Final answer:
A video deposition shown in court becomes part of the official record, treated like live testimony, and does not always require expert authentication.
Step-by-step explanation:
When a video deposition is shown in court, it becomes part of the official record. This means that the video deposition is treated as if the witness were giving live testimony in court. The deposition, once admitted as evidence, is not ignored, excluded as hearsay, or necessarily requires expert authentication unless specific authenticity issues are raised.
It is important to consider factors such as whether the person supplying the testimony is an expert, if there's a consensus among experts, whether the testimony aligns with the expert consensus, and if there's any reason to believe the person may be biased.
