This is known as the "rule of completeness" or "rule of examination-in-chief," and it is a fundamental principle of cross-examination. The cross-examiner cannot ask questions about topics that were not covered during direct examination, except in limited circumstances such as attacking the witness's credibility or impeaching their testimony. However, questions about witness capacity, such as their ability to perceive, remember, or communicate information, may be asked on cross-examination even if they were not covered during direct examination.
