It is the right of a Union to choose whatever team it wishes to be designated as its next senior national representative team. It is also the sole responsibility of a Union to ensure that players selected to play for the teams designated with IRB Regulation 8 are eligible to do so.
The IRB has reiterated to both Unions that during 2011 both Wales and France officially designated their Under 20 team to be the next senior national team. As the IRB has been advised that Shingler represented Wales Under 20 against France Under 20 in 2011 it would therefore indicate that he is tied to Wales and ineligible to play for any other Union.
The SRU and WRU may wish the IRB Regulations Committee to consider this matter formally in accordance with IRB Regulation 2. The Unions are aware of the requirements of such a review.
