In South African law, a clear distinction is drawn between interlocutory and final interdicts/injunctions. The following requirements are generally accepted to apply in order to obtain an interlocutory or interim interdict:
(a) a right that is prima facie established although open to some doubt;
(b) a well-grounded apprehension of irreparable harm if the interlocutory relief is not granted and the ultimate relief is eventually granted;
(c) the balance of convenience must favour the granting of interlocutory relief; and
(d) the absence of any other satisfactory remedy.
In intellectual property cases, the irreparable harm will generally be economic. The apprehension of irreparable harm must be objectively reasonable.
