Europe and America for many years, and many of the decisions are apparently conflicting. Divorces are of two kinds, ammsa et thoro, and a vinculo; and the causes of divorce are as different and various as there are different states and governments. By the civil law, either party might renounce the marriage union at pleasure. Justinian for a short time abolished divorces, but was compelled to revive them again. He restored the unlimited freedom of divorce, and gave as a reason that the hatred, misery, and crimes, which often flowed from indissoluble connections, required that marriages should be subject to dissolution by mutual will and consent. By the ecclesiastical law, a marriage may be dissolved and declared void ah initio, for canonical impediments existing previous to marriage. In the Roman Catholic states, heretofore, divorces were not allowed, because marriage was considered by them a sacrament and indissoluble. The Napoleon Code admits of divorces for several named causes to be pronounced by the tribunals, where the parties cannot agree on a dissolution, and in all cases where the parties agree thereto. In England, a divorce a vinculo is seldom granted except for adultery, but divorces a mensa et thoro are very common and often for very trifling causes. In some of our states, divorces a vinculo are restrained by constitutional provisions, which require the assent of two-thirds of the legislature founded on previous judicial investigation. In some, divorces are granted solely by special acts of tlm legislature; in others, divorces a vinculo, are judicially granted for adultery only; and in others, not only for adultery but also for ill treatment, abuse, abandonment, and many other causes. In our state, divorces a vinculo only are granted; a divorce a mensa et thoro is not authorised. The causes of divorce are, 1, a former subsisting marriage; 2, impotency; 3, adultery; 4, abandonment; 5, condemnation for a felony; 6, barbarous and inhuman treatment; and 7 and lastly, ££in any other case where the Court in their discretion, shall consider it reasonable and proper that a divorce should be granted.”
The first point is, how far the legislature of a state can interfere with a marriage contract under the constitution of the United States, which prohibits the states from passing laws impairing the obligation of contracts.
