La. Code Evid. art. 613
Current with changes from the 2024 First and Second Extraordinary Sessions
Except as the interests of justice otherwise require, extrinsic evidence of bias, interest, or corruption, prior inconsistent statements, conviction of crime, or defects of capacity is admissible after the proponent has first fairly directed the witness' attention to the statement, act, or matter alleged, and the witness has been given the opportunity to admit the fact and has failed distinctly to do so.
