RULE 1.3
                           EFFECT

    Except as otherwise provided elsewhere in these rules, on their
effective date:
    (a) Any acts done before the effective date in any proceedings then
pending or any action taken in any proceeding pending under rules of
procedure in effect prior to the effective date of these rules and any
constitutional right are not impaired by these rules.
    (b) These rules also apply to any proceedings in court then pending or
thereafter commenced regardless of when the proceedings were commenced,
except to the extent that in the opinion of the court, the former procedure
should continue to be made applicable in a particular case in the interest
of justice or because of infeasibility of application of the procedures of
these rules.
