+\subsection{Aborting A Penalty}
+\label{sec:aborting_penalty}
+
+If a penalty was incorrectly applied to a robot and acknowledged by the referee to be incorrect, the robot should first be removed and placed outside the field, following the same process for the Standard Removal Penalty (see \cref{sec:removal_penalty}). Once placed, the robot should then be allowed to continue play immediately after being placed and the GameController removes its penalty.
+
+The aborted penalty will not be added to the total team penalty count and will not increase by \qty{\StandardPenaltyIncrease}{\second}, according to the standard removal penalty rules.

+\subsection{Drop-Ball Rule}
+\label{sec:drop_ball_rule}
+
+In the event that there has been a referee error or a pause in game during the \texttt{playing} state and has been acknowledged by the head referee, the drop-ball rule shall apply.
+The game must stop and will start again when the arising issue has been resolved.
+
+When resuming the game, the process should be the same as an initial kickoff as specified in \cref{sec:initial-kick-off}, placing the robots on the sidelines.
+However, none of the teams will be given kickoff, and no team would be allowed in the center circle until the \texttt{playing} state as there is no longer time allotted for kick-off.
+The ball will be placed on the center marker as standard for a kick-off.
+The only current situations where the drop-ball rule would be required is when a referee timeout or a global game stuck has been called.

+\subsection{Ball Stop Rule}
+\label{sec:early_stopping}

+If a game half were to extend longer than the allotted time, due to an attack situation by a team, the half should end if the ball comes to a complete stop or when the ball leaves the field, with no immediate play by other robots.

-The assistant referees can \textit{indicate} violations against the rules committed by robots to the head referee, so that the head referee can decide whether to penalize a certain robot or not.
+The head referee should talk to the assistant referees before the game starts to determine what tasks or lesser decisions they wish to delegate to them, however the final calls must come from the head referee.
+Examples of delegated assistance to referee decisions include keeping track of indirect-kick rule compliance to help confirm if a valid goal has been scored and indicating possible rules violations requiring a penalty (such as leaving the field, or motion in set).

 Assistant referees should only enter the field to execute a decision made by the main referee.
 They should not prevent robots from falling during the game.

+During the RoboCup competition setup days and during the game days, several teams may want to participate in friendly games with each other.
+In this case, there should be a list of all the head and assistant referees that are willing to judge a game.
+The referees on the list should be voluntary but participation should be encouraged.
+This is especially recommended for those who wish to gain referee experience.
+Teams are still free to choose their own referees.
+
+The OC should be in charge of maintaining the list and should be approached if one should want to volunteer.
