Not all foul play is equal. The IRB recognises that - it does not insist on a card for a "reactionary" high tackle.[TEXTAREA]Clarification 9 of 2004I don't believe "foul play" is that ambiguous... It's anything covered by Law 10 (which includes dangerous play).
If a penalty try is awarded as the result of a player unintentionally offending, the player, as well as being liable to cautioning and temporary suspension or send off, can be admonished by the referee. [/TEXTAREA]
Once againI think we have to interpret the laws sensibly rather than try to do so literally (and we cannot guarantee an agreed meaning anyway).
