Opening Statement Is Not Evidence
An opening statement may explain the facts, law, and requested ruling, but unsworn factual assertions in it are not evidence unless established through testimony or other admitted evidence.
Opening statements generally are not made under oath, and facts alleged in opening statements cannot be considered by the Judge unless they are established by other evidence such as sworn testimony.Guidance for Petitioners - Things That Occur During Trial ↗
Witness Examination Sequence
Present witnesses through sworn testimony and direct examination; the opposing side may cross-examine, and the judge may ask questions or request clarification.
After direct examination of each witness by the IRS, you can ask the witness questions (cross-examination). Throughout the trial, the Judge may ask questions and request clarification of evidence from both sides.Guidance for Petitioners - Things That Occur During Trial ↗
Record Closure
After testimony ends and documents are admitted, the record closes and no further evidence may be submitted; bring all documents not already included in a stipulation.
After all the witnesses have testified and all the documents have been entered into evidence, the trial will be over and the record will be closed. This means that no more evidence may be submitted to the Court.Guidance for Petitioners - Things That Occur During Trial ↗
