(1991). "Incorrect state court evidentiary rulings cannot serve as a basis for habeas relief unless federal constitutional rights are affected." Whelchel v. Washington, 232 F.3d 1197, 1211 (9th Cir. 2000) (internal citation and quotations omitted). With respect to an incorrect evidentiary ruling, in order to establish a constitutional violation, a petition on habeas review must show that the evidentiary ruling was so prejudicial that it rendered the trial "fundamentally unfair." Ortiz-Sandoval, 81 F.3d at 897.
