Any party, including the party that called the witness, may attack the witness’s credibility.
If a witness takes the stand, any lawyer in the courtroom can try to show that the witness should not be believed. This includes the lawyer who brought that witness to testify in the first place.
In older court practice, lawyers were not allowed to challenge the credibility of their own witnesses. This rule removes that restriction. Now, if your own witness says something harmful or untrue, you can question their reliability just like the other side can.

This rule tracks F.R.E. 607. This rule modifies existing Delaware case law. See Concord Towers, Inc. v. Long, Del. Supr., 348 A.2d 325 (1975). D.R.E. 607 was amended in 2017 in response to the 2011 restyling of the Federal Rules of Evidence. The amendment is intended to be stylistic only. There is no intent to change any result in ruling on evidence admissibility.
