What has changed?

On Feb. 6, 2011, I posted this thread, Conflict of Interest???  At the February 8 meeting, Joe DeIuliis voted in favor of all requests made concerning the high school project.  The Solicitor as well as Joe explained how there was no conflict of interest even though Joe was the business development manager, Pittsburgh region for dck worldwide.  dck worldwide bid on the high school renovation.

Fast forward to the 11/14/11 meeting.  Joe DeIuliis would not introduce or vote on item 12 of the 11/14/11 Commission meeting agenda.  His employer, dck worldwide, was bidding on the project.  Would someone please explain to me why it is a conflict of interest now, but it wasn't a conflict of interest when dck worldwide bid on the high school project?
