Rule 607 Who May Impeach a Witness

If someone testifies in court, any lawyer in the case can try to show that the witness should not be believed. This includes the lawyer who brought that witness to the stand in the first place.

In the past, 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.
