obrogo

ob-rŏgo, āvi, ātum, 1, v. a.

I.

Partly to repeal an existing law by proposing a new one, to evade, weaken, invalidate, abrogate it: obrogare est legis prioris infirmandae causā legem aliam ferre, Paul. ex Fest. p. 187 Müll.: obrogatur, id est mutatur aliquid ex primā lege, Ulp. tit. 1, 3;

v. abrogo: huic legi nec obrogari fas est, neque derogari ex hac aliquid licet, neque tota abrogari potest,

Cic. Rep. 3, 22, 33 Mos.:

quid, quod obrogatur legibus Caesaris, quae jubent? etc.,

id. Phil. 1, 9, 16:

quia ubi duae contrariae leges sunt, semper antiquae obrogat nova,

Liv. 9, 34, 9; Suet. Claud 23: cf. id Caes. 28.—
