Well this doesn’t quite answer the OP. However the French have a Law, which says if the misconduct by the opposition prevent a conversion or penalty kick from being taken before the match ends. Then the referee awards the points for the kick.
[LAWS]Si l’arrêt de la rencontre intervient après qu’une tentative de but, accordée à l’équipe non fautive (but après essai ou coup de pied de pénalité), a été empêchée par les agissements de l’équipe adverse, l’équipe non fautive obtiendra le bénéfice du but.[/LAWS]Okay it doesn’t help for restarts after an incorrectly taken PK, but came up it another discussion and seemed relevant to my way of thinking. Probably only needed because of “all” the match ending mass brawls this side of the channel.
