Where, immediately before the appointed day, an existing State is subject to any liability in respect of an actionable wrong other than breach of contract, that liability shall—
(a) if there be only one successor State, be a liability of that State;
(b) if there be two or more successor States and the cause of action arose wholly within the territories which as from that day are the territories of one of them, be a liability of that successor State; and
(c) in any other case, be initially a liability of the principal successor State, but subject to such financial adjustment as may be agreed upon between all the successor States concerned, or in default of such agreement, as the Central Government may by order direct.
