Please see below (with emphasis added); it is Section 16 of the PDP Manual:

"Approved GNSO Council policies may be modified or amended by the GNSO Council at any time prior to the final approval by the ICANN Board as follows:

  1. The PDP Team is reconvened or, if disbanded, reformed, and should be consulted with regards to the proposed amendments or modifications;

  2. The proposed amendments or modifications are posted for public comment for not less than thirty (30) days;

  3. The GNSO Council approves of such amendments or modifications with a Supermajority Vote of both Houses in favor." 


I hope this helps.

Cheers
Mary
