Oh! Please do.
AV, over my professional career as a chemist, I belonged to several professional organizations. I know how they operate, and it is not the way you or your sources portray it. Meeting agenda's and proposals are sent to all members in advance of meetings.
Here is the IAU news release of that meeting in 2006.
IAU 2006 General Assembly: Result of the IAU Resolution votes | Press Releases | IAU
And a news release specific to Pluto.

And just in case you miss it, here are the specifics as to how the decision was reached.
"Q: How did astronomers reach a consensus for a new definition of planet?
A: The world's astronomers, under the auspices of the International Astronomical Union, deliberated on a new definition for the word planet for nearly two years. The results of these deliberations were channelled to a Planet Definition Committee and ultimately proposed to the IAU General Assembly. Continued evolution of the definition through debate and further discussion allowed a final consensus and vote."
NOTE THAT IT WAS DELIBERATED FOR TWO YEARS PRIOR TO THIS MEETING.
Again, it was not an ad hoc decision by just a few people.
There, AV. Absolute proof of what I previously posted is fact. Not something I made up as you incorrectly assert. What is your "sour grapes" source, some blog by non professionals?
GOT IT THIS TIME?
