_Other Rights of the States._--Among the other rights of the states under the Federal Constitution may be mentioned the right of equal representation in the senate, a right of which no state can be deprived without its consent, and the right of territorial integrity: no new state may be created within the jurisdiction of another state, nor may any state be formed by the junction of two or more states or parts of states, without the consent of the states concerned. =Obligations and Duties of the States.=--Rights and privileges usually imply obligations, and so we find that the states owe certain duties to one another and to the union of which they are a part, and the harmony and success of the federal system are dependent in a large measure upon the performance of these duties in good faith. _Full Faith and Credit._--First of all, each state must give full faith and credit to the acts, judicial proceedings, and records of the other states. This means, for example, that a properly authenticated copy of a will or deed duly executed in one state will be taken notice of and rights depending on it will be enforced in other states as though the instrument were made therein. Likewise, a marriage legally celebrated in one state will usually be treated as valid in another state, and the facts of a case at law will be recognized in other states without the necessity of retrial. The provision as to full faith and credit does _not_ mean that one state must enforce within its borders the laws of other states, or that its courts in reaching their decisions are bound by the decisions of the courts of its sister states. As a matter of practice, however, courts in one state in deciding difficult questions of law will examine the decisions of the courts of other states on similar points for their own enlightenment, and will show respect for these decisions, the degree of deference depending on the standing of the judges rendering the decision and upon the similarity of the laws and policies of the states concerned. _Surrender of Fugitives from Justice._--In the next place, it is made the constitutional duty of the executive of each state to surrender criminals escaping from other states, in order that they may be returned for trial and punishment in the state from which they have fled. The demand for the surrender of such fugitives is made by the governor of the state from which the criminal has fled, and the governor upon whom the demand is made ought to comply with it unless for very substantial reasons. There is no way, however, by which this obligation may be enforced, and there have been many cases where governors have refused to deliver up criminals escaping from other states--usually for the reason that, in the governor's opinion, the fugitive would not receive a fair trial in the state from which he had fled.
