Ruapehu Rugby Club is threatening to withdraw from the Weekes Cup this year because it claims a rule change gives another club an unfair advantage.
The Weekes Cup is decided on the aggregate of competition points a club can achieve in the qualifying rounds of both the Premier and Senior competitions.
At December's Council of Clubs' meeting, a contentious 4-3 vote saw Wanganui Marist's motion passed where all club teams in those grades can be eligible to contribute their aggregate for the Cup.
Currently Marist is the only club with three teams eligible their Premier side and two Senior squads.
Ruapehu cried foul and has given an ultimatum either change the rule back or they will not contest the Cup in 2013.
