INCOMPATIBILITY

offices, rights. This term is used to show that two or more things ought not to exist at the same time in the same person; for example, a man cannot at the same time be landlord and tenant of the same land; heir and devise of the same thing; trustee and cestui que trust of the same property. 2. There are offices which are incompatible with each other by constitutional provision; the vice-president of though United States cannot act as such when filling the office of president; Const. art. 1, s. 3, n. 5; and by the same instrument, art . 1, s. 6, n. 2, it is directed that no senator or representative shall, during the time for which he was elected, be appointed to any civil office under the authority of the United States, which shall have been created or the emoluments whereof shall have been increased, during such time; and no person holding any office under the United States, shall be a member of either house, during his continuance in office. 3. Provisions rendering offices incompatible are to be found in most of the, constitutions of the states, and in some of their laws. In Pennsylvania, the acts of the 12th of February, 1802, 3 Smith’s Laws of Pa. 485; and 6th of March, 1812, 5 Sm. L. Pa. 309, contain various provisions, making certain offices incompatible, with each other. At common law, offices subordinate and interfering with each other have been considered incompatible; for example, a man cannot be at once a judge and prothonotary or clerk of the same court.
