My humble view is that the word “interlocutory” simply means “(of an order, judgment, appeal, etc) interim or temporary; not constituting a final resolution of the whole controversy.” A “ruling” is “the outcome of a Court’s decision either on some points of law or on the case as a whole.” See Blacks Law Dictionary, 9th edition, pages 889 and 1450.
