Fiba lane violation interpretation
 

FIBA rules

On a freethrow, Is a lane violation created when a foot 'breaks the vertical plane of the lane', or when the foot touches the court surface inside the lane before release?

Havent had much success looking this up. While Ive read in certain USA rule variants that its crossing the vertical plane, in fiba rules and interps I can only see references to 'entering early'. So can a player in a marked lane extend the foot but keep it raised, only touching the lane after release?

If you are questioning whether:
1) the player's foot was extended into the lane but NOT touching the surface of the floor while the ball was in-flight.
or
2) does the simple action of the foot 'breaking' the vertical airspace constitute a lane violation?
I'm imagining how this would work, the ball is in-flight by ft shooter, the opponent steps into the lane but keeps the foot off the surface, but it may appear that it was on the floor.

In NFHS rules, it doesn't matter if the foot hits the floor. Breaking the plane is a violation.

How tightly it's called is another matter.

And I have no idea about the metric rule.

Thanks for the replies, and yep saw in googling about the NFHS rules, but FIBA doesn't mention breaking the plane in the rules specifically, just not to 'enter' until the ball has left the hand. So hoping a fiba familiar person might have seen it referenced in interpretation guidelines or exam questions etc.

It's never something that has come up in any of our meetings... hopefully the free throw is successful and the violation can be ignored!

We use FIBA rules here in the UK, and the call is when the foot touches the floor, makes for interesting balancing when the foot is on the way down and the ball is still in hand...

But, as said earlier, hopefully the ball drops so who worries about a foot? :p
