What phrase is used to indicate that a witness has previously taken an oath?

The phrase "previously sworn" is used to indicate that a witness has taken an oath at an earlier time, affirming that their testimony is given under the legal requirement of telling the truth. This terminology is important in legal contexts because it establishes that the witness has already committed to providing truthful information, which underscores the reliability of their statements during the current proceedings.

Using "previously sworn" clarifies that the witness's commitment to honesty is not newly established but rather has been confirmed in the past. This can be important for the credibility and weight of the testimony being presented. Furthermore, this phrase is commonly recognized in legal environments, reinforcing its appropriateness for use in court or official documentation.

In contrast, "currently sworn" suggests an ongoing oath, "under oath now" implies immediacy and the necessity to adhere to the oath at that moment, and "solemn promise" lacks the formal legal connotation that defines the specific act of taking an oath in a legal context. Therefore, "previously sworn" is the most precise terminology for this circumstance.
