Once more, the question of a legal guarding position

[Damian]

It seems that the spirit of the rule is that according to our regional rep, a legal player is in bounds. If a person is touching the out of bounds line, he is not a legal player and as such cannot establish a legal guarding position.

He kept quizzing me on what is the playing area. I told him I was fine with that, but the word "touching" is where I had a problem.

After much discussion, the interpretation is that they must be in bounds.
