I'll just say that you have significant concerns from many different indigenous leaders. It's not their job to police the specific enforcement of the program. They're seeing a problem in general.
You would expect that government departments would be able to assess these bids and identify the problems. When you don't have a single case identified by the government, it suggests that there's a lack of interest, a lack of capacity or whatever it is, to actually enforce the basic parameters of this program.
Isn't it your job to...well, maybe not yours as particular individuals, but isn't it the government's responsibility to enforce this program and not that of indigenous leaders, who are outside of government?
