Technical Foul Admin

[ltllng]

A large number of officials believe that the players must retreat to behind the half court line for administration of a intentional or technical foul shots.
I have seen this at all levels, NBA, College and high school, so that is why I have administered it this way and no one has ever told me I was doing anything wrong. I even beleive I was told by our rules interpreter that this was the proper way to handle the other 9 players, as the calling referee administers the shot and the other referee keeps control of the 9 players.

Rule 9-1-8 only addresses the fact of players not occupying lane spaces must be behind the three point line above the free throw line extended.
But the intentional/technical foul penalty does not say the lane spaces must be clear.

Any one have any other comments or rule situtions on this?
I have searched through the case book and rule book for other adminstration with no luck.
