The EHF-IHF impasse over IHF plans for a new qualification format for the World Championships and a World League appears to not be heading towards a peaceful resolution. At the EHF Presidents meeting in Vienna last week 47 EHF members agreed to propose 12 motions at the next IHF Congress in April 2007. Foremost, the EHF is proposing that the IHF be restructured and that an Extraordinary Congress be held 3 months later to hold new elections. These motions raise the stakes significantly for the IHF leadership as they are essentially a threat to vote them out of office halfway into their 4 year term.

According to Article 14 of the IHF By-laws http://www.ihf.info/upload/PDF-Download/Regulations/01_-_Bylaws.pdf only a simple majority is required to request an Extraordinary Congress. The IHF has 160 members, so the EHF with 47 members can not reach a majority alone. Hence their recent meetings with the Asian and African Federations to develop a consensus majority voting block.

Additionally, the EHF is also proposing to hold the World Championships only once every four years. The proposed sequence of events would be

2012 Olympics
2013 Continental Championships
2014 World Championships
2015 Continental Championships

As far as when this change would take place, the EHF article does not go into detail. The 2009 World Championships have already been awarded (Croatia- Men, China- Women), but they could probably be moved to 2010. Additionally, the EHF has already awarded their 2010 European championships. As the Continental Championships would move to odd years a transition, in which there is either a short 1 year or long 3 year gap would have to be decided upon
