I did a
little research on the opinions of the US Federal Court of Appeals, 9th Circuit (includes Washington State and other west-coast States). By little, I mean I examined the two most recent criminal-case opinions available on the 9th Circuit's web site:
http://www.ca9.uscourts.gov/opinions/
1. The first case required only a judgment on a point of law; that was all that the appellant was seeking. It was 10 pages long, and IMO, perfectly clear. No fancy language. The opinion stated that a US Federal law making misstatements to a bank an offense did not require that the bank suffer a financial loss, based on a literal reading of the statute.
2. The second case required a review of the interpretation of evidence by a jury; this interpretation important to a sentencing decision in a case involving a conspiracy to distribute heroin. There was also a question about whether some of the prosecution questioning of a defense witness had been admissible or not. It was 27 pages long, and IMO, perfectly clear. No fancy language or Latin jargon, no literary flights, all perfectly straight-forward.
Of interest, the Court of Appeals reversed the sentencing decision and sent the case back for re-sentencing, because that depended on the amount of heroin sold, and the Court of Appeals found that the jury of the District Court had based its sentencing decision on a speculation that the amount sold would eventually exceed a 1 kilogram limit, rather than on a reasonable estimate of the actual amount sold during the period the conspiracy was operating. The Court of Appeals
reviewed the evidence testimony and performed its own calculations in making this judgment.
The question of the witness testimony was decided in favor of the government because the defense witness had volunteered some information - that her brother was not involved with drugs - which very likely she knew to be false, since he had been previously imprisoned on a drug charge and had escaped, and thus her testimony could be impeached. And the Court of Appeals hypothesized if this question was an abuse of discretion by the District Court, there was other incontrovertible evidence including cell phone records and co-conspirator testimony to convict the brother, so that the error by the District Court was harmless.
