What are the elements of constructive fraud and fraudulent concealment?

In the case of constructive fraud and fraudulent concealment, the two showings are controlled by elements common to fraud claims. Broadly speaking, "there are two causation elements in a fraud cause of action. First, the plaintiff's actual and justifiable reliance on the defendant's misrepresentation must have caused him to take a detrimental course of action. Second, the detrimental action taken by the plaintiff must have caused his alleged damage." (Beckwith v. Dahl (2012) 205 Cal.App.4th 1039, 1062.)
