30.221—May the judge limit the time, place, and scope of discovery?
         Yes. The judge may limit the time, place, and scope of discovery either:
    
    
        
        (a) 
         On timely motion by any interested party, if that party also gives notice to all interested parties and shows good cause; or
    
    
        
        (b) 
         When the judge determines that limits are necessary to prevent delay of the proceeding or prevent undue hardship to a party or witness.
