How to Assign Old owner to case when someone try to assign new owner to case ?

Here I am preventing the case owner to be changed..by using triggers...by writing --  cc[0].OwnerId = Trigger.old[0].OwnerId;   

 

After this Even in Debug Logs, Old and new owner Id's are same and are equal to that of  Trigger.Old[0].OwnerId  ..... but In page layout after saving the case...Case Owner has te name of new owner?????

 

Can you suggest how to prevent the case owner from being changed ....And I don't want to through an error message.

 

if(!WGQueueName.isEmpty()){
  System.Debug('Inside WGQueueName not Empty');
  
  assignedCaseMetric = new Case_Metrics__c (Case__c = caseID, 
  Workgroup__c = WGQueueName[0].Name, CS_Case_Status__c = 'To Queue', 
                                                                   
  Assigned_Date_Time__c = datetime.now());  
  System.Debug('WorkGroup Name: ' +WGQueueName[0].Name +'\t WG Queue 
                Name: ' +WGQueueName[0].Workgroup_Queue__c); 
                        
  if(assignedCaseMetric != Null){
     Insert assignedCaseMetric;
     }
     
  cc[0].CS_Workgroup__c = WGQueueName[0].Id;
  cc[0].Workgoup_Email2__c = WGQueueName[0].Workgroup_Email__c;
}
                       
else{
  System.Debug('Inside else when WGQueueName is Empty');
  QueueSobject[] qq =[Select q.SobjectType, q.Queue.Name, q.QueueId, 
                      q.Id From QueueSobject q                      
                      Where SobjectType = 'Case' AND q.QueueId =: 
                      Trigger.old[0].OwnerId];

   System.Debug('Old Owner ID: ' +Trigger.old[0].OwnerId +'\t New Owner 
                 Id: ' +Trigger.new[0].OwnerId);

   cc[0].OwnerId = qq[0].QueueId;  
   
   System.Debug('Old Owner ID: ' +cc[0].OwnerId +'\t New Owner Id: ' 
                 +Trigger.new[0].OwnerId); 
                         
   }

System.Debug('Old Owner ID: ' +cc[0].OwnerId +'\t New Owner Id: ' +Trigger.new[0].OwnerId);

i'd recommend just a standard validation rule for this instead of a trigger.

Sorry but I  don't want to through an error message...that's not my requirement...and I need to implement with trigger only..Can you suggest how to prevent the case owner from being changed ....And I don't want to through an error message using validation rules. I just need if some one change the owner and save the case...the case will be saved with old owner not the new owner
