, but had been obtained through duress, menace, fraud, undue influence, or mistake. A pleading under these sections is sufficient if, stripped of its conclusions, it sets forth sufficient facts to justify legal relief. (Gogerty v. Coachella Valley Junior College Dist., 57 Cal.2d 727, 731 [21 Cal.Rptr. 806, 371 P.2d 582]; Krug v. Meeham, 109 Cal.App.2d 274, 277 [240 P.2d 732].) In our view the facts in the amended complaint are insufficient to state a cause of action for duress, menace, fraud, or mistake, but they do set out sufficient elements to justify rescission of a consent because of undue influence. We summarize our conclusions on each of these points.
