Surrogates Kill Patient for the Money - Noval v. Kaiser

This Southern California case (Noval v. Kaiser Fdn. Hospital) sadly reads a lot like an old James Spader, Kyra Sedgwick, Helen Mirren movie: Critical Care.  

Hector Noval, the son of a multimillionaire patient alleges that his sisters falsely represented to providers that the father would not want to be hooked to a ventilator - even if just temporarily.  Noval claims that providers failed to perform any due diligence or due care into confirming the veracity of representations made by the sisters.  Moreover, even though Noval was named as a co-agent in the patient's advance directive, he was not kept informed of the decisions that his sisters were making.  Noval discovered, only after his father's death, that his father's death had been prematurely caused by his greedy sisters.
