“ In any case, exercise by the state courts of their jurisdiction to adjudicate the parties' rights to land located in those states involves no interference with or impairment of the jurisdiction of the federal court in Illinois, and affords no ground for the injunction restraining prosecutions of the suits in the state courts. ”

“ Maintenance of the suit in the district court does not require possession of the property by that court or require it to assume supervisory or administrative control of it even though exercise of its control over the trustees, at least until it has determined that respondent has some interest in the property, nor has the court undertaken to exercise such control. ”

“ On motion of respondent the district court granted a temporary injunction restraining the prosecution of the pending suits in Minnesota and Wisconsin. It also enjoined further prosecution of a probate proceeding brought by petitioner Richard Centerbury Mandeville in the County Court of Rock County, Wisconsin, which sought a construction of the will and a determination of the rights of the parties under it, but with the proviso that the injunction should not restrain the probate of the will or a determination of inheritance taxes due to the state. ”
