Depositions are one of the most important tools lawyers use when preparing for trial.
During a deposition, a witness answers questions under oath before trial while a court reporter records the testimony. In many cases today, the deposition is also recorded on video.
These recordings can become extremely powerful evidence when the case reaches a courtroom.
Why Depositions Matter
Depositions allow lawyers to learn what witnesses will say before trial. They also create a permanent record of that testimony.
If a witness later changes their story at trial, the earlier deposition may be used to challenge that testimony. This process is known as impeachment.
What Impeachment Means
Impeachment simply means showing that a witness previously made statements that conflict with what they are saying now. For example, a witness might testify at trial that they never saw a dangerous condition before an accident occurred.
But if that same witness previously stated during a deposition that they had noticed the condition several times, the earlier testimony becomes important.
A lawyer may then confront the witness with the prior statement.
Why Video Can Be So Powerful
Video depositions add another dimension to this process.
Instead of merely reading words from a transcript, the jury can actually see and hear the witness’s earlier testimony.
That allows jurors to evaluate:
- tone of voice
- facial expressions
- hesitation or confidence
- The clarity of the prior statement
When a witness’s trial testimony conflicts with what they said under oath during a deposition, playing the video can make that inconsistency especially clear.
The Legal Framework
Court rules generally allow depositions to be used at trial to contradict or impeach a witness’s testimony.
Because depositions are taken under oath and recorded as part of the litigation process, they can provide a reliable record of prior statements.
When used properly, video excerpts from depositions can therefore become an effective way to highlight inconsistencies and help juries assess credibility.
In the next article, we will look at another question that sometimes arises during trial: whether video deposition excerpts can be played during closing arguments.
