NON BIS IN IDEM, civil law. This phrase signifies that no one shall be twice tried for the same offence; that is, that when a party accused has been once tried by a tribunal in the last resort, and either convicted or acquitted, he shall not again be tried.

NON CEPIT MODO ET FORMA, pleading. The general issue in replevin. Its form is, "And the said C D, by E F, his attorney, comes and defends the wrong and injury, when, &c., and says, that he did not take the said cattle, (or ' goods and chattels,' according. to the subject of the action,) in the said declaration mentioned or any of them, in manner and form as the said A B hath above complained. And of this the said C D puts himself upon the country."

2. This issue applies to a case where the defendant has not, in fact, taken the cattle or goods, or where he did not take them, or have them in the place mentioned in the declaration. The declaration alleges that the defendant " took certain cattle or goods of the plaintiff, in a certain place called," &c.; and the general issue states, that he did not take the said cattle or goods, -- in manner and form as alleged;" which involves a denial of the taking and of the place in which the taking was alleged to have been, the place being a material point in this action.
