Wife is suing for loss of consortium for her husband’s injuries, and now wants to add her own personal injuries as a claim. This is TN case. We have the discovery rule in TN which says the SOL doesn’t start running until the plaintiff knows or should have known of the injury.  Test for TN is whether the amendment raises a new cause of action and not related back (v. Fed rules).  This passes the federal test for amendment, but not TN’s because TN said this was a new cause of action.  You have to pass both tests in order to get the amendment.
