history of backcourt

[so cal lurker]

After watching outrage at a freshman game when the officials (correctly) did not call a back court violation when a player stopped with one foot in the front court and threw the ball to a teammate in the back court, I was trying to remember back in the day. My recollection was that it used to be that once a foot was in the front court, it couldn't come back to the back court, nor could the ball be passed back. Did that used to be the rule, or was that just a misconception/myth from my playing days?
