In a suit alleging that a city demolished plaintiff's house without due process of law or just compensation, denial of a motion to lift a stay on federal proceedings is affirmed where: 1) the state proceedings that had taken place did not indicate the type of hostility that would justify lifting the stay; 2) restarting the federal proceedings ran the risk of substantial duplication and/or interference; and 3) there was nothing to prevent the state court from considering plaintiff's new evidence during state court proceedings.
