Confusion on Backcourt

[refiator]

Neither of these is a BC violation.
In the first, the player was still considered in the front court since he alighted from the front court when the ball was thrown.
In the second, no team control exists, so there can be no backcourt violation.

I once had a partner who called a a BC violation on a throw in- The thrower passed the ball at mid-court and a player jumped from frontcourt, caught the ball and landed in the backcourt. Since team control did not exist when he jumped, it was legal to catch the ball then land in BC. (In this case I blew my whistle, conferred, and gave the ball back to that team fo a throw in - a do-over.There is nothing in the rule book to to support this, but it is the right thing to do.
