If an attorney determines that a witness's testimony is critical during trial, what is a potential challenge to obtaining that testimony?

The potential challenge reflected in the selected answer relates to the adversarial nature of trial proceedings. During a trial, opposing counsel has the right to challenge the validity, credibility, and relevance of the witness's testimony. This can involve cross-examination, where the opposing party may attempt to discredit the witness or introduce contradictions. These challenges can significantly hinder the effectiveness of the testimony and potentially affect the overall outcome of the case.

While there are other considerations, such as logistical issues or the availability of the witness, the primary concern at the trial stage is how the opposing counsel will respond to the witness's testimony, which can be a direct threat to its acceptance and impact.
