The ball was last touched by the defending team and then went over the goal line to the left side of the goal. The referee allowed the team to take the corner kick from the right side of the goal. I always thought that the corner kick must be taken from the nearest corner, and that it was not an option to move the ball to the other side. Assuming your answer is that the kick must be taken from the nearest corner, then could field conditions be taken into account for an exception.
Lets say that one corner is totally saturated with water and the other is dry.
If the ball went out on the wet side, could it then be moved to the dry side for the corner kick. In our situation, the left footed player simply wanted to take the kick with the wind behind him and from the right side, instead of into the wind from the left. The referee was mistaken in allowing the kicking team to move the ball to the other side of the field, whatever his reasoning may have been for that decision. Field conditions should not be taken into consideration for the placement of any restart. If the referee declares that the field is playable, then that includes all parts of the field and means that the field is safe enough for any restart to be taken where the Law specifies it should occur.
