If the prosecution offers evidence in a California criminal trial, an objection should identify the particular evidence and the legal reason it should be excluded, in time for the judge to rule. A motion to exclude or strike can serve the same function. For an appeal claiming that evidence was wrongly admitted, Evidence Code section 353 requires a timely, specific objection or motion on the record. A preserved issue still requires a showing that the ruling was wrong and caused the prejudice required by the statute; an objection alone does not win an appeal.
Make the reason clear while the court can act
Counsel should point to the exhibit, statement, or line of testimony and state the actual exclusion ground—for example, a specified hearsay problem, lack of foundation, or a request for the court to weigh probative value against unfair prejudice under Evidence Code section 352. Saying only “objection” may leave the court and the party offering the evidence unable to address the problem. An objection after the evidence has already been heard may require a timely motion to strike. The transcript should show what was challenged and how the judge ruled. (Evidence Code § 353; People v. Partida)
The California Supreme Court in Partida explains why the ground matters: it lets the other side respond and gives the trial judge a chance to decide the real dispute. On appeal, a defendant may challenge the admission of evidence on the exclusion ground raised at trial. The defendant cannot ordinarily turn that objection into a different reason the trial judge was never asked to consider. Partida allowed a narrow additional argument that the alleged error in overruling the actual objection also had a due-process consequence; it did not excuse a new and distinct ground for excluding the evidence. (People v. Partida)
Does a motion in limine count?
Sometimes. In People v. Morris, the California Supreme Court held that a classic trial motion in limine can preserve an objection without repeating it when it: (1) states the specific legal ground later raised on appeal, (2) targets a particular, identifiable body of evidence, and (3) is heard when the trial judge can decide admissibility in its proper context. A clear denial under those conditions can make a second identical objection pointless.
That is not a blanket rule for every pretrial filing. If a motion is vague, the judge reserves a ruling, the actual testimony differs from what was predicted, or trial events materially change the context, counsel may need to object when the evidence is offered so the court can rule on the real issue. Morris confined its analysis to classic in-limine motions heard by the trial judge at the beginning of or during trial; other pretrial motions can have their own preservation rules. Confirm the precise ruling and whether the court asked for renewed objections. (People v. Morris)
What record should appellate counsel receive?
Keep the filed motion, opposition, hearing and trial transcript pages, exhibits, any limiting instruction, and the judge’s ruling. Mark when the evidence was offered, the words used in the objection, and whether counsel later renewed it or sought to strike the evidence. An appellate lawyer can then compare the trial ground with the proposed appeal ground and assess both error and prejudice under section 353. Obtaining a transcript later helps review the issue; it does not create a trial objection that never occurred.
This is the rule for a claim that admitted evidence should have been excluded. Jury selection, excluded defense evidence, plea challenges, and other trial errors can require different steps.
