The Rules of Tennis are not merely technical guidance; each tour's regulations refer to them and make their application mandatory. A dispute over the application of a rule from this text is, under the tours' regulations, resolved on site by the match referee, whose decision on questions of fact is final.
The Federation reviews the text each year and publishes a separate amendments sheet. In a case concerning a rule of the game, the governing text is the one in force at the time the match was played.
