Minn. R. Crim. P. 21.08
The parties may by written stipulation provide that a deposition may be taken before any person, at any time or place, upon any notice, and in any manner, and that it may be used like other depositions. These rules, unless inconsistent with the stipulation, govern the taking of the deposition.
Minn. R. Crim. P. 21.08
Comment-Rule 21
The requirement that a qualified interpreter be present for defendants disabled in communication is based upon Rule 8 of the General Rules of Practice for the District Courts and Minn. Stat. §§ 611.31-611.34.
The deposition may be taken before any person authorized to administer oaths designated by the order. If the deposition is taken outside the State of Minnesota, this would include any person authorized to administer oaths by the laws of Minnesota or of the state where the deposition is taken. See Moore v. Keesey, 26 Wash.2d 31, 173 P.2d 130 (1946).
Notice must normally be personally served on the defendant. But, in cases where the defendant is unavailable and time is of the essence, the court may order that notice be served on the defendant's attorney instead of the defendant. These rules do not deal with the constitutionality of the use of a deposition at trial when the defendant has not been personally notified.
Rule 21.05 does not require that the deposition be submitted to and signed by the witness. It requires only that the person before whom the deposition is taken certify that the deposition is a true record of the testimony given by the witness. Any dispute over the accuracy of the record must be dealt with under Rule 21.07, subd. 4 (completion and return of deposition).
