A1, in his frontcourt, is dribbling parallel to, and very close to, the division line.

While dribbling, A1's right foot touches the division line, but not while his hand is in contact with the ball (between dribbles).

Ball never touches (or goes beyond) the division line.

A1's right foot returns to the frontcourt and only then does his hand touch the ball, and he continues his dribble parallel to, and very close to, the division line.

By NFHS definition, the division line is not considered to be a "boundary line".

4-9-1: Boundary lines of the court consist of end lines and sidelines.

We do have a NFHS rule that tells us what to rule if a dribbler does such a thing at a "boundary line".

9-3-1-Note: The dribbler has committed a violation if he/she steps on or outside a boundary, even though he/she is not touching the ball while he/she is out of bounds.

But the NFHS does not consider the division line to be a "boundary line".

What do you have?

Intent and purpose?
