Warden, 96 Nev. 886, 620 P.2d 859 (1980), the order of the district court is reversed and the case is remanded for a determination of whether sufficient grounds exist which excuse appellant’s failure to raise the issues contained in his petition on a direct appeal from his conviction, and if so, for resolution of the merits of the petition.
