Suppose, I booked ticket in SL class from Navsari to Haridwar. But, forgot to change boarding point and finally remain unable to change it, due to booking within 24 hrs deadline.I boarded the train from Kota, after almost 16 hrs of booking point. I found the seat still remain vacant. I occupied it from Kota. TTE came later and told, my ticket stands cancelled as I didn't change boarding point and now I am an illegal traveller. Whether the TTE is right?
