delivered the opinion of the court.
This is a suit in Illinois upon a judgment recovered in Tennessee against the insurance companies, plaintiffs in error. They pleaded and set up at the trial that there never was a valid service upon them in Tennessee and
The ground upon which the present judgment was sustained by the Appellate Court was that as the issue of jurisdiction over the parties was raised and adjudicated after full hearing in the former case it could not be reopened in this suit. The matter was thought to stand differently from a tacit assumption or mere declaration in the record that the court had jurisdiction.
A court that renders judgment against a defendant thereby tacitly asserts, if it does not do so expressly, that it has jurisdiction oyer that defendant. But it must be taken to be established that .a court cannot conclude all persons interested by its mere assertion of its own power,
