For sure airport authorities should be held liable.
Ramp congestion has often led to improperly parked aircraft in that corner of DNMM,and as a result wide bodies on that taxiway should long ago have been forbidden.Am surprised they got that far as this is quite close to the threshold,and they would have taxied quite a distance past congested ramps where the creed for most crews familiar with that taxi way was "left of centerline"
Considering the same incident occurred with virgin atlantic A340 at the same spot in recent times,i would hope EMIRATES should hold the airport/atc liable.
Bunch of trainees in ground control doesn't help either.
