Heriodd Llywodraeth Cymru y penderfyniad hwn o'r dechrau. Yn 2010, yn sgil cryn dipyn o drafod, cofnodwyd y mater yn ffurfiol fel anghydfod rhynglywodraethol. Ar 8 Mehefin eleni, trafododd y Cyd-bwyllgor Gweinidogion hyn a helpodd i ddatrys rhai problemau. Cadarnhaodd hefyd frwdfrydedd y gweinyddiaethau i’w datrys mewn ffordd greadigol ac adeiladol er mwyn sicrhau llwyddiant Gêmau Olympaidd 2012.
The Welsh Government disputed this decision from the outset.  Discussions reached the point in 2010 where the matter was recorded formally as an inter-governmental dispute.  This was discussed by the Joint Ministerial Committee (JMC) on 8 June of this year and that helped to clarify unresolved issues in the dispute.  It also confirmed the administrations’ shared interest in resolving those issues creatively and constructively with a view to ensuring the success of the 2012 Olympic Games.
