backcourt questions, and line neutral?

[mutantducky]

A1 in the backcourt passes to A2 who catches the ball with one foot in the frontcourt. Edit- Second foot is in the backcourt. A2 then throws a pass to A3 who jumps from the backcourt and lands in the frontcourt. Violation?
2. Same but A2 catches with both feet in the backcourt and dribbles once in the frontcourt. A2 then does the pass to A3.

Midcourt line, division line or whatever people call it. Is the line neutral? By that I mean if A2 foot is on the line but not in the frontcourt is it still in the backcourt. Same with a dribble on the line and if the ref can’t tell if it is advanced do you wait for one more to tell if it is clearly over.


I think I saw somewhere here that only when dribbling does the 3 points count, is that true? If that is then I’m thinking 1 is a violation and 2 isn’t.
