Plain-English Summary
Rule 28 answers a practical question every deposition depends on: who is authorized to administer the oath and take the testimony? Within the United States, a deposition must go forward before an officer authorized to give oaths under federal law, Arizona law, or the law of the place of examination, a person the court appoints for that purpose, or a certified reporter the parties designate under Rule 29.
Abroad, the options widen: a deposition may proceed under an applicable treaty or convention, under a letter of request (sometimes called a letter rogatory), on notice before someone authorized to administer oaths where the deposition is taken, or before a person the court commissions for that purpose. Evidence gathered through a letter of request does not have to be excluded just because it isn't a verbatim transcript, wasn't taken under oath, or otherwise departs from how a deposition would normally be taken in the United States.
A letter of request or commission is not required at all for a deposition taken in a pending Arizona case — the clerk issues one only on request, after notice to the other parties, and without needing to show that any other method of taking the deposition would be impractical. A party who wants to object to the form of a letter of request or commission must do so in writing before the clerk issues it, or the objection is waived.
Finally, the rule disqualifies certain people from presiding over a deposition altogether: a party's relative, employee, or attorney; anyone related to or employed by a party's attorney; and anyone with a financial stake in the outcome of the action.
