SECTION 30

Compulsory execution and protective measures shall not apply to persons who enjoy immunity from execution. However, any debt which is certain, due and owed by state corporations or firms, regardless of their legal form and mission, shall give rise to a set-off against debts which are also certain, due and owed them, subject to an agreement of reciprocity. The debts of the state corporations and firms referred to in the preceding paragraph may only be considered certain, within the meaning of this article , where they arise from either an acknowledgement by the said corporations and firms of the debts or from a writ which is enforceable within the territory of the State where the corporations and firms are located.
