A radical change was made in 1847. All the foregoing causes were at once superseded by a sweeping provision which is without parallel in the previous history of New England. By an act of that year, amended in one particular in 1849, any justice of the supreme judicial court, at any term held in the county of the parties, may grant decrees of divorce from the bond of wedlock, when "in the exercise of a sound discretion" he may "deem the same reasonable and proper, conducive to domestic harmony, and consistent with the peace and morality of society."[66] Moreover, to understand the full import of this law we must take into account an enactment of 1850. In no case is the libellant then to be "restricted to the proof of causes happening within the state," or where either of the persons is "residing within the state," but he "may allege and prove any facts tending to show that the divorce would be" just according to the provision of the law in question.[67] The act of 1847 remained in force until 1883,[68] when a new statute appeared which completely transformed the divorce system of Maine. Seven causes of dissolution _a vinculo_ are prescribed. These are (1) adultery; (2) impotence; (3) extreme cruelty; (4) utter desertion for three years; (5) gross and confirmed habits of intoxication; (6) cruel and abusive treatment; and (7) gross, cruel, and wanton neglect or refusal of the husband, being able, to provide for the wife.[69] At the same time the decree from bed and board is abolished; and the decree _nisi_ is instituted in practically the same form as in Massachusetts.[70] In 1897 a modified provision as to residence was adopted, and two years later the law took its present form. The same seven causes sanctioned by the act of 1883 are retained, except that under the fifth head the qualifying words are added, "from the use of intoxicating liquors, opium, or other drugs."[71] [66] The act of July 13, 1847, gave a "majority" of the justices this power: _Acts and Resolves_ (1847), 8; but this was amended in harmony with the text in 1849: _Acts and Resolves_ (1849), 104. [67] _Ibid._ (1850), 150, 151. [68] Except by an act of 1863, in addition to the "blanket" provision of 1847, three years' wilful desertion is specified as a cause: _Laws_ (1863), chap. 211, sec. 2; also in _Rev. Stat._ (1871), 488. [69] _Acts and Resolves_ (1883), chap. 212, secs. 1, 2, p. 175 (March 13); _Rev. Stat._ (1884), 520-23. [70] _Acts and Resolves_ (1883), chap. 212, sec. 4, pp. 175, 176; _Rev. Stat._ (1884), 522. [71] Compare the act of March 2, 1897: _Acts and Resolves_ (1897), 232, 233, with that of March 15, 1899: _ibid._ (1899), 89.
