This rule is intended to implement Minn.R.Civ.P. 43.07.
Advisory Committee Comment-2006 Amendments
Interpreters who have not been qualified as experts should not be allowed to provide their opinion about the content of questions and answers involving persons who do not speak English or are handicapped in communication. The specific rules governing the qualifications of interpreters are set forth in Minn. Gen. R. Prac. 8. This rule provides that an interpreter who is listed on the statewide roster as a certified court interpreter is presumed competent to interpret in all court proceedings. Minn. Gen. R. Prac. 8.02(a). Most court interpreters on the statewide roster, however, have not passed the stringent tests and are not certified. Interpreters on the statewide roster but not certified, or those interpreters not on the roster, must be qualified as expert witnesses before providing interpretation. Judges should use the screening standards developed by the State Court Administrator to determine whether the non-certified interpreter is qualified. See Minn. Gen. R. Prac. 8.02(c).
