Minn. R. Civ. P. 30.03
Examination and cross-examination of witnesses may proceed as permitted at the trial under the provisions of the Minnesota Rules of Evidence except Rules 103 and 615. The officer before whom the deposition is to be taken shall put the witness on oath or affirmation and shall personally, or by someone acting under the officer's direction and in the officer's presence, record the testimony of the witness. The testimony shall be taken stenographically or recorded by any other means ordered in accordance with Rule 30.02(d). If requested by one of the parties, the testimony shall be transcribed.
All objections made at the time of the examination to the qualifications of the officer taking the deposition, to the manner of taking it, to the evidence presented, to the conduct of any party, or to any other aspect of the proceedings shall be noted by the officer upon the deposition; but the examination shall proceed, with the testimony being taken subject to the objections. In lieu of participating in the oral examination, a party may serve written questions in a sealed envelope on the party taking the deposition and the party taking the deposition shall transmit them to the officer, who shall propound them to the witness and record the answers verbatim.
