"[W]hen legislation that is enacted to repeal, amend or otherwise modify an existing statute, is declared unconstitutional, it is a nullity and . . . the extant statute remains operative without regard to the unsuccessful and invalid legislation." State v. Clark, 367 N.W.2d 168, 169 (N.D. 1985).
The Legislature is presumed to know the law when enacting legislation. See State v. Clark, 367 N.W.2d 168, 170 (N.D. 1985). When the historical circumstances for additional time after service by mail are considered with the statutes superseded by N.D.R.Civ.P. 6 and the Legislature's reenactment of the mechanic's lien law after the adoption of the rules of civil procedure, we conclude the Legislature intended the provisions for additional time after service by mail under N.D.R.Civ.P. 6(e) to apply when an owner chooses to serve a written demand by registered mail under N.D.C.C. § 35-27-25.
