Michigan Trust Company v. Ferry…
“ Ordinarily jurisdiction over a person is based on the power of the sovereign asserting it to seize that person and imprison him to await the sovereign's pleasure. But when that power exists and is asserted by service at the beginning of a cause, or if the party submits to the jurisdiction in whatever form may be required, we dispense with the necessity of maintaining the physical power, and attribute the same force to the judgment or decree whether the party remain within the jurisdiction or not. ”
