§ 2032.510.Physical examination; attendance of attorney or attorney's representative;

An examination conducted at the defendant's request does not happen unsupervised. The examinee's attorney, or the attorney of the party producing the examinee, or that attorney's representative, is entitled to attend and observe any physical examination conducted for discovery purposes, and to record stenographically or by audio technology anything said to or by the examinee during any phase of it.

That presence comes with real limits on both sides. The observer may monitor the exam but cannot participate in or disrupt it, and if an attorney's representative rather than the attorney serves as observer, that representative needs written authorization identifying them, signed by the attorney. If, in the observer's judgment, the examiner turns abusive toward the examinee or tries unauthorized diagnostic tests or procedures, the observer may suspend the exam so the examinee's side can move for a protective order. The reverse holds too: if the observer starts participating in or disrupting the exam, the examiner may suspend it so the side conducting the exam can move for its own protective order. Whoever loses either kind of protective-order motion faces a mandatory monetary sanction, absent substantial justification or unjust circumstances.
