Is the contact between the defendant's lawyer and the witness collusion?

The contact between the defendant's lawyer and the witness is not collusion. Lawyers collude with alleged defenders and agents ad litem to destroy evidence, forge evidence and obstruct testimony. An agent ad litem or a defender who destroys evidence irresponsibly, negligently or negligently does not constitute the crime of a defender or an agent ad litem destroying evidence, forging evidence or obstructing testimony. Article 306 of the Criminal Law stipulates that in criminal proceedings, defenders and agents ad litem who destroy or falsify evidence, help the parties to destroy or falsify evidence, threaten or induce witnesses to change their testimony about facts or commit perjury shall be sentenced to fixed-term imprisonment of not more than three years or criminal detention. If the circumstances are serious, they shall be sentenced to fixed-term imprisonment of not less than three years but not more than seven years. Witness testimony or other evidence provided, presented or quoted by defenders or agents ad litem is inaccurate, not intentionally forged, and does not belong to forged evidence.
