When taking or defending a deposition, always keep in mind that you’re making a record for the jury. Sometime later, perhaps years after the deposition took place, a jury may hear parts of the deposition and you want everything to be there and be clear.
A witness’s deposition can be used for impeachment (i.e., to attack the witness’s credibility) by showing that the testimony on the stand isn’t consistent with the deposition testimony or “for any other purpose permitted by the Evidence Code.” CCP §2025.620(a). The quoted language permits the deposition to be used to show both prior inconsistent statements (Evid C §1235) and prior consistent statements (Evid C §1236). Next time you have depo testimony that will impeach a witness, follow these 10 steps.
