Separate direct knowledge from assumptions when giving evidence

Before attending, review when and where events occurred and what you personally observed. Do not present someone else’s account, an interpretation or an uncertain memory as direct observation; clearly identify what you do not know or cannot reliably recall.

Listen to the complete question and request clarification or an interpreter where needed. Any statement or record presented for confirmation should reflect what you actually said. Report a material recording error through the official procedure rather than leaving a known inaccuracy unaddressed.

Take threats, pressure or promised benefits intended to change your testimony seriously and preserve evidence of them. A later correction does not always provide immunity; statutory conditions and the stage of proceedings matter, so no automatic exemption should be assumed.
