Full Text of Ill. S. Ct. R. 211
Plain-English Summary
Some deposition defects have to be caught immediately or they're waived. Objections to the notice must be served promptly. Objections to a disqualified officer must come before the deposition starts, or as soon as the disqualification is discovered. Objections to question form, oath irregularities, or misconduct during the exam must be raised on the spot, while there's still a chance to fix them.
Other objections survive without immediate action — grounds going to a witness's competency or the admissibility of testimony can wait until the testimony is offered at trial, unless the problem could have been fixed had someone spoken up during the deposition.
A party doesn't need to file a formal motion to suppress just to preserve an objection made at the right time — though anyone can ask the court to rule on objections before trial. Problems with how the deposition was transcribed, signed, or filed have to be raised through a motion to suppress, made promptly once the defect is or should have been discovered.
