Witness examination classifications distinguish examination-in-chief, cross-examination, and re-examination according to the party conducting each stage in proceedings.

Examination-in-chief is conducted by the party calling a witness, while cross-examination is conducted by the adverse party. Re-examination is conducted by the party who called the witness after cross-examination. These classifications distinguish the parties' respective roles in witness examination and identify re-examination as subsequent to cross-examination in the evidentiary process.
