Horace Gray, Lamar v. Micou (114 U.S. 218)…
“ And there being no evidence that any of Lamar's investments had diminished in value before that time, it is immaterial whether the previous domicile of the wards was in Florida or in Georgia, inasmuch as the propriety of his investments was thereafter to be governed by the law of Georgia.The law of any state of the Union, whether depending upon statutes or upon judicial opinions, is a matter of which the courts of the United States are bound to take judicial notice, without plea or proof. ”
