(b) As to Disqualification of Officer or Person. Objection to taking a deposition because of
disqualification of the officer or person before whom it is to be taken is waived unless made before the taking of the deposition begins or as soon thereafter as the disqualification becomes known or could have been discovered with reasonable diligence.
(c) As to Competency of Deponent; Admissibility of Testimony; Questions and Answers; Misconduct; Irregularities.
(1) Grounds of objection to the competency of the deponent or admissibility of testimony which might have been corrected if presented during the taking of the deposition are waived by failure to make them at that time; otherwise objections to the competency of the deponent or admissibility of testimony may be made when the testimony is offered in evidence.
(2) Objections to the form of a question or answer, errors and irregularities occurring at the oral examination in the manner or taking of the deposition, in the oath or affirmation, or in the conduct of any person, and errors and irregularities of any kind which might be corrected if promptly presented, are waived unless seasonable objection thereto is made at the taking of the deposition.
(3) Objections to the form of written questions are waived unless served in writing upon the party propounding them within the time allowed for serving succeeding questions and, in the case of the last questions authorized, within 7 days after service thereof.
(4) A motion to suppress is unnecessary to preserve an objection seasonably made. Any party may, but need not, on notice and motion obtain a ruling by the court on the objections in advance of the trial.
(d) As to Completion and Return of Deposition. Errors and irregularities in the manner in which the testimony is transcribed or the deposition is prepared, signed, certified, sealed, indorsed, transmitted, filed, or otherwise dealt with by the officer are waived unless a motion to suppress the deposition or some part thereof is made with reasonable promptness after the defect is, or with due diligence might have been, ascertained.
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.
Frequently Asked Questions
What happens if a party doesn't object to a defective deposition notice right away?
The objection is waived — Rule 211(a) requires prompt written objection.
When must a party object to the person taking the deposition being disqualified?
Before the deposition starts, or as soon as the disqualification is discovered or reasonably could have been.
Do objections to a witness's competency need to be raised during the deposition?
Only if the problem could have been fixed at the time — otherwise they can wait until the testimony is offered at trial.
Is a formal motion to suppress required to preserve a timely objection?
No, a seasonable objection preserves itself, though a party may still seek an advance ruling by motion.
How does a party challenge errors in how a deposition was transcribed or filed?
By a motion to suppress, made promptly after the defect is discovered or should have been.
Committee Comments
This rule is derived from former Rule 19-9. The language is unchanged except that the period for filing objections to the form of written questions has been extended to seven days in subparagraph (c)(3) in keeping with the committee’s policy of measuring time periods in multiples of seven days.
