NON EST INVENTUS, practice. The sheriff's return to a writ1 requiring him to ,arrest the person of the defendant2, which signifies that he is not to be found within his jurisdiction3. The return is usually abbreviated4 N. E. I. Chit. Pr. Index, L. t.
NON FEASANCE, torts, contracts. The non-performance of some act which ought to be performed.
2. When a legislative5 act requires a person to do a thing, its non feasance will subject the party to punishment; as, if a statute6 require the supervisors7 of the highways to repair such highways, tlie neglect to repair them may be punished. Vide 1 Russ. on Cr. 48.
3. Mere8 non-feasance does not imply malice9; this is strongly exemplified in the case of a plaintiff, who, having issued a writ of capias against his debtor10, afterwards received the debt, and neglected to countermand11 tlie writ, in consequence of which the defendant was afterwards arrested. On a suit brought by the former defendant against tlie former plaintiff, it was held that the law did not impose on the first plaintiff the duty of countermanding12 his writ. If he had refused to give the countermand when requested, it might have been evidence of malice, but in such case there would have been something beyond mere non-feasance, an actual refusal. 1 B & P. 388; 3 East, R. 314; 2 Bos. & P. 129.
4. There is a difference between nonfeasance and misfeasance, (q. v.) or malfeasance. (q. v.) Vide 2 Kent, Com. 443 Story on Bailm. 9, 165; 2 Vin. Ab. 35 1 Hawk13. P. C. 13; Bouv. Inst. Index, h. t.
