Depositions may be taken before any of the following persons except an attorney, or employee of an attorney, for a party or prospective party and except a person who would be disqualified to act as a juror because of interest in the event or consanguinity or affinity to a party: 1. within the state, a person authorized by the laws of the state to administer oaths; 2. without the state but within the United States or within a territory or possession subject to the jurisdiction of the United States, a person authorized to take acknowledgments of deeds outside of the state by the real property law of the state or to administer oaths by the laws of the United States or of the place where the deposition is taken; and 3. in a foreign country, any diplomatic or consular agent or representative of the United States, appointed or accredited to, and residing within, the country, or a person appointed by commission or under letters rogatory, or an officer of the armed forces authorized to take the acknowledgment of deeds. Officers may be designated in notices or commissions either by name or descriptive title and letters rogatory may be addressed "To the Appropriate Authority in (here name the state or country)."
(b) Oath of witness; recording of testimony; objections; continuous examination; written questions read by examining officer.
The officer before whom the deposition is to be taken shall put the witness on oath and shall personally, or by someone acting under his direction, record the testimony. The testimony shall be recorded by stenographic or other means, subject to such rules as may be adopted by the appellate division in the department where the action is pending. All objections made at the time of the examination to the qualifications of the officer taking the deposition or the person recording it, or to the manner of taking it, or to the testimony presented, or to the conduct of any person, and any other objection to the proceedings, shall be noted by the officer upon the deposition and the deposition shall proceed subject to the right of a person to apply for a protective order. The deposition shall be taken continuously and without unreasonable adjournment, unless the court otherwise orders or the witness and parties present otherwise agree. In lieu of participating in an oral examination, any party served with notice of taking a deposition may transmit written questions to the officer, who shall propound them to the witness and record the answers.
(c) Examination and cross-examination.
Examination and cross-examination of deponents shall proceed as permitted in the trial of actions in open court. When the deposition of a party is taken at the instance of an adverse party, the deponent may be cross-examined by his own attorney. Cross-examination need not be limited to the subject matter of the examination in chief.
