There wouldn't be a case in the first place. If she (Rebbecca) haven't maintained the boy's Qatari Nationality. There is a Qatari embassy in Bahrain, she could have canceled it! It is almost 5 years since the biological father died.

why keep the Qatari nationality? Can you kindly explain that?

This case would have never went to court & she would have easily won the kidnapping case if Adam had only his British nationality
