This court in the case of Macaulay v. R. Z. B. Austria (2003) 18 NWLR (Pt.852) 282 at pp. 298H -299 A – B, per Kalgo, JSC observed as follows: “By this provision, irrespective, regardless or inspite of any other provision in the 1990 Act, any judgment of a foreign country including United Kingdom to which part 1 of that Act was not extended, can only be registered within twelve months from the date of the judgment or any longer period allowed by the court registering the judgment since the provisions of Part 1 of the said Act had not been extended to it. Section 4 of the 1990 Act which speaks of registering a judgment within 6 years after the date of judgment only applies to the countries where Part 1 of the said Act was extended, that is to say, when the Minister made an order under the 1990 Act; and in this case it was not.”
REGISTRATION OF FOREIGN JUDGEMENT DOES NOT DEPRIVE THE ORIGINAL COURT OF JURISDICTION
I agree that the registration of a judgment in a foreign Court for purposes of execution does not rob the original court of its jurisdiction over the matter and the execution of its judgment. For, the judgment-creditor could be enforcing the judgment in both jurisdictions wherever he can find the debtor’s property. But the matter in issue herein, which in my view had been decided by the registering court in England which had jurisdiction so to do, and the Arbitrator duly appointed by consent of parties in accordance with the “compromise” order of the registering court, ought not be relitigated in the original court in Nigeria. I should think that doing so tantamount to either asking the Nigerian Court to sit on appeal over the decision of another Court which had already exercised coordinate jurisdiction available to either Court, or setting aside the award of the Arbitrator which the Respondent had not challenged in accordance with the known principles governing arbitral proceedings.
