Sport is an increasingly important area of society both inside and outside of the school environment although this has not always been the case. Greater interest in sports policy is also emerging at both a European and International level with the prospective of a "Rights" based approach developing. The safety of those playing sport is fundamental and this is more problematic in those games where there is physical contact and an element of risk taking. Pressure to protect participants from injuries caused by mismatches in strength and weight is likely to increase because of the concussion litigation. This paper discusses the potential for liability for injuries caused within junior rugby, taking into account the current parameters to existing liability and the potential influence of relative age effects. It is foreseeable that in the future players will have to be assessed for their suitability to play contact sports based on factors other than age.
