In criminal cases, is probably the most effective cross-examination technique.

Impeachment

Explanation:

Cross examination refers to the effort that legal workers make in order to get information from the witness in order to make their side look more favorable during the trial.

Impeachment refers to the act of discrediting the witness to prevent him/her from making testimonies on the court.  Impeachment is considered to be the most effective cross examination technique because a team could simply eliminate the witness that will damage their case rather than preparing a defense.
