In relation to a State which has two or more systems of law or sets of rules applicable to different categories of persons in respect of succession, any reference to the law of that State shall be construed as referring to the system of law or set of rules determined by the rules in force in that State. In the absence of such rules, the system of law or the set of rules with which the deceased had the closest connection shall apply.
