At the recently concluded All England, there was a fault called in the Men Singles Final. Umpire is heard to tell player he faulted "... too close" The video clip of that rally is here -- Since when is that a fault? The laws does not mention any such thing. Did the umpire err in communication? Was there a fault? If so, who was at fault?
The umpire should have said "My critical thinking has enabled me to gather information about the shuttle and your racquet position, verified that your racquet was too close to the striker on my left, and develop a holistic solution that I have just conveyed to you. Now stop faffing about and play on."
