2.10 Explanatory: Impeachment of Witness, Prior Conviction is a legal process whereby a party in a court of law attempts to discredit a witness's testimony in order to weaken the opposing party's case. This is done by introducing evidence of a prior conviction or other misconduct of the witness. The two main types of impeachment are direct and indirect. Direct impeachment involves introducing evidence of the witness’s prior convictions or other misconduct, while indirect impeachment involves arguing that the witness’s testimony is unreliable or unbelievable. The aim of impeachment is to raise doubts about the veracity of the witness's testimony, and to ultimately weaken the opposing party's case.
