(a)
given in proceedings in which the United Kingdom was not entitled to immunity by virtue of provisions corresponding to those of sections 2 to 11 above; and

which is final, that is to say, which is not or is no longer subject to appeal or, if given in default of appearance, liable to be set aside.

Subject to section 19 below, a judgment to which this section applies shall be recognised in any court in the United Kingdom as conclusive between the parties thereto in all proceedings founded on the same cause of action and may be relied on by way of defence or counter-claim in such proceedings.
(3)
Subsection (2) above (but not section 19 below) shall have effect also in relation to any settlement entered into by the United Kingdom before a court in another State party to the Convention which under the law of that State is treated as equivalent to a judgment.
