Changing your partner's call

[DownTownTonyBrown]

Jurassic, I'm glad we are still on the same page. Not sure why others aren't seeing our point.

• One action (foot location)
  two different viewers
  have two different perspectives of actual foot location
  Primary official says foot WAS NOT on the line and signals for 3-point attmpt.
  Secondary official says foot WAS on the line and stops game to "correct" Primary official's 'obvious' error.
  Both officials are fully confident their respective calls were correct.

Who has final authority? Whose call/perception is correct?

Per this, seemingly innocent guidance, the Secondary official is given final authority to correct the Primary official without further consideration... and many here are willing to accept that. Go figure. Oh well.
