If that is the case then BSPL/SCB/ACU needs to stick to their guns and revoke his licence, not consider him for any competition or nomination and move on
That then needs to be a permanent move - he may not need any of that now but if/when he may do in the future it has to still be in effect
I believe the same requirement is in place in Sweden,Denmark and Poland regarding riding in their domestic league in order to gain start permission elsewhere - I don't hear such an outcry from them
On that basis theres nothing to stop the line being a metre wide and by your definition being on it would still be on track...
I'd say its quite clear - the chalk marks the inner edge of the track surface
Therefore the track ends as soon as the line starts
But switched to a British licence as the German Federation wouldn't nominate him in the GP qualifiers when he needed it
Have cake and eat it comes to mind....
