A personal penalty , that is a caution or a suspension , rather than a team penalty , such as a free ball or a penalty corner , may be ( many would say should be or even must be , but again this is in the umpire 's discretion ) issued to the guilty party after an advantage allowed by the umpire has been played out in any situation where an offence has occurred , including dangerous play ( but once advantage has been allowed the umpire can not then call play back and award a team penalty ) .
