The scrum must be stable, stationary and parallel to the goal-lines when the scrummie feeds the ball; otherwise a free kick is awarded to the non-offending team. By strict letter of the law, the ball must be fed into the middle of the tunnel with its major axis parallel to the ground and touchline; however this is becoming less strictly enforced.
Why this leniency...in the old days before the ref shouted the CTP&E (P removed and E is now set to save time) they just went in...all the other rules applied but the ball had to be fed (in one movement without fake), straight in the middle for the hookers to compete and without spin if I remember correctly.
The hooker had to be a smart "hooker" which added another competitive aspect to the game.... (as in line outs (no lifting then).
This is a contraversial subject of union that was no doubt influenced by league in a few areas...especially the older guys.
The line outs are fine but the scrums take too long still and are controlled and sometimes I believe manipulated by ref.
