AUTHORITY, government. The right and power which an officer has in the exercise of a public function to compel obedience to his lawful commands. A judge, for example, has authority to enforce obedience to his not being correct. Merlin, Repertoire, mot Authentique.

AUTOCRACY. The name of a government where the monarch is unlimited by law. Such is the power of the emperor of Russia, who, following the example of his predecessors, calls himself the autocrat of all the Russias.

AUTRE VIE. Another's life. Vide, Pur autre vie.

AUTREFOIS. A French word, signifying formerly, at another time; and is usually applied to signify that something was done formerly, as autrefois acquit, autrefois convict, &c.

AUTREFOIS ACQUIT, crim. law, pleading. A plea made by a defendant, indicted for a crime or misdemeaner, that he has formerly been tried and acquitted of the same offence. See a form of this plea in Arch. Cr. PI. 90.

2. To be a bar, the acquittal must have been by trial, and by the verdict of a jury on a valid indictment. Hawk. B. 2, c. 25, s. 1; 4 Bl. Com. 335. There must be an acquittal of the offence charged in law and in fact. Stark. PI. 355; 2 Swift's Dig. 400 1 Chit. Cr. Law, 452; 2 Russ. on Cr. 41.

3. The Constitution of the U. S., Amend. Art. 5, provides that no person shall be subject for the same offence to be put twice in jeopardy of life or limb. Vide generally, 12 Serg. & Rawle, 389; YeIv. 205 a, note.

AUTREFOIS ATTAINT, crim. law. Formerly attainted.

2. This is a good plea in bar, where a second trial would be quite superfluous. Co. Litt. 390 b, note 2; 4 Bl. Com. 336. Where, therefore, any advantage either to public justice, or private individuals, would arise from a second prosecution, the plea will not prevent it; as where the criminal is indicted for treason after an attainder of felony, in which case the punishment will be more severe and more extensive. 3 Chit. Cr. Law, 464.

AUTREFOIS CONVICT, crim. law, pleading. A plea made by a defendant, indicted for a crime or misdemeanor, that he has formerly been tried and convicted of the same.

2. As a man once tried and acquitted of an offence is not again to be placed in jeopardy for the same cause, so, a fortiori, if he has suffered the penalty due to his offence, his conviction ought to be a bar to a second indictment for the same cause, least he should be punished twice for the same crime. 2 Hale, 251; 4 Co, 394; 2 Leon,. 83.

3. The form of this plea is like that of autrefois acquit; (q. v.) it must set out the former record, and show the identity of the offence and of the person by proper averments. Hawk. B. 2, c. 36; Stark. Cr. Pi. 363; Arcb. Cr, PI, 92; 1 Chit. Cr. Law, 462; 4 Bl. Com. 335; 11 Verm. R. 516.

AVAIL. Profits of land; hence tenant paravail is one in actual possession, who makes avail or profits of the land. Ham. N. P. 393.
