The offences for which a guilty officer may be impeached are treason, bribery, and other high crimes and misdemeanors; art. 2, s. 4. The constitution defines the crime of treason; art. 8, s. 8. Recourse must be had to the common law for a defi- nition of bribery. Not having particularly mentioned what is to be understood by "other high crimes and misdemeanors, resort, it is presumed, must be had to par- liamentary practice and the common law in order to ascertain what they are; Story, Const. § 795. It it said that impeachment may be brought to bear on any offense against the constitution or the laws which is deserving of punishment in this manner or is of such a character as to render the officer unfit to hold his office. It is prim- arily directed against official misconduct, and is not restricted to political crimes alone. The decision rests really with the senate; Black, Const. L. 121, The guilt of the accused must be established beyond a reasonable doubt; 37 Neb. 96. The mode of proceeding in the institution and trial of impeachments is as follows: When a person who may be legally im- peached has been guilty, or is supposed to have been guilty, of some malversation in office, a resolution is generally brought forward by a member of the house of rep- resentatives, either to accuse the party, or for a committee of inquiry. If the com- mittee report adversely to the party ac- cused, they give a statement of the charges and recommend that he be impeached. When the resolution is adopted by the house, a committee is appointed to impeach the party at the bar of the senate, and to tate that the articles of impeachment against him will be exhibited in due time and made good before the senate, and to demand that the senate take order for the appearance of the party to answer to the impeachment. The house then agree upon the articles of impeachment, and they are presented to the senate by a committee appointed by the house to prosecute the impeachment. The senate then issues pro- cess, summoning the party to appear at a given day before them, to answer to the articles. The process is served by the sergeant-at-arms of the senate, and a re- turn is made of it to the senate under oath. On the return-day of the process, the senate resolves itself into a court of impeachment, and the senators are sworn to do justice according to the constitution and laws. The person impeached is called to answer, and either appears or does not appear. If he does not appear, his default is recorded, and the senate may proceed ex parte. If he does appear, either by himself or attor- ney, the parties are required to form an issue, and a time is then assigned for the trial. The final decision is given by yeas and nays; but no person can be convicted without the concurrence of two-thirds of the members present; Const. art. 1, s. 2, cl. 6.

The judgment, in cases of impeachment, does not extend further than to removal from office and disquali- fication to hold and enjoy any office of honor, trust, or profit under the United States. Disqualification, as a punishment, is discretionary with the senate; Black, Const. L. 122. The party impeached re- mains liable to trial and punishment ac- cording to law. See UNITED STATES COURTS. Proceedings on impeachments under the state constitutions are somewhat similar. In England, the articles of impeachment are a kind of indictment found by the house of commons, and tried by the house of lords. It has always been settled that a peer could be impeached for any crime. It was formerly believed that a commoner could only be impeached for high misde- meanors, not for capital offences; 4 Bla. Com. 260; but it seems now settled they may be impeached for high treason; May's Parl. Prac. Ch. 23. Impeachments have been very rare in England in modern times. In Evidence. An allegation, support- ed by proof, that a witness who has been examined is unworthy of credit. Every witness is liable to be impeached as to his character for truth; and, if his general character is good, he is presumed at all times to be ready to support it; 49 Ill. 299. See 97 Ala. 14. It is not admissible to impeach a defend- ant's testimony by showing that at a former trial for a like offence, he raised a similar issue and was contradicted; 155 Mass. 168. An accused person who testifies in his own behalf, is subject to impeachment, as other witnesses, by evidence of previous contra- dictory statements; 98 Ala. 169; 86 Tenn. 259. A witness cannot be impeached by the contradict
