Where a judgment has been registered under this Schedule, the registering court may, if it is satisfied that any person against whom it is sought to enforce the judgment is entitled and intends to apply under the law of the part of the United Kingdom in which the judgment was given for any remedy which would result in the setting aside or quashing of the judgment, stay (or, in Scotland, sist) proceedings for the enforcement of the judgment, on such terms as it thinks fit, for such period as appears to the court to be reasonably sufficient to enable the application to be disposed of.
