"To date, no court has refused to recognize a wrongful life claim based upon the recognition that it is unconstitutional to hold that a duty of care is owed to a fetus prior to viability when under Roe v. Wade and its progeny, no duty is owed to a fetus before the fetus becomes viable. Rather, jurisdictions which have decided not to recognize wrongful life claims have done so based on reasoning that focuses on lack of a legally cognizable injury, the impossibility of calculating damages, and/or the lack of causal relationship between the defendant’s conduct and the claimed injury."
