SECTION FOUR
CALL OUT OF ROTATION

LAW 28 - CALLS CONSIDERED TO BE IN ROTATION 

A. RHO Required to Pass

A call is considered to be in rotation when it is made by a player at his RHO's turn to call if that opponent is required by Law to pass.

B. Call by Correct Player Cancelling Call out of Rotation

A call is considered to be in rotation when made by a player whose turn it was to call, before a penalty has been assessed for a call out of rotation by an opponent; making such a call forfeits the right to penalise the call out of rotation, and the auction proceeds as though the opponent had not called at that turn, but Law 16C2 applies.
