Enforcement of Rule 10

[archangel]

I would NEVER walk off the field/court after an overrule by my partner. I probably wouldnt work with him/her again if I felt strongly on my call. Leaving the game before it ends sends a message, of the type of official you are, to all concerned, including assignors and fellow officials- kinda like an unhappy kid saying "its my ball" and walking away with it.
Finish the contest, explain clearly your position in post game, and inform the assignor. Let your partner look bad.
