So I am reviewing for my civ pro final and I am still a bit confused about long arm statutes and when they are needed to establish PJ over non-residents. My professor says that even when there is minimum contacts and fairness/reasonableness satisfied you still need to see if the state's long arm statutes would reach the D, is this true? Also, my professor said that even when non-resident D is in the state voluntarily (i.e. like Burnham) and he has been served, you still have to consider the long arm statute. Is this correct? Thanks.
