Cardiff won the inaugural Welsh-Scottish League.[1] However they lost their final match against Swansea at home thus losing an unbeaten home record that dated back to December 1997.[2] The points system was complicated by the Rugby World Cup and only two points were awarded for a win prior to November 1999. Both Cardiff and Pontypridd were deducted points by playing Edinburgh during this World Cup period; although the matches were scheduled to take place outwith the World Cup.[3] [4]
The top 5 Welsh teams plus Edinburgh and Glasgow qualified for next season's Heineken Cup.
