ANNOTATION
Reapportionment leaving district without resident senator until 1985 unconstitutional. Drawing boundaries of two senatorial districts so that one district encompasses the residences of two incumbent state senators while no state senator resides in the other, and setting the senatorial election for the first district for 1982 and for the other district for 1984, with the result that no senator will reside in the latter district until 1985, is a violation of constitutional guarantees of legislative representation. In re Reapportionment of Colo. Gen. Ass'y, 647 P.2d 191 (Colo. 1982).
Applied in Kallenberger v. Buchanan, 649 P.2d 314 (Colo. 1982).
