Human Factors; Procedure
I was working Ground Control and Controller in Charge position. I was over seeing the operation when I noticed the Cessna on landing roll when the RV was almost over the threshold on the same runway. I ordered the Local Controller to send the landing RV around. The Local Controller refused. I again ordered the Local Controller to send the RV around because there was not 3;000 feet between the Cessna on landing roll and the landing RV. Again the Local Controller refused.  Runway separation was lost and a runway incursion occurred.This is a controller judgment issue not a system issue. This controller continuously puts aircraft under his control and other controllers aircraft in danger on a daily basis. Nothing is being done about it. I recommend decertification.
An ATC Controller in Charger reported the Local Controller refused their instructions to send an arrival around due to insufficient runway spacing between subsequent arrivals.
