by United States Court of Appeals for the Ninth Circuit, United States v. Fuchs (2000)
“ Defendants may have good reasons — tactical reasons — for not raising a particular defense, or for not wanting a jury instruction on that defense. It is not clear or obvious that a jury instruction on the statute-of-limitations defense is required, or even appropriate, in every criminal case. Therefore, it makes sense that a defendant should alert a district court that such an instruction is called for. ”
