From the 2012-13 NFHS Rule Interpretations:
SITUATION 1: While A1's free throw is in flight, B1, in a marked lane space, enters the lane. A1's free throw hits the ring and bounces straight up and hits a wire over the basket or hits the ring and goes over the backboard. RULING: The official should sound the whistle and call a violation on B1. A1 is given a substitute free throw. (9-1-4 Penalty 2b)
The ruling seems counter to Rule 9-1 Penalty 4b: "If there is a violation first by the free-thrower's opponent followed by the free thrower or a teammate: If the second violation is by the free thrower or a teammate behind the free-throw line extended and the three-point line, both violations are penalized, as in penalty item (3)."
It also seems counter to case book play 9.1.3 Situation H where B1 enters the lane early followed by free throw shooter A1 stepping on the line. In that case, the ruling is a double violation and go to the arrow.
What's the basis for this ruling?
