9. In COVEY v. TOWN OF SOMERS, 351 U.S. 141, 146–47, 76 S.Ct. 724, 727, 100 L.Ed.

1021, 1026 (1956), the Court held that notice by mail of a foreclosure proceeding for delinquent property taxes on real property, although ordinarily sufficient, would not satisfy due process when it was mailed to someone known to have been adjudged insane and committed to a hospital, and who was without the protection of a guardian. Would notice by mail have been sufficient if the town authorities were unaware of the defendant’s disability?
