TAP League Ruling????

Can somone please tell me what the official ruling on the following scenario would be under TAP League rules for 8 ball.

Here is the situation:
I am on the 8 ball and it is my opponent's shot. He has 1 ball on the table that he is shooting. In order to shoot his ball he has to shoot so that his back part of the cue is over the 8 ball. Upon executing his shot his back hand hits the 8 and moves it forward almost 3 feet. My opponent makes the shot but the cue ball also goes around the table and passes directly through where the 8 ball would of been sitting had he not moved it. The cue ball never actually touched the 8 ball. Does this constitute a foul with me having ball in hand? Does my opponent get to stay at the table with my decision if the 8 stays where he moved it or I can move it back to where I thought it was supposed to be prior to the hit? We looked in the rulebook but nothing stated if the ball moved was the 8. The fact that the cue ball would of hit the 8 if it was not moved therefore impacting the final travel path of the cue ball and the 8 ball. Nobody could agree on the findings of this situation. Even people who have been referee's at national Tap events nor the League Operator. So I wanted to ask on AZB and see if a senior official in Tap could answer this question.

Thanks
Chris

Shakeysmooth thanks for the reply are you an official in Tap? On what grounds are you basing your response on? I don't see anywhere in the rules where it defines this situation. I am not questioning you I am just looking for a solid answer to bring to my league director. Fyi we did call it a foul with ball in hand. Here is the ruling from the Tap rulebook.
Accidental Movement of a Ball
–
If a player moves the cue
ball, in any way, prior to their shot it is a foul and results in ball-in-hand
to the player’s opponent; this does not apply in ball
-in-hand situations
when a player is placing the cue ball. However, should a player
accidentally move, or pocket, any other ball(s) in preparing to shoot or
in the execution of a shot, it is not a foul (NOTE: Should a player
accidentally pocket the 8 ball, it is loss on game.) The opposing player
has the right to replace the ball(s) or leave them where they are. Should
the shooter, by reflex action, attempt to replace the moved ball(s), this
is not a foul, but the opposing player has the option of placing the
ball(s) back to where they were originally resting or leaving them
where they were moved to by the shooter. If a player touches any
moving ball, moved as a result of the shot, or the moved ball is struck
by another moving ball during the shot, it is a ball-in-hand foul for the
opponent. If any moving ball strikes the shooters cue, bridge stick or
their person it is a ball-in-hand foul to the opponent. NOTE: (If, after
missing a shot, a player swings their cue in disgust and hits any balls, it
is automatic loss of game.)

Thanks Blackcat for the reply. Does it matter that the cuebal passed right through where the 8 ball was had it not been moved. Therefore it disrupted the final path of both the cue ball and the 8 ball?
