Minn. R. Evid. 706
Committee Comment-1977
This rule implements rule 614 setting up the appropriate procedure to be used in calling an expert as a court witness. By recommending this rule the committee did not intend to encourage the use of court appointed expert witnesses. In the appropriate case, a trial judge might find that the use of a court expert would be necessary to a fair, expeditious, and inexpensive proceeding. See, e.g., Minnesota Statutes, section 176.391(2) (1974) which provides for the appointment of impartial experts in Workmen's Compensation proceedings.
However, court experts pose a potential danger. Particularly in a jury trial such an expert might unfairly tip the balance in the adversary process. The rule provides for ample opportunity for the parties to provide the court with the necessary information with which to make the decision whether to call an expert as a court witness.
