One official calls a blocking foul on B1 and the other official calls a charging foul on A1. The try is successful. RULING: Even though airborne shooter A1 committed a charging foul, it is not a player-control foul because the two fouls result in a double personal foul. The double foul does not cause the ball to become dead on the try and the goal is scored. Play is resumed at the point of interruption, which is a throw-in for Team B from anywhere along the end line. (4-36)

And BktBallRef has recently given us some good advice on how do avoid the dreaded blarge:

Actually, I believe the quote from BktBallRef refers to when one official has a violation and the other has a foul. The majority of the board here says that when the officials in the above case play give conflicting preliminary foul signals they are obligated to report both. A few of us disagree. A preliminary signal is not binding in any other situation, why should it be here?
