Off the IPF website:
"The General Assembly of the International Powerlifting Federation (IPF) held in Pilsen, Czech Republic 12 November 2017 voted with more than the requisite two-thirds majority to exclude Powerlifting Australia (PA), the Oceania Powerlifting Federation (OPF) and Mr. Robert Wilks (RW) from the IPF and its activities.
In principle, those motions come into effect immediately.
Mr. Robert Wilks raised the point that, if OPF and PA were excluded with immediate effect, it would not be possible for the OPF to host the IPF-sanctioned Oceania Championships & Pacific Invitational to be held 6-10 December 2017 in Singapore and for Australian lifters to participate under the banner of PA.
After duly considering this matter, the IPF Executive Committee proposed a solution which respected the will of the General Assembly to exclude PA, OPF and RW but also, in view of the proximity of the Oceania Championships & Pacific Invitational, took into account the interests of the lifters to participate. With those considerations in mind, the IPF Executive Committee made the following proposal:
The exclusion of RW from IPF and its activities, to take effect immediately.
The exclusion of PA and OPF from the IPF and its activities to take effect at midnight on 10 December 2017.
With effect immediately and until midnight on 10 December 2017, all rights of PA and OPF derived from or in connection with their status as a member federation and affiliated region of the IPF (respectively) are suspended, save to the extent necessary to organize, deliver and participate in the Oceania Championships & Pacific Invitational from 6-10 December.
RW was asked whether he agreed to this proposal, which he did without prejudice and reserving his other rights. The General Assembly was then asked to vote on this proposal, which they agreed with unanimously. RW asked whether he could continue to attend the General Assembly as an observer, which was permitted.
To clarify. The question has arisen if the above situation affects the membership of the other nations in the OPF. The answer is no. All OPF member nations except PA maintain their IPF membership unaffected. They remain all full members of the International Powerlifting Federation."
"For the last two years, the IPF and its EC have been subject to a persistent campaign by OPF, PA and Mr. Wilks. This campaign has involved inundating the IPF disciplinary bodies with claims (that the IPF EC considers to lack any merit), taking the IPF to the Court of Arbitration for Sport (unsuccessfully) and subjecting the IPF and the members of its EC to abusive and intolerable comments.
The campaign culminated earlier this year in a court action in Luxembourg in which the PA, OPF and Mr. Wilks are seeking the annihilation of the IPF as a federation together with an invalidation of all its competitions since 2010."
Since Wilks is the president/CEO of OPF and PA to get rid of him they needed to get rid of the whole federation.
Probably discussed on Reddit somewhere too, just search up the terms “IPF, Australia, Wilks etc.”
