(1) Subject to the provisions of this section, a judgement to which Part 1 applies or would have applied if a sum of money had been payable, whether it can be registered or not, and whether, if it can be registered it is registered or not, shall be recognised in any court in Saint Lucia as conclusive between the parties in all proceedings founded on the same cause of action and may be relied on by way of defence or counterclaim in any such proceedings.
(2) This section shall not apply in the case of any judgement—
(a) where the judgement has been registered and the registration thereof has been set aside on some ground other than—
(i) that a sum of money was not payable under the judgement,
(ii) that the judgement had been wholly or partly satisfied, or
(iii) that at the date of the application the judgement could not be enforced by execution in the country of the original court; or
(b) where the judgement has not been registered, it is shown (whether it could have been registered or not) that if it had been registered the registration thereof would have been set aside on an application for that purpose on some ground other than one of the grounds specified in subsection 2(a).
(3) This section shall not be taken to prevent any Court in Saint Lucia recognising any judgement as conclusive of any matter of law or fact decided therein if that judgement would have been so recognised before the passing of this Act.
