Overruling your partner?

[Dan_ref]

This is idiotic.

By rule, one official cannot overrule (unilaterally overturn, make invalid, change or deny a decision) another official's call. Example: C calls 3 seconds on A1, T blows the whistle to declare A1 did not violate the 3 second rule. This cannot be done by rule.

However, any official can, by rule, bring potentially new information to the calling official at any time. Example: L gives the ball to B on an OOB off A1, C comes in to tell L that he saw the ball go OOB off B1. This is perfectly acceptable by rule. In this case the L decides whether or not the new information has standing and whether or not to change his call.

In practice, how & when it's acceptable to bring new information to the calling official is determined during the pregame.
