Our opponent was serving to my partner. I was moving my feet in place just to keep from being sedentary. Not wildly, just kind of shuffle back and forth in place. The server missed and blamed me for moving. Said I am not allowed to move while opponent is in the service motion. I let her take the serve over but I don't think that is right. What is the rule on this?
Note: This is regarding the partner of the receiver, not the receiver themself.
It is possible under the rules to be called a hindrance according to the ITF Rule book
If a player is hindered in playing the point by a deliberate act of the opponent(s), the player shall win the point.
Case 5: In doubles, where are the server’s partner and receiver’s partner allowed to stand? Decision: The server’s partner and the receiver’s partner may take any position on their own side of the net, inside or outside the court. However, if a player is creating a hindrance to the opponent(s), the hindrance rule should be used.
As to whether the movement of the partner of the receiver is hindering could be up for debate, but consider this... how far does it go? Could they start jumping up and down waving their arms or yelling out at the time of the serve be considered a hindrance?
In a recreational match, such rules are hard to enforce as there typically is no umpire and it is down to the players themselves being honest and fair.
