Until recently the fact that one state had jurisdiction to tax intangibles was no basis for asserting that another state did not, there being apparently no constitutional impediment to double taxation. Nor did the fact that a state lacked jurisdiction to tax property in intangibles necessarily imply an absence of power to tax succession to that property. Both doctrines have been repudiated by the United States Supreme Court in Farmer's Loan & Trust Co. v. Minnesota and Baldwin v. Missouri, decided during the last term.
