ERROR to the Court of Appeals of the State of Maryland.

Mrs. Elizabeth Patterson, a resident of Baltimore, Md., returned, in accordance with the law of that State, to the proper board of assessors, the following property: City of New York stock, six per cent; City of New York stock, seven per cent; County of New York stock, seven per cent; County of New York stock, i x per cent; State of New York stock, six per cent; State of Pennsylvania stock, six per cent; State of Ohio stock, six per cent; and City of Philadelphia stock, six per cent. She stated their several amounts, and claimed their exemption from taxation because they were of a public character, and, except a portion of the City of Philadelphia stock, were exempt from taxation by the laws of the States respectively authorizing their issue, while that portion had always been subjected by Pennsylvania to a tax which she had paid to that State. They were of the character known as 'registered;' i.e., transferable only on the public record books of the States and municipalities issuing them, and the interest was paid only at places provided by the laws of those States, and beyond the boundaries of Maryland. The board of control and review by which this return was revised, disallowed her claim for exemption. She thereupon filed a petition in the Baltimore City Court, praying that the above—described property should be stricken from the lists. The order of the court granting the relief prayed was reversed by the Court of Appeals, whereupon she sued out this writ of error. She died during its pendency, and her executor was substituted in her stead.

Mr. I. Nevitt Steele and Mr. Charles J. Bonaparte, for the plaintiff in error, submitted her following propositions:——

The asserted right of one State to tax the loans of its citizens to another State involves its right to prohibit such loans, and forbid all dealings on the part of its citizens with the governments of other States. Such a right assumes the existence of a power which is inconsistent with the mutual amity imposed on all the States by the Constitution.

The registered public debt of a State is properly subject to its sovereignty, and therefore to its taxing power; and whenever this sovereignty is exercised by the public acts of the State, either taxing or exempting from taxation this debt, they must, under art. 4, sect. 1, of the Constitution, be recognized by the courts of other States as giving it for taxation a situs in the State by which it was incurred.

The same property cannot at the same time have more than one situs for the purpose of taxation. It, therefore, follows, and it is the only Federal question presented by this record, that the proper situs for taxation of property of this description is, under the Constitution, in the State owing the debt. This view finds support also in the following considerations:——

1. It shuts the door to fraud and perjury. The ownership of the debt of each State can be determined by an inspection of public records, always open to its fiscal officers; that of the debt of other States can be learned only from the returns of taxpayers. To say nothing of the gain to public morality, the advantages to the treasury, in the narrowest sense, of a mode of collection dependent in no wise upon the consciences of contributors, would largely exceed the amount raised by taxing foreign investments.

2. It simplifies the whole method of collection. The stock, the thing taxed, remains within the State, subject to levy and sale whenever the tax thereon is in arrear. If a resident of one State, on the other view, invested all his property in the debts of other States (a perfectly supposable contingency), it is hard to see how the State where he resides could compel him to pay taxes.

3. It gives the public debt of each State a fixed value for all investors, and in each of the great financial centres of the country. This is of almost incalculable advantage to the States that borrow, and to the capitalists who wish the largest choice of investments. The opposite construction would, in the last resort, confine the loans of each State to its own citizens.

4. Finally, it gives the citizens of one State a direct interest in the good order and prosperity of sister States; tends to prevent sectional jealousies and antagonisms; avoids the danger of reciprocally hostile legislation by the several States against the crd it of their neighbors, and promotes the 'more perfect union' aimed at by the Constitution.

Mr. Charles J. M. Gwin, Attorney—General of Maryland, contra.
