# One-wall · Rule 3.7 Appeals · B. How to appeal

A player must make appeals directly to the referee before the referee announces the score,

called “second serve” at the appropriate time after a fault serve, or called “first/second serve, one serve” at the appropriate time after a hinder serve,

before the next rally. The referee will then request the opinion of the line judges. The referee may also appeal to the line judges if he/she is uncertain of his/her own call, and may then maintain, reverse or nullify the call in question. A replay shall be called if the referee believes it is necessary in the interest of fairness.
