A London court has reinstated nationality rights of two British-Bangladeshi men ruling that they were wrongly stripped of their citizenship.

The UK government earlier revoked the citizenship of the duo after they were wrongly assessed as dual nationals, reports the Middle East Eye.

Judges at the Special Immigration Appeals Commission (SIAC) said in a ruling published on Friday (Nov 17), that the British government had wrongly determined that the two men, who are identified only as E3 and N3 to protect their identities, were British-Bangladeshi dual nationals and could, therefore, be served with citizenship revocation orders.

Both of the men have families with roots in Bangladeshi. One was born in Bangladesh and the other was born in the UK. But the court ruled that both had lost their Bangladeshi citizenship when they were 21, and had never taken any positive action to keep it.

The SIAC ruling could have legal implications for many more cases involving British citizens who have been subjected to the highly controversial and legally contentious citizenship deprivation orders in recent years because of government concerns about the threat of suspected fighters returning from Syria, the report said.

One of the men, N3, said that he had been stranded in Turkey for more than a year due to the case, and had been involved in aid work in the country helping Syrian refugees. E3's case, however, is not Syria-related.

Speaking after the ruling was published, N3 said he was innocent of any wrongdoing.

“I feel that my country stabbed me in the back by removing my citizenship right after I left the UK last year to return to running my business and carrying out important aid work in Turkey,” Middle East Eye quoted him as saying.

“Hopefully now the courts will force the Home Office to stop taking people’s citizenship away without any right - it’s a practice that belongs to medieval times.”

The Home Office stripped both the men of citizenship on grounds of “terrorism-related and national security.”

But the orders can be issued on the basis of suspicion alone, with no requirement for the recipient to have been charged or convicted with any offence, providing that the Home Secretary deems that their presence in the UK is “not conducive to the public good” and doing so does not render them stateless.

The UK is widely considered to have the most extensive citizenship-stripping powers of any Western state, with lawyers and human rights campaigners comparing the process to “medieval exile”, the report said.
