Heading: trial court's refusal to admit expert testimony

Text: 18 During the trial, at the beginning of the second day, and without having given the prosecution notice as required by Rule 12.2 of the Federal Rules of Criminal Procedure, Rivera informed the court and the prosecution that he would offer an expert witness to testify concerning his alleged mental deficiencies, including the inability to read. The court rejected the proffered testimony, and its doing so was not manifestly erroneous. United States v. Demma, 523 F.2d 981, 987 (9th Cir.1975) (en banc). See also United States v. Byers, 730 F.2d 568, 570-71 (9th Cir.1984).
