On motion and upon such terms as are just, the court may relieve a party or his legal representative from a final judgment, order, or proceeding for the following reasons:
 
   
   (1) Mistake, inadvertence, surprise, or excusable neglect; 
   
   
   (2) Newly discovered evidence which by due diligence could not have been discovered in time to move for a new trial under 15-6-59(b); 
   
   
   (3) Fraud (whether heretofore denominated intrinsic or extrinsic), misrepresentation, or other misconduct of an adverse party; 
   
   
   (4) The judgment is void; 
   
   
   (5) The judgment has been satisfied, released, or discharged, or a prior judgment upon which it is based has been reversed or otherwise vacated, or it is no longer equitable that the judgment should have prospective application; or 
   
   
   (6) Any other reason justifying relief from the operation of the judgment. 
   
  The motion shall be made within a reasonable time, and for reasons (1), (2), and (3) not more than one year after the judgment, order or proceeding was entered or taken. A motion under this subdivision (b) does not affect the finality of a judgment or suspend its operation. Section 15-6-60 does not limit the power of a court to entertain an independent action to relieve a party from a judgment, order, or proceeding, or to grant relief to a defendant not actually personally notified as provided by statute or to set aside a judgment for fraud upon the court.
